SITE INTRODUCTION Kampung Bangau-Bangau is mostly occupied by the Bajau communites whom have settled in that area. Many of the are refugees from the Philiphines that has to Malaysia illegally. The site is located in the Southern region of Sabah, located in the town of Semporna. Semporna have been identified as dirtiest town in Malaysia. The site of Kampung Bangau-Bangau is in danger as the site is exposed to many enviroemtal pollution that is mainly caused un-willingly by the Bajau communites living there. Without any establishment of waste maangement, all the waste are thrown into the ocean, polluting it.
BAJAU Originally from the Philiphines, the Bajau are known as the sea gypsies, as they would nomadically move and lives on seas in their house boat called lepa. They are known for their ability to hold on breath and free dive without any usage of equipment. They lives would revolve around fishing for their daily food. As the borders are established, the Bajau are stucked without anywhere to move and without being recognized as citizen, they are in deep expoitation by other people. Their need for money, forces them to turn the usage of overfishing.
P1 .MAPPING NARRATIVES . BOOKLET.
Story board The idea of the model map inspired from the coastal and ocean problems that occurs on the site of Semporna. Over the centuries to decade the costal and ocean has been affected because of human negligence. The map reprsents how the world would look like if the natural pyramid system have been rotated. The elevated represents ocean life, which now create wastes and dumps it to the land. The hour glass shows the time is ticking if we do not change the life now.

NARRATTIVE - INCARNATE
P2 .NARRATIVE.IDEATION.MATERIALISATION.
The scroll inspired from the centurie’s old indian scroll thats stores every action that occured in the region. This scrolld tells the story of a Bajau, nearing his death and reminscing the wonderfull life of Bajaus on the sea. As he dies, he then incarnate into various other enviroement enviroment before passing on to the other life. During this time he can see gradual changes of Bajau and enviroment that bothers him. The idea of incarnate also inspired from Bajau’s belief in Animism.
IDEATION
LONG BEFORE
The Bajau’s old lifestyle does not harm the enviroment, their method of fishing is more subtle and they would ony fish for the means of filling their stomach
CENTURIES AGO
The creation of gorverment and borders forces them to settle down in land areas. This indirectly changes their cultural lifestyle.
CURRENT STATE
The changes in thier lifestyle causes them to find better way to earn income, forcing them to turn to harmfull substances that would effect the enviroment.
FUTURE
The proposed solution would able to tacklethe current site problem while increasing their income value.

SITE ISSUES
BUILDING PROGRAMME
The Bajaus are not considered Malaysian by the goverment of Malaysia and are only catogarizedas refugees from Philiphines. Without any abilty to apply for citizenship they do not recieve the basic needs that other Malaysian citizen would recieve. Thus their main income would only comeeither illegal or over-fishing just to able to earn enough for monthly expendeture. THe second problem is their site condition, without any wate management provided, the areahas become literrring spot. With Semporna has been identified as the most dirtiest city in Malaysia. Both the human and solid waste are thrown into the ocean and polluting it.

DESIGN OBJECTIVES To create a COMPLEX where sorting facilty, HTL process room and commercial activties can be carried out within same vicinity. This reduces wastage of space while also acting as meeting point for the Bajau people living there.
Both the system able to reduce site pollution while also increasing Bajaus income value thus, enabling them to stop practising harmfull fishing.
SITE ANALYSIS WASTE COLLECTION
All the trashers are collected to a collection point before being arranged and transport to the main building. Each collection point caters for each region. The human waste are transfered to Semporna sewage center, where sludge are formed. The sludge are then transfered back to the building for the HTL process.
SITE ANALYSIS ACCESS
The location of proposed building located in center of main pedestrian bridge. The location has a high public exposure. The site location also allows for each vehicular access for both boat, truck and lorries. The lepa boat will be used to transfer the trashes.
SITE ANALYSIS RESIDENTIAL
Most of the Bajau houses located on the ocean shores. The stilt houses are made from timber or wooden materials. Most of the stilt houses and bridges are worn out.
SITE ANALYSIS COMMUNITY SPACE
The site has a small amount of shop that mainly operates in a small or stall business style. They would just sell daily essential goods. Other moods business are the boat workshop. Goverment primary school are provided. Small community center is also present.
SITE ANALYSIS COLLECTION CENTER REGIONS SITE ANALYSIS INTERVIEW (BORNEO KOMRAD) I have also conducted interview with on of the NGO’s working on site of Kampung Bangau- Bangau. His name is Mukmin Nantang and he is a volunteer teacher on the site with few others. His quoted words are used as evidence for my selection of the problem and the proposed solution towards it.
As the site is big, regional collection center would collect trashes from their region. Non-recyclable and recyclable materials are separated on each respective centers.
SITE ANALYSIS MICRO ANALYSIS
“
“Their monthly income is around RM 200- 900” “Their monthly expenditure is around RM 600-1200.” “The most that can be seen are the plastic and they are usually seen around the beaches and around the mangrove forest” “They do not manage their thrashes well, they would just dump it into the ocean because not proper system are provided.”
The proposed location is located on the main bridge because it is located further away from any other residential building. The mechanical used in the sorting facilty and the HTL process room would create noise and also heat. The site also would recieve good natural ventilation.
”
FINIDNGS / RESEARCH RECYCLABLE MATERIALS
FINIDNGS / RESEARCH PROBABLE SPONSOR FOR the HTL PRoccesing room
Not every materials are recyclable, thus by teaching the Bajau this would allow them to separate the non-recyclable with the recyclable. This will be done at the regional collection center. While all the nonrecyclable materials are then transported out to the dumping grounds.
Findings few sponsor to sponsor in terms of education and financially is important, as certain machinaries are expensive and hard to be used. Thus certain sponsor have been identified to help in proposals.
Yayasan Petronas have been targeted as good sponsorship company as, they are known to provide charities for needy family for years. Petronas can also be perfect candidate to sponsor becasue they can provide the financial and education support to manuver the HTL process. Thus the space would be directly under the managament of Petronas for future research.
FINIDNGS / RESEARCH HTL PROCESS
FINIDNGS / RESEARCH PROBABLE SPONSOR of machinery for the sorting facilty
Hydrothermal Liquefidication (HTL) is process where waste that goes to pressure and heat to be converted into biofuel. It follows the same concept of how the earth converts waste into biofuel overtime. This by-product from this process are not flammable nor reactive thus making it save to be produced on site.
World Wild Life is a NGOs that focuses on the natural enviroment and community people. WWF has had history working and helping the Bajau around the Coral Traingle Area. The idea of creating a proposed building where it cleans the ocean would entice WWF to sponsor few machinery for the proposed building.
SPACE AND CIRULATION PLANNING
DESIGN STRATEGIES
Early development space is to create an area where all the space functions as individual space but without being separated from the outside activties. Thus the idea of a structual framing where every view of the space can be identified from any location. This creates a sense of community.
STRUCTURAL/FORM SYSTEM STUDY The structure allows for no usage of columns in between space which allows for open space plan. The building form also allows for heat and noise to disperse out.
The idea of this structural form represents the close packed of Bajau houses that creates the sense of community.
The main space that consists of Sorting facilty and HTL process are elevated above ground. This is so that, processed materials can easily be transfered down. The community space located above the main bridge, with the main bridge now allows for boat parking area. Ramp are connected to each floor depicting story and event that changes along each floor.
FORM DEVELOPEMENT
Solid block on proposed site
A solid block of cube was first form on the porposed site.
Access to the proposed building is through the main bridge. Allow for direct transit. Fire safety staircases are placed on each side to comply with fire requirements and easy access out and into the building
Void
Void is created. It creates space segreation and creates privacy
The building are the opened up to allow natural ventilaion and views The design also is to create a sense of community with no blockage of wall.
Location of the main space. Away from any other space that would be affected from the sound and heat. Easy transit out of byproduct.
The building are elevated to different height to create space privacy. To separate
Ramp are used as direct acces to the space within the building. It allows for easy transportation of goods to other space that does not require the usage of goods lift.

Further income can be achived with selling of recycled materials. While also cleans the ocean.
GATHERING POINT Where public, Bajau communities, working class meet together
CAFES AND RESTAURENTS As the bi-product are sold. The Bajau has better income to open their own cafes. Reducing the dependence on ocean enviroment.
5 COMMUNITY CENTER
6
The spaces on the left show where all the storage space are located. This storage spaces equalls income value as they can later be selled to gain profit. This also reduces the waste and trashs that accumulated on site.
As the community have higher income, they have more spare time for themselves. Creating more closed pack communites.
The spaces on the right show the reaction from gaining all the profit. The Bajau can now self-sustain that they could leave activites that would harm the ocean enviroment.

Area located near the openings has better airflow, therefore the area has lower temperature. While the central region get hotter as the wind unable to reach inner regions.
The openings allows for continous wind flow, that would effecienly increase cross ventialtion.
Usage of machinery in this region, also increases the temperature in the central areas. Its an opened opening with only wire gauze covering it.
The higher air-flow from the right openings pushes out hot air presence in the space.
Purpose: Purpose of this mechanical fan is to further facilitate the natural ventilation. The selected modal, cools down the space while increasing the effeciency of cross-ventilation
