Overburden loading activities use Liebherr 9200 with actual production of 721.43 BCM/hour while production target of 800 BCM/hour, transportation using Komatsu HD 785 with 720.56 BCM/hour while production target of 800 BCM/hour, and actual fuel ratio of 0.28 liters/BCM while the fuel ratio target is 0.20 liters/BCM, because it has not reached the fuel ratio target company, it is necessary to conduct an analysis of the effect of fuel consumption. One of the factors that affect fuel consumption is the condition of the road geometry. For this reason, it is necessary to carry out an analysis to increase the production of transportation equipment with appropriate fuel consumption. The purpose of this study is to determine the condition of road geometry, production of mechanical devices, average fuel consumption, and fuel ratio value. Road geometry analysis is guided by the theory of AASHTO (American Association of State Highway and Transportation Officials) by observing the width of the road in straight conditions, the width of the road in bend conditions, and the slope of the road, which is 12%, in addition to the required data on fuel consumption, distribution time, obstacle time, filling factor, and development factors. These results will get the travel time and speed needed to be compared with fuel consumption, so companies must analyze the effect of road geometry on fuel consumption to improve production results so that the fuel ratio target can be achieved. The geometry of the road in the study area such as the road width in the straight conditions of segments A-B, C-D, D-E, E-F, F-G, and I-J while the road width in the bend conditions of segments A-B, D-E, F-G, H-I, J-K, and M-N, the slope of the road in the F-G segment is 14.22% still not in accordance with AASHTO standards so it is necessary to make improvements. The production of transportation equipment repairs amounted to 980.48 BCM/hour, so that the production target was achieved. The average fuel consumption of the loading device is 51.2 liters/hour. The fuel ratio value after repair was obtained at 0.20 liters/BCM. Abstrak.
