Khoirul MarzukiauthorWaste management in Indonesia faces complex challenges due to population growth, increasing waste volumes, and limited landfill infrastructure. Yogyakarta City and Banyumas Regency face similar problems but implement different governance approaches. Yogyakarta City experienced a crisis with the closure of Piyungan Landfill in 2024 due to prolonged overloading and low community participation in waste sorting, reaching only 28–40%. Meanwhile, Banyumas Regency successfully managed 99.31% of its waste generation through a zero waste approach based on a circular economy. This study aims to compare waste governance in both regions from the perspectives of Environmental Fiqh (hifz al-bi'ah) and the Sustainable Development Goals (SDGs), as well as to evaluate the alignment of policies with the principles of maslahah and sustainable development. The study employed a juridical-normative approach with qualitative methods. Primary data were obtained through structured interviews with seven key informants from the Environmental Agency, managers of the Piyungan Waste Processing Site, and Banyumas Landfill, as well as field observations at both locations. Secondary data were sourced from relevant regulations, academic literature on Maqasid Syari'ah, environmental politics, and SDGs documents. The theoretical framework encompasses the concept of hifz al-bi'ah as a collective obligation (fardhu kifayah) and SDGs principles. Analysis was conducted descriptively and qualitatively by linking field findings to the Islamic normative framework and sustainable development. The findings indicate that Banyumas Regency is more effective through the strengthening of 70 Community Self-Help Groups, 39 integrated Waste Processing Sites (TPS3R), and innovations in RDF production and Black Soldier Fly maggot cultivation that earned the ASEAN ESC Award 2025, reflecting the principles of dar' al-mafasid and jalb al-masalih. In contrast, Yogyakarta City faces structural obstacles including dependence on conventional systems, weak enforcement of regional regulations, and low community participation that generates potential mafsadah. Differences in waste generation volume and containment capacity are also structural factors that favor Banyumas Regency; however, its primary success lies in a community-based policy commitment that is aligned with the SDGs and Islamic maslahah values.342 Hukum Tata Negara2026-01-28UIN SUNAN KALIJAGA YOGYAKARTA;FAKULTAS SYARI’AH DAN HUKUMThesis
