Increasing the availability of unloading equipment in the port service industry through lean manufacture and kaizen approaches with the PDCA Cycle method

PT Krakatau Bandar Samudera is a company engaged in port services which one of its business units serves the unloading of cargo raw materials owned by PT Krakatau Posco using crane and conveyor facilities, in the process of service PT KBS experienced several problems including the availability of conveyors below the target, the dominant problem that occurred was the belt Tearing on the edge whose dominant root cause is the dumper adjuster is easily damaged and how to set the dumper is difficult so that with the cause of the problem causes the conveyor belt to become side travel so that the belt rubs against the conveyor and belt construction become torn at the edges. To overcome this problem, researchers use lean manufacture and kaizen approaches with the PDCA Cycle Step, the resulting solution is to change the dumper setting system from manual using block levels to using a hydraulic actuator system. After an improvement in availability, initially 95.5% increased by 2.1% to 97.6%. So that there are no more complaints from management and from customers related to the availability conveyor.
