Abstract

Based on Law no. 3 of 2020 article 140 concerning Mineral and Coal Mining which states that "Every holder of a Mining Business Permit (IUP) and Special Mining Business Permit (IUPK) is required to submit a reclamation plan and post-mining plan when applying for a Production Operation IUP or Production Operation IUPK as basis for placing reclamation guarantees. The aim of this research is to calculate the direct and indirect costs required for PT Bukit Asam's reclamation plan. The research method used in this research is using activities in the form of visits and direct observations in the field and also collecting articles as support. Direct costs include recountouring costs, revegetation costs and maintenance costs, which are planned at Rp. 12,889,010,229. Meanwhile for indirect costs, the amount is determined from the indirect cost graph, the plan is Rp. 3,054,695,424, so the total cost of the reclamation plan for the West Banko Pit is Rp. 15,943. ,705,653 with an escalation calculation of 5.51%, it becomes IDR 19,758,945,354.

Abstract

PT Bukit Asam is one of the companies engaged in the coal mining sector which is located in Tanjung Enim, South Sematra. The mining system applied in exploiting coal is open pit mining which produces water called acid mine water (AAT), one of the components of the AAT problem. namely total suspended solid (TSS). At PT Bukit Asam, Bangko Barat, there are several KPLs that are still in use. KPLs that are continuously supplied with mining water certainly produce a negative impact, namely silting. The aim of this research is to analyze the cost of dewatering sedimentation in mud settling ponds. The method used in this research is to use field visits and direct observations. The shallowing itself is caused by rain factors and the long deposition time. To prevent silting, draining is carried out using an excavator and loading of the material using a dump truck. Draining activities in February amounted to IDR 185,634,400.00 handling the mud settling ponds also using chemicals or control methods which are useful for settling mud particles so that the draining process at the KPL runs quickly.
