Harvesting, loading and sorting activities in palm oil industry that conducted manually have some risks that can cause musculoskeletal disorders (MSDs). This is happened due to repetitive of manual working, standing and bending position for 10 hours and 6 working days, this activity does not match the anthropometry of worker body. Questionnaire analysis Nordic body MAP showed that the biggest complaints from workers are on their backs (90%), waist (89.3%), left calf (90%) and right calf (89.3%). Ergonomic risk analysis by OWAS Method also support the questioannaire analysis with result that the shoulders stooping attitude done by 68% workers (category 2), both arms above the shoulder attitude done by 53% (category 2), and leg rest to the two knee which is bent done 47% (category 3) with harvesting ergonomic combination 4-2-2-2 (category 3). Ergonomic analysis result in harvesting activity is CVL 51% (7.25 Kkal/minutes), Loading activity 55% (8.58 Kkal/minutes) and sorting activity 40% (6.6 Kkal/minutes) with medium category. Therefore, improvement is required because workers has fatigue. Correlation analysis using spearman rank test showed that the influence of ergonomics in harvesting and sorting division has a significant relation with value 0.00027 (OR 10 CI 95% 1.56-64.2) in harvesting and 0.0008 (OR 11 CI 1.7-71.28) in sorting. There was significant relation (p<0.05) between ergonomics and muscolekeletal disorders. <br /> <br />
