Abstract

Research on the analysis of the structure of the soil layer using the Vertical Schlumberger Geoelectric method in the Lecturer Housing Complex of Uncen Kali Acai, VIM Village, Abepura District, Jayapura City. This study aims to determine the soil layer, determine the location and depth of the soft soil layer, determine the soft and hard soil. Data retrieval using geoelectric resistivity method with vertical Schlumberger configuration. The instrument used for subsurface surveys is the HV 500 AK resistivity meter. Field measurements obtained electric current and voltage values and then calculated the apparent resistivity values obtained from analysis using IP2win software to see the distribution profile, depth, and thickness of the soil layer.After doing research in the field, it can be seen that the subsurface structure at the research site is dominated by soft clay material with a resistivity value of 0.24 -692.00 Ωm. . In addition, there is a layer of hard rock in the form of a mixture of limestone with a resistivity value of 1181.00 - 8319.00 Ωm.. And the types of subsurface rocks found at the research site are clay, sandstone and limestone.

Abstract

Research on identifying aquifer layers using the vertical Schlumberger Configuration Resistivity Geoelectric method was carried out in the Permata Hijau Housing Complex, Koya Barat Village, Muara Tami District, Jayapura City. This research aims to determine the resistivity, location and depth of the aquifer layer. The research methods used are field geophysical surveys and geophysical computing. The field geophysical survey method used is the geoelectric method. Field geophysical surveys, using the IREST300f resistivity meter, obtained other data on potential and electric current strength for field resistivity analysis. Computational geophysical methods provide the actual resistivity and vertical profile of soil layers. The number of vertical research points is 5 points. The research results show that there is an aquifer layer at each research point with variations in resistivity values, location and depth. The groundwater aquifer layers are vertical, namely at point 1 there are 2 free aquifer layers with resistivities of 3.34 Ωm and 1.65 Ωm. At point 2 there are 4 layers of unconfined aquifer with resistivities of 9.31 Ωm, 7.13 Ωm, 3.30 Ωm and 6.12 Ωm. At point 3 there are 3 layers of unconfined aquifer with resistivities of 5.61 Ωm, 3.00 Ωm and 1.61 Ωm. At point 4 there are 2 layers of unconfined aquifer with resistivities of 9.30 Ωm and 4.52 Ωm. At point 5 there are 3 unconfined aquifer layers with resistivities of 2.35 Ωm, 8.38 Ωm and 3.18 Ωm. The free aquifer layer is visible at point 1, found in layer 8 with a depth of 4.95-8.80 m and layer 10 with a depth of 19.20-24.00 m. The free aquifer layer is visible at point 2, found in layer 5 with a depth of 3.00-6.80 m and layer 7 with a depth of 16.10-20.00 m. layer 9 with a depth of 8.80-19.20 m and layer 11 6.12 Ωm with a depth of 53.00-76.00 m. The free aquifer layer is visible at point 3, found in Layer 5 with a depth of 3.40-6.00 m; layer 9 with a depth of 15.50-37.30 m; and layer 12 with a depth of 80.00-97.00. The free aquifer layer is visible at point 4, Layer 6 with a depth of 4.28-7.35 m. and Layer 10 with a depth of 50.00-57.40 m. The free aquifer layer is visible at point 5, Layer 4 with a depth of 5.31-5.65 m. Layer 8 has a depth of 15.50-39.00 m and layer 11 has a depth of 93.40-146.00 m.
