Investigation of CO emissions on school areas based on Caline-4

Abstract

Abstract The school located near the city’s main transportation line at first profitable for the school because the location is easy to reach. From the location of the school is considered strategic but not fit with convenience of studying in school, the problem arises that the location close to the main road tends to have a higher level of air pollution and leads to impact the students at school. The purpose of this research is to know the level of carbon monoxide at the school area uses modelling CALINE-4 and the pattern of distribution of emission CO at school area with CALINE-4. This research was done in three locations for three days namely MAN 2 Model Makassar, SMA Negeri 11 Makassar and SMP Negeri 4 Makassar. Analysis of the distribution of Carbon Monoxide CO emissions using Caline 4. The largest result of Carbon Monoxide (CO) pollutants in MAN 2 Model Makassar at 05:00 pm, namely the b receptor is beside the school at as much as 9 ppm. In SMAN 11 Makassar, the biggest carbon monoxide (CO) pollutant was at 07:00 pm the two receptors in front of the school as much as 2.2 ppm. And in SMPN 4 Makassar, the biggest carbon monoxide (CO) pollutant was at 06:00 am the receptor in front of the school as much as 3.1 ppm. The pattern of distribution of CO concentration is influenced by the wind speed and wind direction affecting the pattern of the distribution of these pollutants. The faster the wind blows, the spread of pollutants is faster with a wide range.
