Abstract
The contribution of coal mines is to generate foreign exchange, which can be utilized to grow the regional economy. However, coal mining has the potential to damage the environment. Post-mining management using the revegetation model can improve the environment and contribute to society. The focus of this study is to optimize the proposed revegetation in the post-coal mining area using Acacia Mangium (AM) and Sengon (S) plants. Research methods include calculating the growth rate of plant biology, assuming the same growth parameters, and calculating economic feasibility so that the business can contribute. A mathematical model to determine the feasibility of a commodity based on Faustmann's forest economy theory and the Chapman-Richards equation to estimate the rate of biological growth of trees. Mathematical models are programmed in Microsoft® Excel, then spreadsheet results are used to determine the optimal contribution of the revegetation of commodity crops. The Acacia Mangium (AM) commodity benefits the fifth year with a total volume of 306,780 m3, and a land area of 2,000ha. Sengon Commodity (S) gives profit in the tenth year with volume of 31,661.76 m3 for 83ha land area. This research was conducted based on master plan of allotment of coal mining in Muaraenim Regency of South Sumatera Province
