The Effect of Age and Workload on Work Posture toward Musculoskeletal Disorders Complain on Loading and Unloading Workers

Background: Workers in informal sector such as loading and unloading workers have a risk of experiencing health disorder of occupational disease such as musculoskeletloadingal disorders (MSDs). Such complain usually occurs on spine (back and neck) and upper limb. Most of the loading and unloading workers work using manual material handling, such as loading, unloading, pushing, pulling, throwing, moving, or rotating loads using their hands or other body parts. Such work method has musculoskeletal disorders (MSDs) risk, including low back pain. There are several factors causing the musculoskeletal disorders (MSDs) including individual factors (age and gender), work factors (workload and work posture), and work environment factors. Objective: The purpose of this study was to determine the direct and indirect effects of age and workload with work posture as an intervening variable against musculoskeletal disorders (MSDs) on loading and unloading workers at PT. Pelabuhan Indonesia IV (Persero) of Makassar Branch. Methods: The current research applied analytical observation with a Cross-Sectional approach involving 140 respondents selected through a simple random sampling technique. This research was further carried out at Pelabuhan Indonesia IV (Persero) of Makassar Branch in April-May 2021. Data obtained were analyzed using univariate, bivariate, and multivariate analysis. Results: There were 65 respondents (46.4%) who suffered from musculoskeletal disorder complaints in the high category followed by 53 respondents (37.9%) who suffered from musculoskeletal complaints in the very high category. It was also obtained that workload significantly affected the work position variable (p = 0.000 <0.05), age significantly affected the work posture variable (p = 0.000 <0.05), workload significantly affected the musculoskeletal disorders variable (p = 0.000 <0.05), and work posture significantly affected the musculoskeletal disorder variable (p = 0.000 <0.05). Conclusion: A significant indirect effect between workload and musculoskeletal disorders complaints through work posture variables. Significant indirect effect was also found between age and musculoskeletal disorder complaints through work posture. In addition, the highest category of low back pain complaints is in moderate disability.

Perbaikan Tingkat Risiko Musculoskeletal Disorders Berdasarkan Pendekatan Nordic Body Map dan Rapid Upper Limb Assessment Pada Hasil Rancang Bangun Mesin Roasting Kopi Digital Otomatis

The roasting process of coffee beans in West Kalimantan, especially Pontianak city, is still done traditionally. The coffee roasting process is done manually by using a fire stove as a heater. Workers with standing posture stir the coffee beans continuously, and it can take 4 hours for 20 kilos of coffee beans. Standing work posture is required for stirring the coffee beans but can cause fatigue in workers due to long-standing times and high heating temperatures. This situation causes the roasting process to be less efficient and can cause the roasting process to be uneven. The purpose of this study was to identify musculoskeletal complaints of standing work posture in the manual coffee roasting process and provide an evaluation of corrective work posture when using the design results of an automatic digital roasting machine. The methods used in this study were the Nordic Body Map (NBM) and the Rapid Upper Limb Assessment (RULA) to assess the level of risk of posture for musculoskeletal complaints. The results of the identification of body points that experience fatigue were carried out by distributing NBM questionnaires and evaluating the worker's posture using RULA on CATIA V5R20. Based on the existing NBM, the risk score is 78, and the final RULA score is 6, which means that immediate corrective action is needed because the work posture is categorized as dangerous and does not meet ergonomic principles. Improvement of working posture is made by designing a roasting machine that is digital and automatic. So the workers do not need to mix the coffee beans manually. Based on roasting machine implementation results, there was a significant change in the NBM score and the final RULA score. The NBM results obtained a score of 55 which means that the risk is moderate with the risk of fatigue in the neck, right leg and, left leg. Meanwhile, evaluation of work posture based on RULA on CATIA obtained a final score of 3, which means that the work posture is not dangerous and does not require immediate improvement.

This study examines the relationship between the risk of ergonomics in work postures with material safety data sheet complaints on sampling activities. Methods: Analytical observational method with cross sectional approach. using the Nordic Body Map questionnaire and the Rapid Entire Body Assessment (REBA) assessment sheet. Primary data and secondary data were analyzed using Rank Spearman statistical test. Results: The level of risk of ergonomics in work postures at each stage of activity varies from low risk (value 2-3), medium (value is 4-7), and high (value 8 -10). Meanwhile, the level of MSDscomplaints was low (score 28-49) 11.1%, moderate complaints (score 50-70) were 44.4% and high complaints (score 71-91) were 44.4%. The results of the analysis test showed that there was a relationship between the level of ergonomics risk of working postures at 6 stages of activity, namely pre sampling, side preparation, climbing stairs, raising equipment, lowering equipment, and descending stairs (p-value < 0.05). Conclusion: Based on the other 4 stages of activity, namely sampling with a probe, sampling with a gas analyzer, measuring water content, and measuring particulate levels, there is no relationship between the level of ergonomics in work posture and complaints of MSDs, to reduce the risk of M.S.D.s complaints, efforts can be made through redesigning work stations that are not ergonomic with the use of tools to reduce workload.
