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

High variation in the types of toy produced in a multinational toy manufacturing company results in excessive variation in the types of soft good fabricated. A real-time and precise information flow from the release of the bill of materials (BOM) to the execution in the production floor is crucial in ensuring the smooth soft good mass production flow. On time production process of nondurable goods or so-called soft goods requires real time information of the progress update during the production of dolls costumes. The research is conducted to determine the most effective information system tool in catching delay and its cause of lateness in costume development process. The tool allows control of production system primarily in the input and process area and utilizes the earliest due date (EDD) sequencing method to minimize the maximum delay in the information transfer. Upon implementation, accurate and according-to-the-needs information is retrieved in real time which increases the efficiency of production process of the soft goods significantly.

Abstract

The main objective of the study is to implement a variety of tools necessary for the design of an effectiveness warehouse for company X. The first two phases (warehouse activity profiling and warehouse design) are finished. The proposed warehouse design for company X has two floors, which are ground floor and mezzanine. Bin-shelving area, pallet and floor storage area, shipping area, and receiving area are put in the ground floor. The pallet and floor storage area is further divided into four zones: Pallet rack, Floor storage zone, Special pallet zone, and Heavy pallet zone. The shipping area of 4,784 square feet will have five shipping doors which includes the staging area in front of the docks. The receiving area requires approximately 4,000 ft2. Class C SKUs according to viscosity will be put in the mezzanine area which utilizes the vertical space of the building. This area is accessible from forklifts using a spiral corridor close to the receiving area. The warehouse processes will include batch order picking in improving labor hour utilization and high viscosity SKUS shall be placed in the most convenient location of the warehouse.

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.

Abstract

PT. XYZ is a company engaged in manufacturing porcelain dinner ware such as plates, cups, teapot, bowl, etc Porcelain product is safe for use and product defect will only affect the aesthetic not the functional side. The company always maintain the quality of the products produced as by maintaining a good product, in terms of visuals, will keep customers interested in the product. Good quality products characterized by quality A / B and C, and the product defect characterized by the quality of D, Lost, and BU. Concepts and methods used to analyze is a statistical process control (SPC) which includes Pareto diagram, fraction nonconformities, flow charts and fishbone diagrams and management tools (fault tree analysis). Statistical Process Control (SPC) is one of the methods, which includes Pareto charts, fraction nonconformities, flow chart, and fishbone diagram and also management tools (fault tree analysis). SPC is useful to find the facts from the problems and factors that affect the quality of the products, while fault tree analysis is useful to analyze each of the production process.

Abstract

Product Quality Division is in charge to do testing and verification of motorcycle prior the order for mass production items needed. The testing is prepared by the testing department which sends the list of items needed to the warehouse to be ordered. 20 - 43% of the items needed for testing are delayed which drives thetesting department to directly order the same parts to ensure the testing is conducted on time. Crucial parts are determined through Pareto analysis and Newsboy Problem inventory model is used as the inventory system. Based on the simulation of new model project using the proposed inventory system, up to 88% of the total cost of part loss in each project can be saved.
