Abstract

Technical drawing tables play a crucial role in facilitating the creation of intricate component and structural designs. However, the modification of original drawing table at Politeknik Manufaktur Bandung has raised significant concerns regarding the ergonomic challenges, underscoring the importance of evaluating potential risks to users’ posture and musculoskeletal health. Addressing the issue, this study utilized the Nordic Body Map (NBM) and Rapid Upper Limb Assessment (RULA) methods to identify students’ musculoskeletal complaints and evaluate posture-related risks associated with the modified tables as well as recommending optimal table dimensions. A total of 42 students participated in the study, with results indicating that 31 students (73.8%) exhibited a low risk of injury, 9 students (21.4%) faced a moderate risk, and 2 students (4.8%) were at a high risk. The most commonly reported musculoskeletal discomforts included pain in the upper neck, lower neck, shoulders (right and left), back, waist, hips, and right hand. RULA assessments revealed scores ranging from 6 to 7 among participants, reflecting moderate to high-risk levels that require immediate ergonomic intervention. To mitigate these risks, an evaluation of the modified table dimensions was conducted using anthropometric data from the respondents. The study proposed the following dimensions for the drawing tables; a width of 65 cm, a height of 78 cm, a length of 88 cm, and a footrest width of 14.5 cm.
