PT Varia Usaha Beton is a subsidiary of PT Semen Indonesia Beton which produces various kinds of concrete products located in Batang district. With the increasing demand for crushed stone production which is increasing every year, it is necessary to have equipment ready to support an optimal production process. Based on the results of the study, it is known that the average repair time or Mean Time To Repair (MTTR) on 4 critical conveyor belt machines, namely Portable 1 4.97 hours, Ground 2 2.5 hours, Portable 3 1.93 hours, and Return 2.1 hours. Meanwhile, the average value of the repair time interval until the unit is damaged again or Mean Time To Failure (MTTF) respectively is 111.9, 327.25, 321.40, 113.12 hours. Based on the results of the MTTR, Portable 1 was found to have the longest repair time, inversely proportional to Portable 3 which had less repair time on average than the 4 critical belt conveyor machines. Meanwhile, from the MTTF value, it is found that Ground 2 is the longest time interval from repair to damage again, inversely proportional to Portable 1.
