Abstract
The need for continuous use of the machine will result in its reliability decreasing. Therefore, it is essential to support a machine's reliability in order to enable the production system to operate smoothly and fulfill its production needs. The fundamental problem of this study is in PT Gunawan Dianjaya Steel Tbk with with the Roll Table 5Q machine, which frequently experiences sudden damage caused by critical components. The goal of the study was to determine the maintenance time interval of the 5Q Roll Table machine, the optimal age of the machine, and the number of mechanics based on the minimum total maintenance cost in an effort to improve the reliability of the machine using the Reliability Centered Maintenance (RCM) II methods and Life Cycle Cost (LCC) methods. From the results of research for critical components As Roll Table obtained interval value of 331 hours / 13 days once a year with the selection of action is Scheduled restoration task and for Bearing components obtained interval value of 109 hours/5 days once a year with the selection of action is Scheduled on-condition task. From the calculation of the total life cycle cost of Rp. 3.858.937.289 with the optimal number of mechanics on the Roll Table machine as many as 3 mechanics with an efficiency level of 6,23% with an optimal age for the Roll Table machine 5Q is 12 years.
