Perencanaan Sistem Pemeliharaan Mesin Roller Head dengan Menggunakan Metode Reliability Centered Maintenance II (RCM II) (Studi Kasus di Departmen Maintenance PT. Bando Indonesia)

PT. Bando Indonesia is the company which produce conveyor belt. The company have two departments, v-belt department and conveyor belt department. Based on breakdown data from August 2015 to July 2016, conveyor belt department has higher breakdown percentage than v-belt department. Then, in conveyor belt department, Roller Head machine has highest breakdown frequency. Reliability Centered Maintenance II is one of methods which could use for maintenance act evaluation from each machine components. Implementation from Reliability Centered Maintenance II expected give better maintenance interval so the machine reliability could be better. Based on Critical Priority Number (CPN) score could see if there 5 critical components in roller head machine. The critical components with its CPN score are gear (32), conveyor transfer chain (25), bearing (24), screw (24), and main motor (24). Based on Logic Tree Analysis (LTA) for the 5 critical components, they need to give scheduled discard task activity. Then based on its fault characteristic analysis, the breakdown rate phase tends to increase significantly and need to replace. Based on calculation of maintenance interval time to minimize downtime and minimize maintenance cost (Tc) from each critical component results if maintenance cost each year could decrease Rp. 33.304.864 or 14,51% lower than existing condition
