Abstract

The grade or slope of the road in a mining activity is certainly unavoidable. In addition to naturally following topographical contours, the shape of the mining pit is carried out from a high elevation leading to the lowest elevation following the slope level and the continuity of the excavation material makes the road should be made sloping. The high or low value of the road grade in addition to affecting the speed and travel time required by the unit, of course, also affects the level of fuel consumption. PT. Pamapersada Nusantara uses a conveyance unit with the HD Komatsu 785-7 type to move overburden material. Based on the results of the analysis, in the loaded condition, grade 2% uses 0.45 liters of fuel, 5% grades 0.77 liters, 6% grades 0.89 liters, 8% grades 1.09 liters and grades . While in the unloaded condition, grade 2% uses 0.19 liters of fuel, 5% grades 0.35 liters, 6% grades 0.4 liters, 8% grades 0.47 liters and 9% grades 0. 52 liters.

Abstract

Research on the application of the OHS system is carried out with the aim of analyzing things in the application of K3. The research method uses a descriptive method in the form of a questionnaire. The results of the research questionnaire the highest percentage included in the strength (strenght) including the use of PPE 83.9% agreed that it was applied followed in an orderly manner, promotions and strategies and the application of K3 64.5% strongly agreed, the existence of PPE training that was applied 74.2% agree. The results of the weakness analysis (Weakness) that the highest percentage of the results of the questionnaire diagram are incomplete first aid facilities 80% agree, the workplace is not conducive, planning for implementing K3 strategies, providing emergency facilities for accidents 83.9%, periodic initial checks to employees 74.2% quite agree.

Abstract

The barriers on the activity causes losstime. The losstime of excavator that so high cause coal production targets not to be achieved. Therefore efforts are made to improve the losstime. The analysis of multiple linear regression multivariate is used as a problem solving approach, namely finding the maximum limit of idle time and delay time and formulating the optimal losstime. Based on observations of the idle time and delay time of two excavator units operating in the morning shift, the regression equation is obtained Y = 1832.782 – 95.134X1. The equation of optimal losstime is X2 = -0.8729X1 + 10.71. The simulation is carried out based on the average actual data, the maximum idle time limit of 6.67 hours and a delay time of 4.89 hours. For an idle time of 4.45 hours, it is expected that the delay time will not exceed 6.83 hours in order to achieve the production target. The causes of unfulfilled of production were include rain, landslides, breakdown units, slippery, operator needs and et cetera.

Abstract

This study aims to measure the overburden volume at Pit 3HWE, PT. Indominco Mandiri using Unmanned Aerial Vehicle (UAV) technology. The use of UAV for volume measurement offers a more efficient and accurate alternative compared to conventional methods. In this research, aerial images were captured using a UAV and processed with photogrammetry software to generate a digital surface model (DSM) and 3D maps. The overburden volume calculations were analyzed and compared with manual measurement data as a reference. The results indicate that UAV usage provides accurate results with higher time efficiency, making it a viable method for mining operations. Factors affecting the measurement results, such as weather conditions and image resolution, were also analyzed in this study.
