Flower garland makers are at risk of musculoskeletal disorders (WRMSDs) due to repetitive tasks and sitting for long periods in inappropriate postures. This study aimed to assess ergonomic risks and develop the flower garland stringing device in order to reduce ergonomic risks of flower garland makers. Participants in this study consisted of 30 garland makers. Ergonomic risk levels were assessed using the Rapid Upper Limb Assessment (RULA) technique prior to work improvement. The results showed that the riskiest step was threading the flower into the needle with RULA scores of 7 on both left and right sides of the body. The RULA score of 7 is categorized as high risk and needs to investigate and change immediately. Therefore, we developed the flower stringing device and improve the workstation to reduce those ergonomic risks. Usage of the device can reduce working steps that pose ergonomic risks by changing from threading flowers to needle by hands to stringing flowers to needle using the device. The device can reduce repetitive pinch grip and workstation improvement leading to the proper sitting posture. After work improvement, the satisfaction score was higher
than that of before improvement on the appropriateness of shapes and materials used in work, the convenience of working, workstation and working environment. However, the device for threading flower garlands should be improved to be able to thread flowers more quickly and make the garland to be more beautiful with higher quality.
