Abstract
The study aims to make efforts to control air pollution that occurs due to the operation of PT. Semesta Indonesia Alam Raya. This company is an andesite mining industry located in Pucang Gading Hamlet, Hargomulyo Village, Kokap District, Kulon Progo Regency, Yogyakarta Special Region and then processing the andesite into the split. Split is one of the construction materials used in the casting process. At the operational stage of PT. Semesta Indonesia Alam Raya, namely the processing of andesite into split stone crusher tools, will have a negative impact, namely an increase in the amount of dust flying around the factory site. Having a wind blowing will help spread the dust in the direction the wind is blowing. If this condition is left unchecked, it will result in the direct impact of decreasing air quality around the factory site, and this will have a secondary impact. It’s namely a decrease in the level of public health, one of the indicators is the increasing number of people suffering from ARI, a disease related to breathing. Therefore, it is necessary to control dust pollution by capturing dust that comes out of the stone crusher along with the exhaust gas flow. This research uses a simulation of fogging method dust capture equipment, which is carried out in the laboratory. The independent variable is the nozzle diameter in the sprayer, while the other quantities are the dependent variable. In this independent variable, a study was conducted on five quantities, and each quantity was carried out three times repetitions, then the results were averaged. After conducting the research, the data obtained from the research results show that the optimum condition for the dust mass of dust that is caught by the fog is a nozzle diameter in the sprayer with the average mass of dust that can be caught by the fog is 13,877.33 μg and the average efficiency value is 74.38%. The line equation that states the relationship between the variable nozzle diameter and the mass of dust caught by the fog is Y = -27.779X3 -452.7X2 +3,600.7X +7758.8 with a percent error of 0.58%, while the line equation states the relationship between variables the nozzle diameter in the sprayer with an efficiency value, namely Y = -0.1458X3 - 2.5075X2 + 19.708X + 41.19 with an average percent error of 0.31%. It is hoped that the use of this dust catcher can control the spread of dust to the environment. Keywords: Control, Dispersion, Dust, Fog
