| Summary: | Waste management poses significant challenges, particularly in the Citarum River Basin (DAS) in West Java Province, which was deemed one of the world's dirtiest rivers by the World Bank in 2018. The West Java Environmental Agency reported that in 2023, waste in the Citarum River Basin area reached 15,838 tons per day, with organic waste constituting 55% and plastic waste 15.35%. In response, the Citarum Harum Program, established under Presidential Regulation Number 15 of 2018, aims to mitigate these issues. This study focuses on Sector 12 Sub-sector 3, covering five villages: Sukagalih, Cinangsi, Padajaya, Majalaya, and Cijagang, which face inadequate waste management services, resulting in improper disposal practices. This study employed SNI sampling and SAW method for determining waste management alternatives based on technical, social, environmental, and economic aspects. The results indicate the waste generated in the study area in 2022 reached 13.73 tons/day with the largest percentage of waste coming from households at 98.54%. Waste generation is projected to reach 27.38 tons/day in 2044, with the dominant waste composition being organic waste 83.66%, plastic waste 7.40%, and paper waste 3.18%. The characteristics of organic waste have a moisture content of 58.82% dry basis and a C/N ratio of more than 35, while inorganic waste has a moisture content of 18.84% dry basis and a volatile content of 89.56% dry basis. By using the selected development scenario, waste services are expected to reach 80% in 2044, with waste generation estimated at 21.9 tons/day. Calculations made for the needs of the waste processing system at TPST show a minimum land requirement of 2,172.01 m2 with the selected waste management configuration including waste sorting, composting, semi-manual separation with a conveyor belt, and various processing and storage solutions for recyclable and hazardous waste. The required investment costs are Rp6,836,000,000.00, while the operating and maintenance costs are Rp4,530,257,256.00/year. The NPV is positive at Rp88,199,044,581.47, so the TPST project is economically feasible |
