Perancangan dan Perbaikan Microwave Oven dengan Pendekatan Quality Function Deployment (QFD) dan Axiomatic Design (AD)

Abstract

Electronic devices cannot be separated in everyday life so that in their use they often experience damage. One of the electronic devices often damaged is a microwave oven. A microwave oven is a rectangular metal box with a hole or several holes through which microwave energy is channeled into the oven cavity. The problem often occurs is the lack of temperature in the oven cavity, so it is necessary to design microwave oven product improvements using the Quality Function Deployment Phase I and II methods to obtain technical characteristics and critical parts of the product based on consumer voices and Axiomatic Design to obtain design parameters according to the functional needs of the product. The results of Quality Function Deployment Phase I obtained priority technical characteristics namely cooking performance and food quality while in Quality Function Deployment Phase II obtained priority critical parts namely user interface, internal sensors, and door lock system which were converted into functional requirements as input to Axiomatic Design. In Axiomatic Design, it is found that there are 3 design parameters included in the uncoupled design category and 6 design parameters included in the decoupled design category. Uncoupled design and uncoupled design are design categories that fulfill the first axiom of Axiomatic Design, namely the independence axiom. The new design has decreased in terms of information content by 0.4995 bits compared to the actual design, so the new design has improved compared to the actual design
