The Effect of the COVID-19 Pandemic on Ambient Air Quality in Yogyakarta Urban Area Parameters SO2, CO and, NO2with Inverse Distance Weighting (IDW)

Abstract

In early March 2020, a pandemic disrupted human activities, especially in the Yogyakarta Urban Area. The area is experiencing development or becoming a tourist center in the Province of the Special Region of Yogyakarta. With these developments, this study would carry out data processing related to air quality, remove it comparing the concentration of SO2, CO, and NO2 parameters before the pandemic in 2019 and after the pandemic in 2020. The results of this study are that the ambient air quality in urban areas Yogyakarta tends to experience a decline and the monitoring locations are located around industries and major road junctions. So, the mapping of ambient air quality itself can facilitate visualization research.
