      Abstract
      Penebangan pohon jati di Indonesia menggunakan chainsaw masih didominasi dengan sistem munual material handling. Kegiatan dengan sistem ini memiliki tingkat risiko musculoskeletal disorders (MSDs) yang tinggi akibat disertai beban chainsaw yang berat dan postur tubuh janggal/ekstrem pada operator. Diperlukan tindakan untuk mengurangi risiko MSDs dalam kegiatan penebangan jati dengan analisis postur kerja ekstrem yang efektif dan aksi ergonomi. Penilaian risiko MSDs dilakukan menggunakan instrumen Rapid Entire Body Assessment (REBA) dan Rapid Upper Limb Assessment (RULA). Hasil analisis postur kerja menggunakan metode REBA memiliki tingkat risiko MSDs yang bervariasi daripada RULA yang secara keseluruhan kegiatan penebangan jati berisiko ergonomi sangat tinggi. Sehingga penilaian postur kerja pada kegiatan penebangan pohon jati, instrumen RULA lebih disarankan karena sensitivitas yang dimiliki lebih tinggi daripada REBA. Adapun aksi ergonomi untuk mengurangi risiko pada postur kerja operator chainsaw berupa perbaikan postur dengan menghindari postur membungkuk dan mengganti dengan postur berlutut, menggunakan alat chainsaw dengan beban yang lebih ringan dan pemeliharaan alat yang baik, serta adanya penambahan durasi istirahat operator untuk relaksasi otot tubuh.
       
      The felling of teak trees in Indonesia using chainsaws is still dominated by the munual material handling system. Activities with this system have a high level of risk of musculoskeletal disorders (MSDs) due to heavy chainsaw loads and awkward/extreme postures for operators. Action is needed to reduce the risk of MSDs in teak felling activities by analysing effective extreme work postures and ergonomic actions. MSDs risk assessment is carried out using Rapid Entire Body Assessment (REBA) and Rapid Upper Limb Assessment (RULA) instruments. The results of work posture analysis using the REBA method have varying levels of MSDs risk than RULA, which overall teak logging activities are very high ergonomic risk. So that the assessment of work postures in teak logging activities, the RULA instrument is more recommended because of its higher sensitivity than REBA. As for ergonomic actions to reduce the risk in the work posture of chainsaw operators in the form of posture improvement by avoiding slouching postures and replacing them with kneeling postures, using chainsaw tools with lighter loads and good tool maintenance, and increasing the duration of operator breaks for relaxation of body muscles.
