Estimating Vegetation Temperature Condition and Its Impact on Drought for Natural Plantation Areas Using Multi-Band Sensor Remote Sensing Data

Drought is closely related to water reserves that are in the soil, both water reserves for land and for everyday human needs. In plantation, drought has a significant impact. Drought can be a barrier to plant production which will have an impact on local economic conditions. However, information about land drought is still lacking at this time. Even though the information is very much needed by various parties. This research uses remote sensing data on Landsat 8 imagery where this research aims to obtain a drought index value using the transformation of Land surface temperature (LST), NDWI and TVDI which will then be performed correlation regression equations and test the interpretation of accuracy of field data on the potential for a drought of plantation land in the research area. The results of data processing showed that the distribution of the most drought potential of plantation areas in Rempang Island was the potential for high drought with the total area of plantations having a high drought potential of 5737.073029Ha. The potential for moderate drought in the plantation area on Rempang Island has an area of 2851,479327 Ha. Low drought potential has the smallest area with a total area of the entire plantation area of 447.271236 Ha.
