From the data obtained, production costs of overburden stripping will be found. From the result of the research, the productivity of digging-loading tool Shovel Komatsu PC 3000 is 802.05 bcm/h and the productivity of hauling tool Rigid Truck Belaz is 116.72 bcm/h. Fixed cost of digging-loading tool is 2,577,801 IDR/h that consists of depreciation cost is 2,277,433 IDR/h and costs of interest, tax, and insurance are 300,368 IDR/h.
