    A research has been conducted to analyze the susceptibility of seawater intrusion based on resistivity value in Banda Aceh city. The study aimed to see lithology of susceptibility of seawater intrusion areas by using 2D resistivity Wenner-Schlumberger’s configuration. This method is also used to interpret the subsurface layer structure of susceptibility of seawater intrusion in Banda Aceh city. In geomorphology and topography, the Banda Aceh plains extend to the southeast (around Krueng Aceh River) in Aceh Besar district (Western and eastern coastal areas) and Pidie district. Banda Aceh city has a slope of 0-8% and a height of 0-10 meter above sea level. The results in this study showed that the resistivity of susceptibility of seawater intrusion in the research area is below 1.45 Ωm with intrusion depth varies from 0 to 34,1 meter. Based on the analysis and interpretation of data, the subsurface structure of the region composed of sand, clayey sand, sandy clay and clay that spreads laterally. The deployment of seawater intrusion occurs at the northern part of Banda Aceh directly related to the coastal area.
