Implementation of Wet Scrubber Counter-Current System with Local Material Filters Variations on the Reduction of Dust Levels

Air is a vital element in life. However, with the continuous evolution of industrialization and technology, the quality of air has undergone transformations. Air pollutants such as dust (PM 10) significantly impact human health, leading to the development of devices aimed at reducing or controlling air pollution, such as the countercurrent wet scrubber system. The research adopts a quasi-experimental design on a field scale, utilizing a posttest with a control group. The independent variable in this study is the use of a wet scrubber with variations of local material filters, while the dependent variables are the reduction in dust emission levels. The study takes place in a working environment with dust pollutants. The population comprises dust levels in the work environment, while the sample consists of dust levels in workspaces containing dust pollutants. There are three treatments in this research, namely wet scrubbers with variations of local material filters, including eggshell, banana stem, and coconut fiber. Data are analyzed using the Kruskal-Wallis' test. The analysis results indicate a significant difference in the influence of using the three local material filters on the reduction of dust levels (p 0.000 < 0.05). Therefore, the result demonstrates distinctions among the three local material filters concerning the reduction of dust in the air.
