Investigating the Impact of Movement Restriction on Land Surface Temperature (LST) in Three COVID-19 Epicenter Cities in Indonesia

To prevent the spread of the COVID-19 virus, the Indonesian government has established a social restriction policy that includes restrictions on transport modes. Transportation is one factor that affects the LST value due to the pollution it produces. This study aims to identify the impact of mobility restrictions on LST in the three epicenters of COVID-19 in Indonesia, namely, Jakarta, Surabaya, and Makassar, and at the same time, identify its impact on diseases other than COVID-19 that are sensitive to temperature changes, particularly dengue fever. This study uses a remote sensing approach to collect and process LST data based on MODIS satellite imagery. The results showed a decrease in LST before and during the pandemic in three cities, in which the LST observations are seen to be in the lowest value. The decrease in LST also tends to be followed by a decrease in cases of dengue fever in the three study locations.
