We study single-brane 4 + n dimensions which is embedded in bulk 5 + n dimensions with scalar field and Gauss Bonnet terms in bulk. The brane field equation is obtained by performing a bulk field projection by using the Gauss-Codazzi equation. The Einstein brane field equation is formed into the standard Einstein field equation in the Theory of general relativity with additional terms Gauss Bonnet and extra terms. Furthermore cosmological application obtained by reviewing brane’s spacetime is homogeneous and isotropic. FRW metric is taken with two scale factors that are internal dimensions and external dimensions which have a relationship $b(t)=a(t)^\gamma$. A dynamic analysis is performed to determine the stability of this model by taking the case of the absence of extra terms. Finally, we get a stable solution for this model occurs when the extra dimension n=2.

Drought usually occurs, especially during the dry season in Bontoramba Sub districts, Jeneponto Regency, South Sulawesi. Therefore, it is necessary to study the potential of groundwater to meet the needs of clean water. The study was conducted to investigate the potential of groundwater both in position and depth based on the results of the interpretation of measurements. The research was done using Geo electrical Resistivity Schlumberger configuration method that gives good results vertically. The measurement points were selected through feasibility survey with a total of four measurement points. The length of the track used is a maximum of 300 meters. This research is an experimental research with a descriptive method. Data collected were analyzed and interpreted using Res2dinv software. Through the results of this interpretation, modeling of the distribution of the aquifer layer in the soil is then carried out which is projected as groundwater. The results showed that the ground water layer with resistivity value range 0 -100 Ωm. Line 1 and line 2 were on average at a depth of 10-30 m, while line 3 and line 4 at depth more than 30 m from the ground surface.
