Abstract

PT. Indonesia Power UJP Central Java 2 Adipala is a 1 x 660 MW steam power plant with coal as its main fuel. Distribution of coal using Belt Conveyor 1 AB, 2 AB, 7 to the coal yard. The background of the problem is the process of releasing idlers on conveyors 1AB, 2AB, 7 takes a long time of 7 minutes 54 seconds. Idler replacement is done in the conventional way by hitting the idler with a hammer until it is released from the conveyor frame. The cause of the problem is the rust of the idler shaft on the conveyor frame and the process of releasing the idler in the conventional way. The impact of the problem is the conventional replacement of idlers making coal dust fly so that coal dust enters the respiratory system and the eyes and much. In addition, conveyor production time is lost due to a long replacement. The purpose of this research is to design an Idler lifter tool to accelerate the carrying idler release time on the conveyor. The research solution is to design an Idler lifter with a Hydraulic jack mechanism to lift the idler from the conveyor so that the idler release time can be reduced and does not make coal dust fly. Confirm solution was the result of research which included reducing idler release time by 3 minutes 49 seconds or reducing replacement time by 51.687% so that the amount of coal distributed was more than 62,553,859 tons and human labor was reduced by 90,744% in sloping position and 89.31% in flat position using the Idler lifter tool
