Ergonomic tetrapod reduces the MSDs risk and productivity of steel-bar assembly for reinforcement concrete beams

Abstract

The digitalization of construction has been carried out to meet the demands of the industrial era 4.0. However, there is still a lot of construction work that is preform manually, such as the steel-bar assembly for reinforcement concrete beams. Based on the 2019 ILO report, it can be seen that fatal work-related illnesses reached 86%, much higher than work accidents, which was 14%. Of the various fatal illnesses due to work, MSDs requires the highest health compensation costs, which reach 40%. The previous study showed that the steel-bar assembly was done in awkward working posture (squatting, bending, twisting repeatedly) with high risk of MSDs (Rula score: 7) and needs improvement immediately. This research was conducted through experiment with pre-posttest control group design. The specific target of this research is to reduce the MSDs risk and increase the productivity by supporting the workers with the ergonomic tetrapod as the working table. The subjects were two groups of students at Civil Engineering Department Politeknik Negeri Bali, with 14 students in each group.

Analysis of The Use of 12 Kg LPG (Liquified Petroleum Gas) Conveyance to Complaints of Household Workers

“…The results of the analysis after using the 12 kg LPG conveyance showed a difference (p>0.05) and a decrease in musculoskeletal complaints from the average score of 80.1 to 70, or a decrease of 12.6%. In line with what was stated by Lilik [12], Santosa [13], and Yusuf [14], they stated that the practice position of standing and bending is the wrong position in working especially when using equipment will cause musculoskeletal disorders. Musculoskeletal complaints experienced by housewives are on the back, waist, both knees, and calves.…”
