Published: June 2021

Abstract
The Jakarta groundwater basin is constructed by tertiary, Pleistocene and resent rock consisting of sedimentary rocks, volcanic activities and alluvial. There are three very potential aquifer layers found in this basin i.e. shallow aquifers, upper confined aquifers, and lower confined aquifers bounded by several aquitard. High economic and development activities cause high vulnerability to polluted aquifers such as nutrients. Previous research mentioned the presence of nutrients in groundwater in urban areas can be caused by high anthropogenic activity. Nutrient contamination in groundwater can be a threat to ecosystems in coastal areas. The purpose of this paper is to understand nutrient transport patterns through groundwater hydrogeology systems in the Jakarta groundwater basin, so that the amount of groundwater contribution to the nutrient flux in the Jakarta bay can be estimated. To get the transport nutrient model, QSWATMOD tools in QGIS Software were used. The parameters used in transport nutrient modeling are the definition of subbasins in the SWAT hydrology model, Hydrological Response Unit (HRU), rivers, aquifer thickness, hydraulic conductivity, specific storage, specific yield, hydraulic head, porosity, longitudinal dispersivity, and denitrification rate constant. The sub-basins and river constraints used are the Ciliwung Watersheds fill the Jakarta groundwater basin. The result show Leached Nitrate at the study area was 42 kg/ha and total P loss were 5 kg/ha. However the higher groundwater recharge in the study area increased the risk of groundwater contaminant by nitrate.
Unravelling the pathway of macro and micro debris in the beach of uninhabited Semak Daun reef platform, Kepulauan Seribu

Abstract
Marine debris is ubiquitous and possess threats to marine organism and ecosystem. Due to its small size, micro debris can be consumed by marine organism. Ingestion of micro debris including microplastic can be detrimental. We investigate the pathway of macro and micro debris in the beach of Semak Daun, an uninhabited island in the Kepulauan Seribu which is famous for tourism. Macro debris sampling was done in the intertidal and subtidal beach, covering both northern and southern part. Micro debris sampling was conducted in the northern part of intertidal beach, three replicate samples were gathered within a radius of 5 m. The most abundance macro debris in the study area were plastic cup and plastic wrap, most of them were found sinking in the seawater. Foam, potentially originated from camping mattress or footwear, composed as the most abundance micro debris. Beach sediment were seen filling the void on the foam surface, a feature that can facilitate density modification which generates foam to sink on the seafloor. Our finding implies that uninhabited island can be polluted by marine debris due to mismanaged waste from tourism. The fact that a large number of marine litters were found in subtidal beach should raise our concern, as hydrodynamic process potentially transported and accumulated them in lagoon or reef front. Further research is crucial to investigate the pathways of marine debris in the reef environment, the result is expected to provide knowledge on better waste management.

Published: June 2021

Abstract
The declining quality of surface water resources leads to groundwater exploitation as a source of fresh water. The developing urban environment also increases the need for groundwater resources as freshwater. Each rock in a geology formation has a different ability to transmit groundwater. There are various ways to obtain parameters of hydraulic conductivity and groundwater transmissivity. The commod method were time and cost consuming. The new method for estimation of geohydraulic parameter were needed. This paper aims to estimate geohydraulic parameters using different techniques and approaches and compares them. Geohydraulic parameter based on Heigold approach show the value of transmissivity at the study area in the range of 22.8 - 1307 m2/day. Geohydraulic parameter based on Niwas and Singhal approach indicate the value of transmissivity at the study area in the range of 32.55 - 30245 m2/day.. The highest hydraulic conductivity and transmissivity values were in the southern and northern parts of the study area. In general, the estimation approach was able to estimate the geohydraulic value at the study area.

Published: June 2021

Abstract
Land conditions in the upper Citarum watershed have been increasingly critical in recent times, causing various problems, especially the high erosion that is considered one of the factors causing river sedimentation and triggering flood. Agroforestry has provided a positive impact on the soil conservation aspect. The dense and critical land in the Upper Citarum watershed has been converted to agroforestry in the last decades. This study aims to estimate the rate of soil erosion of different agroforestry land systems at the Upper Citarum watershed using the MUSLE model. The results show that the surface runoff and soil erosion in forest-based agroforestry systems with intercropping patterns is lower than in farm-based agroforestry.

Published: June 2021

Abstract
Simeulue Island is located in the forearc west of Sumatra Island. Due to the subduction process of the Indo-Australian plate beneath the Eurasian plate, high seismic activities occur around Simeulue Island. A temporary seismic network was installed on the island from December 2005 to March 2006 to study seismicity around this region. From previous studies, using ambient vibration records, it is possible to extract a site amplification of sediment on the top of a bedrock, which gives influence on the seismic signal. In addition to the site amplification, it is also possible to determine information of the velocity model on the shallow subsurface. In this preliminary study, we applied horizontal to vertical time frequency analysis (HVTFA) to obtain ellipticity from recorded vibration from three temporary seismometers. An inversion was applied to the computed Rayleigh ellipticity to obtain the best fit subsurface velocity model.

Published: June 2021

Abstract
Elucidating the Baribis active fault in the central part of West Java is challenging due to the lack of physiography appearance. A gravity survey was conducted on 838 stations around the North of Bandung to Subang region to identify its buried spatial fault continuity. Regular processing routine reduced the observed gravity acceleration to generate the refined Bouguer anomaly map. Additionally, edge detection techniques (e.g., tilt derivative and analytic signal) were analyzed to delineate the proven fault emergence from the published active fault database and surface geological map. The results depict that the Baribis fault was continued to the Subang region and enhanced clearly by applying analytic signal attributes. Thereby, the Baribis fault continuity is better interpreted on the analytic signal anomaly map, whereas the tilt derivative technique explains the factor of unclear surficial discontinuity of Baribis fault on the zone.
An initial experiment with the continuous gravity monitoring using the gPhone 145 to support hydrology and earthquake studies
Authors: Handayani L. , Sudrajat Y. 
Published: June 2021

Abstract
Continuous gravity monitoring as geodetic instruments for tidal variation recording has been proving its availability for more applications. The original purpose was to monitor the changes in gravity at one local, which could be correlated to the hydrological variation and geothermal reservoir changes. Most recently explored was its relation to the events of earthquakes. We have been installing the gPhone 145 since 2016 at LIPI Campus in Bandung as a preliminary observation of the instrument. In four years of installation, the gPhone has recorded the relative gravity intermittently, interrupted only by technical problems. Temperature and pressure records indicate the instrument functions properly. However, uneven recording prevented hydrological study, in which we expected to see some changes of the gravity through the years. For earthquakes’ precursor studies, additional samples of events and time-associated gravity anomalies might give more assuring results.

Abstract
The Sumatran offshore region is known as an active seismogenic zone. Consequently, there were many records of great events that caused a big catastrophe, such as the 2004 Sumatra-Andaman earthquake. In order to investigate the geometry and nature of the earthquake ruptures and structures, we utilize the bathymetry and Multi-Channel Seismic (MCS) profiles from the SO-198 research project in 2008 (R/V Sonne) and KH-10-5 research project in 2010 (R/V Hakuho-Maru). We find that the area along the Sunda Trench to the fore-arc high in the northwestern Sumatra are characterized by parallel anticlinal ridges with distinctive vergence regimes. These vergence regimes classified as seaward, mix and landward vergence system. Our data interpretation recognized structures such as Main thrust, Lower thrust, Middle thrust, Upper thrust, piggy-back basin and West Andaman Fault within this region. Our conclusion suggest that the anticlinal seaward and landward vergence are considered as the product of recent deformation rupture. The co-seismic slip from the past earthquake ruptures tends that it was occurred from the deeper part in the entire northwestern of Sumatra fore-arc.

Abstract
Mine activities in the open-pit method are usually dominated by digging-loading-hauling. This hauling road is the infrastructures that is highly essential in mine area and serve as main linkage some locations. Design of the road requires careful attend in avoidance of failure in construction and disruption in production activities. Field investigations such as insitu CBR testing and laboratory testing (Proctor Modified and CBR laboratory) were chosen to determine the geotechnical parameters of soils that needed in the design of hauling road. The average value of the laboratory CBR testing at 0.1 inch penetration was 16%. The modified type of proctor test comprise some parameters such as the average value of the maximum dry density was 1.64 gr/cm3; the maximum wet density was 1.97 gr/cm3; the average value of dry unit weight was 16.07 kN/m3; saturated unit weight was 19.30 kN/m3; optimum moisture content was 20.2%. The average value of insitu CBR testing at 0.1 inch penetration was 19%. The average load of tire pressures on the front and rear wheels is 7000 lbs. The ability of road to carry the load should have the bearing capacity > 20800 psf = 144.44 psi = 20.95 kPa. The thickness of each pavement layer is as follows: 17 inches of sub grade layer; 2 inches of sub-base course layer; 15 inches of base course layer; 5 inches of surface course layer.

Abstract
Coal ash is a material from coal combustion and recently is an economical source for the extraction of valuable elements such as rare earth elements and Yttrium (REY) and base metals. Eight coal samples from Senakin coal field were collected to identify their mineralogy composition in raw coal and coal ash. The ashing was carried out on coal samples at temperature 1000°C for 1 hour. The coal and coal ash samples were made polish section to identify the organic and inorganic constituents. In addition, the minerals in coal sampel were identified by X-ray diffraction analysis. From this study, organic constituent consist of vitrinite (60 – 71%), liptinite (22 – 33%) and inertinite (5 – 9%). Minerals found in coal are kaolinite (25,78 – 46,90), pyrite (24,16 – 38,38%), quartz (6,07 – 12,80%), gypsum (4,81 – 10,34%), chlorite (2,56 – 8,40%), jarosite (0,72 – 4,63%), hematite (0,96 – 3,81%), calcite (0,37 – 5,07%), Mg-calcite (0,11 – 3,20%), dolomite (1,35 – 3,55%), and siderite (1,22%). Coal ash is composed of organic and inorganic components. Organic components found is unburned coal (3,09 – 8,55%) derived from maceral which does not burn out, mainly inertinite group. While inorganic components found are fe-oxide mineral (40,36 – 54,55%), quartz (24,55 – 33,64%), mullite (5,09 – 7,82%), cenosphere (7,45 – 10,91%), pleiosphere (1,64 – 2,36%), pyrite (0,18 – 1,27%), and spinel (0,18 – 1,09%). Fe-oxide minerals are interpreted derived from Fe-bearing minerals in coal samples such as pyrite, hematite, and siderite. Kaolinite which is the dominant mineral in coal is transformed to cenosphere, pleiosphere, and mullite. Quartz in coal ash derived from quartz in the coal sample because ashing temperature does not exceed the melting temperature of quartz. Characterization of the coal ash component can be used as a reference for the extraction method of valuable elements.
Women and Social Sustainability: A Critical Parametric Evaluation of Urban Settings in Developing Countries
Authors: Yadav Asmita , Kumari Rashmi 
Published: June 2021

Abstract
Attainment of social sustainability became a focused agenda ever since the United Nations general assembly (UNGA) adopted SDG goals in 2015. Sustainability is an umbrella concept cutting across public, commercial, and environmental domains. However, the idea is still perceived and seen as very narrow and synonymous with eco-friendly only. Gender issues still remain ignored in both academic and applied research as a contributing parameter towards sustainable development. Barely any field of knowledge is working on those concerns. Women empowerment and counterbalancing rigid patriarchy are still perceived as a research area for social sciences rather than holistic understanding and application by other academic disciplines. Urban planning needs a multidisciplinary approach that integrates with various other domains. It demands an amalgamation of analysis and application from multiple perspectives and considerations. The critical phase for urban planning, especially women’s sensitivity, is mostly missing in developing nations like India. Despite women having a more generous and vital contribution toward a city’s growth in cultural and economic terms, they have been under constant subjugation of brutality and suppression. Thus, the city planning process is perpetuating gender disparity, if not promoting explicitly. This study starts with a hypothesis, i.e., “ill-conceived urban planning has a huge stake in prevailing urban crime against women.” The research would later analyze and determine the flaws and loopholes in the planning process, which are in practice. Such lacks in the framework will create cities/urban areas that pose a severe safety and security threat. So, the gender layer during those planning processes may increase gender sensitivity toward women. The research will also explore essential concepts such as universal design and crime reduction through environmental design (CPTED) to assess women-friendly cities’ applicability. Thus, this approach can help deduce planning strategies to create inclusive cities, including urban social sustainability.

Published: June 2021

Abstract
Wood is generally used as a source of energy for cooking in rural and semi-urban areas of India. Approximately 216 million tons per year of wood is consumed in the cooking of which 9.731 million tons per year is used in Gujarat. The use of wood causes deforestation and increases indoor pollution. To reduce this, solar energy can be used as an alternate source of energy for cooking. The current research aims to present the findings of two weeks of experiments in the Indian (Gujarat) climate with the novel solar cooker. The cooker was build using a parabolic dish collector (85 % reflectivity) with a supporting structure and adjustable mechanism, a receiver (heat exchanger) and a cooking burner with a pot. The experimental result shows that the maximum temperature available at the receiver is 110°C with 560.7 W/m2 of average solar irradiation, justifying solar cooking as a viable alternative source of energy for cooking in Gujarat and India.
