Laundry workers and room attendant activities have Musculoskeletal Disorders risk in association with awkward posture in long duration, repetitive movements, and routine activity. The study was conducted to assess the working risk by using Rapid Entire Body Assessment (REBA) and Musculoskeletal Disorders symptoms by using Nordic Body Map. The REBA result shows there are 13 laundry worker?s activities with medium risk, 2 activities with high risk, and 1 activity with very high risk. For room attendant group, there are 2 activities with medium risk, 3 activities with high risk, and 1 activity with very high risk.

The Nordic Body Map questionnaire result shows the most perceived Musculoskeletal Disorders symptom by the laundry workers are the symptoms that felt on right and left shoulder. For the room attendant group the most perceived Musculoskeletal Disorders symptoms are the symptoms that felt on waist, right and left calf. The most felt Musculoskeletal Disorders symptoms that felt by the workers are aches, pain, and cramps. Besides of the working posture, the worker?s individual characteristics aggravate the MSDs symptoms like age, sex, physical activity, and Body Mass Index (BMI). Most of activities have their own MSDs symptoms level of risk that required corrective action for the design of the workplace.
