PT. Jorong Barutama Greston is a company engaged in a coal mining. This area which became the research is disposal UC_East pit area of 18,94Ha. Mining activities will always have a negative impact on the environment that changes color and shape of the natural environment, so that the required reclamation activities to address environmental issues in order to function optimally in accordance with us. Reclamation activities is landscaping andrevegetation landscaping.The activities namely structuring topsoil, while the arrangement of topsoil used methods pots / planting hole with topsoil required volume 110,799LCM.The seems time required forthe arrangement of top soil is 39 days. Plants used in revegetation activities there are two, namely cover crops or cover crops such as nuts - nuts and plant a core of acaciasengon (Albiziachinensis). The purpose of revegetation is to recover the carrying capacity of the land to crops that can provide benefits to communities around the study site . The purpose of this study was to determine the magnitude of erosion and the magnitude of the danger of erosion (TBE) in various types of land units reclaimed in the PT. Jorong Barutama Greston.The result showed that the amount of erosion occurred in Land Unit V 618,18tonnes/ha/yr is higher that other land units, but after rehabilitation the total hazard erosion (TBE) at the light of land unit V 61,82tonnes/ha/yr. Keywords: reclamation, landscaping, top soil andrevegetation.
