Abstract
. Coal is a natural resource that is used as an energy source. One of the companies engaged in the utilization of coal energy resources is PT Bukit Asam Tbk. PT Bukit Asam Tbk Tarahan Port Unit as a place for loading and unloading coal is equipped with a temporary coal storage area or stockpile. The condition and function of the drainage on the stockpile as well as the performance of the KPL in each stockpile unit greatly affect the sustainability of coal management. This study aims to evaluate the dimensions of the MPA used for the coal management process and analyze the causes of the formation of coal liquid waste that occurs in the stockpile. This research was conducted by literature study and field observation. Based on the research that has been carried out, the results obtained are (1) TSS over capacity in KPL 1, (2) Sediment deposits are quite a lot seen in the drainage channel at each stockpile, (3) KPL 1, 2, 3, and 4 experience overcapacity every time it occurs. Rainfall and (4) a long time of water release to the sea and less large runoff release. The condition of the KPL is due to the high sediment entering the KPL and the drainage, the absence of a barrier between the drainage and the stockpile area, the size of the KPL and drainage not being able to accommodate the discharge load and the formation of coal waste in the drainage and KPL due to runoff water carrying fine coal material so that drainage stockpile not working optimally. Based on the results of the study, it is necessary to procure a water pump, build stockpile barriers, increase drainage height, and reverse the KPL. Refunction of the drainage system, control basin, runoff distribution connecting channel, and what is technically very important is the addition of stockpile barriers to reduce coal waste entering the environment and prevent flooding at the stockpile location.
