Abstract Lore Lindu National Park or Taman Nasional Lore Lindu (TNLL) is a natural resource conservation area with various potentials of endemic flora and fauna diversity. This study aimed to estimate the value and spatial distribution of biophysical factors, energy flux, and evapotranspiration. This method used the Surface Energy Balance Algorithm for Land (SEBAL) model and performs the pessimistic, moderate, and optimistic scenarios. The number of measured parameters includes biophysical variables and energy flux variables. The results showed that the average value of evapotranspiration in forest areas was higher than open land or other land uses. The evapotranspiration values in the three images varied between 0.07 - 0.20 mm/hour. The dry month evapotranspiration in 2002 was 17%-32% higher than the dry months in 2013 and 2018. The build on the energy flux and evapotranspiration models results into the value of energy flux and evapotranspiration explanation in TNLL. The results can be controlled with efforts of increasing reforestation of forest land cover by 10%, controlling population growth by 1% per year, and increasing public awareness by 10%. This situation concludes that uncontrolled changes in forest land function and population growth in TNLL have an effect on changes in energy flux and evapotranspiration.
