Andesite is an intermediate igneous rock (Winter, 2014) formed near the earth's surface generally as part of a volcano due to tectonic activity. The research method carried out was by deleniating the volcanic distribution of the central Sipiso-piso formation sourced from the Sidikalang regional geological map using the coordinate points resulting from the delenition of the regional geological map as a reference at the research location for collecting data at the research location. So you can find out the extent and distribution of volcanic rock characteristics at the research location. The research location has 4 characteristics of volcanic rocks and the distribution area of volcanic rocks on Mount Sipiso-Piso is ± 631,447 ha, which is the result of calculations from Arcgis 10.8 software.
