Penilaian Postur Kerja dan Risiko Musculoskeletal Disorders Menggunakan Analisis Biomekanik Pada Kegiatan Penyadapan Kopal di Hutan Pendidikan Gunung Walat

Abstract

Penyadapan kopal adalah salah satu kegiatan pemanfaatan hasil hutan bukan kayu (HHBK). Kegiatan penyadapan kopal memiliki risiko yang membahayakan kesehatan dan keselamatan pekerjanya seperti Musculoskeletal Disorders (MSDs). Tujuan penelitian ini adalah mengidentifikasi level risiko postur kerja menggunakan Range of Motion (ROM), menghitung gaya tekan lumbal 5 dan sakrum 1 (L5/S1) menggunakan analisis biomekanik, dan memberikan rekomendasi perbaikan postur kerja yang sesuai. Postur tubuh pekerja dianalisis dengan ROM yang kemudian dilanjutkan dengan analisis biomekanik menggunakan software 3DSSPP (3D Static Strength Prediction Program) serta beberapa analisis objektif lainnya seperti OWAS (Ovaki Working Posture Analysis System) dan QEC (Quick Exposure Check). Analisis biomekanik menyajikan hasil berupa compression force, shear force, strength percent capable, dan standing balance. Metode analisis data dilakukan pada setia postur kerja yang dihasilkan dalam kegiatan. Hasil analisis menunjukkan bahwa segmen tubuh yang sangat berpengaruh terhadap risiko MSDs yang diterima oleh pekerja yaitu leher, punggung, pergelangan tangan, pinggul, dan lutut.

Copal tapping is one of the non-timber forest product (NTFP) utilization activities. Copal tapping activities have risks that endanger the health and safety of their workers, such as Musculoskeletal Disorders (MSDs). The purpose of this study was to identify the level of risk of working posture using Range of Motion (ROM), calculate the compressive force of the 5th lumbar and sacrum 1 (L5/S1) using biomechanical analysis, and provide recommendations for improving the appropriate working posture. Workers' body postures were analyzed by ROM which was then followed by biomechanical analysis using 3DSSPP software (3D Static Strength Prediction Program) as well as several other objective analyzes such as OWAS (Ovaki Working Posture Analysis System) and QEC (Quick Exposure Check). Biomechanical analysis presents the results in the form of compression force, shear force, strength percent capable, and standing balance. The data analysis method is carried out on each work posture generated in the activity. The results of the analysis show that the body segments that greatly influence the risk of MSDs received by workers are the neck, back, wrists, hips, and knees.
