Abstract

Akheng Kobar is one of the small and medium enterprises (SMEs) that is growing, which produces concrete blocks manually. The brick making process has an ergonomic problem, because the posture of workers in a squatting and bending position for a long time during work. Based on interviews with workers, there were complaints of pain in the back, arms, wrists, calves and thighs. Other complaints include the neck, hands and ankles. In this study, an analysis of initial working conditions, tool design, implementation and results analysis were carried out. Analysis of current conditions using REBA (Rapid Entire Body Assessment), obtained a score of 11, and the JSI (Job Strain Index) analysis score was 39. The results indicate that the process of bricks production must be changed and improved. Furthermore, it was carried out to design a concrete brick press, with the aim of reducing the level of ergonomic risk and increasing productivity. Tool design based on operator complaints, body posture analysis and anthropometric data. Of the several alternatives, obtained the best design alternatives and then made a prototype. Implementation results show a decrease in REBA Score from 11 to 7. Ergonomic Risk Factor decreased from 9 to 5, Job Strain Index scores decreased from 39 to 6.8, and standart time of process decreased by 44,38%.
