Analisis Postur Kerja Proses Produksi Frozen Food Menggunakan Metode REBA (Studi Kasus Rumah Produksi Enaqween Jember)

Abstract

This study analyzed the risk of musculoskeletal disorders (MSDs) and work posture among workers at the Enaqween Jember Production House using a combination of the Nordic Body Map (NBM) and the Rapid Entire Body Assessment (REBA) method. This research was motivated by high production targets, which often cause workers to engage in static activities, manual lifting, and repetitive movements over long periods, potentially leading to MSDs complaints. Furthermore, research related to MSDs in frozen food MSMEs with rolling work systems is still limited. This study aimed to identify the risk level of MSDs, analyze worker work postures, and provide recommendations for ergonomic improvements. The study used a quantitative descriptive method with a total sampling technique of 16 permanent workers across all production stages: ingredient preparation, grinding, kneading, product shaping, cooking, packaging, and storage. Data were collected through observation, interviews, documentation, and completion of the NBM questionnaire. Work posture analysis was conducted using the REBA method based on measurements of workers' body angles using Angle Meter 360 software. The results showed that workers experienced moderate to high risk MSDs complaints. The dominant complaints were felt in the upper neck, right shoulder, back, waist, right arm, right wrist, and right hand due to repetitive and static work activities. The results of the REBA analysis showed that several work activities were categorized as high to very high risk, such as lifting ground meat (score 8), grinding noodles and skins and moving dough (score 11), forming products (score 10), and packaging activities (score 9). These risks were influenced by bending postures, sitting and standing statically for >2 hours, repetitive hand movements, and lifting manual loads of 5–15 kg. Recommendations for improvement include the implementation of ergonomic work postures, optimization of work facilities, periodic stretching, and visual educational media in the form of ergonomics K3 posters.
