Evaluation of the Result Rate of Reclamation with 5 Years-Old Revegetation on Post-Coal Mining Land in Lati Site Pt.Berau Coal

Mining activities with open mining system give changes in the landscape and generate other negative impacts on the environment. Therefore, the post-mining land treatment is necessary taken to restore the condition of the mine site. One of the efforts that can be done is reclamation and revegetation. The purpose of this study was to assess and evaluate the success rate of reclamation and revegetation in coal postmining fields at PT. Berau Coal. This study was carried out on PT Berau Coal revegetation land in Lati Site, Sembakungan Village, Gunung Tabur District, Berau Regency, East Kalimantan. This field work was conducted for two months. This study adopted survey, sampling and scoring methods. Revegetation plants used are revegetation with planting age 5 years old. Assessment of revegetation criteria was accomplished by a sampling system using sample plots. The first sample plot was obtained by random sampling, then the next plot was systematically determined with a zig-zag pattern. The results of the study showed that the land management criteria had a score of 30, erosion and sedimentation control was 13 and revegetation was 47.3. The success rate value of reclamation with revegetation is included in the good and successful category with an evaluation value of 90.33%.
