Analysis of air quality influenced by traffic density using web based geographic information system (Study case: Central Surabaya)

Central Surabaya is a city center where there are a lot of shopping centre and office buildings which populate the street. High traffic rate increases air pollution caused by motor vehicle, thus resulting in bad air quality for health. Carbon emission that has the biggest effect is CO and CO2, which can amplify global warming rate. The process of air quality monitoring itself, however, lacks a lot of things, especially in keeping data log and information delivery, causing inequal information spread for citizen about air pollution in Surabaya. Geographic Information System (GIS) technology, which is served in web platform, is one way to assist information delivery to Surabaya citizen about the air quality. The result of this study shows that the air quality is still good and doesn't go beyond the threshold of national ambient air quality. Primary arterial road category, Jalan Diponegoro, has highest emission rate of 1635.64 ton/year CO and 35516.32 ton/year CO2 caused by high volume of vehicle, which is 285388 smp/hour. For secondary arterial road category, Jalan Raya Darmo, has highest emission rate of 1491.72 ton/year CO and 31155.44 ton/year CO2 caused by vehicle 732395 smp/hour vehicle. Result of this study is served in web platform.
