Arsa Mulia Sukses (AMS) is a mining company engaged in limestone mining using the quarry mining method. The research location is in pit I, Padabeunghar Village, Cibuntu District, Sukabumi Regency, West Java Province. Based on field observations, research was carried out on production activities with the aim of knowing the consumption and fuel ratio of the digger and hauling equipment, analyzing the factors that influence fuel consumption and optimizing the consumption and fuel ratio of the digging and hauling equipment. Mining activities are carried out using a combination of Caterpillar CAT 320GC Excavators, Doosan DX 225LCA and Mitsubishi Fuso 220PS 4×2 haulers. Based on the results of research in the field, the condition of the haul roads that are not in accordance with the standards include; the road is not wide enough, the slope of the road (Grade) and the condition of the haul road surface which is stagnant and muddy which results in increased fuel consumption. This study uses field observation methods and data collection in the field such as cycle time and work efficiency of excavation and hauling equipment, avoidable and unavoidable obstacle times, haul road width, road grade and subsidence, actual working hours, actual fuel consumption and actual fuel ratio. The ratio between fuel consumption and productivity is called the fuel ratio. PT. Arsa Mulia Sukses has fuel consumption for the Caterpillar CAT 320GC loader which is 45 liters/day, the Doosan DX 225LCA which is 47 liters/day and the Mitsubishi Fuso 220PS transporter which is 20 liters/day, with a standard fuel ratio of 0.11 liters/BCM for the excavator and 0.18 liters/BCM for the conveyance. The actual productivity of the Caterpillar CAT 320GC was 51.20 BCM/hour with a fuel consumption of 6.92 liters/hour, the actual productivity of the Doosan DX 225LCA was 74.29 BCM/hour with a fuel consumption of 7.22 liters/hour and the actual productivity of the Mitsubishi Fuso 220PS was 122.85 BCM/hour with a fuel consumption of 27.88 liters/hour and the actual fuel ratio value for Caterpillar C was obtained. The AT 320GC is 0.14 liter/BCM, the actual fuel ratio for Doosan DX 225LCA is 0.10 liter/BCM and the actual fuel ratio for Mitsubishi Fuso is 0.23 liter/BCM. This shows that the actual fuel ratio is greater than the company's standards, namely 0.11 liters/BCM for digging equipment and 0.18 liters/BCM for hauling equipment. After improving the fuel ratio value, the productivity of the Caterpillar Cat 320 GC rig is 54.87 BCM/hour with a fuel consumption of 6.45 liters/hour, the productivity of the Doosan DX 225LCA is 79.62 BCM/hour with a fuel consumption of 6.74 liters/hour and the productivity of the Mitsubishi Fuso 220PS is 14.63 BCM/hour with a fuel consumption of 2.89 liters/hour. So that the fuel ratio value of the Caterpillar CAT 320GC loader is 0.12 liters/BCM, the fuel ratio for Doosan DX 225LCA is 0.08 liters/BCM and the fuel ratio value for the transportation equipment is 0.20 liters/BCM = PT. Arsa Mulia Sukses (AMS) merupakan perusahaan pertambangan yang bergerak di penambangan batu gamping dengan metode penambangan quarry, Lokasi penelitian berada pada pit I, Desa Padabeunghar, Kecamatan Cibuntu, Kabupaten Sukabumi, Provinsi Jawa Barat. Berdasarkan pengamatan dilapangan dilakukan penelitian pada kegiatan produksi yang bertujuan untuk mengetahui konsumsi dan rasio bahan bakar alat gali muat dan alat angkut, menganalisis faktorfaktor yang mempengaruhi konsumsi bahan bakar dan mengoptimalkan konsumsi dan rasio bahan bakar alat gali muat dan alat angkut. Kegiatan penambangan dilakukan menggunakan kombinasi alat gali muat Excavator Caterpillar CAT 320GC, Doosan DX 225LCA dan alat angkut Mitsubishi Fuso 220PS 4×2. Berdasarkan hasil penelitian di lapangan, kondisi jalan angkut yang tidak sesuai dengan standar diantara; jalan kurang lebar, kemiringan jalan (Grade) dan kondisi permukaan jalan angkut yang tergenang dan berlumpur yang mengakibatkan dari konsumsi bahan bakar meningkat. Penelitian ini menggunakan metode pengamatan lapangan dan pengambilan data di lapangan seperti cycle time dan efisiensi kerja alat gali muat dan alat angkut, waktu hambatan baik itu yang dapat dihindari maupun tidak dapat dihindari, lebar jalan angkut, grade jalan dan amblasan, jam kerja aktual, fuel consumption aktual dan fuel ratio aktual. Perbandingan antara konsumsi bahan bakar dengan produktivitas disebut fuel ratio. PT. Arsa Mulia Sukses memiliki konsumsi bahan bakar (fuel consumption) untuk alat gali muat Caterpillar CAT 320GC yaitu 45 liter/hari, Doosan DX 225LCA yaitu 47 liter/hari dan alat angkut Mitsubishi Fuso 220PS yaitu 20 liter/hari, dengan standar fuel ratio 0,11 liter/BCM untuk alat gali muat dan 0,18 liter/BCM untuk alat angkut. Produktivitas aktual Caterpillar CAT 320GC didapatkan sebesar 51,20 BCM/jam dengan fuel consumption sebesar 6,92 liter/jam, produktivitas aktual Doosan DX 225LCA sebesar 74,29 BCM/jam dengan fuel consumption sebesar 7,22 liter/jam dan produktivitas aktual Mitsubishi Fuso 220PS sebesar 122,85 BCM/jam dengan fuel consumption sebesar 27,88 liter/jam dan didapatkan nilai fuel ratio aktual Caterpillar CAT 320GC sebesar 0,14 liter/BCM, fuel ratio aktual Doosan DX 225LCA sebesar 0,10 liter/BCM dan fuel ratio aktual Mitsubishi Fuso sebesar 0,23 liter/BCM. Hal ini menunjukkan bahwa fuel ratio aktual lebih besar dari standar perusahaan yaitu 0,11 liter/BCM untuk alat gali muat dan 0,18 liter/BCM untuk alat angkut. Setelah dilakukan perbaikan nilai fuel ratio didapatkan produktivitas alat gali muat Caterpillar Cat 320 GC sebesar 54,87 BCM/jam dengan fuel consumption sebesar 6,45 liter/jam, produktivitas Doosan DX 225LCA sebesar 79,62 BCM/jam dengan fuel consumption sebesar 6,74 liter/jam dan produktivitas alat angkut Mitsubishi Fuso 220PS sebesar 14,63 BCM/jam dengan fuel consumption sebesar 2,89 liter/jam. Sehingga didapatkan nilai fuel ratio alat gali muat Caterpillar CAT 320GC sebesar 0,12 liter/BCM, fuel ratio Doosan DX 225LCA sebesar 0,08 liter/BCM dan nilai fuel ratio alat angkut sebesar 0,20 liter/BCM.
