PREFACE

ADAPTIVE JAKARTA studio pays attention to the role of landscape architects in rapidly growing Asian cities; our perspective in identifying urban issues, discovering opportunities through design interventions, and advancing proposed interventions into sustainable strategies for the betterment of the residents. Students were challenged to analyze the socioeconomic drivers of spatial usage and patterns from community-level as well as city-wide geographical context to better understand the complex dynamics of the city as a whole. This book is a compilation of 19 graduate students’ work in the Landscape Architecture program, who put their hearts and efforts to explore adaptive landscape design interventions for creating multi-functional and culturally sensitive public spaces for enhancing city’s liveability. The first half of the book documents the process of the studio chronologically; group’s site analysis to explain the context and motivation for subsequent design approaches, and ends with design suggestions with concepts and experiential graphics. 19 very diverse design outcomes appear in the second half of the book under the following categories: 1) Waste & Landfill, 2) Wastewater Treatment, 3) Storm -water & Flood Risk Management, 4) River System Reconfiguration, 5) Social & Lifestyle, 6) Community & Open Space, 7) Streetscape and Linear Infrastructure. The book concludes with reflections of the studio. We hope the book will contribute to the deepening of the knowledge-base and an expanding of the potential scope of our profession. The studio preparation and site visits owe a lot of support from Mr. Brahmastyo Puji from Architecture Sans Frontières, Ms Elisa Sutanudjaja, executive director of Rujak Center for Urban Studies in Jakarta, Ms. Ellisa Evawani, Associate Professor, and Ms Hanifa Wasnadi from the University of Indonesia, and their students from the Department of Architecture, Faculty of Engineering, Ms. Dewi Rezalini from Bogor Agricultural University, Department of Landscape Architecture for sharing her insights of the profession in Indonesia. Special thanks to guest reviewers, Ms. Dixi Mengote-Quah, Ms. Dorothy Tang, Ms. Lehana Guo, Mr. Ryan Shubin who provided insightful comments to student’s works. Thank you very much.

STUDIO INTRODUCTION Ervine Lin and Kenya Endo

Course Overview | This studio-based module expands the skill level expected of our students by enlarging their mode of operation to the scale of the city. As the second installment of a four part masterlevel core studio, the students will visit the city of Jakarta, the current capital of Indonesia. There, they will be faced with the realities of an ever growing megalopolis stretched by both environmental as well as socioeconomic challenges. Students will be asked to explore how landscape architecture can potentially alleviate some of the issues to be uncovered over the course of the semester and to suggest socially acceptable, environmentally viable and technically innovative interventions using a landscape approach Background I Concerns over water scarcity, climate change, and environmental health risks have prompted some Asian cities to invest in river rehabilitation and scholars in recent years have been demonstrating that a change in paradigm in river rehabilitation is possible, providing future scenarios that balance concerns over flooding, water quality, and ecology, with the realities of a rapidly growing megacity like Jakarta, the current capital of Indonesia (Vollmer et al., 2015). By 2050, an additional 2.5 billion people, resulting in a total of 66 percent of the world’s population, is projected to reside in urban areas with a glaring majority of this increase concentrated in Asia and Africa (United Nations, 2014). This massive urban transition coincides with an unprecedented expansion of builtup land which has resulted in ramifications to the local-regional climate, pollution, water quality and availability, arable land as well as the livelihoods of people in the region (Schneider et al., 2015). Much of this growth occurs in the “mega-deltas cities” which have historically conglomerated people, resources and economic activities, a trend which increasingly places them at risk to environmental hazards (Seto, 2011) and has contributed to rivers and wetlands becoming one of the most threatened ecosystems in the world (Malmqvist and Rundle, 2002; Tockner and Stanford, 2002). One such city is the current capital of Indonesia, Jakarta. Unfortunately, increasing urbanisation, commercial development and centuries of exploitation and neglect have transformed the rivers in Jakarta, such as the Ciliwung River, into one of the most polluted rivers in the world (E. Satriastanti, 2012). The concurrent anthropogenic factors such as buildup of garbage (Texier, 2008) and the rapid subsidence due to groundwater extraction (Chaussard et al., 2013) have also been attributed to the ever increasing seasonal floods in the city, the latest deadly flood happening in January 2020 (CNA, 2020). The issue of flooding is further exasperated when municipal infrastructure fails to keep pace with urban growth forcing lower-income communities settled along the downstream section of the river to rely on the polluted river for water, sanitation and even recreation (Vollmer and Grêt-Regamey, 2013).

In the past two decades, multiple studies of water management problems and engineering proposals to mitigate flooding have been brought up in Jakarta but none have been successfully implemented (Silver, 2014). One of these proposals is the long standing plan to “normalise” the river channel, a project led by the Ministry of Public Works which includes dredging, expansion and bank reinforcement works that would change both the topography and land use along the riparian corridor. The high cost of land acquisition, sensitivity of aggressive demolition and eviction policies, ironically coupled with the allowance for commercial entities to develop along riverbanks and other

green spaces (Steinberg, 2007) have resulted in a fair amount of debate on the validity of the “normalization” process. Unfortunately, “normalization” is still the strategy which currently has the most momentum and residents of who have been residing along some of the worst hit areas live under the constant threat of eviction and relocation to make way for these river improvement works (The Jakarta Post, 2015). Those who have already gone through it are now physically and psychologically segregated from the water systems that flow through the city. The studio’s starting point is thus exploring means in which landscape orientated solutions might provide an alternative to the alienating approach of “normalization”. While rapid urbanization is often blamed for the environmental degradation and increasing hazards from natural disasters, the magnetic concentration of people, resources and economic activity in cities can also provide for an opportunity to create mitigation strategies that shift the city towards sustainability (Seto et al., 2010). This concentration of resources has allowed for river and wetland restorations to become an increasingly lucrative enterprise with billions of dollars being spent on restoration works (Nakamura et al., 2006) Seen no longer as merely a recreational or decorative exercise, the practice of river restoration can be viewed as an infrastructural investment in which a multitude of benefits can be obtained, inclusive of flood mitigation (Benedict and McMahon, 2006). Girot acknowledges this noteworthy endeavor of landscape recovery but challenges practice and discipline to engage with the cultural and environmental dimensions of a site through a combination of physical experience, intuition and scientific research (Girot, 1999). As such, while the situation in Jakarta might appear bleak, the studio seeks to engage with the local populance while bringing to the table a landscape architectural agenda which explores the possibilities of reimagining the water systems in Jakarta such that they play not only an ecological, social and economic role but also one which has the possibility to mitigate environmental factors.

Site I The primary landing site will be a community within Kampung Kedaung Kali Angke in West Jakarta, located along the riverside of Kali Apuran, and close to Cengkareng Drain. Dense single-story housing blocks are surrounded by industrial area and several high-class gated communities, as well as undeveloped open fields (presumably owned by private developers). Due to the river expansion program back in 2014, several houses were evicted, creating new composition of spaces along the river—linear inspection road with spontaneous communal activities, faced by 2 separated neighboring communities. This eviction along the river is a common theme seen along many parts of Jakarta to make way for normalization of the rivers and canals. The landing site serves as a snapshot for the studio to understand Jakarta’s community-level spatial organization, complexity of social structures, and challenges that a typical community faces toward sustainable living. Simultaneously, students are to investigate surrounding neighborhoods for contextual understanding, as well as to conduct city-scale analysis for identifying how our landing site interrelates with the dynamics of the Jakarta City as a whole.

Design Questions | During the course, students will be challenged to develop both spatially and socially compelling design interventions. The studio is designed to answer these questions by using Jakarta as a case study and Kampung Kedaung Kali Angke as a landing site to deploy and demonstrate each student’s design approach(es). Questions students should ask themselves can include but are in no way limited to the following: • Considering the complexity of the site and the city, what will be the key parameters / priorities? • Aside from simply pledging areas for green, how can we incentivize local stakeholders to be part of the drivers of your landscape proposal? • How will students address informality in design, when environmental pressure as well as infra• Can landscape architects propose design prototypes that can infuse greater diversity and livability into the urban context? Learning Objectives and Approaches | For a landscape intervention to be successful, designers need to understand the site in question—from its collective memory to its physical topography. Unfortunately a designer seldom (if ever) belongs to the place in which he or she is asked to operate ing) which serve as a theoretical methodology in which to extract as much potential from the site in thus be tasked to perform the following: 1. To step outside their comfort zone into the complexities of metropolitan Jakarta to experience the ground conditions for themselves (landing) 2. Carefully unfold the intricate characteristics of the site through detailed analysis and experiential explorations (grounding) 3. Discover the potential areas in which landscape architecture can be leveraged on to alleviate the 4. Propose ways to restructure elements of the city into a series of resilient outcomes in the form of bespoke spatial and social frameworks (founding) complex and is only one of the many facets in which students can consider as their intended focus. A nonexhaustive list of potential topics* is suggested below: • Urban hydrology including city-wide waterways and hydraulic infrastructures, collection of rainwater, ground water extraction, access to portable water, etc. • Interaction with water (access, behavior, perception etc.), and how they shaped people’s lifestyle. • Access to greenery (or lack thereof) within the city and the realities of park building in Jakarta. • Solid waste management and sanitation and the possibilities of reinvigorating a positive human landscape interaction. • Productive landscapes and their potential role in improving socio-economic divides.

Lastly, narrative development will be the overarching skills to be further developed. “Narratives intersect with sites, accumulate as layers of history, organize sequences and inhere in the very materials and processes of the landscape.” (Potteiger and Purinton, 1998)

services) and experience (distinctive and memorable). These challenges are to be developed into opportunities to serve as the foundation of a logical narrative to outline the advantages and necessities of the proposed design. Studio Structure I to understand site context, with in-depth input sessions from local experts to identify problems and challenges. Students will be tasked to work in groups for the research phase, and as individuals for the design application phase, according to the requirements of each stage of the studio. Research Phase observation & measurements with advanced digital technology, interviews with residents, and collection of maps) to acquire relevant knowledge to serve as the basis of design vision and strategies for all students. For this initial research phase, students will be grouped into 3 focal scales for their respective site investigation tasks. Refer below for the potential site survey inventory: 1. City scale—Infrastructural network (water, transport), land-use, urban density, history, demography etc. 2. Neighborhood scale—Digital mapping and measurements, typological studies, etc. 3. Site scale—Interview surveys, detail observations on materials and site furnishing, sectional studies etc. The knowledge / geo-data / maps collected during the site visit must be traceable or be based on vidual design developments at the later stage. Design Development Phase The last 7 weeks will be left to focus on design application, which will culminate in a convincing

small group projects after discussing with tutors through the course of the semester.

CITY SCALE - JAKARTA SITE VISIT Places/Sites Visited City Scale - Site Visit Strategy During our site visit to Jakarta, the city scale group ventured out further from just the landing site - in order to get a better understanding of other parts of Jakarta, especially the kampungs. The main aim was to study these different areas in relation to the waterways and its surrounding condition, which we can later study through a comparative study. This was done through a series of sections cut through these areas.

Map showing areas visited DAY 01 - Central Jakarta, Cikini & Manggarai DAY 03 - Angke River, Moonkevart Drain

DAY 02 - Waduk Pluit, Kampung Akuarium & Tongkol

Solid Waste Disposal Process Process 1: The residents usually just put the trash in front of the door, or hang on the trees or wall, waiting for wagons to collect them. Process 2: The trash collected by compant or government. The rack picker need to pay for the plastic and paper that collected from the garbage concentration center. Process 3: The garbage can be collected by company or government by trucks. Process 4: Some of the garbage can be recycled, while some can be treated in landfill.

SITE SCALE - GENERAL INTRODUCTION Site location

History of the area

In 1973, the then Governor Ali Sadikin moved the Ambon community a dutch-formed armies to Kedaung-Kali Angke area.Kampung Ambon is also known for its drug-dealing activities, and often seen police bust-up throughout the years. The rise of the drug-related problems started after the monetary crisis in 1998. In 1990, the village experienced population growth and began to be taxed. the village at that time was included in RT 13 and RT 14 and moved from Kelurahan Kapuk to Kelurahan Kedaung Kali Angke. Floods occurred 3 times, in 2002, 2007, and 2012. Evictions occurred in late 2014 and early 2015. in 2014 evictions of houses that intersect with Kali. and in 2015 demolished houses along Kali and normalized Kali. At the end of 2017, people submitted an objection letter, which contained a reduction in river widening and river-equivalent roads to be 10 meters and 5 meters. In 2020, The people of kampung applied for land certification, although it was rejected because the land was claimed by PT Sarana Jaya, but the land claim was incorrect. Then the people start to put forward a supply of clean water that was responded well by the national water supply company.

SITE SCALE - ROAD AND DRAINAGE Road Classification - Priamry Road Charcteristic The primary road is running from north to south along the Chengkareng River. The roads has two car lanes and narrow pedestrian spaces. People are gathering under the trees along the river. On the river bank, the night market selling clothes and toys is held on weekends Pros and Cons Crossing the road is dangerous because of the heavy traffic and motorbikes running fast. Hawkers and parking cars are one of the reasons of traffic jam.

60


SITE SCALE - ROAD AND DRAINAGE Road Classification - Secondary Road Charcteristic The secondary road is branched from the primary road. This is a two-lane road without a dividing strip. The street in the north side of our site is lined with some private shops.

Pros and Cons Crossing the road is dangerous because of the heavy traffic. Outsiders often snatch on the road.

61


SITE SCALE - ROAD AND DRAINAGE Road Classification - Secondary Road (Unpaved) Charcteristic The secondary road is running east-west along the Kali Aprun canal. The surface consists of some materials, including scattered garbages which affect the walkability. The width of the roads varies because of property line not defined.

Pros and Cons It is hard to walk on the mudy road after heavy rain. The unpaved condition restrains the road traffic. The unpaved condition allows residents to use the roads flexible.

SITE SCALE - LIFE AND LIVING Social Dynamics Interview

Interview Conclusions People along Kali Apuran feel more connected to the people on the other side of the Kali than the people who lives within the legal housing blocks. (similar background, informal settlements, economy, etc.) The relationship between the people from both sides of Kali Apuran started to deteriorate after the expansion of Kali Apuran. (defining new territory, administrative division, boundary) The people of the kampung are relatively independent, and do not really engaged in their daily activities. (lack of engagement with each other) The inspection road becomes a backyard for the people. (shows the importance and quality of the road as public space) The anxiety not only stems from the issue of eviction, but also some tensions between people of the kampung and a certain group.

LANDFILL RECOVERY ZHANG Bingyi

Jakarta, the capital of Indonesia, with a population of more than 10 million, faces a huge solid waste problem. The landfill is a serious urban problem in Jakarta, it will not only pollute the environment but also bring about people social, psychological and health problems. However, at present the Jakarta government only has preliminary measures for massive landfill (such as Bantar Gebang, which will be closed in 2021), but not for the informal scattered small landfills around Jakarta. Therefore, how to solve the problem of these scattered landfills will become a vital part of urban development. This program will start from the Kampung Kedung kali angke landfill, discussing how to recover of contaminated landfill site, making it becomes an urban park with ecological and recreational functions for kampung residents; and putting forward the new way of waste management, provide a new prototype of recovering over 200 landfills in Jakarta. The design will cover four design strategies, including garbage classification, water system recovery, vegetation recovery and soil recovery. Through some technologies, most garbage will be able to recycle in the landfill. Biodegradable can be used for composting; recyclable waste will become reusable materials, such as plastic tiles, recycled paper furniture, and construction waste will become structures. After covering with clay, nonrecyclable waste can reshape the terrain of landfill. Moreover, we can also achieve the water environment reconstruction and restoration of soil through the vegetation recovery and leachate treatment. Taking five years as a phase, the site will gradually transform into usable urban green space through three phases. PHASE I (0-5 YEAR): Over the first five-year period, recover Greenland landfill and open Kampung landfill to the public to deal with the waste. Technical supports such as Waste bank, Trashpresso, leachate treatment system technology will be established for further use. PHASE II (5-10 YEAR): For 5-10 year, the critical restoration areas will become the west side of Kampung Landfill. Greenland landfill will gradually become an eco-park to introduce some species inside. The mature soil contains the seeds of some native species can be used in other areas to help build soil structures. PHASE III (10-20 YEAR): The landfill thoroughly into urban green space available to the public-a eco-park after 10 to 20 years. Relevant waste management systems continue to be used (including recyclables and biodegradable waste can still be disposed of on-site). However, after the landfill is full, nonrecyclable waste will be transported to the intermediate treatment facility zone in north Jakarta. In short, waste reuse, garbage management, soil restoration and ecological restoration are combined to form a new method of landfill recovery, which can transform the rest of the scattered landfills in Jakarta. 81


JAKATA LANDFILL ANALYSIS

As one of the city's major problems, the issue of the landfills in Jakarta has inevitably and large impact on residents' lives and the environment.With the exception of Bantar Gebang (which is one of Indonesia's main landfills), Jakarta's landfills are small, scattered and mostly located in residential areas (especially in Kampung), making it inconvenient for the government to build effective solutions to manage them. Due to the low economic development, high housing density and planning unbalance reasons, west Jakarta district has the highest density in the whole city. The problems associated with this are that of Environmental, Health, and socio-economic Impacts.In order to improve the urban environment, how to solve the problem of garbage dump in Jakarta has become a problem to be discussed in this design.

FLOW CHART In the flow chart we can see some details about the design strategies. Garbage classification will include waste management and waste separation controlled by technological tools. Garbage will be roughly divided into biodegradable and non-biodegradable. In order to save the limited landfill space, each household will be encouraged to use bokashi tank to deal with the biodegradable waste. After composting process, the product will be sent to composting pond for soil recovery. Non-biodegradable waste will be send into waste bank and divided into recyclable waste and non-recyclable waste. Through some technologies like trashpresso, recyclable waste will become reusable materials, such as plastic tiles, recycled paper furniture, and construction waste will become structures. After covering with clay, non-recyclable waste can be used to reshape the terrain of landfill. Leachate is the main course of soil pollution and water pollution, and will also influence the vegetation growth. After collecting and purifying, leachate water will flow into drainage. In this process, the plant plays more of a role in treating leachate, which cannot be separated from the soil.

GARBAGESCAPE : Leveraging waste as a new medium that transforms Jakarta wasteland into public parks and urban developments Carissa Chin Qiwei The sheer magnitude of solid waste has always been a pressing environmental problem in many urban areas particularly in Jakarta. Despite the multitude of issues to minimise solid waste, the continuous flow of waste is still unceasing. These informal wastelands scattered in Jakarta naturally become the “malignant tumour” of the city environment. Taking the example of an existing informal wasteland located at Kampung Kedaung Kali Angke, the purpose of the Garbagescape leverages on the current and continuous waste problem. The intent is to change people’s perception of how wasteland can be transformed into while injecting programmes that engages people associating with the wasteland. This study aims to utilise the continuous flow of solid waste extracted from the existing site. Through the compression and stacking of solid waste bales, it creates and forms new topographic landform that acts as a structural foundation, opening up existing wasteland area for potential parkland and urban developments. The objective of this project is to alter people’s subjective opinion on waste landscape in transforming it into a new development plot in Jakarta. This project develops and constructs through a timeline approach : 1. Solid Waste Bales Compaction (Daily) Application of compacting residual waste assists in minimising land area and volume of waste produced. The compressed waste thus creates individual components known as solid waste bale. 2. Clearing of Existing Landfill (1 Year) Clearing of existing waste from the wasteland by transporting loose solid waste into waste compressor machines. Upon compression, these individual waste bales will be transported back to the wasteland site, representing as a structural element that can be stacked to create new landforms. 3. Fabricating topographic levels and landforms (5 – 10 Years) Stacking of solid waste bales act as structural foundation with exploration of new topographic landform. This process tackles the current issue of flooding in Jakarta by elevating the ground level to 5m in height as a flood protection barrier during storm events, creating potential land uses - parkland and urban developments. 4. Bioplastic film protection (1 Year) With the solid waste bales stack to a desired height, an impermeable bioplastic film protection is required to be capped around the waste bales that prevent any form of methane gases or leachate leakage from sipping though the waste bales into new surface grounds. Excessive toxic gases and leachate will be channelled through a gas well header and drainage pipe for proper means of disposal or recycling accordingly. 5. Potential parkland and urban developments for Jakarta wasteland (5-10 Years) Using the parkland and urban development as a starting point for future planned development for wastelands in Jakarta, the construction process defers depending on individual land use requirements. Specifically for parklands, varying of soil depth layer for new vegetation, including hardscapes (paving), will be constructed above the bioplastic film. Demarcation of urban developments will require piling foundations made before any stacking of solid waste bales with a pile cap that sets the ground foundation of any structural development.

REIMAGINING THE WASTE FLUX OF JAKARTA —RESILIENCE BEHIND THE WASTE HIERARCHY OF METROPOLIS

Zhou Zuyuan

Narrative: The project is located in West Jakarta. After assessing the current situation, the issues I summarized are as follows: -Insufficient waste collection frequency -Environmental issues caused by insufficient solid waste treatment -The mixture of waste from the source -Limited space for temporary waste storage points -incomplete solid waste treatment system in neighborhood site(mainly collection system) However, beyond the problems mentioned above, the site still has great potential. In the first place, 65% of the waste generated is organic. if organic waste is treated effectively, the amount of solid waste transferred to the landfill can be largely reduced. In addition, a large amount of underutilized green land in the neighborhood site. Most of them are now used as temporary storage for solid waste. If these green spaces are upgraded and used effectively, their potential will be greatly stimulated. The project with the vision to treat the waste from the source and tackle the waste problems from the source. Targeting the issues identified, the strategies are set up: -Waste separation from the source. -Utilize the underutilized green space for centralized composting facilities. -Neighborhood-based composting The above steps build a new garbage system comprised of several decentralized composting facilities as well as micro compost units scatted in the neighborhood. System: -Micro-level compost system(Little composting system contains waste separation, collection, composting and recycling, implement in the RT boundary) -Centralized composting facilities (Large composting system with 3 categories facilities: small size facility, medium-size facility, large size facility. The facilities are categorized according to the size of the facilities and the equipment they have.) Through a rough estimation, if we assume that the centralized system has 50 large facilities, medium-sized facilities are small size facilities. And in the micro-scale, each unit can cover one RT, the system can process 50% of total waste and 85% of organic waste. In this way, the amount of waste transferred to the landfill can be largely reduced, the status of solid waste will be effectively alleviated. The ongoing consequences of waste will continue to impact the life of the local people in ways that cannot be ameliorated or erased. The proposed system can be connected to several functions that may engage the public with landscapes of waste as a way to reveal the unconfined impacts of the waste system to improve the living environment and increase economic benefits. 111

The idea of composting is to reduce the CHALLENGES: waste quantity going to landfilling. In (1) Lack of community participation principle, the composting system comprises (2) Lack of supporting vehicles for 3R a centralized sorting system, and thereafter (reduce, reuse, recycle) composting of the organic waste. Remaining (3) Over capacity in Zero Waste part waste is either burned in the incinerator or transferred to the landfill.

4. Landfill

There is only one landfill in Jakarta. It is located in Bantar Gebang.

119

CHALLENGES: (1) It has exceeded its design capacity (2) Ordor, smoke and disease problems that caused by poor control of its operation.

What is Organic Waste? Organic waste takes up the most

129

Organic waste is any material that is biodegradable and comes from either a plant or an animal. Biodegradable waste is organic material that can be broken into carbon dioxide, methane or simple organic molecules. Examples of organic waste include green waste, food waste, food-soiled paper, non-hazardous wood waste, green waste, and landscape and pruning waste.


STRATEGIES TARGETED TO ISSUES AND POTENTIALS Strategy 1: Upgrade the greenland Tactic 1: Neighborhood-based composting, utilize the underutilized green space for centralized composting facilities.

Tactic 2: Combine composting facilities with other functions. E.g. parks, urban farm, which can form a sustainable cycle

130


Strategy 2: Upgrade the neiborhood Tactic 1: Waste separation from the source.

Solid waste generation parameters When acquiring a disposal site, the land area must be large enough to accommodate waste produced by 1000 people over period of at least 20-30 years. It has been documented that 1000 people would require 1 acre of land per annum (USEPA1971). This requirement is considered appropriate especially for developing countries where a higher proportion of waste generated is organic and easily be decomposed. 140

TREASURING WASTEWATER LANDSCAPE APPROACH ON DOMESTIC WASTEWATER TREATMENT AND THE FEASIBILITY OF LARGE-SCALE APPLICATIONS BASED ON THE CALCULATION

Lyu Jiawei Abstract: the increasingly severe problem of domestic wastewater pollution in Jakarta impact people’s life. This project intends to minimize the water pollution and the dependency on the urban water supply by using natural-based approaches. Moreover, providing a feasible method for largescale applications based on the mathematical calculation. Nearly 75 percent of the rivers in Jakarta are heavily polluted, of which the primary pollution source is domestic wastewater. Situated in Kedaung Kali Angke, the neighborhood, especially in the kampung, faces a severe problem of water insecurity due to the lack of public washing and toilet facility and some infrastructure related to the water supply, drainage, and sewage systems. Besides, the high cost of domestic water is hard to undertake by low-income workers. This project intends to minimize the water pollution and the dependency on the urban water supply by using natural-based approaches. The overall goal is to achieve the recycling of the wastewater and provide a feasible method for large- scale applications. Some wastewater parameters can be gotten like the area of required wetlands per capita, and the proportion of total green space needs to be used as wetlands in sites through calculation. The wastewater treatment system combines the anaerobic treatment and constructed wetlands, which consider the value of sewage purification and landscape characteristic. On the site scale, this design is taking one green space, in the middle of the Kedaung Kali Angke neighborhood, surrounded by the kampung and low-middle class residentials as an example to demonstrate this wastewater treatment system. Based on the calculation, 43% of the site green space needs to be used as wetlands for sewage treatment. There are three steps for sewage treatment. Firstly, the wastewater collected by the septic tank for settlement. Next, through the anaerobic pond and wetlands, the BOD (biochemical oxygen demand) and pathogens are removed mostly. Lastly, the purified water flows to the retention pond and holding tank for daily residential usage and some parts of purified water for agricultural irrigation and aquaculture meanwhile. As for the large scale application, the same sewage treatment system and mathematical calculations are used in conjunction with the 2030 planning. On the neighborhood scale, the green open space amount in the neighborhood is sufficient for domestic wastewater treatment through calculation. However, there is necessary to relocate it properly as an even distribution to cover the wastewater of the whole neighborhood residential area. On the city scale, through calculating the required wetlands area for sewage treatment in each district and the proportion of the wetlands area to total available green space, the feasibility and potential of the plan can be evaluated. From the data collected and calculated, at present, the required wetlands area accounts for 75% of the existing available parks in Jakarta, which is super high and low feasible. While in 2030, from the government planning, the greening rate targeted at 30% so that the green open space will increase significantly to 196 km². The required wetlands area for domestic wastewater treatment only accounts for 7% of the entire green open space. Therefore, the feasibility of this approach is much higher.

FROM RISK TO UTILIZATION ZHOU Xianfeng

Located in west Jakarta, Kampung Kedaung Kali Angke suffers from serious water pollution and scarcity of clean water. According to the investigation, the current stormwater system is a “one-way flow” system where stormwater runoff goes straight into canals. There is no system to clean, to harvest and to store for heavy storms, which results in water pollution and scarcity of clean water. This project aims to create a new ecological and sustainable stormwater “circular flow” system to filter, harvest and recycle rainwater in Kendaung Kali Angke. The proposal selects three open sites of different sizes focusing at the south-western corner of Kampung Kedaung Kali Angke for design interventions. The three sites are chosen from three perspectives: public, community and household, with different new stormwater treatment systems. Site 1: Public habitat (Total open space area: 9ha; Water storage capacity: 48000m3) A new wetland water treatment system is established in this area to increase diversity, improve water quality and provide wildlife habitats. The treatment wetland will perform its ecological function differently in each season. For dry season, wetlands store clean water filtered by complex systems for agricultural irrigation. For rainy season, wetlands provide space for stormwater runoff to gather and mitigate the effects of pollution. Site 2: Community mixed-use (Total open space area: 2ha; Water storage capacity: 6750m3) The rainwater collected from the roof of the factories is filtered through a complex stormwater treatment system to obtain clean water. Clean water is then pumped to the households and factories. In the meanwhile, stormwater runoff from the roads will be collected and diverted to a newly designed terraced raingarden, with the treated water being harvested for storage, irrigation and community-use. Site 3: Local household (Total open space area: 0.3ha; Water storage capacity: 840m3) A model of shared water shop is proposed in this site. The rainwater is collected from individual households through the water pipe, and it is filtered and treated in the shared water shop to access clean water for household-use. The small raingarden is used to clean and filter stormwater runoff from roads naturally. Additionally, a green corridor is built to connect the three sites and the surrounding communities so that people can interact with nature and enjoy recreation spaces. Depending on the size of the sites, the project can be applied to other parts of Kendaung Kali Angke as a model to address the issue of water pollution and provide clean water.

The strategy is to add drainage and pipes to better connect the water from the site to the river, and to design a reasonable flow direction according to the topography so that the water can flow naturally into the rain gardens and wetlands. The roof can be well used to collect rainwater and filter it to get clean water.

GREEN INFRASTRUCTURE FOR SRORMWATER MANAGEMENT Han Cong Frequent and severe flooding disaster has plagued Jakarta, Indonesia, for years. This site which called Kampung Keduang Kali Angke is a dense community of West Jakarta, the condition of a large number of impervious hardscape area resulted in that the infiltration rate is low, shabby unsound drainage system fail to discharge stormwater timely, these problems have made it had frequent flooding in the site. This project design is divided into three main strategies of green infrastructure management to delay and reduce the peak runoff to alleviate even solve flooding problems in the site. The first strategy is to redesign the drainage system and waterflow direction to collect and convey stormwater and discharge it to two main canals in the site, deducing the concentrated catchment area as the proposal water storage spaces. Than connect the existing drainage facilities along the streets with the water storage spaces to complete overall drainage system including primary drainage network, secondary drainage network, tertiary drainage network and new confluence point. The aim is to slow down the speed of waterflow discharged into the canals in the site. The second strategy is to design rainwater harvesting facilities, with rainwater collecting barrels to collect rainwater from rooftop and building surface, and use the rainwater filter barrels to filter it for water reuse, such as daily housing use and garden irrigation. And the rainwater harvesting facilities will be placed around the buildings within the radius of the catchment area. Lastely, the third strategy is to improve the water storage capacity by selecting the concentrated catchment area in the site according to the catchment analysis. Six different nodes will be designed as the potential water storage spaces that contain detailed bio-retention and detention facilities, such as community rain gardens and ecological detention ponds. The average area of these nodes is 466m2. The goal is to improve the storage capacity of the whole site through these shared pocket spaces. It also can be a pleasant feature that makes space for nature in an urban environment. Through these kinds of measurements, the aim is to create a proper site with thorough waterflow system and strong water capacity, so that it can make the site be flood-resistent, minimize the potential environmental impacts on stormwater runoff and provides a safe, resilient and comfortable living environment for local Kampung residents to promote social interaction among community members.

LIVE WITH WATER XIAO Xinyan

Jakarta has become increasingly vulnerable due to various conflicts, and recent heavy rains have even caused major disruptions. Therefore, this plan will assess that where are the most vulnerable points, and then relieve the pressure caused by the storm water through a series of landscape strategies, such securing green space for water absorption, and redesign evacuation system. The goal is allowing people to have safer choices when facing heavy rains or floods based on the truth that they have already gotten used to water.

REBIRTH RIVER _ LANDSCAPE DESIGN FOR RIVER RESTORATION BASED ON SEDIMENT COLLECTION AND MANAGING IN CANGKARENG DRAIN, JAKARTA BARAT FENG Zihan (Abstract: The flooding problem is an ongoing challenge in Jakarta. The design aims to solve the damage of sediment deposition to drainage function in the river and Create an adaptable river landscape to challenge irregular changes in water levels.) Since the start of the rainy season ten years ago, heavy rains in Jakarta have caused Many people became homeless and lost a lot of property. In recent years, 40 percent of the city to fall below sea level and the ground to keep sinking, due to geographical reasons and overexploitation of groundwater. All of these factors caused serious flooding. The design site, Cangkareng Drain, is an important link in the drainage facilities of Jakarta Barat. The surrounding area is very densely populated with residents and factories. In case of a flood, the damage will be devastating. In contrast to the government’s plan to widen the river, The design focuses on how to maintain the current channel width, using natural segregation to separate and remove sediment to achieve or exceed the carrying capacity of the widening channel plan. Firstly, I plan to divert the river into vacant land, meandering its flow path. Secondly, three sedimentation zones are set at the beginning of the designed channel. Regarding the sedimentation strategy of sediments, I did some simulation analysis. The result shows that there have some difference in flow rates on both sides of the curved channel, the clear water will be discharged from the outer channel which has faster water velocity, while the sediment will be deposited on the inner side and eventually deposited in the sediment pool. After a period of time, the sediment will be excavated on the inner side of the channel through manual intervention to reduce the problem of excessive sediment in the water. At the same time, the design also provides much needed public space, like fitness track and a museum for the use of the surrounding residents. The peninsula on the east side is designed to be work well together with flooding, and can partially replenish the shallow groundwater pumped out by people. It is known that the flooding issue in Jakarta has been affecting the society and environment in many ways and wouldn’t be completely solved in the near future. So I want to bring realistic and effective changes to the surroundings. And hopefully, it turns out to be sustainable.

More than 60 percent of Jakarta's residents depend on groundwater.This provides nearly two-thirds of the city’s water consumption, around 630 million cubic metres out of 1 billion m3/year.

12 centimetres of land is sinking every year in Jakarta, especially in northern parts of the city

NATURAL REVETMENT (DAMAGED):

Revetments, lacking protection from natural vegetation, are vulnerable to flooding and are a major source of sediment in downstream waterways

FARMING SPACE:

The lack of vegetation surrounding the natural and unreinforced channel, adjacent to the urban farmland system, is one of the reasons why the channel carries a lot of sediment during the rainy season

GARBAGE:

The ubiquitous garbage is carried downstream by the river, causing serious channel congestion.During periods of continuous rainfall, even severe flooding can occur

WATER POLLUTION:

Uncontrolled discharge of domestic sewage and industrial wastewater leads to eutrophication of water body and serious bed hardening. At present, the river carrying capacity is far lower than the designed level

FRESHWATER PUMP STATION:

Groundwater extracted by water pumps is the main source of urban domestic water

PUMP STATION:

Pumps arranged at the junction of inland and external rivers, which are responsible for the flood discharge function of inland rivers

REINFORCED CHANNEL:

The part of a river where Banks have been staked and reinforced by concrete

‘SINKING RIVER’:

The phenomenon that the water level of the main channel is higher than that of the inland river due to sediment deposition

HOME AGAIN ZHANG Bingqian

The site is located in the northwest of Jakarta, adjacent to Kali Canal. It is a kampung with a history of more than 60 years. The study found that the Kali River has been widened in 2015, resulting in the forced demolition of more than 300 families in the surrounding area and moved to the new residential community along Daan Mogot Street, nearly 7km away. Since many residents were unwilling to be demolished and did not want to move to new tall buildings, this issue intensified the conflict between the government and residents, leaving the remaining people still living by the Kali River without a sense of belonging. At the same time, in Jakarta’s 2030 plan, the road along the Kali River will be rebuilt and widened to become a secondary road, which means their home will face demolition as well. Therefore, it is inevitable for them to leave, and, Jakarta ’s violent resistance to relocation shows that new living conditions must be carefully considered. This project aims to provide a new living environment that can provide them with the sense of belonging. The new residence will enable them to adapt to the high-rise building and participate in social production, resulting them treating it as home rather than a temporary residence. Through field investigation, it is found that in kampung, people manage themselves through the RT and RW system, which is one of the reasons why they do not want to move. Secondly, their income comes from each other, only a few people are factory workers, more than 40% of the households are engaged in informal sales activities like street vendors. In addition, it has many outdoor activities. And Kali River as their public area has become part of their daily lives. This design will reconsider people ’s resettlement issues, making the site close to the river, and create different landscapes by introducing water from the river into residential and agricultural area. For better agricultural production, it is determined the most suitable cultivated land through sunshine analysis. And rivers introduced will provide the irrigation. In terms of living environment, the river will flow along each building to give people the familiar feeling of still living on the banks of the river. After satisfying self-sufficiency, they can obtain the sense of ownership and belonging again. At the same time, using farming activities as a catalyst can enhance sense of community, financial support, education, and branding.

BEYOND THE [ D E ] FENCE Deterring crime & Building communities around river Apuran Ekta Rakholiya

The project concern start from very personal experiences during site visit regarding theft and presence of rehab centers. Through further studies, it is found that Indonesia was formally a transit country for drugs, with much of its supply coming from Europe and other parts of Asia.1 But During the last five years, the domestic manufacture of crystal math has increased and is predicted that Indonesia will soon rival Europe as a provider for the world’s MDMA consumption.2 This indicates high presence of organized crime and certainly unfolding prominently in Jakarta. Looking further into the issue, it is found that usually young adults of age group 15 to 35 tend to engage in such organized crime. Most of them are either unemployed youth or migrant workers. Digging deeper into what motivates them to engage in the drug trade, three major factors are found : 1. Quick money making - hence helps to achieve financial independence, 2. Strong sense of Community and brotherhood - as they are often unwelcomed lone migrants in the Urban centers3 3. Addiction Hence, the project aim is to create systems that not only deter crime but make a gradual transition towards healthier transformation of the society. This is done through three major strategies largely borrowed from theory “Defensible spaces : Crime prevention through Environmental Design (CPTED) ”. This is achieved through three major strategies. 1. System Creations : To create cohesive society environment through job creation and social activities ; 2. Land use appropriation: To develop mix landuse and carefully re-laying road network to decrease the blind spots ; 3. On the ground : By transforming four different zones along the stretch of rive as per the immediate neighbourhood context. Drug trade is not just an urban problem but a “Landscape issue” as well. When the cities act as breeding ground for drug trade - in the backdrop, large mass of rural land is transformed to cultivate the plants used for these stimulants. I believe, the solution to this also lies in Urban landscapes reforms. The proposed design interventions make an attempt to act as a circuit breaker for smuggling issues in urban centers by creating better opportunities for social well being and financial independence of the people engaged in this risky industry. As the title suggests, the quest is to explore the idea of “Fence”; the notion of boundary and [de] fence i.e. the idea of “un-fencing” with the aim of “defence” against crime. Responding to the rapidly rising organized crime in Jakarta (especially the drug trade & narcotics addiction), this project aims to transform the four different zones around the portion of river Kali Apuran into a vibrant space that not only act as a programmatic defense against existing crime, but also provide opportunity to achieve social well-being and financial Independence, hence making a move towards a better tomorrow. On a broader spectrum, the proposal tend to touch upon defense against rising economic inequality and flood issues as well.

RECONFIGURATION OF RIVERSIDE COMMUNITY OPEN SPACE Written by CHENG Jing

Abstract By reconfiguring the land use to add and design green space, and increase the human activity function, to assume the role of communication and connection. Finally connecting that separates the density community. The river, North of Kali Angke, now is sandwiched between factories and residential areas. The hard revetment leads to poor water sensitivity with the monotonous landscape, lack of connection road, and vegetation. The land use around the riverbank, in addition to residential areas and factories, there are large areas of undeveloped land and landfills. The utilization rate of these areas is extremely low. Meanwhile, residential areas are densely populated and closed with a severe lack of open space. From what has been discussed above, there is insufficient space for daily activities and communication of the residents, resulting in the disconnection between the communities. Under Jakarta’s 2030 Masterplan, factories around the river will be turned into green trading and office areas. The closure of factories and the addition of residential areas have created new opportunities for riverbanks. But the government plan simply widens the river and increases the number of residential areas, leaving little to the landscape imagination. The main purpose of the project is to modify the government’s 2030 Masterplan with the existing land use to increase the riparian space and community open space. All this space will take on the role of community connection after landscape modification. The first step is to the reconfiguration of the riparian and community open space by analyzing the government plans and existing site conditions. For the riparian corridor, where there are already dense residential areas, the hard revetment shall be retained to maintain the existing residential space. In the middle section of the river, the two banks are undeveloped areas and factories, according to the runoff direction the south bank is selected as the segments suitable part of the river to widen and enrich the landscape. For the planned green space, increase the available green space by selecting the unused space in the new green office area. In summary, according to the revised planning, riparian expansion and the site condition increase the available green space. As the amount of green space increases, a green space system is formed, connecting the communities. Then, according to the new green space system, a landscape bridge is built on both sides of the riverside green space to connect the two sides and form a new pedestrian system. The road system and pedestrian system based on the new planned green space system also play the role of connecting the community. These green spaces will assume the responsibility for urban parks, playgrounds, and other activities of the residents. As the volume of residents’ activity and communication increases, the connectivity of the community will increase, ultimately eliminating the community disconnection.

REGENERATION OF THE VERNACULAR WATER LANDSCAPE TANAKA Mamiko

Each city or region has a historical process that is continuous from its inception to the present. By discovering the modern meaning and illuminating it, we can find clues to create unique values. Based on this belief, I proposed regeneration of the vernacular water landscape in Jakarta. After independence, Jakarta has been transforming for over 60 years. Through urban development, water has slowly evaporated from the mental map of the city’s residents. The industrial transformation and the change in lifestyle create a distance between people and water. At the same time, the change of land use and complex roads covered by asphalt weaken the presence of water from the topography. As a result, water culture has been altered to be a frustrating issue. Additionally, the current water management ways cause social and environmental problems while keeping the water away from humans. Therefore, based on the historical analysis, the interview, and the current land use, I proposed a floodable park and new types of agricultural communities with new water flow which would flow from west to north in the site. Both programs would create opportunities to appreciate water in life while managing flooding. In addition, in the intersection area, all people, including who belongs to different types of communities, could build an interactive relationship between themselves. That would enhance the sustainability and resilience on the site. From the satellite map of 2004, I extracted the previous paddy field pattern. The pattern color suggests the subtle height difference and possibility of flood. I used this pattern for the master plan to rekindle historical connection. In order, I designed the topography, water flow, zoning, and land use by using it. In short, expanding the project based on the historical analysis in each site, water would penetrate lifestyle and topography like the vein. That would create a more sustainable and resilient society in Jakarta .

317


ANALYSIS Issue and Background Nowadays, water culture has been altered to be a frustrating issue. People disconnect with water physically and mentally. However, due to frequency, people perceived floods in the delta areas as natural and normal. Primary industries such as agriculture and fisheries, were operated based on natural cycles including floods.

Issue Disconnection with Water 1. Negative images for water and rivers 2. Missing opportunities to appreciate water in life 3. Physical distances from river and oceans

Background Geographical Condition

318


ANALYSIS City Scale Analysis Historically, people used to be living with water in Jakarta. During the colonial era, the offensive approach towards nature and water brought from Dutch implemented.The Ciliwung River was diverted through a network of irrigation channels, spilling into the agriculture areas. After independence,

ANALYSIS Design Concept Through the agricultural process, all types of residents could appreciate nature and water. That would promote sustainability by local consumption of what is produced locally. In the urban floodable park, people could enjoy water activites and feel relaxed along the river. The park would serve as flood control eservoir. That would enhance the resilience on the site.

SPACES IN AND BETWEEN: A LANDSCAPE APPROACH FOR A COHESIVE MIXED CLASS COMMUNITY Shao Zhongran A settlement started to thrive in the northeast corner of nowadays Kedaung Kali Angke since the 1980s as the city of Jakarta sprawled. However, the community gradually split up as the public space encroached by the houses when the population boosted. The situation got even worsened after the government expanded the canal Kali Apuran in the year 2014. People feel disconnected with others living on the other side of the canal, and the tension between different classes is soaring. This proposal aims to provide an alternative for those settlements with familiar challenges through three strategies. The first imperative is inserting public spaces functionally into the community. According to the study of residents’ behavior pattern, people live in different parts of the site have their own preference for the public space. The ones living along the canal reckon on a re-connection with another side. Most lower-class families in the kampung have to share water and sanitary facilities with others while such space is currently disorganized, so they prefer more space with infrastructures among the kampungs. The higher-class families have larger private living space, in comparison, they show more interest in space with unique features like fitness, entertainment, and meditation. Tiny unutilized spaces are supposed to turn to venues to bring the community together through this strategy. In the second strategy, the existing road networks are renovated to improve connections between public spaces created. Partially uncovered drainage, undecorated front door area, lack of street greenery, and monotone paving styles make the existing road system a dull space for the residents. To transform the roads into an authentic zone for living and extend people’s range of movement, different types of roads are given their own identities by reforming the sections and adding road infrastructures. The paving varies in specific segments to indicate the public spaces surrounding. Also, the roads present motorists and drivers with a succession of both physical and visual restraints designed to encourage slow driving which also make it friendly to pedestrians. The third strategy is about reforming buildings and structures. The RW office and the mosque are the buildings tend to have the greatest impact upon the community in the village. Extending the function of the RW office into a community center and making a physical upgrade of both can help create hotspots in the village. What’s more, to boost the north-south connection in the village and highlight the two public buildings, a 1-storey high footbridge is proposed between them, with a roof garden and roof platform along the route. By creating the system of patches-network-hotspots, the proposal integrates the kampung village to a livable place as well as a cohesive community for people with different backgrounds in a regional context.

VIBRANT STREETS A Street-led Approach to an Improved Communal Fabric Poornima Bargotra In most kampungs, the street is a channel of movement, a communication space, a place of social and commercial encounters, and most of all, the only public space available. It has a symbolic value, holding an importance as a ceremonial space in the neighbourhood. They tend to be multifunctional and multi-layered instead of clearly zoned areas of uses and types, further resonating the vibrancy of these shared streets. The chosen site is located in Kedaung Kali Angke, a neighbourhood situated in the North West part of the dense city of Jakarta, Indonesia. With an area of 3.1ha and about 250 households, it comprises of diverse housing and road typologies. Through the adoption of multiple strategies, the aim of this project is to leverage the dynamic nature of the streets as natural conduits of the kampung, and reinvigorate the overall neighbourhood and kampung fabric through a “bang for the buck” approach. It is to look at streets as not just a physical entity for mobility and connectivity, but also as the familiar public realm where social, cultural and economic activities thrive efficiently. The first strategy is to redefine the streets by looking at how the residents tend to use the space. It is done by studying the current human activities and chalking out possible scenarios for new layers of active programming accordingly – by the use of various placemaking tools focusing on recreational, educational, economic and cultural necessities. These tools are designed with keeping the existing essence of multi-functionality in mind. This overall approach will also act as “social equalisers” which will bring households together, and further enable and provide space for activities while maintaining the integrity of the existing socio-economic conditions. The second strategy is to re-imagine new road typologies by proposing effective changes to the existing that can be prioritised according to the level of intervention and improvement, thus determining the cost factor. A mix of various approaches- comprising of road widening, tactical redefinition of road directionality and typology are set out to enhance the streetscape in terms of a planning standpoint. Road and green infrastructure tools are used – for example, introducing rain gardens, vegetated swales and permeable paving strategically. The third strategy is to formalise certain parts of the streets to create designated activity zones by studying the present typology of building uses, their locations and conditions. This approach will ensure that the parts of the streets selected for improvement are actually the ones that are likely to generate the highest impact on the optimisation of the land use - where the residents benefit not just socially, but also economically by now allowing space for commercial activities. By carrying out the above strategies and the various tools - the design envisions a street led approach to an improved communal fabric, while also trying to achieve the most impact out of the least invasive and costly interventions. The proposal can also become a possible model that can be adaptable to other similar sites.

Why streets? In most kampungs, the street is a channel of movement, a communication space, a place of social and commercial encounters, and most of all, the only public space available. It has a symbolic value, holding an importance as a ceremonial space in the neighbourhood. They tend to be multi-functional and multi-layered instead of clearly zoned areas of uses and types, further resonating the vibrancy of these shared streets.

ESSENCE OF MULTI-FUNCTIONALITY As the road along Cengkareng drain is now transformed into a fully pedestrianised zone, the design envisions to be multi-functional throughout the length of the street, with change in paving and placemaking playing a major role. Tools such as fishing pavilions, waterfront steps and picnic areas are proposed – paying homage to how people already use this space.

ARTIST’S IMPRESSION Bringing the elements together

By carrying out the design strategies, the design envisions to improve streets but still staying true to the basic essence of these streets - which comprises of the existing human activities. The artist’s impression here shows how some of these placemaking tools and elements come together - with a design derived from the people and designed for the people. 358

LIVABLE RIVERSPACE Lim Wenfa

Observation shows that activities conducted along the streetscape of Kedaung Kali Angke were disorganized. These disordered activities mismatch the way how public space should be designed and how people are using it. Fishing being one of those common activities along the streetscape was, in fact, a supplementary food source for the locals. Despite knowing that the rivers are polluted, some local continues to fish for food while some treated it as a form of leisure. According to research, water quality would gradually improve by 2026 due to the implementation of processing household wastewater before pumping into the rivers started in 2019. Therefore, it is highly encouraged to put this implementation into good use by concurrently reinvigorate the aquatic habitat of the river. This would benefit the supplementary food source and as well provides ecological values/hotspots to the region. As such, the project focuses on fishing as the design driver and aquatic habitat creation to inform the spatial design. The project also envisioned to enable human access to above the river’s space through integration with the process of aquatic habitat creation. Cengkareng river is chosen as the foundational river as most of the activities can be found clustering there. Elevated decks will be implemented as integration to the aquatic habitat to create elevated space for activities such as kiosk market, fishing, and other community events. The spatial designs will be driven by the creation of aquatic habitat in 3 intervention segments. In the first segment, to mimic a calm aquatic environment that will improve the fish population, half of the existing park will be merged with the river into a wetland park. This wetland park not only filters but also reduces the flow of water. The wetland park will also serve as an attraction to attract users with its openness and access to clean water to conduct a wider range of outdoor activities. In the second segment, the second half of the existing park will be integrated with the elevated kiosk market to provide seating space for users. The vertical supporting structure of the elevated decks will be attached with artificial aquatic habitat modules made from recycled materials to create a favorable environment for fishes to mingles and refuge. While this artificial habitat module primarily functions are to mimic the aquatic environment, they also trap solid wastes and can be easily removed and maintained. In the last segment, elevated fishing space will be extended to the mid-river to enhance fishing productivity. Fishing rod holders, benches, and wider spaces will be installed to enhances the fishing experience. Series of sponge vegetations will also be introduced to provide foods and hiding spots for fishes while distanced exposed water surfaces away from the riverbank to prevent unintended fishing activity. From this project, the idea of using the river’s space to create new spaces for activities and therefore reorganize an otherwise disordered streetscape can be applied to other similar contexts in Jakarta.

REFLECTIONS

378


We had the opportunity to visit Jakarta and work alongside UI students, which was a fruitful collaboration. Studying about the local community was eye opening and I was immediately intrigued by how people use the limited outdoor spaces (in the dense setting of the settlements) and make it their own. This led my project - to design for the community but by investigating impact out of the least invasive and costly interventions. I began to dive a lot into the socio-economic dynamics of the kampung and the multi-functional aspect of spaces. Throughout the process, I learnt to be self-critical, and focus on my rational my time management and prioritization. Excited to use the knowledge gained and see what the next studio has in store! Bargotra Poornima The studio offered me different perspectives on designing an adaptive landscape for Jakarta. Throughout this get to experience the living conditions within the kampung community, neighbourhood conditions as well as venturing out to other parts of Jakarta. This experience opens up opportunities where I can explore various possible design solutions which can better serve the people living in Jakarta. As my project focus on solid waste, I’ve gained waste production and am excited to apply the knowledge gained from this studio in the upcoming studios as well. Overall, this studio taught me to be analytical throughout the whole design process, to be bold in exploring new landscape design ideas and self-critical on my project work. Carissa Chin Qiwei This semester is an unforgettable one. First of all, I have never been to Jakarta, a big city with chaos and complexity. every day. The city is full of crises as well as opportunities. In addition, the studio course later became an online type because of the pandemic, and our project quickly entered the stage of personal design. This is a big challenge for everyone. We need to communicate the details of the plan with the teacher through video. I have to say it improves the ability to think alone. Finally, I tried large-scale urban shortcomings. I hope I can make progress next time.

Cheng Jing 379


This studio provided an opportunity to explore potentials of Landscape architecture to solve complex level city challenges. This was the first time for me to explore a complex city like Jakarta and confronting issues related to crime. While working on it, I realized that almost every city has those pockets and alleys where these negative activities breed and Landscape design strategy can really provide a solution for transition towards improving the neighbourhood. Though the final design outcome was greatly affected by COVID situation, I am extremely grateful for the guidance from Ervine and Kenya. I feel that this semester I learned a lot at the level of system thinking and social dynamics that shapes the spatial use in public places. Ekta Balubhai Rakholiya I really enjoy the process of the field trip, and the whole experience is very hard, interesting, and even unforgettable. The studio this semester enabled me to complete the design of a river from the perspective of the city-scale. It was a crazy design in a sense because I diverted the river. But it was for this reason that I was driven to study the nature of the river in-depth, to do various simulations to verify my conjecture. I believe that through this studio, I will have a deeper understanding of the laws of the natural river system than before, which also makes me pay more attention to the landscape benefits brought by the whole site design, and make better design decisions in future works.

Feng Zihan In the studio this semester, I decided to choose the topic of flooding management that I have never been exposed to, which was very complex and difficult for me. I had a lot of thinking, searched a lot of data and tried to make the runoff calculation. There were many mistakes and shortcomings in the final results, however, for myself, I harvest and achieved pretty much. This was the most complete design process I have ever made. In the further study, I will try to challenge other landscape issues and improve my design ability.

Han Cong 380


This semester had been a roller-coaster of emotional and stress which I have never experience in any of my pervious studios for the past 4years in NUS. The studio started with a comfortable pace of researching and site visiting and eventually expedited by the second half of the semester. Being naturally slow and lost in thought, I was stuck with my design thinking and couldn’t narrate and convince myself what exactly I wanted to do. Eventually I dropped a few initial explorations and things started geting clearer at last. I wished I could start on the final focus “river ecology” earlier so that I could strengthen my argument and really go deep into it. Nevertheless, I really enjoyed this semester as we get to experiences the kampung’s culture of Jakarta!

Lim Wenfa This semester, I learned a lot about design logical thinking and large-scale design principle. In a preliminary field trip, we went to Jakarta, where I gained the local situation, culture, city life and made new friends. What an unforgettable journey! During my design process, my design topic is wastewater, and I met some problems like professional theoretical knowledge, which involves engineering. It’s a big challenge for me. Fortunately, my tutors gave me a lot of useful suggestions and encouragement. They help me combing design logic and drawing revision. During this pandemic period, our normal face-to-face course cannot continue, but our tutors try their best to improve class quality. Thanks for their efforts! I hope I can study harder and learn more next semester. Lyu Jiawei I want to thank Ervine and Kenya for guiding and supporting me. I’m glad I made it through, although I could not work out the details. This project was a great opportunity for me to think about how to build an interactive relationship between humans and water deeply. I realized that referring to historical things is my fundamental design approach. Overall, through this semester, I have enhanced both my perspective and designing skills.

Mamiko Tanaka 381


This project has been an exciting one to work on, although the semester through the onset and prime of the pandemic was quite challenging. It helped me learn and experiment with the limitations of the scope of my profession. I liked that we were not given a specific site, and our instincts or interests were made to guide us to it. Jakarta was a very good site with lots to learn from and a web of complex challenges.The design process however, was interrupted due to current situation and changing restrictions. With a shift in work patterns and consultations i think i struggled to handle the changing ways of things working. Its been an unconventional journey full of anxiety and ambiguity, and we were lucky to have very understanding and supportive tutors to guide us through. Ruiee Vithal Dhuri This semester is quite special for us due to the COVID-19, but luckily we have made great progress. For me, the biggest challenge is keeping amending my design strategies to make them convincing and then defending my ideas of specific design proposals. This process was hard but turned out to be fruitful. It helps me have a better understanding of logical level in landscape design. I want to give thanks to Ervine and Kenya for putting much effort into their work under this situation. Also, I appreciate the company of our UI friends during our field research in Indonesia.

Shao Zhongran Compared with last studio designing for ecology, this semester I developed much more skills in designing the landscape infrastructure. Identifying the issues and developing the concept is a very resourceful experience, especially when lots of practical situations are considered. For the project itself, I find blue and green matrix can be large and complicated systems, and it requires hierarchical thinking to classify the major function systems inside the matrix, which will help me develop a more reasonable and convincing design idea. Other important knowledge I learnt is about landscape details. Landscape details can be abundant, so I should consider carefully before zooming into the most relative details.

Wang Haobo 382


Generally I really enjoyed this semester’s studio. I felt happy that my work could started with a macro methodology analysis then the design was developed step by step based on the analysis. The entire process helped to make my design become more reasonable. Apart from that, climate changes and flooding are the topics I always want to touch and explore, thus I’m satisfied I could do relevant design in real world and got the chance to do field trip in a totally unfamiliar context, which was challenging but interesting. This experience gave me a lot of surprise and more importantly, let me deal with conflicts in a complicated culture. Hopefully I could dig more in this field in the future.

Xiao Xinyan The studio is very close to the real project. We actually went to Jakarta. It is very useful to start from surveying the kampungs and end up with thoughtful designing. It is based on a very good understanding of the site. Among all stuff, the investigation with students in Jakarta has played a very good role in communication. We did it with them and we became good friends. My project is a sensitive topic, but our teachers do not evade it, but encourages me to follow the idea to design in depth. This is an unforgettable journey.

Zhang Bingqian This project gave me a chance to touch on issues like garbage dump that I had never touched before. This semester I learned how to think systematically about the design and completion of the whole project in terms of the timeline, how to integrate the landscape with technology tools, and how to sort the garbage and leachate. I am so grateful for the help and guidance Ervine and Kenya gave me.

Zhang Bingyi 383


I am quite grateful for the guidance from Ervine and Kenya. I think I have a better understanding of design after this Studio through the process of landing (Experience the complex ground conditions of Jakarta), grounding (Detailed analysis and experiential explorations), finding (Discover the potential areas), founding (Propose ways to restructure elements of the city). I learned more targeted analysis and derived my design based on analysis and observation.

Zhang Yifei During our field trip to Jakarta in this semester, I have experienced and learned a lot from this city. It was my first time to take an in-depth conversation to kampong residents, which was quite fresh to me. Meanwhile, it was an excellent opportunity to meet and study with UI students! Apart from that, the crime topic was a big challenge for me as well. Luckily, when I came across a lot of pitfalls during the whole process, thanks to Ervine and Kenya, gave many helpful suggestions to me and led me to the right direction finally. One pity thing is that on account of the epidemic situation, the face-to-face courses have reduced. However, I appreciated all the efforts we have made and happy with my improvement in logical thinking.

Zhong Yixin This semester’s studio gives me a brand new experience. The in-depth research in Jakarta made me feel the responsibility as a landscape architect and what I should do to change this situation. In this project, I mainly focus on stormwater management and how to bring new life experience to Jakarta through water. After the detailed analysis, the main issue is obtained and the new design strategy is established. Therefore, I am quite grateful for the guidance from Ervine and Kenya, so that my project can be presented step by step. Compared to last semester, I feel that I have made great progress, although there are still some areas that need to be improved.
