Konsentrasi Polutan Udara Ambien Sekitar Kawasan Industri Kecamatan Madidir Kota Bitung

Abstract

Industrial activities have the potential to pollute the environment, including air pollution from smoke and dust, which can result in a decline in air quality. The aim of the research is to examine the ambient air quality around the industrial area of Madidir District, Bitung City. The descriptive observational method is used to collect data and analyze the measurement results. The measurement of ambient air particulate concentration samples was taken from several locations using passive samplers (diffusive sampling). This measurement technique involves the use of absorbent materials to capture air pollutants over a certain period, which are then analyzed in a laboratory, and the results are compared to quality standards. The research results show that the average concentration levels of particulates (SO2, NO2, TSP, CO, H2S, NH3, and Pb) at the locations in the Madidir Unet, Paceda, and Wangurer Timur villages are below the quality standards. Other findings indicate that there are 2 TSP samples with high concentrations out of a total of 6 samples, namely sample 2 in Madidir Unet Village, at 233 µg/Nm³, and sample 3 at 204 µg/Nm³ in Paceda Village, which are significantly higher than the other samples, but these values are still below the quality standard. TSP is often found in high concentrations in urban and industrial areas, as well as construction and transportation activities. Therefore, to maintain and improve air quality, continuous monitoring and enhanced emission control from pollution sources are necessary to prevent and ensure that pollutant concentrations remain within safe limits.
