Analisis Sebaran Kebisingan Lingkungan di Sekitar Kawasan Industri Medan 1 (KIM 1)

Abstract

Industry is one of the strategic pillars of economic growth. It can directly have a positive or negative impact on socio-economic, environmental and health aspects. Economic growth has a positive impact which results in industrial development. The object of this research is the Medan I Industrial Area (KIM I). The disturbances that are often encountered in industrial areas are noise disturbances originating from industry and transportation. The aim of this research is to analyze the environmental noise level around the Medan I Industrial Area (KIM I) against the noise level quality standards of Minister of Environment and Forestry Decree No. 48 of 1996, analyzing noise levels around the Medan I Industrial Area (KIM I), analyzing the mapping of noise level distribution patterns around the Medan I Industrial Area (KIM I) and determining efforts to control noise levels around the Medan I Industrial Area (KIM I) . This research uses quantitative and quantitative analysis methods in accordance with Minister of Environment and Forestry Decree No. 48 of 1996. The calculation results show that the highest day and night noise level (LSM) on weekdays is at point 8 (eight) of 95.28 dB(A) and the lowest noise level value is at point 13 (thirteen) of 70 .42 dB(A). On holidays, the highest day and night noise level (LSM) is also at point 8 (eight) at 94.86 dB(A) and the lowest noise level value is also at point 13 (thirteen) at 70.57 dB( A). The highest noise level mapping on weekdays is marked in red with a value range of 88.65-95.28 dB(A) and holidays with a value range of 88.19-94.86 dB(A). The noise level from the calculation results is then mapped using Arcgis and noise control alternatives such as road barriers planted with naughty vegetation (Duran repens), acacia (Acacia mangium) and trembesi (Samanea saman) at a distance of 1 meter can reduce the noise value by 0.8% and a distance of 5 meters can reduce the noise value by 1.2%.
