Abstract

Acid mine drainage generates environmental liabilities that mining operators must translate into measurable management costs. This study assesses the cost-based environmental liability of acid mine drainage management within the Integrated Geo-Hydrochemical Risk Assessment (IGHRA) framework by linking pollution risk, treatment performance, and environmental cost into a single risk-to-cost evaluation. The study uses source characterization, mine water quality data, compliance-based risk indicators, treatment performance, and operational cost components to estimate two principal cost categories, namely restoration cost and preventive expenditure cost. Restoration cost represents the annual cost required to restore contaminated mine water until all regulated parameters comply with the applicable standard. In contrast, preventive expenditure represents the five-year cost required to suppress future acid generation from potentially acid-forming material through selective handling, temporary stockpiling, installation of compacted clay cover, and runoff control. The results show that the only CaO scenario produces the lowest treatment cost, but does not achieve full compliance because sulfate remains above the standard. The CaO 10 g/L and BaCl₂ 3.0 g/L scenario achieves full compliance and provides the most economical restoration cost among the compliant options, with an estimated value of IDR 516,463,856 per year. The total preventive expenditure cost over five years reaches IDR 3,832,950,186. At a midpoint selling price of IDR 89,000 per ton, the compliant CaO and BaCl₂ scenario exerts an environmental cost pressure of 8.58 percent on projected gross revenue. These results show that the IGHRA framework can convert acid mine drainage risk into measurable environmental liability and can support technically grounded and economically accountable mine water management.

Abstract

Disaster risk reduction (DRR) education is critical in disaster-prone Indonesia, including vulnerable Tangerang Selatan. Disaster-safe educational units (SPAB) aim to enhance school community preparedness, yet implementation remains suboptimal, requiring comparative school evaluations. This study compares DRR education implementation in SPAB at SMAN 5 and SMAS Al Adzkar Tangerang Selatan, focusing on the school community's preparedness level. A mixed methods approach with an explanatory sequential design was employed, involving 373 respondents (principals, teachers, students, and non-teacher staff). Quantitative data were collected via written tests and structured questionnaires, while qualitative data came from in-depth interviews and observations. The results indicate that students’ understanding of disaster threats at both schools was “Very High” (average score >3.21 out of 4), while teachers and educational staff scored “High” (average 2.41–3.20). Understanding of disaster risk among principals, teachers, and educational staff was “Medium” (average 1.00–1.07 out of 2), with students at SMAN 5 scoring “High” (1.38) and students at SMAS Al Adzkar “Medium” (1.19). The average score for understanding disaster capacity across all groups was in the “High” category. Qualitative findings reveal that the integration of disaster risk reduction materials into the curriculum remains limited to certain subjects, the development of specific disaster risk reduction teaching materials is suboptimal, and extracurricular activities at both schools are not explicitly designed as part of disaster risk reduction efforts. These results highlight the need to strengthen SPAB implementation comprehensively by enhancing preparedness, curriculum integration, instructional materials, and extracurricular programs to improve resilience in disaster-prone schools.
