Penilaian Desain Produk dengan Assembly Analysis And Line Balancing Spreadsheet dan Ullman 13 Guidelines untuk Meningkatkan Kinerja Perakitan

摘要

In an industry that produces product with a quite many components, assembly process usually is the most cost-determining process. Realizing that almost all products are assembled from some components and that the assembly process itself takes time, then products as much as possible are made to be assembled easily.Product design that is not proper will cause a very high numbers of components that, in turn, will reduce the reliability of that product. Finally, it will increase the assembly cost. That\u27s why product design needs to be evaluated for assembly purpose.The purpose of this research is to evaluate product design by Assembly Analysis and Line Balancing Spreadsheet (AA&LBS) method. Then, the old design is improved to get a new design. The new design is compared the one resulted from Boothroyd Dewhurst (BD) method, where assembly time reduction, efficiency improvement, assembly cost reduction, and Ullman\u27s 13 Guidelines method are used as the criteria.Of the data analysis, assembly time reduction of AA&LBS method is almost 2.7 times, and assembly cost reduction is almost 2.5 times than of BD method. AA&LBS method also resulted in average efficiency improvement that is larger, i.e. 11.08%, while BD method is only 0.08%. According to Ullman\u27s 13 Guidelines method, AA&LBS method has a total score of 1062, while BD method has a score of 1060.
