Penelitian ini bertujuan menganalisis hubungan antara postur kerja, beban kerja fisik, dan kelelahan kerja pada pekerja industri padat karya. Penelitian menggunakan pendekatan kuantitatif deskriptif dengan desain observasional cross-sectional terhadap 30 pekerja di enam stasiun kerja PD Jangkar. Postur kerja dinilai menggunakan Cornell Musculoskeletal Discomfort Questionnaire (CMDQ), beban kerja fisik diukur melalui Cardiovascular Load (CVL), dan kelelahan kerja dievaluasi menggunakan Subjective Self Rating Test (SSRT). Hasil menunjukkan keluhan muskuloskeletal tertinggi terjadi pada bahu (80%), punggung bawah (73,3%), dan pinggang (66,7%). Sebanyak 43,3% pekerja memiliki nilai CVL di atas 30% yang menunjukkan beban kerja berat. Analisis korelasi menunjukkan hubungan kuat antara postur kerja dan kelelahan (r = 0,68; p < 0,05) serta hubungan sangat kuat antara beban kerja fisik dan kelelahan (r = 0,81; p < 0,01). Penelitian ini menegaskan pentingnya pendekatan ergonomi integratif untuk menurunkan kelelahan dan meningkatkan produktivitas pekerja
