Analysis of measurement of the working environment of machine noise in the production area in packaging factory

Abstract

Noise is an unwanted and disturbing sound that can damage comfort, work peace, hearing, blood pressure, heart rate and muscle tension. The threshold limit value (TLV) for noise in the company is 85 dB with 8 working hours of exposure. This research uses a quantitative observational method by directly observing machine noise and the noise received by workers. The way to measure noise is by using a calibrated sound level meter. The results of this research are threshold values, namely 85.7 dB and 90.5 dB. The noise is above TLV due to the many machines in one room and the additional equipment, namely blowers, on each table. However, in this situation, workers are obedient in using earplugs. Noise can cause disruption to hearing organs, workers' psychological conditions, and decreased worker productivity. This research shows that the noise condition of PT X's production area exceeds the threshold value set in PERMENAKER 5 of 2018. This research further recommends conducting safety patrols to ensure workers use earpugs or earmuffs and the use of earplugs or earmuffs correctly.
