Work motion study on coconut tree climbing using a portable coconut climbing equipment

Abstract

Coconut tree climbing activities in general in the Aceh region are still carried out traditionally, namely climbing directly by coconut farmers which still rely on human labor which is classified as difficult and has a high risk in terms of work safety and musculoskeletal disorders (MSD). The aims of this study were (1) analysis of posture and work movements in climbing coconut trees with a portable coconut climber, (2) a comparison of the level of comfort with a portable coconut climber and a traditional coconut climber. Tests are carried out subjectively and objectively, subjective tests are carried out based on perceived operator subjectivity complaints with the Nordic Body Map (NBM) while objective testing is based on the Range approach. of Motion (ROM) and using the Rapid Entire Body Assessment (REBA). The results of the range of motion analysis (ROM) show that traditional climbing has a higher risk of motion for the operator compared to climbing using a portable coconut climbing equipment. REBA work posture analysis shows that traditional climbing has an average score of 10-11 (very high risk), while using the REBA tool the average score is 4-5 (moderate risk). In the analysis of the Nordic Body Map (NBM), traditional climbing received 42 complaints while climbing equipment experienced 18 complaints of discomfort. Some ergonomic interventions are needed to increase safety and comfort in climbing coconut trees.
