Hotspot and rainfall analysis in Bombana District, Southeast Sulawesi Province

Abstract

Forest and land fires are starting to occur in eastern Indonesia, such as Southeast Sulawesi, frequently. Bombana District is one of the areas in Southeast Sulawesi Province with the highest total hotspots in the last decade. This study aimed to analyze the trend of hotspot distribution and its relationship with rainfall in the 2012 – 2021 period in Bombana District, Southeast Sulawesi Province. The sources used in this study were hotspot data from MODIS Terra/Aqua satellite imagery and rainfall data from the NASA Langley Research Center (LaRC) Power, which were analyzed using descriptive and regression analysis. The results showed that the total hotspots and rainfall in Bombana District between 2012 and 2021 fluctuated. The highest hotspot peak occurred in 2015, with 343 points. The hotspots and rainfall were significantly correlated, where rainfall greatly influenced the total of hotspots by 64% in 2012–2021.
