Rollback of ‘Banda Detachment’ Unexpected Historical Earthquakes in the Banda Islands

Adapted from article entitled “Earthquakes and tsunamis caused by low-angle normal faulting in the Banda Sea, Indonesia”

Although under the Banda Sea lies one of the most striking subduction, a group of scientist, including Irwan Meilano from Geodesy Research Group Faculty of Earth Science and Technology, Institut Teknologi Bandung, found that Banda earthquake and tsunami of 26 November 1852 caused by previously unidentified, low-angle normal fault system we name the ‘Banda Detachment’. This new study highlight two potential locations where the tsunami could have originated; the Banda detachment and submarine slump on the Weber Deep’s eastern side. Furthermore, the researchers model the two tsunamis and show that the tsunami waveforms generated by the submarine slump matches the historical records.

The paper on the results of this international research collaboration was published in Nature Geoscience under the title Earthquakes and tsunamis caused by low-angle normal faulting in the Banda Sea, Indonesia.

Indonesia is a country that is prone to earthquakes. Throughout 2022, the Indonesian Agency for Meteorological, Climatological and Geophysics recorded that there were 10,729 earthquakes. This natural disaster is related to the existence of an earthquake source that is formed due to plate interaction in Indonesia.

Located in the southeastern part of the Asian continent, Indonesia is at the confluence of three Earth’s largest plates, the Eurasian, Indo-Australian and Pacific plates. The movement of these three plates produces two subduction zones, Sunda and Banda subductions.

Meanwhile, in eastern Indonesia, under the Banda Sea lies one of the most striking subduction zones in the world with a 180˚ arc bend. In the Banda arc, the Eurasian plate is the upper plate on both the Indo-Australian plate in the south and the Pacific plate in the north. The Banda arc has a tight 300 km radius of curvature.

Although over the past decade the western part of the Sunda subduction has experienced several megathrust earthquakes, the subduction zones of the eastern Sunda, Banda arc, and eastern Indonesia have remained relatively calm over the last 150 years. What could have caused destructive earthquakes in the Banda Islands is a question that has puzzled scientists. Thanks to the discovery of a fault in the Banda Sea, researchers finally have the answer to this question.

“It would at first appear likely that large earthquakes and tsunamis that devastated the Banda Islands in the historical past, as well as the potential threat of future events, should be attributed to a megathrust along this Banda outer arc. However, since the Banda arc is a zone of arc–continent collision, it no longer features an oceanic trench and, therefore, no megathrust. Hence, it is imperative that the mechanism for destructive Banda Sea earthquake and tsunami generation is re-evaluated,” said the study.

Recently, there has been a proposal related to the configuration of the Banda subduction zone, which at the same time proved to explain the most intriguing physiographic features of the Banda Sea; Weber deep. “Here we propose an eastward subduction rollback that drives forearc extension,” says Jonathan M. Pownall, a researcher from the University of Hull, UK.

The rollback causes the lower crust and subcontinental lithospheric mantle rises to fill the gap opened above the rolling-back slab. This rollback also drives the extreme lithospheric extension which is accommodated by a major, previously unidentified, low-angle normal fault system we name the ‘Banda Detachment’.

Researchers consider whether historical accounts of destructive earthquakes in the Banda Sea can be explained by large but infrequent earthquakes on the Banda detachment and how these might generate tsunamis. They were focus on the earthquake of 26 November 1852 because it has the most extensive and detailed accounts of the devastated the Banda Islands and of the subsequent tsunami.

Source of the earthquake & tsunami

The 1852 earthquake generated its strongest felt intensity in the Banda Islands and intensity decreased northward at Ternate. Researchers wrote, “The only major fault identified so near the Banda Islands is the Banda detachment, and we therefore consider whether an earthquake on this fault, just east of the Banda Islands could give rise to the observed seismic intensities.”

Researchers consider an earthquake located along the surface of the Banda detachment that has a fault dip that can break during an earthquake. To produce rapid fall-off of the intensity observed from the 1852 earthquake, even the rupture in the Tanimbar Trench generates insufficient intensity. “nstead, the observed intensities favor a smaller earthquake near the Banda detachment.

The four tsunami observations of the 1852 event all clearly show that the source could not have been a megathrust event in the outer arc. The 1852 Banda sea tsunami has a particularly clear description of its arrival time relative to the earthquake. “This 20 minute delay between the occurrence of the earthquake and the arrival of the tsunami is an important constraint on the locus of tsunami generation.”

Therefore, researchers highlight two potential locations where the tsunami could have originated; the Banda detachment and submarine slump on the Weber Deep’s eastern side. Furthermore, the researchers model the two tsunamis and show that the tsunami waveforms generated by the submarine slump matches the historical records.

It is not certain that the mechanism behind the 1852 earthquake and tsunami also applies to other historical earthquakes in the Banda Sea. However, researchers suggest that the other historical major tsunamis that have affected the Banda Islands were caused by an earthquake-triggered submarine slump.

“Regardless of which fault caused the Banda Sea earthquakes of 1629–1852, it would be a mistake to assume the Banda detachment cannot rupture in a future earthquake simply because it lacks recorded seismicity,” the researchers conclude.*

Sound absorption of extracted pineapple-leaf fibres

A group of scientists including Iwan Prasetiyo, Ph.D. at Engineering Physics ITB wrote a report of the utilisation of fibres from the pineapple leaf (PALF) to be an alternative natural acoustic material. They fabricated samples from raw pineapple leaf fibres with different densities and thicknesses to observe their effects on the sound absorption characteristic.

Iwan Prasetiyo, Ph.D.

Measurement was conducted for the normal incidence sound absorption coefficient in an impedance tube based on ISO 10534-2. It reveals that the pineapple leaf fibres can achieve sound absorption coefficient of 0.9 on average above 1 kHz by controlling the densities of the fibres and/or by introducing the air gap behind the samples. It is also demonstrated that the sound absorption performance is similar to that of the commercial rock wool fibres and synthetic polyurethane foam.*

3D printing for bone tissue engineering

Materials, Volume 13, Issue 31 February 2020

ITB scientist, Dr. Arie Wibobo lead an international researchers in a study of 3D printing of polycaprolactone-polyaniline electroactive Scaffolds for bone tissue engineering. The researchers said, that electrostimulation and electroactive scaffolds can positively influence and guide cellular behaviour and thus has been garnering interest as a key tissue engineering strategy. The development of conducting polymers such as polyaniline enables the fabrication of conductive polymeric composite scaffolds. In this study, they report on the initial development of a polycaprolactone scaffold incorporating different weight loadings of a polyaniline microparticle filler.

The scaffolds are fabricated using screw-assisted extrusion-based 3D printing and are characterised for their morphological, mechanical, conductivity, and preliminary biological properties. The conductivity of the polycaprolactone scaffolds increases with the inclusion of polyaniline. The in vitro cytocompatibility of the scaffolds was assessed using human adipose-derived stem cells to determine cell viability and proliferation up to 21 days. A cytotoxicity threshold was reached at 1% wt. polyaniline loading. Scaffolds with 0.1% wt. polyaniline showed suitable compressive strength and conductivity for bone tissue engineering applications and demonstrated the highest cell viability at day 1 (88%) with cytocompatibility for up to 21 days in cell culture.*

The role of spatial planning in reducing exposure of global sea level rise

Spatial planning is expected to facilitate climate change adaptation by directing future spatial and infrastructure developments away from zones that are exposed to climate-related hazards. This study lead by ITB scientist, Dr. Djoko Santoso Abi Suroso attempts to confirm this understanding by mapping the effects of the various spatial plans on the northern coast of Java, Indonesia. First, the study maps the extent of coastal hazards for the baseline year of 2010 using a GIS-based inundation model.

Ocean and Coastal Management Volume

An overlay in GIS demonstrates the influence of spatial plans for the projection year of 2030. This allows for calculating the economic losses of the planned developments. The case study shows that the current provincial spatial plans of land use conversions along the northern coast of Java to continue to occur in the future. This could significantly decrease the regional capacity in dealing with the exposure to coastal inundation.

The spatial plans issued governments have not integrated measures against hazards related to global sea level rise. These findings provide a different perspective on the role of spatial planning for climate change adaptation than what is stated in the literature.*

Hypocenter Relocation along the Sunda Arc in Indonesia

The tectonics of the Sunda arc region is characterized by the junction of the Eurasian and IndoAustralian tectonic plates, causing complex dynamics to take place. High-seismicity rates in the Indonesian region occur due to the interaction between these tectonic plates. Prof. Dr. Andri Dian Nugraha, scientist at Global Geophysics Research Group of ITB lead a study of Hypocenter Relocation along the Sunda Arc in Indonesia, Using a 3D SeismicVelocity Model.

The availability of a denser network of seismometers after the earthquakes of Mw 9.1 in 2004 and Mw 8.6 in 2005 supports various seismic studies, one of which regards the precise relocation of the hypocenters. In this study, hypocenter relocation was performed using a teleseismic double-difference (DD) relocation method (teletomoDD) combining arrival times of P and S waves from stations at local, regional, and teleseismic distances.

Relocation results show a reduction in travel-time residuals compared with the initial locations. The relocation results better illuminate subducted slabs and active faults in the region such as the Mentawai back thrust and the outer rise in the subduction zone south of Java. Synthesis of the results provides further insight into seismogenesis in the region.*

Electrospun nanofiber from various source of expanded polystyrene (EPS) waste

This paper wrote by an international group of scientist, including Dr. Eng Muhammah Miftahul Munir (FMIPA ITB) reported on the fabrication of nanofibrous membranes from various sources of expanded polystyrene (EPS) waste using electrospinning technique and their application as air filter media. The filter membranes were made from four EPS waste sources, i.e. food packaging, EPS craft, instant noodle cup, and electronic packaging.

The properties of the membranes fabricated from those sources were compared to obtain the best EPS waste source for air filter application. To make the precursor solutions, those samples were dissolved in d-limonene:DMF . The solid EPS density, solution viscosity, and surface tension were measured. The fiber diameter and morphology of nanofibers were characterized by scanning electron microscopy (SEM) for each EPS variation.

The fabricated membrane properties (crystallinity, wettability, and mechanical strength) and filtration properties (pressure drop, PM2.5 filtration efficiency, and quality factor) were fully characterized and analyzed. Homogeneous fiber diameter with various morphologies (beaded, wrinkled, and smooth fiber) were obtained from all samples with hydrophobic to super-hydrophobic surface.

Also, the EPS solid density affected the solution viscosity with certain expression, which then affected the fabricated membrane packing density, porosity, and mechanical properties. Overall, the experimental results showed that all EPS nanofiber filters had great potential as an air filter media. The EPS filter made from food packaging waste with the solution concentration of 15 wt% exhibited the highest efficiency and quality factor .*

Exploring the relationships between motorcycle-based ride-sourcing, motorcycle taxis, and public transport in the Jakarta metropolitan area

Transportation Volume 47, Issue 5, Pages 2367 –2389, 1 October 2020

In the last decade, the emergence of ride-sourcing services has transformed personal trip behavior. In the context of Indonesia, ride-sourcing services have evolved into two modes of transport: motorcycle-based and car-based. The presence of such services has strongly impacted consumers’ choices of travel mode. However, the main question is whether the ride-sourcing service is a complement or a substitute for the existing public transport and conventional taxis.

Prawira F. Belgiawan Ph.D., scientist with Business Strategy and Marketing Interest Group ITB is co-author of a study to explore the relationships between motorcycle-based ride-sourcing, motorcycle taxis, and public transport in the Jakarta metropolitan area.

TIMES CITED 37 JOURNAL IMPACT FACTOR 5.192

The result shows that motorcycle-based ride-sourcing works as a complementary mode for the TransJakarta bus and Jakarta commuter train, but as a competitor with the motorcycle taxis. Contrarily, motorcycle taxis supported the existence of motorcycle-based ridesourcing. The study also found that individuals use motorcycle taxis as feeders to transit stops.*

Experimental analysis to design optimum phase type and salinity gradient of Alkaline Surfactant Polymer flooding at low saline reservoir

This paper presents the experimental analysis to find the optimum alkaline-surfactantpolymer (ASP) formula and the effects of salinity gradient suitable for oil reservoirs with low salinity formation water. It has been challenging to obtain high oil recovery when the reservoir salinity is lower than the injection salinity of ASP formulation.

A group of researchers, including Prof. Asep Kurnia Permadi, Ph.D. (Reservoir Engineering Research Group of ITB) carried out phase behavior tests for 28 experiments with 22 kinds of surfactant and subsequent coreflooding for the optimum formula with pre-designed salinity gradient profiling for preflush, ASP slug, and polymer drive. The optimum ASP formula from the phase behavior study, i.e., 0.5 wt% Linear alkylbenzene sulfonate (LAS), 2 wt% Diethylene glycol butyl ether (DGBE), and 1 wt% Na2CO3, results in the optimum salinity of 2.8 wt% NaCl with 10 cc/cc solubilization ratio, and the middle phase type III microemulsion occurs in the range of 2.5–3.4 wt% NaCl.

The oil recovery implementing this formula and negative salinity gradient, i.e. Winsor type II-III-I for coreflooding experiments are about 75.8% which is better than the other salinity gradients such as Winsor type I-II-I and I-III-I. Excluding high saline preflush, the salinity gradient consisted of Winsor type I-II-I and Winsor type I-III-I are able to recover the desirable amount of oil. The results could be applicable on designing the optimal ASP flooding at low salinity formation considering the formulation of surfactants and co-solvents, and the effects of salinity gradients.*

The largest obstacles in the utilization of municipal solid waste (MSW) as solid fuel in developing countries such as Indonesia are its high water content, irregular size and shape, and difficulty-to-sort due to the mix of plastic and organic waste. Based on literature study, wet torrefaction could be an appropriate pre-treatment process for mixed MSW because it requires no initial drying and mixed organic-plastic MSW can be processed without initial sorting.

In this research by a group of scientist including Dr. Eng. Pandji Prawisudha (Energy Conversion Research Group of ITB), experiments were conducted to investigate the effect of wet torrefaction on increasing the fuel properties of mixed MSW. Based on field survey, the composition of the analyzed sample was: leaf litter (34.67%), food waste (23.33%), vegetable waste (14.33%), fruit waste (11.00%), and non-recycled plastic (16.67%).

The experiments were conducted in a 2.5-L stirring reactor temperature variation (150, 175, 200 and 225 °C) with several holding times and solid loads. The result showed that wet torrefaction at a temperature of 200 °C with holding time of 30 min and solid load of 1:2.5 was the optimum condition, producing solid product with uniform physical shape, small particles and homogeneous particle size distribution, HHV of 33.01 MJ/kg and energy yield of 89%. The wet torrefaction process is not only suitable to convert the mixed MSW into renewable high energy density solid fuel, but it can also be used to produce separated organic product that can be used as solid fuel and plastic product that can be prepared for other treatments, such as pyrolysis to produce liquid fuel or recycling.*

Scaling mitigation in submerged vacuum membrane distillation and crystallization (VMDC) with periodic air-backwash

ITB Scientist Helen Julian, Ph.D. lead a new study of the applicability of periodic air-backwash to alleviate crystal fouling in submerged VMDC for inland brine water treatment was investigated in this study. Using polypropylene membrane and modelled inland brine solution at very high concentrations, the effect of air-backwash was evaluated against water production for operation parameters, such as backwash pressure, frequency and duration.

At the optimized operation parameters, the flux decline was successfully delayed, resulted in up to 150% and 25% increase in permeate productivity and crystal production, respectively. Incorporation of feed stirring and relaxation mode to submerged VMDC operation with air-backwash further increased the permeate productivity and crystal production by 230% and 32%.

Application of chemical cleaning once every 10 h of submerged VMDC operation using 2 wt% of citric acid and 50 wt% of ethanol resulted in sustained performance up to 6 cycles of operation for accelerated tests of highly concentrated feed.*

Technological solutions for long-term storage of partially used nuclear waste: A critical review

Nuclear power is an ideal option for sustainable energy sources from U-235 fission. However, this energy generates long-term radioactive waste such as partially used nuclear fuel (PUNF) during electricity production. This work reviews various technologies to provide viable, sustainable, and long-term solutions for the PUNF storage.

They include vitrification, partitioning and transmutation (P&T), pyro-processing, and deep geological repository (DGR). Their benefits and drawbacks are evaluated and compared based on previous studies. How to deal with the public perception of DGR and its impacts on the future of nuclear energy and the business opportunities of nuclear storage technology in the global market are discussed. A perspective of recycling nuclear waste into usable fuel is also elaborated.

Our literature survey of 160 published articles (1981–2021) showed that DGR is the most ideal solution for long-term storage of the PUNF, as it provides an ultimate destination in a deep underground that permanently isolates the waste from inhabitants and the environment. Although storing PUNF in a DGR maybe convenient and economical in the short-term, the waste must be stored in a retrievable form so that it can be recycled as a fuel. In the long-term, a complete recycling of used nuclear fuel is the best option. As technological solutions and sound radioactive waste management policy are important for the safe storage of PUNF, stakeholders in the nuclear industry should portray long-term radioactive waste management through viable, feasible, and permanent solutions to waste storage for the sake of public safety and the environment.*

Defining Rural Smartness and Its Impact: A Systematic Literature Review

The utilisation of information technology to facilitate “smartness” is considered as a promising approach to improve the rural economy. However, the explanation of how the adoption of smartness in rural areas can lead to an improvement in the citizen’s economic welfare is still lacking in current studies. This paper aims to formulate a theoretical model that explains the causal mechanism of smartness adoption in rural areas to contribute to the improvement of rural citizen’s economic welfare.

To achieve this, we conducted a systematic literature review based on three research questions resulting in 119 selected articles, which we used to formulate a theoretical model. The proposed model posits that rural smartness has a mediating effect on the citizen’s economic welfare through its positive impact on the competitiveness and innovativeness of rural business entities. Additionally, the proposed theoretical model highlights the necessity of adopting a smart service platform, representing the IT artefact for smartness.

We argue that the adoption of such a platform would have a significant moderating effect on the competitiveness and innovativeness of rural business entities. We also contribute a comprehensive set of candidate measures we extracted from the selected literature as operationalisation of the proposed model. In terms of contribution to practice, the proposed theoretical model can be used as the starting point to guide the diffusion of smartness in rural areas.*

A Tunable Peptide Delivery Platform Based On Biosilica

Rindia Maharani Putri, Ph.D.

ITB scientist, Rindia Maharani Putri, Ph.D utilizes biosilica shells from microalgae of diatom type as delivery platform for peptide drugs, such as insulin. Insulin is one of the most prominent examples of peptide-based drugs, commonly used in a therapy for diabetic patients.

Oral delivery of insulin is hindered by a relatively low bioavailability due to enzymatic proteolysis and low permeability across intestinal mucus barrier. A protecting shell, like biosilica, would help maintain cargo stability against degradation.

Compared to carbon-based delivery platforms, diatom biosilica is superior in terms of mechanical stability, monodispersity, and ease of modification. Silica-based oral delivery platforms are also preferred because they do not cause any change in textures, flavors, and tastes as a food additive. Compared to synthetic silica, diatom biosilica offers

an inherent nanoporous structure from a sustainable and inexpensive marine resource.

Despite the potential, there is no report on the exploration of diatom biosilica as a delivery system for peptide-based drugs. Hence, whether diatom biosilica could give a good performance as a biomaterial for peptide delivery system is currently unknown.

In light of this, Dr. Rindia’s research aim is to investigate the biosilica of C. striata diatom as a delivery platform for peptide drugs, using insulin as the model peptide. Experiments will be conducted in vitro and computationally or in silico to study the binding of insulin on the porous surface of biosilica and its subsequent release under physiological conditions.
