Abstract

Background. The problems found in CV Diamond Cabinetware stem from the fact that all production activities for furniture and door handles are carried out using human labor, assisted by several machines. The factory's machines include bending, pounding, stamping, drilling, grinding, and hand shears. Aim. This study evaluates the current work system and designs ergonomic improvement solutions to reduce the risk of musculoskeletal disorders (MSDs). Data were collected through direct observation, semi-structured interviews, and workers completing the Nordic Body Map questionnaire. Methods. The risk analysis was carried out using the Rapid Entire Body Assessment (REBA) method, and the results showed a high level of ergonomic risk at specific workstations. Results. Based on the analysis results, improvements were made to ergonomic chairs and tables using SolidWorks software. Proposed improvements were evaluated through Human CAD simulations using CATIA V5 to assess the effectiveness of the design in reducing the risk of injury. Conclusion. The study's results show that the proposed ergonomic design has improved work posture, reduced physical stress, and improved employee comfort. Implementation. This study makes an essential contribution to the application of ergonomics in small-medium industries and is expected to be a reference for developing healthier and more productive work systems.

Abstract

Background. PT Rentang Buana Niagamakmur is a spring mattress manufacturing company that faces a decrease in productivity due to worker discomfort and ergonomically suboptimal working postures Purpose. This study aims to identify the causes of workers' physical discomfort in the production process and design work aids that can improve comfort and productivity. Method. The research process began with data collection through observation and interviews to understand the activities of workers at the production station. The Nordic Body Map (NBM) was employed to identify workers’ musculoskeletal complaints, while Rapid Entire Body Assessment (REBA) was applied to evaluate ergonomic risk levels. Results. Based on the results of the analysis, the design of work aids was carried out using an ergonomic approach that suits the needs of workers at fabric measurement and foam cutting stations. Evaluation of the effectiveness of the aids was carried out by comparing REBA scores before and after the use of the aids. Conclusion. The results showed that the main physical complaints of workers were identified in the right wrist, waist, and calf. The design of work aids at the fabric measuring station lowered the REBA score from 11 to 3 (low risk), while the aids at the foam cutting station reduced the score from 7 to 3 (low risk). Implementation. The proposed work aids were shown to significantly reduce physical discomfort and improve productivity at both workstations.
