The end result of a product is accepted by the consumer, sold and sold. One way for the product to be accepted by the consumer is an attractive appearance that is by painting. in large-scale production of painting process with semi automatic and even automatic equipment. Painting line is a set of painting appliances that operate automatically. To be optimally required periodic maintenance. In this study calculated RCM (Reabilty Cost Maintenance) of unscheduled care with the scheduled. Preparation of preventive maintenance schedule based on RCM assessment on the painting line machine can increase the value of MTBF (Mean Time Between Failures) so as to increase reliability, reduce defective product by 75%, save the cost of Rp 15,616,224,000 per year, reduce the time to repair up to 95% so that machine can operate optimally and help improve company productivity.
