Traffic Noise Level Analysis in PGC and Cawang Baru

Abstract

This study aims to measure and analyze noise levels in two areas with heavy traffic in Jakarta, namely Pusat Grosir Cililitan (PGC) and Cawang Baru. These locations were selected due to their strategic role as transportation hubs with high vehicle volumes, contributing significantly to increased noise levels. Measurements were conducted from Tuesday to Friday, at 16.00 -18.00 WIB, with each observation session lasting 10 minutes, using four applications: Sound Level Meter, Sound Meter, Sound Measurement, and Sound Meter dB, to ensure data accuracy and validity. The study results show that noise levels at PGC ranged from 78.5 dB to 83.1 dB, while at Cawang Baru, noise levels ranged from 80.2 dB to 85.9 dB. The highest noise fluctuations were recorded on Friday, making Cawang Baru the location with the highest noise levels during the study period. Based on government standards that set the noise threshold at 70 dB, both locations consistently exceed this limit. The high noise levels were primarily due to high vehicle volumes, including heavy vehicles, and frequent traffic congestion in both areas. This study confirms that areas with high traffic activity, such as PGC and Cawang Baru, experience significant noise levels, potentially causing severe health impacts, including hearing loss, stress, and sleep disturbances. Therefore, mitigating measures are necessary to reduce noise, such as limiting heavy vehicle operating hours, implementing vehicle-free zones at certain times, and using soundproofing technologies. These measures are crucial to protect public health and create a more
comfortable and healthier environment.
