West Kalimantan, located along the equator, is a tropical area with high
surface temperatures. Decreasing forests or green spaces in this region could endanger
the creatures living there, due to rising surface temperatures. Hence, analyzing the
impact of Leaf Area Index changes on soil surface temperature is vital. This research
employed remote sensing technology via the Terra-MODIS satellite to analyze this
impact. The satellite imagery was used to determine Leaf Area Index (LAI) and Land
Surface Temperature (LST), using image data from 2001 and 2021 in West Kalimantan
Province. The research revealed that the region underwent changes, with wide pine
forests being replaced by savanna land. The surface temperature value with the largest
distribution area remained between 25ᵒC to 30ᵒC in both 2001 and 2021. LAI changes
affected LST by 46% to 47%, but substantial changes require a significant number of
years to observe.
