Judul: Risk Assessment Musculoskeletal Disorders and Workload Recommendations with Biomechanical Approach of Copal Collection in Gunung Walat Educational Forest
Abstrak: Pengumpulan kopal merupakan salah satu kegiatan pemanfaatan hasil hutan bukan kayu (HHBK) yang berisiko menimbulkan gangguan keselamatan dan kesehatan kerja (K3). Kegiatan pengumpulan kopal mencakup berbagai kegiatan manual material handling (MMH) yang dapat menimbulkan musculoskeletal disorders (MSDs). Keluhan rasa sakit pada bagian tubuh pekerja dari yang paling terdampak, yaitu punggung, pergelangan tangan kanan, pinggul, bahu kanan, bahu kiri, dan pergelangan tangan kiri. Postur tubuh pekerja dianalisis dengan Range of Motion (ROM), kemudian dilanjutkan dengan analisis biomekanik menggunakan software 3 Dimension Static Strength Prediction Progam (3DSSPP). Analisis biomekanik menyajikan hasil compression force dan shear force pada lumbar ke-5 sacrum ke-1 (L5/S1), strength percent capable, dan standing balance. Postur kerja yang memiliki compression force >3400 N yaitu postur jongkok dan berdiri membungkuk pada elemen kerja mengangkat getah. Hasil Recommended Weight Limit (RWL) diperoleh sebesar 7,72 kg dan Lifting Index (LI) sebesar 2,59, yang artinya termasuk pekerjaan berisiko sedang., Copal colleting is one of the non-timber forest product (NTFP) utilization activities that has the risk of causing occupational safety and health (OSH) disturbances. Collecting copal include various manual material handling (MMH) activities that can cause musculoskeletal disorders (MSDs). Pain complaints against the body parts of the worker from the most affected such as the back, right wrist, hip, right shoulder, left shoulder, and left wrist. The body posture is analyzed with Range of Motion (ROM), then followed by biomechanical analysis with 3 Dimension Static Strength Prediction Progam (3DSSPP) software. The biomechanical analysis presents the results in compression force and shear force at 5th lumbar, 1st sacrum (L5/S1), strength percent capable, and standing balance. The working posture that has the highest compression force >3400 N is the squatting dan standing bent posture on the work element lifting latex. The Recommended Weight Limit (RWL) obtained 7.72 kg and the Lifting Index (LI) is 2.59, which means it is classified as a medium-risk job.

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