Abstract

On March 11, 2020, the World Health Organization (WHO) declared coronavirus disease 2019 (Covid-19) a global pandemic. The uncontrolled spread of Covid-19 has caused world governments to impose restrictions on activities in public spaces to reduce positive Covid-19 counts. Similarly, Yogyakarta City also implemented this policy, which caused a temporary drop in land surface temperature (LST) as a result of lessened human activity. Human activities have an impact on various problems, such as the amount of energy consumption, vehicle pollution, and land use changes. This study used Landsat 8 and Landsat 9, for which the recording time was adjusted to the policy of the Government of Yogyakarta Special Region. Normalized Difference Vegetation Index (NDVI) and Normalized Difference Built-up Index (NDBI) are variables used as proxies for vegetation and building density, respectively. The objectives of this study were (1) to analyze the spatial distribution of LST due to reduced human activity before, during, and in the transition period of the Covid-19 in Yogyakarta City; and (2) to analyze the variation of distance relationships from road networks, vegetation density, and building density to LST before, during, and in the transition period of the Covid-19 in Yogyakarta City. The results showed that Yogyakarta City dominated the temperature range of 29.1–33 ℃, which changed to 24.1–26 ℃ as an effect of reduced human activity during lockdown. In the meantime, the relationship between NDVI and road network variables is more significant than that between NDBI variables. However, the three variables do not have a very significant influence when viewed based on the coefficient of determination of multiple linear regression.
