Abstract

PT. XYZ is a company which is concerned in the manufacture of air conditioning. The problem with the current layout is that each interconnected area has a great distance, and there are backtracking, cross-movement, and does not have one flow process. The problem makes the time of this fabrication process to be long or less effective and due to the distance between the distant areas, causing the distance of material handling moves that are less effective. The long distances can affect the timing of product displacement and the cost of material handling. In this research, the design is created an ergonomic design for the table in the housing area with the aim of increasing the optimality of the fabrication process in PT. XYZ and redesign the layout of each area using the CORELAP Method. The CORELAP Method consists of three stages: the analysis phase, the adjustment stage, and the evaluation stage. The analysis phase includes material flow analysis, Activity Relationship Chart (ARC) analysis, and the space of the available area. The adjustment stage is the stage to arrange the layout of proposed results from the CORELAP Method and adapt to the needs or circumstances of the field. The last stage is the evaluation stage, which is to compare the actual layout and the proposed layout. CORELAP Method is adapted to the needs and conditions in the field to produce the optimal layout that has one flow process of the fabrication process and save the material handling cost of Rp877.622,31 or save material handling cost of 62,53% compared to the actual layout.
