Perencanaan Teknis dan Biaya Reklamasi Lahan Bekas Penambangan Batubara Pit 1 di PT Seluma Prima Coal, Desa Rangkiling, Kecamatan Mandiangin, Kabupaten Sarolangun, Provinsi Jambi

Coal is a fossil fuel derived from sedimentary rocks that can be burned and formed from organic deposits and formed through the coalification process. One of the open pit coal mining methods applied by mining companies in Indonesia is the open pit method. After mining activities in a pit are completed, the ex- mining land will leave openings. The openings are backfilled with material from the overburden in the pits that are mined next.. This study uses quantitative, descriptive, and interviews with the company. The use of this method, because in the future research will use data in the form of numbers and present data in a visual form that is processed from data modeling so that it is easy to understand. The planned reclamation area is pit 1 opening area. The total area of the plan for reclamation of former coal mining pit 1 is 11.43 Ha, with an area for revegetation that is 9.13 Ha, and the area for other uses is 2.3 Ha (roads and trench). In the implementation of reclamation activities, it is inseparable from the design of the reclamation plan and the calculation of the reclamation cost plan. The design for the reclamation of pit 1 was made using a topographic map of the research area and a map of the mine situation. The reclamation design carried out includes road geometry with a straight road width of 9 m, a bend road width of 16 m, and a road grade of 8% (4.6o); level geometry with a ladder angle of 45°, an overall angle of 13°, a width of 5 meters, and a height of 6 meters; the terrace design used is a garden terrace with a terrace width of ± 1.5 m; and ditch construction with a width of 0.5 meters and a depth of 1 meter. The cost of the reclamation plan in the form of revegetation pit 1 to reclaim a land area of 9.13 hectares is Rp. 647,486,722 (six hundred forty- seven million four hundred and eighty-six thousand seven hundred and twenty-two rupiah). This cost includes the cost of land management, revegetation, and maintenance for 3 years.Keywords: Reclamation, coal, cos
