Solving Office Ergonomics Problem Using Rapid Upper Limb Assessment (RULA)

This research took place in the Industrial computation laboratory, where the main function of the laboratory as a place of practical activity related to industrial engineering software for students. From the results of the Nordic Body Map preliminary questionnaire (NBM) showed that the highest percentage after students doing computer practically for 2 hours was the pain in the sitting position when operating the computer (typing and holding the mouse). Based on the analysis that has been used with the RULA method for positions at the time of computer operation, the results of risk level 3 to 4 are obtained (long-term action is needed) and the risk level is 5 6 (immediate action is required). To reduce the level of student injury risk during the learning process, this research proposes a redesign work desk position and seat position with a work station design approach based on student’s anthropometric data by utilizing RULA. The three results of work station design proposals, computer desks namely table mat height 78 cm, 83 cm wide, and 45 cm long, 68 cm height keyboard and for chairs namely 49 cm seat height, 42 cm seat base width, 46 cm pedestal length, width of backrest 42 cm, height of backrest 58 cm with a slope of 5 degree. By paying concern to the student’s posture, the design proposal should appropriate and decrease the risk level of students who operating computer into level 1 – 2 (acceptance posture)
