Abstract

PT XYZ is engaged in the stamping and welding that produces various kinds of high-quality parts. There is a mismatch between the amount of material released with production, while the material tracking system applied does not provide clear information about the flow of material issued for production processes. This led to the use of the material becomes less effective. Material tracking system used is form called identity tag. This study aims to: (1) determine the influencing factors of problems on the amount of material work in process both planned and actual, (2) determine what types of most frequent problematic products on the amount of material work process, (3) determine an appropriate and effective system for PT XYZ in implementing manufacturing processes, (4) optimize the use of raw materials produced. Methods to solve the above problem are plan, do, check, action (PDCA) assisted with tools such as histograms, Pareto charts, cause-effect diagrams and kuesione. The result obtained and taken into consideration is giving improvement suggestions, which are doing more inspections by the production leader to reduce the error information written on the identity tag, and providing some additional columns, such as description and causes of the reduce in the amount of material that most often occurs. Based on the implementation results, the discrepancy percentage in the identity tag proposals decreases to 45.45% for small part, 53.33%, for medium part and 12.5% for large part, with a total percentage of 37.74% in week 1.

Abstract

PT “XYZ”is a manufacturing company specializing in pressed metal parts, dies, jigs and fixtures which is equipped with high-tech equipment and qualified human resources. PT “XYZ”used a system of safety stock (buffer stock) of three kanban to anticipate a shortage of stock or production of raw materials in the production process. A research was done at PT “XYZ”which focused on the degree of conformity between actual production planning by the state was obtained on the basis of the measurement of the product cycle, production capacity, actual production, production planning and material needs. The plan scheduling and material requirement planning used lot for lot method. It is needed to set the production scheduling with consideration of actual production plan where the production capacity of each product to be examined, namely the process ofbending klem = 680 pcs/hour, brake with bending process II = 680 pcs/hour and plat with a capacity of blank process = 1.888 pcs/hour which are used the maximum production capacity. Lead time and safety stock are also considered as factors affecting the scheduling. From the result of making MRP, we found that the material ordering must consider the capacity of a coil for each item and the on hand (inventory) from the last production. The production planning proposal of this research was able to fulfil the supply as many as three kanban. In addition, the planning could increase the work productivity as well as time and cost efficiency. The MRP with lotfor lot method was declared valid because it fulfilled the assumptions of MRP for some products. PT “XYZ”is expected to plan a system of procurement of raw materials and production systems in order to meet market demand with the number of raw material orde. The company was expected to pay attention to lead time to reduce the risk of material shortages for production.
