The Patommo-Sidrap Landfill Lifespan Estimation

Abstract Sidenreng Rappang (Sidrap) Regency has a landfill called the Patommo landfill, which has implemented a sanitary landfill model. Patommo landfill is located in Patommo Hamlet, Arawa Village, Watang Pulu District, Sidrap Regency, approximately ± 3 Km from Lawawoi, the capital of Watang Pulu District, and ± 10 Km from Pangkajene, the capital of this regency. This landfill has adequate facilities and infrastructure as a sanitary landfill. The waste transported to the landfill is managed in five stages: weighing, demolition, distribution, solidification, and covering the waste with soil. This study focuses on the lifespan of the Patommo landfill in the Sidrap district. The lifespan is obtained by calculating the amount of total waste per year, waste density, waste volume, and the prediction of the amount of waste in the future based on population growth. This research takes reference data from 2016, which will be compared with current conditions. The results of analyzing data obtained the average value of the waste density of Sidrap District is 1379.51 kg/m3. Therefore, the volume of waste entering the Patommo landfill is 47,395.95 m3. The total volume of landfill capacity is 1,708,737.64 m3, with a volume for soil cover of 624,300.64 m3, and the waste volume is 1,084,447 m3. Estimating the lifespan of the Patommo landfill without reduction efforts is 17 years or will be full in 2033, while the estimation of lifespan with reduction efforts is 32 years or will be full in 2048.
