The impact of transportation growth on the increase SO₂ and NO₂ gases in Surakarta City during 2013 - 2020

Abstract

The city of Surakarta has experienced a population growth of 2.42% since 2010 which has an impact on increasing public needs in the transportation sector. The increasing number of transportation in Surakarta City can causes various kinds of problems, one of which is increase air pollution of SO2 and NO2. This study aims to determine impact transportation developments on increase in air pollution of SO2 and NO2 gases in Surakarta City during 2013 – 2020. Research method using regression calculation to determine the effect of transportation growth on the accumulation of SO2 and NO2 gases and time series analysis. The time period is 2013 – 2020 in Surakarta City by determining 20 monitoring points to obtain SO2 and NO2 gases data collected using the passive sampler method. The results obtained indicate a fluctuating increase and decrease in SO2 and NO2 gases during the period 2013 – 2020. Total amount of SO2 gas collected during 2013 – 2020 was 2095.67 g/Nm3 with the highest amount being in 2014 at 353.72 g/Nm3, while the total amount of NO2 gas collected during 2013 – 2020 Overall it was 2202.64 g/Nm3, the highest was in 2014 which was 416.07 g/Nm3. The impact of transportation growth on NO2 gas is 89,4% during 2013 - 2020, while for SO2 gas there is no significant effect.
