Abstract

Research confirms the importance of anthropometry in ergonomic based product design (Wignjosoebroto, 2000). However, a mismatch between facilities and humans as users still occurs. This results in risks to worker safety and disruption in the work process. Pahlawan Tuanku Tambusai University is one of the campuses in Kampar Riau. The campus has a library which is equipped with various facilities, one of which is a trolley. The trolley functions to move books neatly in large quantities. However, employees experience complaints such as back and wrist pain when using this trolley, which can have a negative impact on their health. Therefore, researchers designed a Library Trolley based on the user's anthropometry. This design is equipped with stairs to make it easier to arrange books on high shelves. The size of the Library Trolley is determined based on percentile calculations of body dimensions. The research results show that Standing Shoulder Height (TBB) uses the 50th percentile, namely 133.9 cm. Shoulder Width (LB) using the 90th percentile is 44.547 cm. The 50th percentile for Standing Elbow Height (TSB) is 101 cm. The 10th percentile for Open Palm Width (LTTB) is 16.3 cm, while Fist Height (TKT) uses the 50th percentile, which is 70.32 cm, and Standing Hand Reach Height (TJTB) uses the 10th percentile, namely 207.174 cm.

Abstract

Micro, Small, and Medium Enterprises (MSMEs) along Jalan Kubang Raya encounter substantial challenges in implementing ergonomic principles and managing workplace environmental conditions. Preliminary observations conducted on 20 MSMEs revealed that 85% of workers engaged in non-ergonomic postures 65% consistently worked in a stooped position, while 45% utilized work tables with suboptimal heights (50-60 cm). Moreover, 90% of workers were directly exposed to ambient air pollution and road traffic noise. This community engagement program was developed to enhance ergonomic awareness and improve workplace environmental conditions through four stages of intervention: (1) observation using the Rapid Entire Body Assessment (REBA) method, (2) interactive awareness sessions, (3) hands-on training in simple work tool modifications, and (4) periodic evaluation. The program outcomes demonstrated a significant increase in ergonomic comprehension (from 25% to 82% as measured by pre- and post-tests), a 45% reduction in musculoskeletal pain complaints, and the adoption of safe work practices by 78% of participants. Notably, 65% of the MSMEs independently constructed dust protection devices, contributing to a reduction in pollution exposure by up to 30%. These findings underscore the effectiveness of participatory approaches in promoting occupational health and enhancing productivity in MSMEs operating in high-risk environmental areas. For sustainability, it is recommended to establish local ergonomic cadres and integrate training modules into the programs of the regional Department of Manpower.
