The Study of Estimation of Landfill Capacity through Dynamic System Approach

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.

Analysis of the factors that influence the environmental quality index in Bekasi Regency

“…This issue is highly intricate and challenging to solve. Another significant problem to address, particularly in emerging nations, is the lack of land utilized for final garbage disposal (landfill) (Warlina and Listyarini 2022). Meanwhile, population growth and population migration are the supporting factors that most influence the EQI in Bekasi Regency.…”

Complexity of Waste Handling Technology at Final Disposal Site of Bantargebang, Bekasi City

“…The CO, O3, NO2, PM10, and SO2 indices are in the good category (1-50), while the PM2.5 index is moderate (65,992). The results show that the air quality at the WTE final disposal Bantargebang"is still acceptable for human health [7]. WTE electricity production in 2022 is shown in Table 4.…”

“…The Bantargebang final disposal waste pile if simulated with the current situation will reach 36, 861, 653 tons in 2030. [7] the various technologies applied at Bantargebang final disposal have not been able to have a significant impact on reducing waste piles at Bantargebang final disposal, this must be supported by a thorough study to obtain the most suitable multi-technology scenario to be applied in Bantargebang final disposal management. This research will provide an overall picture regarding the existing state of Bantargebang final disposal which includes the technological capabilities available at Bantargebang final disposal to reduce waste generation and also its impact on the environment.…”

Characterization, risk assessment, and potential utilization of fly ash from PLTSa Merah Putih at Bantargebang, Bekasi, Indonesia

“…The landfill is the most common method of solid waste disposal in Indonesia; however, it can cause environmental deterioration if not managed properly. Solid waste 1201 (2023) 012048 IOP Publishing doi:10.1088/1755-1315/1201/1/012048 2 management is now in a state of an emergency situation, particularly in big cities due to overcapacity at its landfill sites [2].…”
