Investigation of oil palm harvesting tools design and technique on work-related musculoskeletal disorders of the upper body

The oil palm industry is one of the important sectors in Malaysia. growth and development this shows that Malaysia world second-largest producers. However, fresh fruit bunch (FFB) harvesting process, harvesters are exposed to many types work-related musculoskeletal disorders (WMSDs). FFB tend develop WMSDs especially shoulders trunk. Hence, it identify exposure levels, awkward postures reaction forces muscle activity based on posture movement when using pole, chisel loading spike during process. objective study was investigate effect design tools upper body. Rapid Upper Limb Analysis (RULA) used assess level harvester body assessment showed trunk have high undergo posture. Human Musculoskeletal Model (HMMA) force exerted In study, 4 muscles were analysed including Triceps, Biceps, Erector Spinae Psoas Major. highest 16.36 N found left triceps handling a spike. conclusion, address risks by reviewing all possible aspects contribute interventions tool design, task working shifts may be required. • Work-related three different towards movement. eight human model analysis. Comparison between rapid limb analysis (HMMA).
