Analisis Spasial Tingkat Kebisingan Aktivitas Transportasi (Studi Kasus: Persimpangan Jl. Sisingamangaraja – Jl. A. H. Nasution Kota Medan)

Abstract

The source of road traffic noise comes from motorized vehicles, both two-wheeled, four-wheeled and heavy vehicles. This study aims to determine the noise level at the intersection of Jl. SM Raja– Jl. A. H. Nasution Medan City and determine appropriate controls to reduce noise levels. The measurement method used refers to KepMenLH No. 48 of 1996. Vehicle speed measurements and traffic volume calculations are carried out on holidays and weekdays at 31 measurement points. The results of the sampling were mapped using Surfer version 15 and determined the noise control efforts at the Jl.SM Raja–Jl. A. H. Nasution Medan which is superimposed with a screenshot of the google maps map. The results obtained from the noise level ranged from 71.3 dBA - 85.2 dBA on holidays and on weekdays obtained a noise level of 79.3 dBA - 85.3 dBA. Based on the mapping with Surfer 15, the highest noise level was obtained at point 1. The recommended noise control alternatives such as planting 1.2 m tall plants with 16.65 m2 of vegetation, installing brick walls as high as 2.8 m, regulations on honing the horn, diverting the flow of rickshaw traffic on weekdays and vary the receptor safe distance with the noise source.
