Biomechanics Analysis During Cutting Oil Palm Fronds

The study discusses about lumbar load analysis during cutting oil palm fronds. Initially, oil palm workers were conducting multiple works in the oil palm field. Due to their labour intense work, workers experience musculoskeletal disorders and injuries. Since these disorders occurs during work, they...
