<![CDATA[Bagendung Landfill is located in Bagendung Village, Cilegon City has been operational since 1998. with a land area of 10 hectares, this TPA has a waste management capacity of up to 668 tons/day. Aims: To calculate the environmental risk index of the Bagendung Landfill and evaluate its management using the Environmental Risk Index Assessment method, known as the Integrated Risk-Based Approach (IRBA), and to provide actionable recommendations for enhancing waste management practices at the landfill. Methodology and results: The research utilized secondary data analyzed through the IRBA method, adhering to the framework outlined in the Minister of Public Works and Public Housing Regulation No.3/2013 concerning the Provision of Facilities and Infrastructure to Handle Domestic Waste and Domestic Waste Equivalents. The analysis revealed a risk index score of 515.25 for Bagendung Landfill, placing it within the medium-risk category. Conclusion, Significance, and Implications: The landfill’s operations can continue with gradual rehabilitation transitioning into a controlled landfilling system. It is necessary to adopting modern waste management technologies, including Refuse-Derived Fuel production, landfill mining, and enhanced methane gas monitoring systems, to mitigate environmental risks. The integration of pH as an additional parameter in risk assessment and leachate evaluation is recommended to enhance the precision of environmental monitoring and better predict contaminant behavior. Implementing these measures is expected to minimize environmental impacts, extend the operational lifespan of the landfill, and contribute to the reduction of greenhouse gas emissions. Collectively, these efforts align with the objectives of sustainable waste management for Cilegon City.]]>
