Appropriate and Efficient Technology System Approach in Product Design to Reduce Musculoskeletal Disorders

The process of planting corn still uses the traditional method of using wood that is sharpened at the end while holding a bag containing corn seeds, the process of planting corn is carried out by bending the body continuously, this process is carried out minimum two workers. This process causes performance to be not optimal, besides that the work process will accelerate fatigue and cause many complaints, pain, and injuries. This study aims to measure anthropometric data of standing shoulder height, standing elbow height, forearm length, hand width, and hand grip diameter. The results of these measurements are then used to design products for these farmers. This measurement also includes a Nordic Body Map (NBM) questionnaire to determine of pain in the corn planting process. The subjects in this study were 30 people, after calculation and data processing, the right size for the product design is obtained which consists of a tool height of 140 cm, a handle height of 105 cm, a diameter of grip 5 cm, grip length of 9 cm, an operator distance with a tool of 45 cm, then the tool assembly process and testing process will be carried out.
