Objective: This study was conducted to assess the risk of sorting tasks for smallscale tomato farmers using an ergonomic assessment tool to provide suggestions for improving their work environment.
Background: In the case of facility-grown crops, productivity improvements and labor savings have been achieved through the introduction of advanced technologies such as automation. However, small-scale farmers have a high prevalence of musculoskeletal disorders. In particular, facility-grown crops such as tomatoes and cucumbers often involve the handling of heavy objects such as harvested crops during sorting. This requires an assessment of the musculoskeletal workload in order to improve the work.
Method: This study conducted a workload assessment of sorting tasks in ten small tomato farms. Field interviews were conducted to analyze the detailed tasks of sorting, and ergonomic assessment tools (RULA, REBA, AWBA) were used to evaluate the risk of working posture. Simulation analysis using 3D SSPP was performed to evaluate the back strain caused by handling heavy objects. In addition, the Borgs RPE scale was used to measure subjective discomfort for each unit task.
Results: The detailed analysis of the sorting task was divided into six unit tasks. According to the ergonomic posture assessment, the harvest unloading and sorting preparation tasks showed a high risk of more than 3 points, and the back strain assessment showed high L4/L5 and L5/S1 compression forces of 2678.6N and 2707.8N, respectively, during harvest unloading. The subjective discomfort of the whole body was measured as somewhat difficult (14 points) or more in all tasks except the harvesting task. The localized discomfort was mainly found in the lower back, shoulders, and arms with the level of difficult (5 points) or more.
Conclusion: As a result of the study, the harvest unloading task showed a high workload among the six unit tasks. In order to improve it, it is necessary to develop a tool or device that can minimize the range of repetitive movements and the angle at which the waist bends and alleviate the burden of the harvesting load. Application: The results of the workload assessment for each unit task can be used to improve the work environment for small tomato farms. The results can also be used to develop ergonomic equipment specific to each unit task.
