Pameungpeuk sub-district is one of the sub-districts in the Ciatrum watershed with the Cisangkuy sub-watershed. There are four villages crossed by the Cisangkuy River, including Sukasari Village, Langonsari Village, Rancamulya Village, and Rancatungku Village. The generation of waste in the four villages is estimated to be higher due to the increase in population each year and urban growth. Based on the observations and questionnaires given to 100 respondents, 51% said that there had been a waste service. Around 41% said that there was no garbage service, which burned the existing waste independently or collectively. Garbage that officers have transported will be collected at a garbage collection point which will burn periodically. This is due to the absence of waste transportation to the TPA due to lack of funds and the absence of a waste processing site. These problems underlie the need for good and appropriate waste management to support independent waste management. The planned waste management is a decentralized system where waste from residential areas will be processed at Recycling Centers (PDU), built-in each village. Waste management system planning is carried out based on primary data and secondary data. Preliminary data includes a sampling of waste based on SNI-19-3964-1994, lab tests, surveys that include interviews and questionnaires regarding waste management patterns. Secondary data has population, regional characteristics, and related data that support planning. The planning period is 20 years, which will be carried out starting from the first stage in 2021 in the form of system planning and making PDU, the second stage in 2022 in the form of PDU construction and community preparation related to the waste management system and the last step in 2023-2042 in the form of operating PDU facilities. The planning used is the business as the usual type where the percentage of waste that goes to the PDU is 100%. For the selection of alternative systems, the Simple Additive Weighting (SAW) method is used. Based on this method, the selected system was obtained in the form of semi-manual sorting technology using a conveyor belt, processing organic waste in the form of Black Soldier Fly (BSF) larvae, processing inorganic waste by making plastic pellets, compacting, and selling rubber and glass materials, and burning the remaining material with incineration. Based on the calculation results, the construction of a PDU of 20 tons/day requires a minimum land area of 1241.26 m2, and a PDU of 10 tons/day requires a minimum land area of 648.54 m2. One example of a PDU design will be carried out in Sukasari Village with 20 tons/day PDU type. Other programs to support the running of the PDU and invite the community to participate in waste processing actively can integrate the concept of waste bank and waste management with PDU.
