Abstract
This study focuses on reducing PM2.5 dust pollution in clay brick burning by using the technique of extracting smoke by installing a scrubber, studying the appropriate factors in adjusting the settings, including wind power and scrubber distance that affect the amount of PM2.5 dust, as well as checking the amount of gas after re-incineration. From the experiment, it was found that data were collected from incineration that did not use the smoke extraction technique with a scrubber for 24 hours. The data collection results from dust measurement with a sensor that measured PM2.5 dust values where the average amount reached 694.3 μg/m3 in 24 hours, which is 13.87 times higher than the standard. When the Scrubber was installed and burned again, it was found that the amount of PM2.5 dust particles decreased to a minimum of 120 μg/m3 from the analysis. P-Value found that both factors, Wind power and Scrubber distance, did not significantly affect the amount of PM2.5 dust. With a statistical confidence level R-Sq = 81.87 %
