The Analysis of Noize Hazard towards Workers in Booster Pump Location of PDAM Tirtanadi Medan, Indonesia

Abstract

The noise sound can be potentially arisen by the usage of machine and work tools that support the production process. PDAM Tirtanadi is a company runs provincial water supply engaged in the drinking water processing. However, the machine and tools of the company can generate the noise. Thus, the paper aims to find out the noise intensity of 5 points measurement in booster pump, then determines the correlation towards communications disruption, psychology and physiology. Then, the sound pressure level measurement method refers to Indonesian Minister of the Environment Decree Number 48 Year 1996, and the sound level meter was utilized as means for the research. The result shows that the noise intensity gained of 5 points passed the noise Threshold Limit Value (TLV) as much 96.40dB - 96.75dB. Moreover, the noise level has a significant influence towards the communications, psychology and physiology disruption, which the R value of multiple correlation as much as 0.884.
