Abstract

Reclamation aims to reduce the adverse environmental impacts of coal mining such as erosion, sedimentation, and poor drainage. Soil erodibility is very important to know so that conservation and tillage actions can be implemented in a more precise and targeted manner. This researchis to assess and compare the value of soil erodibility at various of reclamation ages’s in post-coal mining land and forest land as a comparison at PT. Bukit Asam Tbk. The research method used is a survey method (field observation) at the level of detail and laboratory analysis. The research area is ± 10 Ha. The map of the research area has a scale of 1: 20,000 for the location of Pit 1 Timur and a map with a scale of 1: 6,000 for the location of Pit 3 Timur. The observed variables that were observed were: main variables: soil erodibility value and supporting variables: soil texture, soil structure, soil permeability, and organic matter. All data obtained, either directly or indirectly, will be presented in tabulative and graphic form as well as descriptive reports and soil erodibility values can be calculated using K-USLE. The value of soil erodibility with quantitative numbers on reclaimed land aged 3 years (0.45) shows a rather high criteria, reclaimed land aged 5 years (0.31) shows moderate criteria and reclaimed land aged 10 years (0.22) shows moderate criteria While the soil erodibility with a effective number on forest land (0.13) shows low criteria.
