Abstract

Abstract. Based on the overburden stripping production data at Pit 3 East, Electrification Mining Work Unit Shovel and Truck of PT. Bukit Asam Tbk. June 2019 for 4 mining fleet, are around 994.792,50 Bcm. From the actual production above, it is known that the overburden stripping production target for 4 mining fleet is 1.300.000 Bcm, so it can be concluded that the overburden stripping production target in June 2019 is not reached. Based on the data from mining equipment working hours, a percentage of consecutive utilization of available working time of the EU (Effective Utilization) for 4 mining fleet is 26.28%; 58.03%; 57.21% and 60.38%. From these problems, the percentage of utilization of available working time EU (Effective Utilization) cannot be utilized optimally. From the problems above, it is necessary to analyze the optimal losstime to fulfill the overburden stripping production target. As for, the analysis that will be used in this study is multiple linear regression analysis which is using the least squared method in estimating the coefficient of multiple linear regression. The purpose of the analysis is to obtain an optimal losstime mathematical model in fulfilling the overburden stripping production target in June 2019.Keywords: Produksi, Losstime, Waktu Optimal, Analisis Regresi Linear Berganda, Least Squared

Abstract

The purpose of this study was to determine the physical condition of Brandon fc players before nd during the new normal. This research is descriptive research. The population in this study were ll football players Brandon fc. The sampling technique used total sampling, the number of samples was 18 people. data nalysis techniques in this study using percentage techniques. The results of the study: (1) The dominant leg muscle power of the Brandon fc player when new normal was 9 people, including the good category. (2) The dominant endurance of Brandon FC players t the time of new normal is 11 people, including the moderate category. (3) The dominant right gility owned by Brandon FC players is 16 people in the good category nd 10 people in the poor category. There is no significant decrease in the explosive power of the leg muscles of the player because the independent training program provided by the coach is carried out seriously by the player.
