Remote sensing often used in geothermal exploration because it was considered has many advantages. The aim of this research is to extract and analyze the lineament density in the Libungo geothermal area based on a Digital Elevation Model (DEM). Lineament is obtained from Digital Elevation Model (DEM) satellite image data downloaded from the Geospatial Information Agency (BIG) page. Digital Elevation Model (DEM) data processing uses Geomatica aplication to extract the lineament automatically. Extracted lineament is processed using Geographic Information System (GIS) aplication to produce a lineament density map and processed using Rockworks aplication to generate direction. Lineament density maps help identify permeability in the Libungo geothermal area. Based on the results of the extraction and lineament density analysis, it is interpreted that the Libungo geothermal area has a high-density value. High density values are associated with good permeability. A direction that affect lineaments in the Libungo geothermal area are northwest-southeast in the direction of Gorontalo's main geological structure. © 2022 Institute of Physics Publishing.
