Abstract

Leachate from the Final Disposal Site (TPA) in Piyungan, Yogyakarta, is a significant source of potential heavy metal contamination. This represents a serious environmental issue as it can pose a threat to human health and ecosystems. Given its significant negative impact, this study aims to evaluate the efficiency of Compost-Based Activated Carbon (CBAC) as an environmentally friendly alternative solution for reducing heavy metal concentrations in leachate. CBAC is produced through a pyrolysis and chemical activation process using 32% HCl. The study tested the ability of CBAC to adsorb Cr, Cu, and Pb from leachate samples. The results indicate that CBAC exhibits significant adsorption capacity, with the highest removal efficiency recorded for copper (Cu), reaching 52.38% in 20 minutes. The removal efficiencies for chromium (Cr) and lead (Pb) were 17.8% and 12.09%, respectively, although at different optimal times. These differences in efficiency suggest that the characteristics of each heavy metal influence its interaction with CBAC. The findings demonstrate the potential of CBAC as an effective and sustainable alternative in waste management, particularly in reducing heavy metal pollution. This study makes a significant contribution to the development of more environmentally friendly and sustainable waste management technologies, offering an innovative solution to address heavy metal contamination issues at TPA Piyungan and similar sites.

Abstract

Indonesia has experienced a significant period of community-based waste management that has gained global recognition. Initiatives such as waste banks, 3R waste processing facilities (TPS 3R), waste donation programs, and creative communities such as Pandawara Group reflect the strength of public participation in addressing waste-related challenges. However, these approaches have begun to reveal their limitations, as they are often sporadic, unsystematic, and insufficient to address structural issues, including inadequate waste management services, institutional dualism between regulators and operators, and limited local government financing. Indonesia is currently facing emerging challenges, such as overcapacity at final disposal sites (TPAs), landfill fires, leachate pollution, and increasing waste generation driven by rapid urbanization. This article aims to analyze the transition of waste management in Indonesia from a community-based approach toward a modern system that incorporates Waste-to-Energy (WtE) technology. The study was conducted through a literature review and policy analysis of waste management practices implemented across various regions. The findings indicate that the success of this transition depends not only on technological and infrastructural readiness but also on the integration of formal waste management systems with community participation at the grassroots level. Future waste management models in Indonesia should position communities as strategic partners within the WtE framework in order to achieve waste management that is equitable, efficient, and sustainable.
