<![CDATA[Sustainable waste management in river basins is often hampered by sectoral egos and overlapping mandates. Despite various regulatory efforts, the intersection between legal norms, regional planning, and global sustainability targets remains poorly coordinated. Purpose: This study aimed to analyze the integration of waste management policies by correlating local regulations, development planning frameworks, and the Sustainable Development Goals (SDGs), with a focus on how the instruments could be harmonized to improve environmental outcomes. Methods: The analysis used a normative juridical method combined with public policy analysis, focusing on the assessment of legal norms, regulatory hierarchy, and regional development planning documents, with Bima City Regulation No. 3 of 2018 as a case study. Results: The results showed that current waste policies were fragmented and lacked effective integration. Although local regulations provided legal legitimacy for waste management, the policies were poorly synchronized with development planning instruments and specific SDG targets. Key structural gaps included weak enforcement mechanisms, deficient institutional coordination, and the absence of a legal framework for a circular economy. Conclusion: The lack of policy integration severely hindered the effectiveness of sustainable waste management initiatives. Suggestion: This study suggested strengthening regulatory correlation, integrating watershed-based management directly into development planning, and legally embedding circular economy principles. Contribution: The analysis further contributed to environmental governance by developing a novel interdisciplinary, integrative policy framework that bridged the gap between regulatory hierarchies, spatial planning, and sustainability objectives, offering a scalable model for river basin protection in developing jurisdictions.]]>
