Analisis Konsentrasi dan Dispersi Gas Carbon Monoksida (CO) pada Kegiatan Industri Pengasapan Ikan dengan Pendekatan Model Gaussian Multiple Source

Abstract

This research was conducted at the fish smoking center in Desa Koto Mesjid, Kecamatan XIII Koto Kampar. The smoking activity uses firewood as fuel to produce smoke. The results of worker interviews from 45 respondents, as many as 18 people with sore eyes and 16 people with dizziness. It is necessary to conduct research to determine the concentration of CO gas and its distribution as well as the impact on workers and the environment. The study was conducted on 8 groups of fumigation businesses to calculate CO gas emissions with the fuel approach used, then analyze the dispersion and impact as well as measure the concentration of CO gas and compare it with quality standards. Calculation of pollutant concentrations using the Gaussian Multiple Source model, sampling of air quality in the field, testing the validity with the Wilmott's Index, and comparing the results of direct measurements with the PP No. Quality standard. No. 22 of 2021. Observations of the highest CO gas emission load were 8.511.314 g/sec, and the highest amount of fuel wood consumption was 17.696 kg/day in the Rezky Salai business group. The Gaussian dispersion approach obtained the results that the concentration of CO gas dispersed at the office, musholla, and canteen receptors was 1.287 μg/m³, 3.938 μg/m^3, and 8.302 μg/m³, while the maximum concentration of actual CO gas measurements was 4.908 μg/m³, 9.077 μg/m³ and 9.204 μg/m³. The actual measurement results still meet the quality standards, with values ​​below 10.000 g/m3. The validation of the Gaussian modeling results with the Wilmott's Index resulted in the d value of the office = -0,140, the d value of the Musholla = -0,149, and the d value of the Canteen = -1,278. The value of d in Wilmott's Index indicates that the Gaussian model cannot be applied to the CO gas dispersion in this fish smoking center.
