In meeting the needs of cement raw materials of limestone, PT Semen Baturaja (Persero) Tbk do its own mining activities. Mining activities will have an impact on the surrounding environment. Positive impacts arising from mining activities such as increasing the income of the surrounding community, opening jobs, and so forth. Meanwhile, the negative impacts caused are the change in the natural order and the color of the earth, noise, air pollution, water quality degradation, and others. Changes in the natural order that will be generated after mining activities are completed, one of which is a mine hole (void). The climate in South Sumatra, this region is generally included in tropical regions. The geology of the Baturaja formation is generally included in the Palembang group, which has Tma, Qtk and Tmpm formations. Mining activities at the limestone quarry of PT. Semen Baturaja (Persero) Tbk., carried out in two ways, it was surface mining, and blasting activity. Freshwater fish aquaculture will be carried out to provide economic value and can be used as an indicator that the water contained in voids is not dangerous, and it’s still in a standard regulated by the government.

Limestone mining activities of PT Semen Baturaja Ogan Komering Ulu Regency Tbk South Sumatra Province is done in the open mining quarry mining mining with the system. Limestone is the primary raw material required in the manufacture of cement in PT semen baturaja Tbk. Mining activities in the quarry is open at the end of its activities, will leave the land mines. Land mines must be utilized in order to make the environment mining can function returns appropriate allocation. Utilization of land mines can be done for a variety of Evergreen plants such as designation, orchards, and others. Designation ex limestone mines of PT Semen Baturaja Tbk as contained in document his rope Post Plans, one of which is for Evergreen plants. Research conducted in the survey aims to assess, technically land use limestone mines of PT Semen Baturaja for Evergreen plants so that land mines can be used again, so that the negative effects of mining activities can be reduced. The results showed, the utilization of land of a former limestone to plant pine PT Semen baturaja has met the required technical aspect in planning post-war mine . Research results are expected to be of benefit to the stakeholders, academics, researchers, practitioners and the Association of mining, and the environment. Keywords: land use Plan, a former Post-war mines, technical aspects, Plant Evergreen

THE USAGE OF MINING VOID IN LIMESTONE MINING FOR MICRO HIDRO POWER PLAN IN PT. SEMEN BATURAJA (PERSERO) TBK Ahmad Suryantoko; Restu Juniah; Harminuke Eko Handayani

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

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.
