Evaluation of municipal solid waste transportation and cost analysis: case study in Banyuwangi Regency

Abstract

Population growth in Banyuwangi Regency reached 0.61% BPS Banyuwangi Regency, 2022) with waste generation reaching 1,963,033.98 m3/year. Only 13% of the waste that is transported to the Temporary Disposal Site, TDS (RPJMD, 2021) is generated in Banyuwangi Regency in 2022; its waste generation in 2022 is 5378,2 m3/day with existing transportation using 17 units of dump trucks and 5 units of arm-roll trucks. The aim of this paper is to evaluate the most effective and optimal waste transportation system and estimate vehicle operating costs. The research methods were field studies and interviews with staff, drivers, and waste workers. The main information needed is the distance between the TDS and landfill sites locations, the time between locations, and the operating time of the waste trucks. The results showed that the amount of waste transported daily was 211.89 m3/day with a proportion of 4%. Optimization is carried out by setting aside distances on eight dump truck routes using the nearest-neighbor method with the R algorithm. Based on optimization, the distance reduction achieved by sorting eight dump truck routes reaches 102.95 km. In Banyuwangi Regency, the average daily vehicle operating costs for waste transportation are IDR 625,600 for arm roll trucks and IDR 3,325,200 for dump trucks. The average vehicle operating cost per year for 5 arm-roll trucks and 17 dump trucks reaches IDR 4,277,304,940.
