Study of traffic noise at elementary school Pondok Cina 1 Depok, West Java

Abstract The study aims to analyze the level of traffic noise in the area of Pondok Cina 1 Public Elementary School and analyze the V/C ratio of the main road in front of the school area. The method of measuring noise levels is carried out by the Decree of the Minister of Environment No. 48 of 1996. The data is then processed for the value of each road adjustment factor adjusted to the relevant road conditions by the Indonesian Road Capacity Manual (MKJI). The results showed that the level of traffic noise in the school area ranged from 78.56 to 90.00 dBA. Compared with the results of these measurements, it is evident that the noise level has exceeded the quality standard. Furthermore, based on the calculation of traffic volume and road capacity, the V/C ratios are ranged from 1.23–1.62 which later categorized in the service level F. Road with this level of service has jammed traffic flow, vehicles at low speed, long queues, and large obstacles occur. To avoid having an impact on school activities, it is necessary to control traffic noise in the school area by creating noise barrier.
