Abstract
PT. Budi Gema Gempita is a coal mining company located in Lahat Regency, South Sumatra Province. The open pit mining method is carried out by strip mining with a combination of shovels and trucks. The production targets for coal and overburden Pit LDA in January 2021 were 81,274 tons and 267,519 BCM, however the planned production targets were not achieved. The realization of coal production was 61,866 tons or about 76% and for overburden was 214,177 BCM or about 80%. Not achieving the production target needs to be minimized by evaluating the planned mining production target. This study compares the calculation of real production in the field and theoretical production. This study aims to analyze why production inadequacy occurs, factors causing inadequate production, seek efforts to minimize production inadequacy and forecast production in 2021. The results show that the inadequacy of coal and overburden production targets is caused by the realization of the fleet, the productivity of the digging equipment, the front distance mining, effective working time, less than optimal mechanical availability and supervision. Therefore, it must be rescheduled so that coal production increases by 21% and for overburden production increases by 10% and optimizes supervision. The production obtained from forecasting in 2021 is 1,006,281 tons of coal and 3,403,312 BCM for overburden with a stripping ratio of 3.38
