Abstract

Coal mining activities often cause negative impacts, especially on the environment, such as decreased land productivity and increased soil density. Mining activities that result in a decrease in productivity and change the soil structure on post-mining land have a great opportunity for erosion because damaged soil conditions cause the soil to become sensitive to erosion. A reclamation effort is needed on coal post-mining land such as revegetation. Eucalyptus (Melaleuca cajuputih) is one type of vegetation planted on PT Bukit Asam, tbk post mining reclamation land. The purpose of this study was to determine the effect of different ages of eucalyptus plants on soil erodibility values on revegetated land after coal mining at PT Bukit Asam, Tbk IUP Banko Barat and the distribution map of soil erodibility values on revegetated land after coal mining at PT Bukit Asam, Tbk IUP Banko Barat. The research method used is a semi detailed survey method with data analysis carried out using a quantitative approach, namely data processed by statistical testing using the T-test from the results of data collection by purposive sampling. The results showed that the soil erodibility value at each age difference of eucalyptus (Melaleuca cajuputih) plants in Coal Post Mining land at PT Bukit Asam, tbk showed a significant difference. The highest average erodibility value is on the one year old eucalyptus plant revegetation land Banko 2021, the erodibility value tends to decrease with the increasing age of eucalyptus plants (Melaleuca cajuputih). Based on the classification of soil erodibility levels, one-year old eucalyptus plants on revegetated land, namely Banko 2021, are included in the high category, Banko 2019 with three years of eucalyptus plant age is included in the medium category, and Banko 2017 with five years of eucalyptus plant age is included in the medium category.
