Balinese aromatherapy product development based on Kansei Engineering and customer personality type

Balinese aromatherapy products have such local indigenous that attracts customer attention. The combination of aromatherapy product and Balinese culture make this product become unique and famous in the market. In this re-search affective engineering approach based on Kansei Engineering was applied to develop Balinese aromatherapy product. Customer personality type based on Hippocrates and Galen theory was involved in the development process. According to its main motivation, three research objectives were proposed (1) to generate the new design concept of Balinese aromatherapy product using Principal Component Analysis (PCA), (2) to identify the relevant product design element using Relief method, and (3) to generate the quantification model of aromatherapy product design using Fuzzy Quantification Theory Type 1 (FQTT1). The result of PCA method showed the extraction of KW collected has been reduced twelve components into one principal component to represent new design concept named "Balinese Traditional" (BT). By using Relief method, ten relevant design elements have been generated from twelve design elements identified. According to the result of FQTT1 analysis, a linear quantitative model has been built for each personality type to explore the relationship between customer's emotional feelings and product design elements. From these models, design support information has been generated to assist product designers in decision making for the new Balinese product design. In general, the result showed that all design specification of Balinese aromatherapy product were specific for each personality and most of them were productive as the new design rules.
