Perbaikan Rancangan Produk Blender Menggunakan Model Kano dan Design For Manufacture and Assembly (DFMA)

Abstract

Electronic devices are devices that use electricity as energy and transform this energy into other energy. The use of electronic devices will be constrained if there is damage to the electronic device. One of the electronic devices that is often damaged is a blender. Problems that occur in blender products through observations on UKM Pinem Service Electronics are in the form of damage and problems with the blender assembly process. Product damage problems include burnt dynamos, damaged components, slow rotation, and blades not rotating. While the problems in the assembly process include the large number of components, complicated designs and the use of nuts that make it difficult and less efficient in the assembly process. The purpose of this research is to improve the design of blender products according to customer needs and increase the efficiency of blender assembly. Improvement of the blender design begins with identifying customer needs using the Kano Model. Based on the results of the Kano Model, there are 3 attributes in the Attractive category, 1 attribute in the must be category, and 6 attributes in the indifferent category. The focus of blender improvement is based on 3 attractive attributes, namely the use of nuts, the depth of component insertion, and the number of components. Improvements to the blender design were carried out using the Design for Manufacture and Assembly (DFMA) method which considered the ease of manufacturing and assembly processes. Improvements to the blender design 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 depth of installation 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.
