Abstract
Purabaya Terminal was one of the busiest terminals from August 1 to October 18, 2023, with 56,347 bus arrivals and 54,533 bus departures, so it is necessary to monitor air quality, one of the parameters of which is Nitrogen Dioxide (NO2). The change in air quality is influenced by factors such as the large volume of bus public transportation and meteorological factors such as temperature, humidity, and wind speed. This study aims to determine the concentration of NO2 at Purabaya Terminal and to determine the influence of the volume of public buses and meteorological factors on the increase in NO2 concentration, as well as to analyze the level of health risk of respondents who sell stalls. The study was conducted at 3 points with sampling times in the morning at 08.00-09.00 WIB and in the afternoon at 16.00-17.00 WIB. The research was conducted for 4 days from October 21-24, 2023. The results showed that the highest NO2 concentration was recorded at point 2 on Sunday morning October 22, 2023 at 140.47 μg/m3 and the lowest NO2 concentration was recorded at point 1 on Saturday morning October 21, 2023 at 15.41 μg/m3 so that the highest ISPU value was recorded at 75.20 in the moderate category. In this study, the NO2 concentration is still below the ambient air quality standard of PP No. 22 of 2021 of 200 μg/m3 for a measurement time of 1 hour. The results of multiple linear regression statistical tests obtained the equation Y = 42 + 0,737 X1 + 0,42 X2 + 0,03 X3 – 34,1 X4 where the increase in NO2 concentration (Y) is influenced by an increase in the volume of public bus transportation (X1), an increase in temperature (X2), an increase in humidity (X3), and a decrease in wind speed (X4) with an error rate of 48.56%. The results of the ARKL calculation show that the health risk level of 50 respondents to NO2 concentrations obtained an RQ value < 1 so that respondents are declared not at risk or safe.
