“…Many previous studies have summarized and compared the three techniques, based on their general characteristics including correspondence with a valid reference, scales for posture classification, main functions, association with MSDs, intra- and inter-observer repeatability/reliability, potential users, and exposure factors assessed such as postures or body regions, load/force, and movement frequency [ 5 , 15 , 16 , 17 , 19 , 20 ]. Some studies compared the three methods based on their assessment results [ 12 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 ], and the relationship between the epidemiological data or subjective symptoms of MSDs and assessment results or scores [ 27 , 28 , 29 , 30 , 31 , 32 , 33 ].…”

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.

“…After the working postures have been identified, the effects on the musculoskeletal system by the postural load are then evaluated. The OWAS action category is an ordinal scale but is applied to quantitative statistical analysis assuming an interval scale as with the RULA grand and REBA scores for comparing the three techniques (Kee et al, 2020). OWAS by evaluating posture divided into 4 segments, namely back, arm, leg, and weight load.…”

“…OWAS was designed to be easy to use and is therefore accessible to ergonomically untrained personnel. Even though it uses a simplified sampling technique, OWAS provides reliable and valid results (Brandl et al, 2017;Kee et al, 2020).…”

The appointment of catering dishes at Dian Rasa Catering is currently still done manually by hand. Slouching work posture when lifting plates increases the risk of muscle and spinal injuries in workers. One way that can be done is to design ergonomic plate lifters. The design of an ergonomic trolley uses the Ergonomic Function Deployment (EFD) method. The attributes used are based on ergonomic aspects, which are effective, comfortable, safe, healthy, and efficient. Based on the attributes used, it can be seen the desires and needs of consumers for products which are then integrated with the technical characteristics of the tool. Obtained the results of the design of a catering plate lifter in the form of 3 plate racks with a radius of 21 cm that can accommodate 20 plates and trolleys with a height of 125 cm and the size of the trolley handle that can be adjusted according to the smallest body size (118 cm), on average (125 cm)) and maximum (132 cm). The results of the experimental an ergonomic trolley help the employee to lift the plate, improve time efficiency and reduce the risk of muscle and bone injury to the catering employee. After the use of plate lifting tools catering harvest workers labor posture scores using the OWAS method dropped to 1.

“…The use of RULA and REBA assessment made the analysis of work posture are easy and reliable. Moreover, Kee et al (2020) stated in their research that RULA is the best technique that could be used for assessing the working posture. On the other hand, some of the research also highlighted the use of this method if it will be used alone or combined it with other method.…”

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.
