Analisis Waktu Kebisingan PT. Riau Power Unit PLTG/U Pekanbaru Dengan Metode Noise Mapping

Abstract

The Research has been conducted to determine the the noise’s intensity
from operational activities originating from generating machines at PT. Riau
Power Unit PLTG / U Teluk Lembu Pekanbaru with the Grid method. Workers
who are constantly exposed to noise have the potential to affect workers' health
and comfort. The purpose of this study was to determine the intensity of noise
generated by the generator engine, the length of exposure time, mapping the noise
distribution patterns, and noise control efforts. The noise measurement method
refers to the noise mapping method and the instrument used is a Sound Level
Meter (SLM). The measurement of sound pressure level took place for 1 day. The
results showed that from 97 measurement spots there were 40 spots indicating
numbers that exceeded the quality standard. The highest loudness level is 106.1
dB where this spot located very close from the noise source, and the lowest
loudness level is on 59.5 dB where the distance is quite far from the noise source.
The planned noise control attempt is by using noise barrier (naturally or
artificially), isolate the machines, machine care, the administration management,
and the human resource management by applying a vertical garden to the office
building.
