Usulan Perbaikan Rancangan Kipas Portable dengan Menggunakan Metode Design For Manufacture and Assembly (DFMA) dan Model Kano

Abstract

Electronic devices are operated devices that use electrical energy as an energy source and transform this energy into other energy. The use of electronic devices, which have now become the main tool for society, will be hampered if the electronic devices are damaged. One electronic device that often experiences damage is a portable fan. Problems that occur in portable fan products through observations at PT Industrial Multi Fan include damage and problems in the portable fan assembly process. Problems with product damage include burnt out dynamos, damaged components, and slow rotating fans. Problems in the assembly process include a large number of components, design and use of components that make the assembly process difficult and less efficient. The aim of this research is to improve the design of portable fans to suit consumer needs and increase product assembly efficiency. Improving the portable fan design begins with identifying customer needs using the Kano Model, there are 3 attributes in the attractive category, 1 attribute in the must bee category, and 6 attributes in the indifferent category. The focus of repairing portable fans is based on 3 attractive attributes, namely the use of nuts, depth of component insertion, and number of components. Improvements to the kipas portable design were carried out using the Design for Manufacture and Assembly (DFMA) method which takes into account the ease of the manufacturing and assembly process. Improvements in the design of the portable fan resulted in improvements to the design of the body cover and bottom cover which replaced the function of nut A with a snap fit locking system and reduced the installation depth of nut B to 0.5 cm. The results of these improvements resulted in a reduction in assembly time from 264.33 seconds to 231.18 seconds, increased design efficiency from 24.97% to 25.95%, and reduced assembly costs from IDR 712.30/unit to IDR 623.05/unit
