Mine land reclamation is a crucial effort to minimize the negative environmental impacts of mining activities. The primary objective of this paper is to evaluate innovative approaches in mine reclamation, such as the use of biochar, void management, and revegetation techniques, and to analyze their effectiveness in improving soil quality and environmental sustainability. Data from various case studies in Indonesia were analyzed to understand the challenges and opportunities in implementing these reclamation techniques. The study results show that techniques like biochar can enhance soil fertility by improving cation exchange capacity (CEC) and soil pH, revegetation can restore canopy cover and biodiversity through the use of locally adapted plant species, and void management provides opportunities for sustainable water resource development. However, challenges in meeting criteria such as soil fertility enhancement, water quality improvement, and biodiversity restoration still require special attention. This study offers new insights into effective and sustainable post-mining environmental management practices in Indonesia
