The first hue of environment in the Reclamation Plan area is a sengon tree land that has been planted by the company's previous IUP owners. The stages of reclamation planning in this former mining land such as, land preparation, land stewardship, and revegetation. Land preparation is done for 1 day for the demolished the facilities and infrastructures that exist in reclamation plan. Land stewardship carried out land flattening by using bulldozer with a blade capacity of 3,512 m3 for 72 days and flatten 7 bumps with a volume of 50,930 m3. The drainage is made by excavators with a 0.8 m3 bucket capacity and a planned drain volume is 99.31 m3. The spread of soil is done with the pot system because of the limited number of soil shoots in the region reclamation plan. Revegetation is done based on the first hue of environment in the Reclamation Plan area. The suitable crops are sengon trees and LCC with a total of 2,183 seedlings. At this reclamation planning conducted a detailed cost planning that consisted of direct costs and indirect costs. The planned direct cost is Rp 375.558.050,00.
