Penentuan Zona Kelayakan Tempat Pembuangan Akhir (TPA) di Kabupaten Sumbawa Menggunakan Analisis Spatial Multi Criteria Evaluation
Keywords:
Environment, feasibility,, spacial, wasteAbstract
Sumbawa Regency is the district with the largest population on Sumbawa Island. This demographic bonus is in line with the increase in the amount of waste produced. In 2021, the mass of waste produced by Sumbawa Regency will reach 187.04 tons per day. Sumbawa Regency already has a Raberas Final Disposal Site (TPA) with an area of 6 hectares. However, it is necessary to carry out an up-to-date analysis regarding the feasibility of a landfill to handle waste problems in Sumbawa Regency. Therefore, it is necessary to conduct a feasibility study on the landfill based on spatial analysis so that it does not have a negative impact on the surrounding environment. By conducting comprehensive spatial-based research, it is hoped that the Raberas TPA will be feasible or unsuitable based on feasibility criteria analysis. The research results show that the overall feasibility score for Raberas TPA is 740, meaning that based on the feasibility interval class, Raberas TPA is included in the category of TPA whose existence is worthy of consideration. The results of this research can provide benefits for the government in improving the quality of the environment in Sumbawa Regency, especially the people who feel the direct impact related to the TPA feasibility study, so that if the Raberas TPA is deemed to be no longer feasible, then they can minimize the negative environmental impact by building a new landfill that meets the eligibility requirements.
