The aim of this study was to evaluate the risk of exposure of 210 dental hygienists to forearms and wrists overloading. The study was based on a Rapid Entire Body Assessment (REBA) questionnaire. The results showed that 42.4% and 43.35% of respondents adopted a strenuous working posture of the right and left forearm, respectively. Strenuous inclination of the right and left wrist was reported by 37.1% and 43.8% of respondents, respectively. Additional twisting and lateral deviation of wrists was reported by 83.8% and 84.3% of respondents for the right and left wrist respectively. The results confirm the premise that dental hygienists are at a high risk of overloading their forearms and wrists. Therefore, there is an urgent need to implement preventive measures and to carry out periodic check-ups.

House Production

PT. X is a company engaged in the manufacture of the doll house. Its various daily production processes in each work station are performed on the floor by squatting for long hours. There are seven work stations, namely pattern making, pattern cutting, pattern assembly, caulking, sanding, painting and accessory installation. The study aims to know the risk level of working posture of operators and to suggest improvements to very risky work stations. The method used in this research is Rapid Entire Body Assessment (REBA) based on nordic questionaire on pains suffered in the back, waist, hip, right hand and foot. From the results of the collection and processing of the data, the risk of injury in an actual working system based on REBA score shows a high risk level, with the highest risk level is in caulking working station of 9 for the left side and 8 for the right side. Further, the suggested working system improvement using a chair and table results in a decrease in the risk of injury with low REBA score, the average of which is 5 for all improved work stations. It shows that the suggested working system improvement is really necessary to reduce the work risks during the doll house production.

This study aimed to systematically compare three representative observational methods for assessing musculoskeletal loadings and their association with musculoskeletal disorders (MSDs): Ovako Working Posture Analysis System (OWAS), Rapid Upper Limb Assessment (RULA), and Rapid Entire Body Assessment (REBA). The comparison was based on a literature review without time limitations and was conducted on various factors related to observational methods. The comparisons showed that although it has a significant limitation of comprising only two classifications for the leg postures, (1) the RULA is the most frequently used method among the three techniques; (2) many studies adopted the RULA even in evaluation of unstable lower limb postures; (3) the RULA assessed postural loads as higher risk levels in most studies reviewed in this research; (4) the intra- and inter-reliabilities for the RULA were not low; and (5) the risk levels assessed by the RULA were more significantly associated with postural load criteria such as discomfort, MHTs and % capable at the trunk, and MSDs.

The sustainability of the SMEs depends on how the SMEs could compete with their competitor. Utilizing technology is a way that can be used to survive in those competitions. Unfortunately, some of the SMEs in Indonesia could not afford to utilize the technology due to financial problems. Therefore, the aim of this research is to create an ergonomic working environment by utilizing the technology through the design of the press and molding machine. In its application, the concepts of Rapid Entire Body Assessment (REBA) and Rapid Upper Limb Assessment (RULA) were used to assess the working posture. The results of this assessment show that the working environment of this SME, especially in the pressing and molding process was not ergonomic and need to be improved. The given improvement is in the form of press and molding machine design and its prototype. The designing process was done using the concept of Quality Function Deployment (QFD). On the other side, to assess the level of success for the given design and machine, the REBA and RULA assessment was carried out. The results of the REBA and RULA assessment for the new machine showed that it could decrease the previous score of both REBA and RULA. The results of this research are expecting to increase the production capacity, minimizing the occurrence of MSDs, and improving the quality of the chips. In the long-term, it will be able to increase the competitiveness of this SME.

<p><em>Application of tea harvest mechanization can increase work productivity, cost efficiency, and reduce the amount of starch loss in tea leaves. The problem is that the harvester machines that are operated in most tea plantations in Indonesia are imported. The harvester machine operators have the potential to experience skeletal, muscular, and peripheral nerve disorders called Musculoskeletal Disorders (MSDs). This study aims to evaluate the design of the type GT 120 Ochiai tea leaf harvester machine based on operator anthropometry and to find the operator's working posture during the tea picking process that needs immediate improvement. Anthropometric data were collected through measurements of the operator's body dimensions, while biomechanical data were collected through video recordings of the work-movements of all operators in operating the machine with a land slope of 5<sup>o</sup> – 10<sup>o</sup>and a land slope of 35<sup>o</sup>–40<sup>o </sup>at a plant height of 75 cm to 110 cm. Data analysis was performed using the REBA (Rapid Entire Body Assessment) and OWAS (Ovako Working Posture Analysis) methods. The results showed that the design of the type GT 120 Ochiai engine was in accordance with the operator's anthropometry. The results of REBA analysis show that there is a high work risk when operating the harvester machine, namely in the land conditions with a slope of 35<sup>o</sup> – 40<sup>o</sup> with a plant height above 100 cm and when moving the sacks of the harvest to a temporary shelter. Meanwhile, according to the results of the OWAS analysis, it is necessary to take corrective action as soon as possible, namely the position of operator 3 and operator 4 and it is necessary to change the position of operator 1 and operator 2. Based on the results of the REBA and OWAS analysis, it is better if the operator’s work shift changes in machine operation with the slope of the land 35<sup>o </sup>– 40<sup>o</sup>.</em></p>

Rice harvesting is a high ergonomic risk due to the working position, an awkward posture, and the repetition activity. Rice harvesting causes body pain in the part of low back, hand, and wrist. This study aims to (1) identify the characteristics of non-mechanical rice harvesting; (2) determine the working posture of rice harvesters using the Ovako Working Assessment System (OWAS) method, Quick Exposure Checklist (QEC), Rapid Entire Body Assessment (REBA), Postural Ergonomics Risk Assessment (PERA); and (3) determine the best method to assess harvesters work posture. An observation was conducted to nine of healthy workers in Bantul and Sleman districts, Daerah Istimewa Yogyakarta (DIY) province. The questionnaire was set to collect respondent demographics data. Data for harvester body posture (neck, trunk, leg, wrist, lifting load, shoulder) repetition, duration and force were collected by observation in the field. A sickle was used to cut rice straw, while a manual gepyok and mobile hand thresher was used to threshing rice panicles. Four methods were applied to assess the work posture, i.e., OWAS, QEC, REBA, PERA methods. Based on observation, five workstations were identified: (1) cutting rice straw, (2) transporting rice straw, (3) threshing of panicles, (4) sorting, and (5) packaging and transporting. REBA and PERA showed a similar trend of the ergonomic risk, high to low risk took place in workstation transporting rice straw, packaging and transporting, cutting, and threshing. The assessment of work posture that is most suitable for non-mechanical harvesting methods was the REBA method with an accuracy of 92.9%.

The development of small and medium-sized enterprises (SMEs) is crucial for improving the economy of a rural area. However, this can cause working posture problems, such as musculoskeletal disorders (MSDs) and cumulative trauma disorders (CTDs). This is especially true for butchers, who work in SMEs that still depend on manual handling processes without standard operating procedures. Posture analysis evaluations using the Rapid Upper Limb Assessment (RULA) and Rapid Entire Body Assessment (REBA) tools have been used to analyse the working postures of butchers working in SMEs. The aim of this study was to identify butchers’ risks of working posture problems, and to propose an ergonomic workstation designed to reduce MSDs and CTDs. This study was focused on smoked meat preparation. The butchers there spend 5–8 hours a day cutting and trimming meat. The assessment was conducted using RULA and REBA worksheets. The RULA score for the meat trimming process was 7, with a score of 6 for the meat cutting process. As for REBA, the score was 5 for both the meat trimming and meat cutting processes. Based on these scores, the butchers were at higher risks for MSDs and CTDs. Therefore, a new ergonomic workstation design was proposed based on the principles of motion economy.

Background: Injuries to the scapholunate can have severe long-term effects on the wrist. Early detection of these injuries can help identify pathology. The purpose of this study was to evaluate the motions of the scapholunate joint in normal wrists in a clenched fist and through radial and ulnar deviation using novel dynamic computed tomography (CT) imaging. Methods: Fifteen participants below 40 years of age consented to have their wrist scanned. Eight participants were randomized to have the right wrist scanned and 7 the left wrist. Volunteers were positioned at the back of the gantry with the wrist placed on the table, palmar side down. Participants began with the hand in a relaxed fist position and then proceeded through an established range of motion protocol. Dynamic CT imaging was captured throughout the range of motion. Results: The movement in the healthy scapholunate joint through a clenched fist and radial and ulnar deviation is minimal. The averages were 1.19, 1.01, and 0.95 mm, representing the middle, dorsal, and volar measurements, respectively. Conclusions: This novel dynamic CT scan of the wrist is a user-friendly way of measuring of the scapholunate distance, which is minimal in the normal wrist below 40 years of age.
