Abstract

ABSTRAKTarget produksi batugamping PT. SinarTambang Arthalestari yaitu 8.876 ton/hari, nyata nya pada bulan Oktober hanya tercapai 319 ton/jam atau sekitar 4.309 ton/harihanyabarusetengahdari yang direncanakan. Maka dari itu perlu adanya penambahan pengumpanan sebanyak 340 ton/jam atau penambahan material sebanyak 17 kali tiap jamnya oleh dumptruck, sehingga akan tercapai target produksi yang direncanakan. Karena tingginya kadar air batugamping hasil dari front penambangan maka akan sering membuat crusher mati, ini merupakan salah satu hambatan yang mengakibatkan tidak tercapainya target produksi PT. Sinar Tambang Arthalestari, sehingga untuk mengurangi hambatan tersebut perlu juga dilakukan blending material pada saat dumptruck dumping di hopper dengan perbandingan 1:1:1:1 untuk setiap fron tpenambangan yaitu Sawangan Barat, Sawangan Timur, Undip Atas, danUndip Bawah agar mendapatkan kadar air yang relative lebih rendah atau dibawah 7% sehingga dapat meningkatkan produksi batugamping yang dari 319 ton/jam menjadi 340 ton/jam.

Abstract

AbstractPT. Adaro Indonesia is a coal mining company in Indonesia which implements Pit Crushing and Conveying (PCC) for overburden removal. The implementation of the PCC due to overburden removal combines shovel and truck, crusher, and conveyor in the operating system. Trucks are needed as a supplier of overburden to pit crusher station of the PCC. By implementing this system, there has been a difference (deviation) between the value of overburden supplied by truck and the value of overburden received (detected) by PCC. Based on the issue, an analysis is needed to minimize the deviation and to determine the accuracy of deviation supply of truck and PCC. This research was conducted to solve the problem by observing and analysing the factors that cause the difference (deviation) of the overburden supply value. The results of this research defines that the value of overburden received (detected) by PCC is generally higher than the value of overburden supplied by truck with a deviation in the range of 11% to 37%. The deviation can be minimized by using the density value corresponding to the overburden, by changing the calculation method of truck production and PCC production, and by establishing the accuracy deviation supply to truck and PCC.
