In practice, the designation of WIUP is not merely administrative in nature but is intrinsically linked to the spatial planning system as an instrument for controlling land use. Legal issues arise when mining regulations provide flexibility in the designation of WIUP, while spatial planning regulations require conformity between proposed activities and spatial plans as a prerequisite for licensing. This divergence in normative construction generates potential disharmony and legal uncertainty. Against this background, this study examines the mechanism for determining WIUP under both regulatory regimes and evaluates its legal framework based on the principle of legal certainty and maqasid al-shariah. This research employs a normative juridical method using statutory and conceptual approaches. The theoretical framework is grounded in the theory of legal certainty developed by Gustav Radbruch, who positions legal certainty as one of the three fundamental values of law, alongside justice and expediency. This theory is applied to assess the clarity, consistency, and harmonization of norms governing WIUP. In addition, this study adopts the contemporary theory of maqasid al-shariah as developed by Jasser Auda and Yusuf al-Qaradawi, particularly with regard to environmental protection as an integral objective of law. The findings indicate that the mechanism for determining WIUP under mining regulations has not been fully integrated with the spatial planning system, thereby creating normative tension and potential legal uncertainty in the issuance of mining business permits. From the perspective of legal certainty, weaknesses are identified in the clarity of normative limitations and regulatory synchronization. From the standpoint of maqasid al-shariah, excessive flexibility in WIUP designation without clear parameters risks undermining the principles of public welfare and environmental protection. Accordingly, a harmonized regulatory reconstruction of WIUP is necessary to ensure legal certainty and to maintain a balance between resource utilization and environmental sustainability. %K WIUP, Tata Ruang, Kepastian Hukum, Maqasid Syariah, Perlindungan Lingkungan %D 2026 %I UIN SUNAN KALIJAGA YOGYAKARTA %L digilib76996
