Abstract

PT Asyatek Indonesia is a company engaged in manufacturing with production results, namely drums and vessel. One of the machines used is Three Roll Bending Machine that have the biggest downtime. The purpose of this research were to identify the damage in Six Big Losses, component and system reliability, downtime when preventive maintenance, preventive maintenance time to improve the reliability of 85%, and maintenance costs. Data obtained using the method of RBD (Reliability Block Diagram), and simulated to get the lowest maintenance costs. In the identification of Six Big Losses all components machine include category of Downtime Losses. The results showed that the highest component amounted to 29% of total downtime, is Coupling Components. Reliability of Panel Control 42%, Gear Box 43%, Hidraulic 34%, Grase Holder 44%, Fan Belt 46%, Motor 41%, Coupling 45%, Pneumatic 30% and Lock 37%. The value of RBD first system is 61%. The value of the downtime when preventive maintenance occurs is 6445 minutes. Proposed schedule of preventive maintenance to increase 85% reliability so that the Control Panel components 33 days, the Gear Box for 30 days, Hidraulic amounted for 40 days, Grase Holder for 40 days, the Fan Belt 35 days, Motor 40 days,Coupling 20 days, Pneumatic 38 days and Lock l35 days. Corrective maintenance cost of Rp 14,102,000 and preventive maintenance cost Rp 12,988,917. Keywords : Maintenance Costs, Downtime, Preventiive Maintenance, RBD
