Evaluasi Risiko Ergonomi Stasiun Kerja Filling Di Lube Oil Blending Plant (LOBP) Berdasarkan SNI 9011:2021

Abstract

High-frequency repetitive tasks, non-ergonomic postures, and prolonged working hours in the filling process at
the Lube Oil Blending Plant (LOBP) potentially contribute to musculoskeletal disorders. This study aims to
evaluate ergonomic risks in the box sealing process at the filling workstation using a quantitative approach. The
GOTRAK survey was used as an initial tool to identify musculoskeletal complaints among operators, followed by
assessment using the ergonomic hazard checklist based on SNI 9011:2021. Data were collected through
questionnaires, as well as photo and video documentation of work activities. GOTRAK survey results indicated
the highest complaints occurred in the right and left shoulders, each with a percentage of 68%, caused by repetitive
movements and overhead hand positions. The final risk score was 12, which falls into the hazardous category (?7).
The highest complaints were reported in the right and left shoulder areas due to non-ergonomic postures and
repetitive movements. Control recommendations were provided based on the hierarchy of hazard controls,
including engineering controls through the addition of an adjustable and rotatable lift table, adjustment of table
height, administrative controls such as work and break scheduling, and the use of personal protective equipment
(PPE). These measures aim to reduce ergonomic risks and improve operator comfort.
