PT Bukit Asam Tbk is a coal company located in South Sumatra. The province of South Sumatra saves considerable energy resources, one of which is coal which is located in PT Bukit Asam Tbk. The soil scattering method used at PT Bukit Asam Tbk is the blasting method. Blasting is one of the parameters that need to be analyzed to evaluate the productivity of the digging tool, besides that there are other parameters that affect the productivity of the digging tool, namely the digging cycle time and the work efficiency of the digging tool. This analysis needs to be carried out in line with the target data for the productivity of overburden stripping activities in Pit 2 West Bangko in June 2020 which did not reach the target, which was 1,679,034.52 BCM/month from the target of 2,000,000 BCM/month with an achievement percentage of 83, 95%. After analyzing based on the data obtained, the productivity of the digging tool in July 2020 was 1,769,183.15 BCM/Month and with an average cycle time of 29.33 seconds with a percentage value of about 88.45%. . And for the percentage of distribution of bolts that can be said to be boulder or > 100 cm by 3.45%, it means that it still meets the criteria for good fragmentation. The distribution of rock fragmentation after blasting does not have much influence on the productivity of the PC-3000 shovel digging tool. While the factors that affect productivity are the efficiency of the PC-3000 shovel digging tool from 66.33% to 76.75%, weather and front conditions, and lack of supervision, which exceeds company standards.
