ABSTRACT: This study aims to evaluate the sustainability of post-mining land at PT Insani Baraperkasa (PT. IBP) using the Multidimensional Scaling (MDS) method to offer recommendations for land management that incorporates technical and quantitative approaches aligned with sustainable development principles and environmental protection in mining areas. The study examines five (5) main dimensions (environmental, social, economic, technical, and institutional), using a combination of data collection methods such as surveys, environmental impact assessments, and social dialogues with local communities. The MDS method provided a quantitative analysis of sustainability across these dimensions, offering a comprehensive evaluation of post-mining sustainability. Results indicated that PT. IBP overall sustainability index is moderately sustainable, with an average score of 61%. The dimensions of economics and technical aspects scored relatively higher, indicating positive progress. However, the social dimension, particularly Community Anxiety (S4) and High Conflict (S2), showed significant room for improvement. Quantitative recommendations to address High Conflict (S2) include adjustments in blasting schedules, improvement of community infrastructure, and regular stakeholder consultations. Environmental management strategies, such as rehabilitating the Riparian Ecosystem (S3) and promoting Biodiversity (S2) conservation, were also emphasized to enhance environmental sustainability. In conclusion, this research highlights the necessity of integrating technical methods and multi-dimensional management strategies spanning environmental, social, economic, technical, and institutional factors to achieve long-term sustainability in post-mining areas.
