Track: Reliability and Maintenance Management/Engineering

Abstract

In Indonesia, one of the most important energy sources is coal. Since 2020, Indonesia's coal production has increased. This is partly due to the energy crisis in Europe. As production increases, mining companies need better equipment. To achieve production targets, reliability and availability are the most important factors. One of the factors that have an impact on mining equipment reliability is preventive maintenance. Preventive maintenance (PM) is intended to reduce the probability of failure or degradation of functioning of an item and is carried out at predetermined intervals.  Maintenance performance measurement is therefore essential to ensure that maintenance objectives are achieved, and that maintenance adds value for the company. This research aims to understand preventive maintenance applied by coal mining actors in Indonesia. Questionnaire is used to collect opinions of maintenance crew about their experience in conducting preventive maintenance. It is then summarized to get preventive maintenance characteristics in Indonesian coal mining contracting company.
