Abstract

PT. Bima Putra Abadi Citranusa is a coal mining company that is part of Bomba Group, located in Lahat Regency, South Sumatra Province. Results of company's coal production are stored in stockpile. Problem that occurs in this company is stockpile management that has not been going well due to high coal in that exceeds coal out, so there is coal final stock and it can cause difficulty in implementing FIFO system. This problem is resolved through a study which aims to evaluate percentage of coal out management on coal in, analyze factors that affect stockpile management, and analyze efforts to improve stockpile management. Research method used is to combine theory with data taken from direct field observations. Results of this study showed that percentage of coal out on coal in was 87% with coal in was 226,238.82 mt and coal out was 176,959.89 mt. In December 2020 - February 2021, planned coal in is 405,175.42 mt and coal out is 316,036.83 mt. In February 2021 there is a plan for coal final stock of 138,417.52 mt to exceed stockpile capacity of 105,992.80 mt. Coal final stock can be stored in stockpile by improving capacity through dimensions of stockpile. After being repaired, dimensions of stockpile in form of truncated pyramid have length and width of 155.24 m and 88.10 m, respectively, with height of 10 m, angle of 38° and loose density of 1.29 ton/m3. Actual condition of stockpile has difference in length where previously it was 121.24 m.
