Production target of 68 181 LCM stripping OB / month, so that production targets overburden per hour was 340.9 LCM / hour. Production equipment Kobelco SK 330 excavator loading is 272.2 LCM / hour, the amount needed 2 units bringing the total production to 544.44 at LCM / hour. Jumbo DT production Hino Ranger is 53.74 LCM / hour, so the backhoe and truck production system is 376.18 LCM / hour, the amount of the required 7 units and in total production amounted to 376.18 LCM / hour is a little higher than production targets set by the OB company. MF value amounting to 0.69, because the value of MF <1 then FK = 0.69, means of transportation and unloading equipment is always busy and there is time to wait.
