Abstract

The air contamination which is caused are generated by human activity it self, one of them is transportation appliance. Motor cycle is one kind of the transportation appliance which is often met. One of type air pollutant which is produced by motor cycle is CO gas. CO gas can cause decreasing the ability of the body in receiving oxygen so that can cause O2 rate become decreasing, because CO gas fasten hemoglobin so that the hemoglobin fasten O2 decrease. Explanation in the long time will cause bronchitis, emphysema, and lung cancer. The strive to handle CO gas can be done by adsorption using the gypsum. Gypsum represent evaporate mineral that having the porosity and have very smooth surface, so that the absorption happen in many place. The variable which is learned in this research is the gypsum length ( 5, 10, 15, 20 and 25 cm ), detention time ( 30, 60, 90, 120, and 150 minute ) and the sum up hole ( 10 and 20 pieces ). The result which is obtained from this research, are gypsum length 25 cm, with the time on it 150 minute and the sum up the hole 20 pieces that producing CO gas exclusion equal to 30,32 %.
