Abstract

Waste management in Indonesia still faces various challenges, particularly in urban areas such as North Bekasi District, which generates significant daily waste. Innovative technological approaches are required to reduce and manage waste problems, especially combustible waste. Aim: This study aims to determine the most suitable waste treatment technology for combustible waste in North Bekasi District using the TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution) method. Methodology and results: The study evaluates three waste treatment technologies: Refuse-Derived Fuel (RDF) production, incineration, and pyrolysis, based on technical, environmental, economic, and social criteria. Data were collected through primary and secondary methods, focusing on waste characteristics, management conditions, and energy potential. The TOPSIS method analysis identified RDF as the most suitable solution with the highest preference score 0.669, followed by incineration and pyrolysis. RDF technology demonstrates significant advantages, including high calorific value (3623.58 kcal/kg), efficient resource recovery, and lower operational and investment costs. Conclusion, significance and impact study: This study concludes that RDF technology can effectively address waste management challenges in North Bekasi, while also promoting environmental sustainability and economic feasibility. Selecting RDF as the primary technology represents a strategic step toward transforming waste management in Indonesia into a more modern, efficient, sustainable, and technology-based approach.

Abstract

Jalupang Landfill is the only official final disposal facility in Karawang Regency, which is still operated using an open dumping system. This management practice has created several environmental issues, including a fire incident in October 2023, and has raised concerns about the sustainability of its operations. This study was conducted to identify the variables that influence the sustainability of Jalupang Landfill by employing a reflective Structural Equation Modeling (SEM) approach. Primary data were collected through questionnaires distributed to 100 respondents across nine districts who are involved in waste transportation to the landfill. The questionnaire applied a Likert scale and was analyzed using SmartPLS 4.0 through a series of tests, including model fit, construct validity, and path coefficient analysis. The results indicated that the developed model met the fit criteria, with an R² value of 0.622 or 62.2%. The regulatory variable was found to be the most dominant factor, with a path coefficient of 0.400 (p-value = 0.002), followed by the financing variable with a coefficient of 0.286 (p-value = 0.041). These findings highlight that the sustainability of Jalupang Landfill is largely determined by strengthening regulatory aspects and ensuring adequate financial support.
