Abstract

This study determines actual fuel ratio September and October, calculates cost wasteful fuel consumption, analyzes the factors fuel ratio, and recommends increasing production and fuel ratio efficiency. Primary data cycle time top loading and bottom loading Sany 365Hpro Excavator and Howo NX380 Dump Truck, secondary data fuel ratio plan, actual working hours, and fuel consumption in September and October. The actual fuel ratio value exceeds the fuel ratio plan September 0.508 liters/ton with difference 0.204 liters/ton and October 0.498 liters/ton with difference 0.115 liters/ton. Fuel costs Rp. 128,701,980 in September and Rp. 55,541,132 in October. Factors of the fuel ratio top loading or bottom loading, causing lost opportunities September 5168.25 MT/Month and October 5774.72 MT/Month. Use the same excavator coal cleaning and general activities causes lost time coal getting. Lose opportunity coal cleaning and general activity September 7278.99 MT and October 10115.98 MT. Top loading recommendations for coal getting resulted greater productivity. Using PC Komatsu 200 and shifting coal cleaning and general activity working hours to effective working hours increased production September 37063.03 MT and October 32605.08 MT. Fuel ratio decreased September 0.408 liters/ton with cost efficiency of Rp. 46,685,029.5, while October 0.344 liters/ton with cost efficiency of Rp. 55,541,132.

Abstract

PT Bina Sarana is a coal mining contractor located in Darmo village and Pulau Panggung village. Lawang Kidul district, Muara Enim regency, South Sumatera province. The calculation of overburden volume using survey and truck count method on May is a 16,394.177 BCM, percentage 11.57. The aim of this study is to determine the volume of overburden transported based on survey and truck count method, analyze the casual factor and reparation. This study use quantitative method, overburden production on June and July is 910,304.25 BCM and truck count is 975.984,86 BCM. The identification of problem conducted sampling test to know the casual capacity of vessel, CMT 96 is 23.26 BCM, CMT 106 is 25.30 BCM on June and CMT 96 is 23.21 BCM, CMT 106 is 24.87 BCM on July. The identification of problem used improving the calculation formula truck count, percentage routinely conducted sampling test to determine the actual capacity of vessel. The factor that influence of overburden volume known with survey and truck count method along June-July of 2024 are the discrepancy between actual load, the lack of bucket fill factor, the inaccurate of field survey data (inaccurate setting, tool centering, inaccuracy of detailed progress point). After the improvement, the result of overburden volume of truck count on June-July is 924,735.17 BCM, has a decrease in company’s calculation differences of 6.72 % to 1.5 % with the company determination 2.75 %.
