Improvement of Nut and Screw Placement in Warehouse with ABC Analysis
Keywords:
improvement placement in warehouse; ABC analysis method; Paired T-testAbstract
The aims of this study is to present key assumptions of management with particular focus to reducing time of raw material storage process and raw material prepare process of warehouse. This research is the practical action research which basically demonstrates the applicability of solving a series of immediate problem. In addition, the result of this study are applicable only within the scoped problem This study by using timing method. This study is developed on basis on a sample of incoming raw material placement process and removing raw material from the storage shelf. The research tool contain the SPSS statical program and timing clocks. The researcher designed the group sample by using the purposive sampling method. The results of this research emphasize the place where inbound raw materials which particularly designed by the researcher compared to the original proce before implement the placing adjustment by using the timing method, a total is 953 of inbound material, storage location and storage procedure. From collected timing results, the average time before implement is 21.67 seconds and after improvement process is 20.56 seconds. It was found that when material placement position changed according to the researcher’s designed, In particular, the result shows the one step ahead of good working time which can reduce 1.11 second. In order of the outbound raw materials from warehouse originally took 22.18 seconds of overall process. After the implementation of improvement program can consolidate a further results of timing which show the average of 21.38 seconds. It was found that when the material placement position changed according to the researcher’s designed. The resulted in greater working time of 0.80 second less
