Analisis Pengaruh Pembangunan Underpass Terhadap Tingkat Kebisingan Di Jalan Jawa, Kecamatan Medan Timur

Abstract

Analysis of the Impact of Underpass Construction on Noise Levels on Jalan Jawa, East Medan District The construction of underpasses in order to alleviate congestion causes changes in traffic volume on each affected road. Not only that, the construction of the underpass will cause noise impacts starting from the construction to operational stages. In the construction phase, activities that become potential noise generation start from land clearing, mobilization of heavy equipment and materials, earthwork etc. The Medan City Government is building an underpass on HM Yamin road at the Java road intersection, Medan City. The method used in this research is primary data collection (field measurements) then data processing using quantitative and qualitative data analysis and mapping using GIS applications. The results showed that the highest day and night noise level (LSM) value on weekdays was at point 8 (eight) of 81.35 dB(A) and the lowest noise level value was at point 13 (thirteen) of 57.00 dB(A). On holidays, the highest day and night (LSM) noise level values are also at the same point. According to the mapping results on weekdays there are all points that exceed the quality standard, as well as on holidays also all points exceed the quality standard set by Kepmen LHK No. 48 of 1996 in industrial areas which is 60 dB (A). Mapping of noise level results on weekdays is marked in red with a value of 75.39-79.29 dB(A), orange with a value of 71.39-75.39 dB(A), yellow with a value of 67.60-71.39 dB(A), light green with a value of 59.80-63.70 dB(A) and dark green with a value of 63.60-67.60 dB(A).
