Based on Act 18/ 2008 (UU 18/2008) and Regional Regulation of Semarang City 6/2012 (Perda Kota Semarang 6/2012) regarding Waste Management states that waste management as a resource that has economic value and can be utilized, one of them for energy. Efforts to develop waste processing into biogas to serve 250 households in TPA Jatibarang conducted in 2019 until 2034. This study aims to determine the feasibility of waste processing into biogas on the utilization of methane gas for household gas in TPA Jatibarang 2019-2034. The research uses quantitative method approach of cost benefit analysis, with data retrieval method through field observation and interview to the parties involved in program implementation. The calculating cost benefit is performed by quantifying the cost and benefit variables of expected impacts with landfill gas (LFG) technology, and comparing with the sensitivity analysis using anaerobic digester (AD) and gasification technologies. The results show that waste processing into biogas on the utilization of methane gas for household gas in Jatibarang landfill is feasible to be continued for the next 15 years either for LFG, AD, or gasification technology. But in side of cost, using LFG technology is better chosen because it is more profitable than the other technologies. While in side of environmental friendlines, using AD or gasification technology can be selected because it is more effective to reduce waste landfill than LFG technology. <br /> <br /> <br /> <br /> <br /> Keywords: waste, biogas, methane gas, TPA Jatibarang, cost-benefit analysis.
