DESIGN OPTIMIZATION OF A VERTICAL TYPE PAPAYA GRATER USING QFD METHODS

Abstract

Market demand for papaya processed products such as papaya dodol, jam, and sweets is increasing, so tools are needed that can speed up the processing process, especially grating papaya. This study aims to optimize the design of papaya grater machine by using QFD method approach. This method is used to produce a systematic and efficient design through structured stages, starting from needs analysis, function formulation, solution development, to final design. In the process, various alternative concepts were evaluated based on the criteria of performance, ergonomics, ease of maintenance, and production costs. The optimization results show that the final design of the machine has a capacity of 10 kg/hour with an increased work efficiency of up to 45% compared to the manual method. The machine was also designed with ease of operation and user safety in mind. With the QFD approach, the design process becomes more focused and produces products that are more optimal for the needs of the home industry and MSME scale.
