【 摘 要 】

The loss of the vegetation indirectly had removed the functions of the forests in regulating water system, controlling erosion and flood, absorbing carbon dioxide, supplying oxygen and controlling temperature. One of the efforts done to restore the quality of the environment around mining areas was by doing reclamation in accordance with the Regulation of Indonesian Government No. 78 Year 2010. This research applied cross-sectional design. The sample was taken in the areas vegetated. The variables studied were the chemical content of the soil (N, P, K, Ca and Mg), pH and Cation Exchange Capacity. The sample spread out in five areas reclaimed in Sungai Tambang PT Karbindo Abesyapradhi. The result of the research showed that the reclamation was done by planting sengon and acacia trees. The fertility of the soil (clay texture, acidity, Ca, Magnesium, Cation Exchange Capacity of the soil, C-Organic and N-total of the soil) in the reclaimed areas was similar. However, partially affecting both plant growth and sengon acacia tree is a cation exchange capacity and Soil Texture. It was recommended to PT Karbindo Abesyapradhi to maintain and care for reclamation has been done, because if based on the evaluation of the report on the implementation of reclamation showed reclamation does not meet the criteria of success, the Minister, the Governor, or the Regent / Mayor in accordance authority may assign a third party to conduct reclamation activities or entirely by using collateral reclamation.
