Rising energy prices and energy scarcity are driving the use of renewable alternative energy sources. However, the use of renewable energy in Indonesia is only 11.5%, far from the 23% target in 2025. One of the potential alternative energy sources is biogas, which is produced from organic waste such as biomass waste and human and animal waste. Biogas production from market waste can be an environmentally friendly solution by utilizing the residue as compost material. In Bandung city, waste is a major problem that is difficult to solve, so this study aims to analyze costs and take advantage of the application of Dry Biodigester in the use of biogas in small markets. The method used in this study is a mixed method, by first conducting qualitative research to identify the handling of impacts through literature studies and interviews. Furthermore, quantitative research was carried out to explain and analyze the feasibility of applying Dry Biodigester using social cost-benefit analysis techniques based on the results of literature studies, interviews, and observations. Thus, the results of this study are expected to provide theoretical use in PWK science, particularly regarding the application of social cost-benefit analysis techniques in the context of the feasibility of applying Dry Biodigester. In addition, the results of this study can be used as input for stakeholders as material for planning and implementing Dry Biodigester on a micro scale. Based on the results of the analysis, the application of Dry Biodigester generates various values which are grouped as components of costs and benefits of components, both measurable and non-measurable. The impact of the costs incurred is development costs and operational costs, as well as incentives and costs for waste management. While the resulting impact benefits are biogas products, benefits of community participation, and benefits of reducing the volume of waste. By using several assumptions and calculations over a 10-year utilization period, the results of this study provide a social benefit value that is greater than the resulting social benefit value. Thus, it can be concluded that Dry Biodigester is feasible to be implemented in the Simple Market in terms of costs and social benefits generated. However, all the positive results obtained are inseparable from community participation. based on community sensitivity analysis provides significant social benefits. Without community participation, the implementation of Dry Biodigester can only pay for operational costs from TPS.
