Abstract

Energy transition at the village level plays a crucial role in Indonesia’s strategy toward sustainable energy independence. This research examines the biogas-based renewable energy development in Argosari Village as a model of community-driven sustainability. The study integrates qualitative and quantitative analyses—spatial, environmental, and economic—using IPCC guidelines, Location Quotient (LQ), Internal Rate of Return (IRR), and Net Present Value (NPV). The research involved interviews with 45 households, three focus group discussions with farmer associations, and secondary data from the Malang Regency Bureau of Statistics. Results show that 57% of households have installed biogas units, reducing GHG emissions by approximately 60% (1.2 tons CO₂ per household annually), and achieving a B/C ratio of 1.75. Sensitivity analysis indicates project feasibility remains positive even under ±15% variation in maintenance and subsidy levels. Comparative analysis with rural biogas programs in India and China highlights Argosari’s unique integration of social, economic, and environmental benefits. This study contributes a replicable framework for community-scale renewable energy implementation in rural Indonesia.

Abstract

Rapid urban growth in the Graha Raya area, Tangerang, has created serious challenges for the drainage system. Drainage problems have become a crucial issue in rapidly developing urban areas such as Graha Raya, Tangerang Regency. Flooding and water ponding frequently occur due to the insufficient capacity of the existing drainage channels. This study aims to evaluate the adequacy of the existing drainage channel capacity against the design discharge as part of flood mitigation efforts. The research methodology includes the collection of hydrological and channel morphology data, calculation of runoff discharge using the Rational Method, and analysis of the hydraulic capacity of drainage channels by considering channel dimensions, slope, and roughness coefficients. The analysis results indicate that several major drainage channels in Graha Raya are unable to accommodate the design discharge under certain return periods. For the 25-year return period, with a rainfall value of 187 mm/day, the design discharge exceeds the channel capacity in several segments. Therefore, adjustments to the hydraulic dimensions are required to improve the performance of the drainage system and minimize the potential for flooding in the study area.

Abstract

Tidal flooding is not only caused by seawater intrusion but also reflects the complexity of urban environmental problems. Contributing factors include land subsidence due to excessive groundwater extraction, inadequate drainage systems, degradation of mangrove ecosystems, and land-use changes resulting from coastal reclamation. Therefore, this study examines the recurring phenomenon of tidal flooding in the coastal areas of Penjaringan District, North Jakarta, particularly in Muara Angke, Muara Karang, and Muara Baru. This study employs a mixed-methods approach through direct field observations, in-depth interviews with residents and community leaders, and the distribution of questionnaires to 100 respondents in the affected areas. The results indicate that tidal flooding has significant impacts on the economic, social, and health aspects of the community. Daily activities are disrupted, household incomes decline, and the risk of disease increases due to poor sanitation conditions during flood events. Although communities have implemented various adaptation measures, most respondents perceive that government interventions have not been effective or equitable. This study emphasizes the importance of collaboration between the government and local communities in developing water control infrastructure, rehabilitating mangrove ecosystems, improving drainage systems, and providing education and economic assistance to enhance the resilience of coastal communities to tidal flooding.

Abstract

This study was conducted to analyse the suitability of the Temporary Waste Management Site (TPSS) location for the appropriate zone based on population, density, and land area in RT 008, Rorotan Village, Cilincing District, North Jakarta. The purpose of this study was to evaluate the suitability of the current TPSS location and to provide data-based recommendations for a more environmentally friendly site that meets community needs. The methodology used was descriptive quantitative with a direct interview approach with 30 randomly selected respondents. Data were analysed by categorising respondents' answers into three groups: agree, disagree, and neutral regarding the suitability of the TPSS location. The results showed a varied distribution of opinions: 43% of respondents agreed because the location is far from residential areas and its cleanliness is maintained; 37% disagreed because of air pollution and the cramped location; and 20% were neutral. The main conclusion is that the TPSS location in RT 008 is highly unsuitable, as it could cause environmental pollution and health problems. This study recommends constructing a wall to reduce unpleasant odours and expanding the TPSS area to accommodate the increasing volume of waste.
