Abstract
PT. Cipta Kridatama merupakan kontraktor yang bergerak pada bidang jasa penambangan yang berlokasi di Desa Makarti, Kecamatan Marangkayu, Kabupaten Kutai Kartanegara, Propinsi Kalimantan Timur. Sistem penambangan yang digunakan adalah sistem tambang terbuka dan metode yang digunakan adalah Strip Mine. Pemakaian bahan bakar alat angkut yang digunakan perusahaan pada front penambangan Liebherr R9250 (CE221) bulan April 134.190 liter sedangkan bulan Mei 143.134 liter dan pada front penambangan Liebherr R9250 (CE179) bulan April 114.380 liter sedangkan bulan Mei 152.823 liter. Permasalahannya terjadi adalah karena kenaikan konsumsi bahan bakar pada bulan mei dibandingkan bulan april. Upaya untuk mengurangi konsumsi bahan bakar dengan cara memperbaiki pola pemuatan, merawat kondisi jalan angkut waktu musim hujan maupun kemarau, memperlebar lebar jalan angkut sesuai standar, sehingga dapat dilewati alat angkut dengan lancar. Lebar jalan angkut yang tidak mencapai standar diperlebar minimal sesuai dengan standar. Oleh karena itu dengan berkurangnya kendala dilapangan dan lebar jalan angkut sesuai standar maka cycle time lebih kecil kecepatan lebih tinggi dapat mengurangi konsumsi bahan bakar. Cycle time berhubungan dengan kecepatan yaitu 16,7 mph dan 11,7 mph maka terjadi pemakaian bahan bakar berdasarkan putaran mesin 504,27 liter/menit dan 711,90 liter/menit. Kemiringan jalan pada yang memungkinkan untuk dilakukan penurunan ada pada lokasi front CE 221 segment jalan 5 dan 6 menjadi satu segment 5 dengan penurunan sebesar 3,19% terjadi penghematan konsumsi bahan bakar sebanyak 15,98 liter/hari. Pada lokasi front CE 179 segment jalan 7 dan 8 menjadi satu segment 7 dengan penurunan grade sebesar 1,89% terjadi penurunan konsumsi bahan bakar sebanyak 3,56 liter/hari. PT Cipta Kridatama was the contractor that moves on the field of service mining which was located in the village of Makarti, district Marangkayu, Kutai Kartanegara Regency, East Kalimantan Province. The mining system used is an open mine system and method used is strip mine. The usage of fuel transport equipment used on the company is diesel fuel. In mining front of Liebherr R9250 (CE221) April 134,190 litre whereas in May 143,134 litres. In mining front of Liebherr R9250 (CE179) April 114,380 liters while the month of May with a total of 152,823 litres. The problem occurs is due to the increase in fuel consumption in May compared to april. Efforts to reduce fuel consumption by improving loading pattern reducing transport time road conditions of the rainy season and the dry season, widened the road transport width according to the standard, so it can be passed smoothly transport tool. Road transport width does not reach the minimum standard was extended in accordance with the standards. Therefore with the real constraints and reduced the width of the road transport standards then the cycle time is smaller at higher speeds could reduce fuel consumption. Cycle time is related to the speed of 16.7 mph and 11.7 mph then it happened based on fuel consumption engine round 504,27 liters/minute and 711,9 liters/minute. The slope of the road on which allows to do a decrease on the location front CE 221 segment road 5 and 6 with a decrease of 1% decline as much fuel consumption 23,84 litres/day. On the location front CE 179 segment Road 1, 2, 10, 14, and 17 with the declining grade of 1% fuel consumption decline by as much as 29 litres/day. Slope road on the possible to do the decline is on location front CE 221 segment road 5 and 6 into one segment 5 with decrease by 3,19% occurring thirft consumption fuel as many as 15,98 liters/day. On the location front CE 179 segment road 7 and 8 into one segment 7 with declining grade of 1,89% consumtion decline in fuel as many as 3,56 liters/day
