Prioritization of risks associated with mining permit restrictions in Indonesia’s new capital region: analytic hierarcy process and fuzzy-analytic hierarcy process approach
摘要
The relocation of the capital of Indonesia to East Kalimantan has introduced a policy restricting the expansion of mining business permits as part of the sustainable development agenda. While aligned with long-term environmental and governance objectives, this policy generates potential risks for government institutions, industry, and local communities. This study applied the Analytic Hierarchy Process (AHP) combined with Fuzzy AHP to identify and prioritize these strategic risks. A hierarchical framework was constructed based on four main criteria—economic, regulatory, social and environmental—further elaborated into 21 sub-criteria validated through literature review and expert consultation. The sub-criteria were derived using a multi-stage process involving literature synthesis and expert judgment to establish content validity prior to the AHP–Fuzzy AHP analysis. Data were collected via structured expert questionnaires and analyzed using triangular fuzzy number weighting and ratio consistency testing. The results indicated that economy risks, particularly reduced investment and rising compliance costs, hold the highest priority weight (0.302), followed by social risk (0.274) and regulation risks (0.240). Environmental risks (0.184), while comparatively lower in aggregate weight, remained critical in relation to reclamation obligations and pollution management. These findings provide a basis for evidence-based mitigation strategies and support a just and orderly transition in mining governance during the establishment of the new capital region.
