Abstract : Abstract:-This study aims to determine the influence of ergonomic chair improvements on Musculoskeletal Disorders (MSDs) complaints and productivity among sewing workers at PT X. The research population consisted of 30 workers in the sewing department using a sampling technique. This study employed an analytical quantitative design with a cross-sectional approach conducted at Company X. The sample size was 30 workers, selected through random sampling. Data collection involved anthropometric measurements, pre- improvement assessment of work chairs, the provision of ergonomic chairs tailored to the workers' anthropometry, and the use of the Nordic Body Map questionnaire to assess musculoskeletal complaints. Data processing and analysis were performed using the nonparametric Wilcoxon test in SPSS version 16.0. The analysis of the difference in musculoskeletal complaints before and after the intervention using the Wilcoxon test yielded an Asymp. Sig (2-tailed) value of 0.000 (p value 0.001 < 0.01), indicating a highly significant result. The analysis of the difference in total productivity before and after the intervention using the Wilcoxon test resulted in an Asymp. Sig (2-tailed) value of 0.004 (p value 0.004 < 0.05), indicating a highly significant result. In conclusion, this study demonstrates that there is an influence of ergonomic chair improvements on musculoskeletal complaints and productivity among sewing workers at PT X.
