ANALISIS PENDUGAAN ADANYA SUMBER DAYA AIR DI DESA TANJUNG REJO, KECAMATAN WULUHAN, JEMBER REGENCY DENGAN METODE PENGUKURAN TAHANAN JENIS SCHLUMBERGER

Abstract

This research was conducted to assess the estimated presence of water resources in Tanjung Rejo Village, Wuluhan District, Jember, using a geoelectric resistivity method using the Schlumberger configuration. This approach was chosen because it provides more detailed information regarding subsurface resistivity variations, thus facilitating the determination of the presence, depth, and characteristics of aquifers. Field data collection took place on June 19, 2024, and yielded two groups of measurement data: shot 1 and shot 2. The data were then analyzed using statistical tests using SPSS software. A paired sample t-test yielded a significance value of 0.352 (>0.05), indicating no significant difference between shot 1 and shot 2. Furthermore, the Shapiro-Wilk normality test showed a sig. <0.05, indicating that the data were not normally distributed. Therefore, the analysis continued using the non-parametric Wilcoxon test. The Wilcoxon test results showed Asymp. The sig (2-tailed) value is 0.776 (>0.05), thus confirming that the two measurement data do not show significant differences. The consistency of the resistivity results indicates that the subsurface conditions at the research location are relatively uniform and do not show significant variations that could indicate changes in water resources. Overall, this research is the first step in the aquifer identification process in Tanjung Rejo Village. The findings can be used as a reference in developing further exploration strategies and more effective and sustainable water resource management for the local community.
