PREDIKSI KEBUTUHAN LAHAN TPA DAN BIAYA OPERASIONAL ALAT BERAT TPA BANJARSARI KOTA BOJONEGORO TAHUN 2031

TPA ( final disposal site)Banjarsari is located in Bojonegoro Regency, has a TPA ( final disposal site) area of ± 4,9 hectares with a population that is increasing day by day resulting in more and more waste generated as a result, the land in the TPA ( final disposal site) will decrease day by day as a result of garbage that continues to accumulate at the TPA( final disposal site) location. , so it is necessary to predict the need for land needed at the TPA ( final disposal site), so that it can prepare the land requirements needed for the next 10 years well and optimally, in waste management heavy equipment has an important role so it is necessary to optimize productivity and operational costs of heavy equipment. In this study, data collection was carried out at related institutions, from the analysis results obtained based on the projected population, the volume of incoming waste in 2021 and 2031 was 35008,211 m3/year and 46811,350 m3/year. With the required land area in 2031, which is 15481,196 m2, with excavator productivity at the landfill site at 138.84 m2/day and bulldozer productivity 141.95 m3/day. Operational costs for heavy equipment excavators are up to Rp. 146.003/hour, and Bulldozer CAT D4K LGP which is Rp. 114,360/hour
