The study aimed to determine the structure of the subsurface layer through the propagation</span> <span lang="IN">velocity of secondary wave (Vs) in a layer of porous medium in estimating the potential for groundwater. </span><span lang="EN-US">This research s</span><span lang="IN">upported by resistivity </span><span lang="EN-US">data</span> <span lang="IN">​​</span><span lang="IN">and will be validated based on the depth of the well</span><span lang="EN-US">. </span><span lang="IN">MASW data was processed using WinMASW Professional 5.0 software to obtain a 1D profile of the Vs value, and Res2dinv software was used to obtain a 2D cross-section of the resistivity value. The results showed a decrease in the value of V</span><span lang="EN-US">s</span><span lang="IN"> in the porous medium layer from 133</span> <span lang="IN">to 358 m</span><span lang="EN-US">/</span><span lang="IN">s in the first path, and from 149 to 314 m/s for the second path. The decrease in the value of Vs is in the range of groundwater potential</span><span lang="EN-US"> which is close to the </span><span lang="IN">depth of the resident's well, with the type of porous medium layer being sands and intact clays. The subsurface profile from the Vs measurement shows </span><span lang="EN-US">a</span><span lang="IN"> good agreement with the resistivity value profile from the Geoelectric method. </span><span lang="EN-US">So,</span><span lang="IN"> secondary wave propagation </span><span lang="EN-US">can be </span><span lang="IN">used in determining groundwater potential for a depth of &lt; 10 </span><span lang="EN-US">m</span></span></div> ER -
