Design of 3R solid waste processing facility (TPS 3R) in Tanjung Village as the development of municipal solid waste management facilities in North Lombok Regency

Municipal solid waste management in Tanjung Village that has not been fully served has caused the village sanitation level to deteriorate and triggered health problems, especially Dengue Fever in the rainy season. This research is expected to be able to correct the problem as a fulfillment of various government policies. This study aims to determine the percentage of areas covered. Units in the TPS 3R are based on the composition and characteristics of the waste and available land area; calculate the value of mass balance and total percentage recovery of TPS 3R. Waste generation and composition were analyzed according to SNI 19-3964-1994, while the characteristics were tested using proximate and ultimate analysis. The percentage of the area served is 36.02%. Units in TPS 3R, namely receiving and sorting location; chopping and drying of the organic waste area; active waste composting area; maturation area; sifting and compost packing area; compost warehouse; waste warehouse stall; office; parking lot; equipment warehouse; and leachate holding area with total land needed 2 347.26 m². Mass balance shows that managed waste is 753.08 kg/day, wet waste recovered is 416.57 kg/day, dry waste recovered is 141.25 kg/day, and residual waste goes to landfill 195.27 kg/day that the total percentage of recovery is 74.07%.
