PT. Krakatau Argo Logistics is a company that works in the field of multimodal transportation services that serve land, sea and air transportation. One of the work processes of PT. Krakatau Argo Logistics uses the Reach Stacker TEREX TFC 45 LX HC heavy equipment. The effectiveness of the heavy equipment is still not optimal, this is inseparable from the problems caused by the six big losses. This study uses the Overall Equipment Effectiveness (OEE) measurement method, analysis of Six Big Losses calculations and Fishbone Diagram to find existing problems and provide solutions to fix these problems. From the measurement results, the average OEE value of Reach Stacker is only 40.44% with an average availability rate of 91.58%, an average Performance Efficiency of 63.12% and an average Quality Rate of 69.55%. These results have not yet reached the company's OEE target of 85% with Availability Rate >90%, Performance Efficiency >95% and Quality Rate >99%. The biggest factors affecting its effectiveness are reduce speed losses on average 43.92%, Idling & Minor Stoppages average 35.63%, Rework losses average 12.66%, and breakdown losses average 5.13%. So that the proposal for improving the Reach Stacker maintenance system of PT. Krakatau Argo Logistics is the application of the TPM pillar, namely autonomous maintenance to reduce the problem of six big losses so that there is an increase in effectiveness and the ideal OEE can be achieved.
