Therefore, all machines have to be in the best condition as it can be. These machine should be maintained optimally so all production goals could be achieved with the minimum cost of maintenance. This study will use Reliability-Centered Maintenance (RCM) method to get the right preventive task and time interval for maintenance and Risk- Based Maintenance (RBM) method to find the risk value related to the economic aspect of the company. The output of the RCM method would be 18 Scheduled Discard Task and 6 Scheduled Condition Task for the subsystem machine and the time interval of the repair will be different depending on the type of tasks and components. The repair cost for preventive maintenance task in a year is IDR 2.029.266.063. By implementing the RBM method, the risk value will be IDR 269.768.775 if the company is not doing the preventive task proposed in this study.
