Abstract

Product prototype  Ergonomic reflexology vest is an ergonomic intervention recommendation, which serves to reduce or minimize Musculoskeletal disorders such as aches, stiffness, and pain as well as fatigue in the body area of ​​the back, waist, shoulders, and neck of the user. This product features a vertical massaging motor, a vibrator, and its control, a timer, a rechargeable battery, which was designed to be practically foldable and ergonomic because it uses the Indonesian anthropometric dimensions. This product with a number of features was expected to make the body points relax after tired work or activities all day long so that it makes users feel comfortable and able to reactivate. Usability testing of prototype products has been carried out where the result is that prototypes are still lacking and need improvement and development. For this reason, it is necessary to improve and develop the design and features of the vest in order to have better quality. Then the aim of this research is to develop an ergonomic reflexology vest prototype using the method Quality Function Deployment (QFD), through the development of the House of Quality (HoQ), which is the first level of QFD, and to apply ergonomic principles that are effective, safety, healthy, comfortable and efficient. House of Quality (HoQ) aims to translate customer requirements directly to the technical requirements of the products produced. The respondents of this study were drivers car on-line and students were selected based on predetermined characteristic criteria. The results of this study are that there are 15 items Product Attributes as consumer needs and 7 technical requirements. Based on the results of the priority of weights and relative weights, the priority order for 7 items was set: (1) redesigning features, (2) developing and improving design patterns, (3) improving the quality of vest products that are more ergonomic (effective, safety, healthy, comfortable and efficient), (4) quality material selection, (5) testing the ability of vest prototype, (6) warranty service & periodic service, (7) price adjustment with production costs.
