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.
