Abstract

Pt. Semen Baturaja TBK Persero is one of the state-owned companies engaged in the cement industry, since 1974 located in West Baturaja, Ogan Komering Ulu, South Sumatra Province. PT Semen Baturaja utilizes limestone as the main raw material in making cement by applying surface mining and blasting methods. every end of the mining activity must implement reclamation. one of the post mining activity plans by PT Semen Baturaja Tbk is to utilize voids as a micro hydro power plant. One of the parameters that must be met is the quality of water. The results of water sample testing indicate that the water content in the limestone mining area has a suspended solid content of 17-22 mg / L, with the metal content contained in the water still below the water quality standard. With a void area of 53.94 Ha, it is capability to storing of water, void in the area of the former limestone mining at PT Semen Baturaja has the potential as a source of water for micro-hydro power plants

Abstract

Limestone mining in PT Semen Baturaja mine mining materials in the form of limestone. Limestone is the material needed to make cement. Open mining activities at the final stage will leave ex-mining land. Ex-mine land in the PT Semen Baturaja reclamation area has been planned for revegetation of sengon seedlings. The research was conducted to examine economically post-mining land of limestone mines for sengon plantations. The initial baseline studied in the study area includes climate, space and geological conditions, and vegetation. Some plants in the study area include sengon, cypress, and guava. The results showed that the use of limestone quarry land for sengon plants had met economically. The results of the study are expected to be utilized by stakeholders, academics, practitioners, researchers, mining associations and the environment.
