Background: The sports facilities for the tonnis game in the form of a net and two poles symmetrically mounted on the right and left in accordance with the dimensions of the field are not ergonomically designed. The Dimensional design of the pole is very varied and using materials that are not standardized. The sports facilities of tonnis game are only designed for its function, but it has not considered the ease, speed, and convenience during assembling and disassembling by workers. It was found that the net pole ballast system exceeds the capabilities, limitations, and human capacity. Workers who perform assembling and disassembling activities of tonnis facilities are found unnatural movements in their body. It reduces the quality of their health. Thus, it is needed to redesign tonnis sports facilities with ease and needs of users in order to improve the health of workers through the reduction of fatigue, musculoskeletal disorders which result in an increase in convenience of work. Object: The subjects in this study are the workers who assemble and disassemble net and the poles in tonnis sport. It starts from taking the sports facilities of the barn into the field, assembling the net and the poles on the right side and the left symmetrically. Criteria of the place used as a point of sampling is a closed field designed specifically for sporting activities with different types of games. Methods: This study is an experimental research by using subject design. Subjects were selected by using random sampling. Samples of 144 people had met the inclusion and exclusion criteria. Results: The results showed that there is significantly increase with an average score of general fatigue amounted to 24.65%, consisting of activity fatigue by 26.60%, exhaustion by 23% motivation, and physical exhaustion by 24.31% (p <0.01), whereas the decrease in musculoskeletal disorders amounted to 23.98% (p <0.01). So overall, with an increase in work health, with the increase of worker comfort in assembling net and the poles the tonnis game amounted to 21.69% (p <0.01). Conclusions: Redesigning Participatory-Ergonomics-Based Sports Facilities is able to improve the quality of healthcare that can be seen from the reduction in fatigue, musculoskeletal disorders and the increase of convenience of work. Participatory ergonomics approach not only can redesign facilities, but also can increase the workerâ€™s roles in the improvement of the physical health of workers.
