Abstract
The cassava (Manihot Utilissima) can be processed into many kinds of processed cassava, one of them is the cassava Opak chips. The cassava Opak chips is a traditional snacks similar with the most popular crackers, made of a tasty, round and thin, boiled cassava. The cassava chips, for all this time, become the source of living for the community of processed cassava include another processed cassava. This business classified as home industry because it’s production processed individually in each producer’s home. In the home industries or small industries, the cassava Opak chips production processed manually with the quality product which hasn’t meet the standard of food quality and customer needs. Therefore, need to do the cassava Opak chips quality improvement so they can produce the snacks. The cassava Opak chips made of cassava which can give the attraction and the quality warranty to the consumer. This observation aims to designing the cassava Opak chips product which has the certain quality based on consumer needs and wishes with the Integrated Quality Function Deployment (QFD) Method and Fuzzy Theory. This observation performed by interviewing the consumer, the Voice of Customer forming, questionnaires distribution, GAP calculations, technical characteristics determination, the House of Quality matrix making, draft concepts development, part specification determination, Part Deployment matrix making, and visualization design. Based on the result of the processed data on first and second iteration on QFD, we can get the technical classification and specification part, also recommendation to improve the cassava Opak chips product’s quality.
Keywords: Cassava Opak chips, QFD, voice of Customer, fuzzy theory
