The mining industry is vital in securing Indonesia’s energy security and economic growth. Within these facilities there exist many pieces of equipment that require maintenance. To ensure the safety, operational performance, and cost-effectiveness of this facility, proper maintenance management is crucial, one of them being Reliability Centered Maintenance (RCM), which is used due to its comprehensive and detailed approach to improving the maintenance strategy tasks. However, the reference documents for traditional RCM are highly outdated. For this reason, the objective of this paper is to analyze the maintenance strategy using an optimized version of RCM, which is Reliability Centered Maintenance – Reengineered ® (RCM-R). This version is more structured and complete, including analysis from Asset Criticality Analysis, FMEA, RAM, and Weibull Distributions through a 10-step process. By doing so, this paper optimizes PTFI’s maintenance strategy for their Ball Mill equipment using industrial data, which includes reviewing the existing preventive maintenance (PM) task list. The results of this paper reveal that 8 of the existing PM tasks must be modified, which allows a target reduction in total maintenance time by 14.07%. This gives PTFI a target of 1.59% increase in availability per year, which is equivalent to a potential profit increase estimate of around Rp. 96.9 billion, or $6.0 million annually.
