Abstract. PT. Satria Bahana Sarana is a contracting company engaged in coal mining services located in Bangko Barat, Muara Enim Regency, South Sumatra Province. In August 2019, the overburden stripping production target was 1,095,000 bcm in which the realization of field production was 645,755 bcm which reached 59%. In the production calculation using the overall equipment effectiveness (OEE) method, the production value of 643,701.33 bcm is obtained with the effectiveness of each fleet of 34%, 44%, and 42% which have not reached the world OEE standard of 85%. Some of the causes of unattainable production targets are due to the many loss time in mechanical equipment that includes several factors such as system factors, human environment, and equipment. After making improvements to the loss time, a production calculation using the overall equipment effectiveness (OEE) method was found to increase production value to 1.097.696 bcm which met the overburden stripping production target in North Pit 1 in August of 1,095,000 bcm. And the effectiveness of mechanical equipment increased to 53%, 57%, and 44%.Keywords: Production, Loss Time, Overall Equipment Effectiveness, Excavator, Analysis Simple Linear Regression

Abstract. PT. Bhakti Karya Mandiri (PT. BKM) is a contractor company engaged in bauxite mining. In mining activities, the company uses mechanical tools, namely the Hino 500 FM 260 JD dump truck and the Kobelco SK 330 excavator. The use of these mechanical devices cannot be separated from the use of fuel. The actual consumption of fuel for transportation vehicles in the field in April 2019 was 14,632 liters / hour, this value exceeds the standard fuel consumption for transportation means of 13 liters / hour. One of the factors that affect fuel consumption is road conditions. In general, the maximum slope of roads that can be traversed properly by means of transportation, both up and down on hills, is 8% or 4.5˚. However, the reality in the field is that there are 14 road segments that exceed the maximum standard. Based on the calculation, the relationship between road slope and total resistance to fuel consumption when the dump truck is loaded is based on multiple regression analysis with the equation Y = 0.32412 + 0.01404 X1 + 0.00001851 X2. While the relationship between road slope and total resistance to fuel consumption when the dump truck is empty is based on multiple regression analysis with the equation Y = 0.089 + 0.00305 X1 + 0.00001983 X2.Keyword: Bauxite, Fuel Consumption, Total Resistance, Road Slope, Multiple Regression Analysis

Abstract. In mining activities, production is an activity that produces minerals. In coal mining activities, there are two production operations carried out, namely overburden production and coal production, which to produce this production mechanical equipment is used which plays an important role in supporting the success of the production process. In the use of these mechanical tools, it is necessary to do precise calculations so that the capabilities of the tools can be used optimally and have a high level of efficiency to achieve production targets. PT. Bara Prima Pratama implements an open pit mining system with coal being mined. The mining method used is the Conventional Mining method, which is a mining method using digging and loading equipment and transportation equipment. The company is trying to meet its production targets with the aim of being able to meet domestic and export demands. In the overburden stripping activity, PT. Bara Prima Pratama uses a combination of mechanical equipment, namely a Excavator Doosan DX 500 LCA HD and Dump Truck Hino 500. For the compatibility of the work of the digging and loading equipment, a Match Factor value of 0.776 is obtained, which means that the digging-loading tool works less than 100% and the conveyance works 100% so that there is waiting time for the digging and loading equipment. After analyzing the Match Factor, the value is 1.03 so that the matching fleet calculation results are appropriate and the same. There is no waiting time for loading and unloading equipment or transportation equipment.
