Abstract

Abstract : In line with the increase in population, the production of waste will also grow every year. Unfortunately, the land used for final waste disposal (landfill) is extremely limited, especially in developing countries. This study aimed to predict landfill capacity in accommodating waste from the community based on daily waste input using a dynamic system and to provide alternative policies on landfill waste management. The analyzed data consisted of primary and secondary data, whereas the simulations applied system dynamic approach using Vensim software. The simulation results indicate that the waste production will reach 36, 861, 653 tons in 2030 if nothing is done. Assuming that all waste from the surrounding communities is accumulated in one landfill, Bantargebang landfill can only accommodate until 2022. To be able to use Bantargebang landfill up to 2030, the waste production must be reduced by 50% for organic waste and 50% for inorganic waste. From the analysis, it is proven that composting reduces a greater amount of waste than other waste reduction methods, namely recycling or reusing, by the same percentage. Waste sorting is therefore highly recommended to be done by the community in every household as a basis to facilitate further handling. The community can play an active role in reducing waste, e.g., by composting organic waste and recycling or reusing inorganic waste. Furthermore, regulations should be made that can give punishment to households that do not carry out segregation. Reliable infrastructure for waste management needs to be facilitated, and counseling/training/outreach on waste sorting to the community must also be provided at the district level.
