Abstract

The results of preliminary observations of the working conditions and environment of freight workers in the 16 Ilir Market, Palembang City, South Sumaetera Province are categorized as less ergonomic in physical, work environment, psychological, organizational and management aspects. Freight workers work by placing baskets on their heads, on their backs and even some without tools directly on their shoulders which load basic food items, and loading-unloading warehousing goods, weighing ±35 kg, a distance of ±500 meters with a low level of productivity. After finishing work, freight workers experience aches all throughout the body, particularly in the legs and neck, as well as waist and back pain. Based on work pulse frequency, the workload was determined to be 131.25±14.10 beats per minute, and it was categorized as heavy work. The fatigue score reached 69.10±15.29 and the musculoskeletal disorder score was 61.25±7.44. The method used is a total ergonomics approach, to enhance work productivity by reducing workload, fatigue, and musculoskeletal system issues. Thirty research samples were chosen by simple randomization of freight workers for this same-subject experimental study. The Wilcoxon Signed Rank Test and the t-paired test were used to evaluate the data at a 5% significance level. Workload, weariness, and musculoskeletal complaints significantly decreased, and productivity increased (p<0.05), according to the data. In conclusion, the total ergonomics approach reduced workload as seen from the decrease in: work pulse rate by 15.61%, fatigue by 58.97%, musculoskeletal system complaints by 28.78%. Consequently, there was a 21.00% increase in productivity. The total ergonomics approach can improve the quality of life and work productivity of freight workers in 16 Ilir Market, Palembang City, South Sumatera Province

Abstract

Background: Computers are the main devices that support the efficiency and effectiveness of work in modern office environments, including MSMEs in South Sumatra Province. However, long-term use of computers with unergonomic sitting postures can increase the risk of Work-Related Musculoskeletal Disorders (WMSDs) in workers. The results of preliminary observations showed that the percentage of variation in WMSD complaints was between 13%-42% of the total work-related diseases related to computers. Aim: This study aims to identify muscle complaints experienced by workers, analyze the risk of working posture using ergonomic methods, and provide suggestions for improvements to minimize the risk of musculoskeletal disorders. Methods: This study uses the Rapid Office Strain Assessment (ROSA) method to assess the risk of computerized and sitting activity-based work postures. In addition, Nordic Body Map was used to map the location of muscle complaints in respondents. The study was conducted on 20 workers in four MSMEs in South Sumatra Province who worked with high computer intensity. Results: The analysis showed that all four respondents had a high level of occupational posture risk based on the ROSA score. A total of 36 muscle complaints were reported, with the most complaints located in the lower neck, waist, and buttocks. The main factors causing complaints include prolonged static sitting positions and inadequate adjustment of work facilities. Conclusions: The work posture of MSME workers in South Sumatra Province indicates a level of ergonomic risks that requires serious attention. Interventions such as improving work facilities and training in correct work posture are highly recommended. Implementation. These findings affirm the importance of applying ergonomic principles in computer-based work environments to prevent WMSDs, improve work comfort, and support the productivity of government sector workers.
