Abstract

Airplanes are modern transportation that can travel very long distances with a short time. However, the increasing number of flights that operate will be directly proportional to the pollution produced by aircraft jet engines. One of the gas emissions from the aircraft is carbon monoxide (CO) gas. Carbon monoxide gas in high concentrations can cause health problems in humans and can even cause death. Mathematical modeling can be used to determine the concentration of pollutants and predict their distribution. By using the Gaussian Plume model we can predict the distribution of CO concentrations produced from the combustion of aircraft engines operating at airports. From the results of the Gaussian Plume model, the concentration of carbon monoxide emissions at various points was obtained. The biggest dispersion of emissions is 635.751 µg / m3. Hours at a distance of 4.425 km from the source of emissions. After taking an ambient measurement, the performance of the model reached 35%, while the ambient CO concentration at the study site showed a greater value than the model value.
