Analisis Penilaian Postur Kerja Berdasarkan SNI 9011:2021 Pada Pekerjaan Pengelasan Pipa Di Perusahaan Galangan Kapal

Abstract

Continuous production is one of the company's achievements. However, in pursuing this goal, the company has not paid sufficient attention to ergonomic aspects. The fabrication activity involves pipe welding used for connecting and repairing ship pipes. During the pipe welding process, workers often adopt awkward postures, such as squatting, bending the torso, bowing the neck, and flexing the wrists for extended periods, which may lead to Musculoskeletal Disorders (MSDs). The main objective of this study is to measure and analyze working postures and provide recommendations for improvement. This research is based on the SNI 9011:2021 standard using a quantitative method tailored to actual conditions. The GOTRAK questionnaire results indicate that 13% of all workers are at a moderate risk level, while 7% are at a high-risk level. Body parts identified with high-risk levels include the shoulders (20%), arms, and knees (13%). After conducting the assessment, a total score of 14 was obtained, indicating a hazardous condition that requires workstation improvement recommendations. These improvements were simulated using CATIA software, involving the addition of work facilities such as pipe supports and adjustable chairs tailored to the anthropometric data of Indonesian males to reduce potential ergonomic hazards faced by the workers.
