Abstract :
Over the past decade, carbon monoxide (CO) emission has risen due to the increase of vehicles. Bogor, a tourist
destination city on weekends, has a heavy burden in terms of vehicle volume. The object in this study is
Baranangsiang Bogor toll gates where queue of motor vehicles often occurs and allegedly produces many pollutants
including CO. The goal of this paper were to simulate and validate the CO concentration in ambient air in the
vicinity of Baranangsiang toll gates by the method of Finite Length Line Source (FLLS).Measurement of CO
concentration was carried out using impinger. It was followed by CO concentration analysis referring to National
Standard, namely SNI No. 19-4848-1996 on Pentoxide Method. Based on the results of direct field measurements
and simulations that were conducted on four sampling points within 20 m and 190 m away from the pollution
sources on August 26thto September 1st2013, CO concentration, i.e. 634 - 9189 ?g/Nm3 was still within the range of
pertinent standards in accordance with Government Regulation No. 41/ 1999. CO pollutant was dominantly
dispersed to the East with measured wind speed of 0.3-4 m/s and atmospheric stability class B. Consequently, a
settlement area called Kampung Sawahlocated in the Eastern side of the toll gate was exposed to higher CO.
