Urban areas with low vegetation trigger an increase in LST, while areas with dominant vegetation trigger a decrease in LST. Green space can produce shadows covering the earth’s surface to prevent heat radiation directly from the sun, while land expansion for residential, office, industrial, urban purposes, causing an increase in LST >30oC. The study is to analyse the distribution and relationship between NDBI, NDVI and LST in Bandar Lampung City using Landsat 5, Landsat 7 and Landsat 8 data from 1990 to 2020. There has been an increasing distribution of LST, which tends to the outskirts of the central city to the northwest, north and east from the centre of Bandar Lampung City. Although it is not significant to the maximum temperature, thus saw from the wide distribution of the LST region >30oC. Landcover changes based on NDVI and NDBI in 1990 tended to be low to moderate, while 2005 was moderate to strong and 2020 was strong. This relation indicates that the land cover change from vegetated land to built-up land affects the expansion of the LST area in 2020 compared to 1990 and 2005. The result concluded that the average LST trend from 1990 to 2020, increasing 4,5oC.
