Abstract
PT. Tambang Bukit Tambi is one of the private companies engaged in coal mining located in Padang Kelapo Village, Moro Sebu Ulu District, Batang Hari Regency, Jambi Province. In coal mining activities using 2 fleets of excavators Komatsu PC400LC-8 and Dump Truck Hino FM 260 JD, Nissan CWM 330 PS and Nissan CWA 260 X. Research methods used to obtain data - data is quantitative method. The company's production target of 50,000 tons/month was not reached. The combination of tools in fleet 1 has a match factor value of 0.78 while fleet 2 is 0.82. Operating costs incurred today amount to Rp 27,047 /bcm. Fuel usage can be optimized using Mixed Integer Linear Programming (MILP) method, on fleet 1 by 27% and fleet 2 by 36%. In this study, effective working time improvement, swing angle and cycle time Dump Truck were conducted. Thus, after the improvement, there is no excess financing of operational costs in coal mining activities.
