Machines Maintenance Interval on Filling Lithos Lubricant Production Line: A Case Study

Abstract

The growth of industry in Indonesia is fast enough to encourage industrial players to improve their production capability. One of the sectors that has continuous increase in demand is the lubrication sector. This research was conducted in a major lubricants company in Indonesia that has 16 hours of work to meet market needs. The production capability and capacity of the company are affected by its production resources, one of them is the machine. Current machine's reliability in the company is below 85%, hence it needs efficient maintenance activities to improve and maintain the machine's reliability. In this research, we develop a simulation model to determine the maintenance interval to achieve world class standard of machine reliability at minimum 85%. From the results of the analysis, we proposed three alternatives of maintenance activity. First, preventive maintenance with interval maintenance according to the results of the simulation. Second, preventive maintenance with maintenance interval of half day or twice a day in the break time and after workhours. Third, corrective maintenance. The criteria used in comparing the three alternatives are the machine reliability, maintenance cost, and production loss for doing the maintenance activity. Among the alternatives, the second alternative gave better reliability with the lower cost compared to the other two alternatives.
