Working conditions with production targets, high accuracy and precision, long working hours and high noise disturbance (>85 dB) on the production floor puts pressure on workers in a weaving factory in Tangerang, Banten Province. These conditions can trigger mental workload and reduce workers’ cognitive function, impacting product accuracy. This study aims to see the relationship between noise level with mental workload and operator reaction time. In this study, the operator’s reaction time is an indicator of workers’ cognitive function. The research was conducted on 30 workers from three different divisions, reaching, finishing, and weaving. Noise level measurement is conducted using sound level meter app, mental workload measurements using the NASA-TLX questionnaire, and reaction time measurements by measuring responses to visual stimuli in the form of different colored light. The measurement results show that the noise level received by workers in the three production divisions ranges from 82.7 dB to 101.6 dB. This result indicates a loud noise level. The measurement of mental workload results produces an average NASA-TLX score of 74.4, which indicates a high mental workload. Measurement of reaction time in conditions before and after work showed a significant difference in results, where there was a longer reaction time after work. This long reaction time indicates a decline in cognitive function in workers. The relationship between noise level with mental workload and reaction time was measured using the Pearson correlation test. The results of the Pearson correlation test show that the noise level has a significant relationship with mental workload, and reaction time.
