<![CDATA[ABSTRACTThere are still many jobs whose flow is still manually that requires a worker to have more muscle and bone abilities. Sometimes everyone also has limitations, and muscle complaints often occur when doing manual work, especially musculoskeletal disorders (MSDs). Activities carried out at PT Patria Maritim Perkasa are still manual, especially in the blaster section, so many workers complain of aches and pains in their bodies. This study aims to determine the subjective complaints of MSDs, the level of ergonomics risk, and the relationship between work posture, age, body mass index, exercise habits, and smoking habits on MSDs complaints. The tools used are NBM questionnaire, work posture image and employee characteristics questionnaire. The NBM questionnaire showed subjective complaints especially felt at the waist with a score of 23 (90.6%). The method used is the REBA method which produces a high level of risk, namely in the lower sandblasting operation with a score of 9 and during material transfer for sandblasting and preparation of sandblasting equipment with a score of 8. Based on the results of research trials related to MSD complaints are work posture, age and body mass index, exercise habits and smoking habits. There is no relationship with MSD claims, with a significance > 0.05.]]>
