Slouching and squatting work postures in the fish cleaning process can cause skeletal muscle injury. Based on the results of previous research conducted by Adelia (2020), the results of the existing NBM show that workers have complaints in the muscles of the neck, arms, back, waist, buttocks, hands, wrists, thighs, knees, and feet. The result of total muscle complaints individual skeletal is 75, meaning that the existing work posture requires work improvement. Improvement of working posture can be done by designing work aids in the form of desks and chairs. The determination of the MSDs risk level category was carried out by identifying the skeletal muscle complaints felt by workers using a Nordic body map (NBM) questionnaire, a working posture assessment was carried out to determine the score level in work posture using the Rapid Upper Limb Assessment (RULA) method with the help of CATIA V5R20 software. Assistive devices in the form of desks and work chairs are designed based on complaints experienced by workers and use the anthropometric approach in determining the dimensions of work aids. Based on the results of the implementation of work aids, there was a change in the score for skeletal muscle complaints and work posture. The results showed that the average NBM value of individual muscle complaints was 56.75, this is included in the moderate risk level and the results of the RULA analysis on the repair work posture experienced a change in the final score, namely 4 (yellow).

Coffee Roasting

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.

Traditionally, there have been two methods for measuring total muscle glycogen (Glytot), either by acid hydrolysis (AC) or by enzymatic hydrolysis (EZ). As well, it has been determined that rodent muscle contains two pools of glycogen, macroglycogen (MG) and proglycogen (PG). This MG/PG determination of Glytot has never been compared with AC or EZ methods, nor has it been determined whether the two pools exist in human skeletal muscle. A detailed comparison of the three methods was performed by using both rodent and human muscle. It was found that repeated analysis of independent portions of muscle generally gave coefficients of variation of <10%. The PG fraction was always in excess of MG, which was 6–10% of Glytot in rodent muscle and in human samples when Glytot was low but increased to ∼40% when Glytot was high. It was found that AC and EZ Glytot were not statistically different ( P < 0.05), nor was there a difference between the MG+PG Glytot and that determined by AC or EZ. The Glytot from MG+PG extraction had a strong correlation with the values obtained by either AC ( r = 1.0) or EZ ( r = 0.96). These data suggest that MG+PG do exist in human skeletal muscle and can be measured reliably in biopsy-sized samples. All three methods give an accurate representation of human Glytot and are comparable in their precision.

Occupational health and safety allows the prevention of occupational diseases and accidents. Agriculture is one of the sectors in which it is important to prevent the musculoskeletal disorders that workers usually develop. The objective of this study is the evaluation of postures adopted by courgette farmers in greenhouses of the Almeria-type. OWAS (Ovako Working Posture Assessment System), an ergonomic evaluation method, is used and applied after making observations to the postures adopted by the workers who were previously video recorded. The results concluded that the four risk levels established by OWAS appeared, with 37.14% being the highest rate and belonging to risk level 2, 33.33% to risk level 1, 28.57% to risk level 3, and 0.95% to risk level 4. Therefore, depending on the severity of the postures adopted in each task, the need for changes in a short, medium, or long period of time was concluded.

Based on the REBA analysis, there is a risky operator work postures in the warping work station at PT. Iskandar Indah Printing Textile because they do not use work tools. The assessment of the level of work posture risk by the REBA method gets the result that the highest work element with a final score of 10 is obtained by taking warp yarn at the warping station. This study aims to produce a design tool to reduce the level of work posture risk in warping work station operators. Then the design of tools was carried out by the Pahl and Beitz method to produce three alternative product design concepts. Based on the three ideas, the best plan is chosen by using an Engineering Design Selection, and the result is the second design concept. The selected design is an adjustable trolley with a vertical screw drive system that is comfortable to use and does not cause a bending position on the operator because it has a trolley plate that can be adjusted in height as needed. The use of the trolley causes a decrease in the level of work posture risk from a high-risk level to a small risk level with a final score of 10 to 3.
