<![CDATA[The rapid urban expansion of the Greater Jakarta metropolitan area has placed significant pressure on public service provision in its satellite cities, including South Tangerang City. Despite recording the highest Human Development Index (HDI = 84.16) among the Bodetabek region, access to public facilities remains unequal across sub- districts. This study aims to analyse the spatial equity of public facility distribution in South Tangerang City across three sectors: education (primary, junior, and senior high schools), health (public health centres and hospitals), and public transportation (bus stops and train/commuter rail stations). Spatial analysis was performed using two complementary methods: Nearest Neighbour Analysis (NNA), which computes the Nearest Neighbour Index (NNI) — a dimensionless ratio comparing observed mean inter-facility distances to those expected under a random spatial distribution — to identify whether facility point patterns are clustered (NNI < 0.7), random (0.8–1.4), or dispersed (NNI > 1.5); and network-based Service Area Analysis, which delineates reachable zones from each facility via the actual road network. Data were sourced from OpenStreetMap (OSM) and the Indonesian National Topographic Map (RBI BIG 2022), processed in QGIS using the QuickOSM plugin and QNEAT3 network analysis toolbox. Results indicate that most facilities exhibit a clustered distribution pattern, particularly bus stops (NNI = 0.298), schools (NNI = 0.603), and hospitals (NNI = 0.603). Service area analysis revealed significant blank spots primarily in health and transportation sectors: four sub-districts — Pakulonan, Pondok Cabe Udik, Keranggan, and Pakujaya — fall outside the ideal community health centers/clinics service radius, while seven sub-districts are located more than 5 km from the nearest train/commuter rail station. Education and hospital coverage generally meets service standards at the sub-district scale. These findings confirm that public facility distribution in South Tangerang City has not fully satisfied the principle of spatial equity, and that access to public services continues to be determined largely by place of residence.]]>

<![CDATA[Effective waste management at university campuses requires systematic evaluation of containment systems and collection operations. This study assessed waste generation, containment conditions, and collection practices at Dramaga Campus, IPB University, Indonesia. Waste sampling was conducted over eight days at 40 collection points across academic, dormitory, general facility, and canteen zones, following SNI 19-3964-1994. Waste at Taman Semangat Integrated Waste Management Facility (TPST) was sampled on two additional days. Total daily waste generation averaged 3.25 tonnes, yielding a per capita generation rate of 0.13 kg/person/day, which is below the global average for higher education institutions (0.19–0.21 kg/person/day). Organic waste dominated all source zones (39–66% by weight), followed by plastic (17–44%) and paper (10–25%). Waste containment relied on two container types—concrete and plastic—classified as communal containers. Evaluation against SNI 19-2454:2002 revealed multiple non-conformities: absence of waste segregation at source, inconsistent container placement, and underutilized containers at peripheral sites. Waste collection follows a Stationary Container System operated by two colour-coded trucks across two daily shifts. The existing fleet of two active trucks requires a total of five trips per day to remove all generated waste, but the current schedule is insufficient to fully serve all sites daily. Recommendations include spatial redistribution of containers, enforcement of source segregation, and expansion of collection capacity.]]>

<![CDATA[The redevelopment of the slum area in Community Unit CU (Rukun Warga/RW) 07 Babakan Raya, Dramaga District, is a strategic step to reduce slum conditions while improving the quality of the area's infrastructure. This study aims to identify and analyze the existing slum conditions based on basic infrastructure, land use, building density, and environmental quality, and to develop a spatial planning concept based on spatial analysis to produce an adaptive and sustainable site plan. The methods used include a physical survey in the field, involving 81 respondents through crowdsourcing, and a Weighted Overlay analysis based on the criteria outlined in the Regulation of the Minister of Public Works and Public Housing No. 14/PRT/M/2018. The results showed that 56% of respondents identified building quality as the main factor contributing to slum conditions, followed by drainage problems at 23%. The spatial analysis identified a severe slum area of 9.220 m² located in the southern part of CU 07, while the mild slum area reached 61.210 m². The projected population of Babakan Raya in 2044 is estimated to accommodate 6.500 people, with a density of approximately 573 people per hectare. As a technical response, a spatial plan for the development of the area was prepared in accordance with SNI 03-1733-2004 to improve building layout, drainage systems, and environmental quality in the future. Implementation of this plan is expected to create a healthier, safer, and more sustainable residential environment.]]>

<![CDATA[District geothermal systems require reliable and efficient pressurized circulation and limited thermal dissipation in buried piping, yet design studies often report hydraulic or thermal behavior separately and rarely translate results into maintenance priorities. This study develops a one-way hydraulic-thermal screening workflow aiming to enhance the geothermal energy sustainability by designing a cyber-physical systems baseline. In the district closed-loop geothermal network, EPANET was used to model the full pressurized hydraulics system, while the heat-transfer calculation was evaluated separately from heat loss and heat exchange, coupled with hydraulic values. The operating cases used in the system is a 42-node, 40-pipe network with three 350 HP pumps, and an elevation range of 70-116 m. Outputs from EPANET, including link flow, velocity and head values were then exported to a separate steady heat loss calculation based on radial heat transfer under a uniform supply-return screening scenario. The methodological novelty in this study is the explicit combination of EPANET hydraulics with pipe-level heat-loss screening to investigate maintenance-critical pipes in a closed-loop geothermal network, rather than only reporting system operating metrics. The simulations indicate daily pumping energy of 17,896.8 kWh under the assumed work cycle with hydraulically acceptable velocities of approximately 3-5 fps. The average heat loss in the system is at around 0.0357 kWh/day with almost half of the system’s pipes are pipes with heat loss values above average and considered critical. These pipes are the overheat pipes with wider diameter and mostly considered as main transmission pipes in the geothermal system loop. The use of enhanced insulated pipes and automated sensing devices installations in these critical pipes in the geothermal construction plan would create a significant contribution towards the operation and maintenance work and overall system’s sustainability. This result is interpreted as a design-stage decision-support screen rather than a bankable estimate of lifecycle sustainability gains.]]>

<![CDATA[Early pavement distress due to permanent deformation and fatigue cracking remains a major challenge for flexible pavement infrastructure in Indonesia, particularly under high traffic loading and tropical climatic conditions. Meanwhile, the Indonesian palm oil industry generates more than 23 million tons annually of Empty Fruit Bunch (EFB), which has not yet been optimally utilized as agro-industrial waste. This study investigates the utilization of EFB fibers treated with NaOH alkali and coated with asphalt emulsion as an additive in Asphalt Concrete Wearing Course (AC-WC) mixtures using the dry-mix method. The experimental variables include two fiber lengths (0.5 cm and 1 cm) and three fiber contents (0.2%, 0.4%, and 0.6%), while maintaining a constant Optimum Asphalt Content (OAC) of 6%. Marshall testing was conducted in accordance with SNI 2489:2018, referring to the Bina Marga General Specifications 2025. The results indicate that fiber incorporation enhances stability up to 1,748.80 kg and increases the Marshall Quotient (MQ) to 530.24 kg/mm, compared to the control mixture with stability of 1,666.16 kg and MQ of 512.33 kg/mm. Volumetric analysis shows a reduction in VIM (4.14-4.32%) and VMA (18.76-18.86%), along with an increase in VFA (77.08-77.92%). The Optimum Fiber Content (OFC) is identified at 0.5 cm fiber length with 0.4% fiber content, yielding stability of 1,748.80 kg, MQ of 530.24 kg/mm, VFA of 77.66%, and an Immersion Residual Strength (IRS) of 90.79%.]]>

<![CDATA[Indonesia’s palm oil industry generates large volumes of palm oil mill effluent (POME) characterized by high organic load and suspended solids, requiring effective treatment. This study evaluates a continuous hybrid system consisting of a kapok fiber(KF) pre-treatment unit, electrocoagulation (EC) reactor, and Moving Bed Biofilm Reactor (MBBR), operated under varying plate materials (Fe, Al, Cu) at 24 V and 10 A. The system treated raw POME (pH 3.4; sCOD 20,796 mg/L; TSS 25,610 mg/L; oil and grease 3,243mg/L) over 10-day operational cycles per condition. Results show that copper electrodes achieved the highest performance, with sCOD removal up to 66% and oil and grease removal up to 81.38%, alongside improved TSS reduction. The KF unit contributed 46–53% oil and grease removal, while EC primarily reduced suspended solids and adjusted pH, supporting stable MBBR performance. The combined configuration highlights the interaction between physicochemical and biological processes, where electrode selectionand pre-treatment significantly influence overall system efficiency. These findings provide insight into optimizing integrated treatment strategies for high-strength POME, although additional polishing steps are still required to meet discharge standards.]]>
