Abstract


Karangrejo Raya street, Sukun Raya street Ngesrep Timur V street of Semarang are located at the intersections in Banyumanik. All streets located at the traffic lighted intersection which caused the vehicles have to stop at the red light that causing the increasing of CO. The otther factors that affect the concentration of CO is the meteorological factors,  temperature, humidity, and wind speed. The method of this study is  direct sampling at sampling locations using a CO Meter, Anemometer, Hand Tally Counter and Compass. Sampling was conducted in rush time. The concentration of CO in the Karangrejo Raya ranged from 8 ppm - 14 ppm, the concentration of CO in the Sukun Raya ranging from 8 ppm - 17 ppm, and the concentration of CO in the Ngesrep Timur V 8 ppm - 19 ppm. The relation of the number of vehicles and the air humidity is directly proportional to the concentration of CO that will gain along with the increasing number of vehicles and humidity, while the air temperature and wind speed which is inversely proportional to the concentration of CO that is getting decreased when the air temperature and wind speed are getting in creased as well.
