Analysis of Musculosckeletal Complaints Disordered With Reba Method and Rula Method

Abstract

Class furniture, namely tables and chairs, are significant physical facilities because the furniture is used for teaching and learning activities. Pain in the neck, waist, right upper arm, right forearm and right wrist during the learning process due to non-ergonomic facilities. Therefore, this research aims to minimize the complaints of Musculoskeletal Disorder with the Ergonomic Learning Chair. In this study, descriptive research with the REBA method and the RULA method was used. With the REBA method, the final score obtained in Group C is 8, then this value is entered at Action Level 3, after which researchers can only find out that the student's body posture level is in the High category so that action is needed immediately. With the RULA method, the student's body activity results are at a Group C score of 7. The value is entered for Action Level 4 so that the student's posture is in the dangerous category for safety, health and comfort. Therefore, action is needed now to overcome this problem with the suggestion manufacture of Ergonomic Study Chair. From the results of the chair use test design analysis by distributing questionnaires to 35 students as a sample, it was found that there was a decrease in complaints of Musculoskeletal Disorder in the student body. With the contribution of the study table, it can be adjusted up and down (adjustable) to make the chair more comfortable.

Risk of Musculoskeletal Disorder in the Working Posture of Online Motorcycle Drivers (Case Study: Drivers at Malang District)

“…Case studies are an effort to investigate by conducting surveys and historical processes to explain cause -effect. The survey was conducted on gojek drivers within the scope of ergonomics topics, namely musculoskeletal disorders [4,[12][13][14][15]. The process in this study is to determine the location and time of the study, identify samples using inclusion and the number of respondents used, measure the working posture of riders with 3 types of motorcycles using RULA-REBA sheet and Nordic body maps questionnaire.…”

“…Then focus on determining the value of the upper arm, forearm and wrist, neck, spine and legs using the integration of Rapid Upper Limb Assessment and Rapid Entire Body Assessment. Wargiono et al [4] have the number of respondents < 10 people. This is a research gap where the prevalence will be carried out to 30 respondents with an assessment of 3 different types of vehicles, namely supra-125, v-ixion and vario-125 [4][5][6].…”

Kee et al stated that reducing musculoskeletal disorders by reviewing how much work risk and level of interest in work comfort are important indications [7][8][9][10][11].…”

Analysis and Assessment of Passenger Comfort Level in Sustainable Public Bus Transportation System

“…The assessment starts from the smallest scale of 1 to the highest of 11, where the obtained value represents the risk of injury that could affect passenger comfort and safety. RULA (Rapid Upper Limb Assessment) is also one of the most effective methods to measure passenger body upper posture [10]. RULA uses the same method of assessment and calculation to determine passenger body structure point as REBA.…”
