Spatial Analysis of Flora Habitat Characteristics in East Kalimantan

Abstract

The research aims to produce a software for mapping and identifying habitat characteristics of flora in East Kalimantan based on remote sensing data. Identification of flora habitat characteristics in East Kalimantan will be very useful for conservation and restoration of flora habitat in the region. Data of flora species obtained from Herbarium Wanariset file which includes textual attribute, coordinates, and specimen photos. Dipterocarpus, Hopea, Macaranga, Shorea, and Vatica were used for the case study. Geological data and soil type were taken from the Indonesian Geospatial website. Slope and altitude were obtained from Digital Elevation Model (DEM) data. Rainfall data was downloaded from the Meteorological, Climatological, and Geophysical Agency (BMKG). Land Surface Temperature (LST), Normalized Difference Vegetation Index (NDVI), and Normalized Difference Built-Up Index (NDBI) were obtained from Landsat 8 image data after digital processing. The result of this research is a plugin function in QGIS that can be used for flora habitat identification. According to the research findings, only Shorea can grow in all environments. Dipterocarpus, Hopea, Macaranga, and Vatica have the specific characteristic. Dipterocarpus grows in Tanjunggredeb/ Napiku, Sinjin Formation, Telen Formation, and the Maau Formation. Macaranga and Hopea grow in the same place where aluvium deposits. Vatica only grows in the Maau Formation.
