Resistivity method is a useful geophysical tool for investigating landslides. It can be used to estimate the subsurface structure of a landslide mass, the depth of the failure surface, and the lateral extent of a landslide. High resolution of resistivity data were obtained by applying Schlumberger configuration, while penetrating deepness was obtained by applying Vertical Electrical Sounding (VES) configuration. Interpretation of subsurface condition showed there was soil layer in survey area which was indicated as slip surface triggering the landslide.

Kabupaten Tapanuli Selatan secara geologi merupakan daerah vulkanik tua dan disertai dengan adanya sesar yang mengindikasikan adanya batuan teralterasi hidrotermal yang dapat menjadi salah satu indikator potensi keberadaan logam salah satunya emas. Secara geologi, emas merupakan mineral logam yang berkaitan erat dengan proses magmatik dan lingkungan pembentukannya berada di dalam batuan vulkanik. Kegiatan eksplorasi emas saat ini banyak dilakukan dengan metode pemetaan lapang, akan tetapi metode tersebut mempunyai kendala dimana memerlukan biaya, energi, dan waktu yang relatif tinggi. Oleh karena itu, diperlukan metode untuk memudahkan eksplorasi emas salah satunya dengan penginderaan jauh. Tujuan dari penelitian ini adalah melakukan pemetaan serta pengukuran luasan potensi mineralisasi emas di Kabupaten Tapanuli Selatan dengan cara mengetahui zona alterasi hidrotermal dengan menggunakan metode penisbahan saluran (band ratios) dan lineament (kelurusan) yang ada di lokasi penelitian. Hasil penelitian ini diperoleh potensi mineralisai emas tersebar di tujuh kecamatan, yakni di Kecamatan Batang Toru, Angkola Sangkunur, Sipirok, Angkola Timur, Aekbilah, Batang Angkola, dan Sayurmatinggi. Pengukuran luasan wilayah potensi mineralisasi emas dilakukan dengan membuat polygon area. Berdasarkan luasan total di setiap kecamatannya, diperoleh kesimpulan bahwa potensi mineralisasi emas di Kabupaten Tapanuli Selatan yang paling luas terdapat di Kecamatan Batang Toru, yang juga ditunjukkan dengan adanya aktivitas pertambangan emas resmi yang beroperasi di wilayah Batang Toru.

The magnetic method use to determine the subsurface structure based on variations in the magnetic field on the earth's surface. interpretation of subsurface structures based on magnetic data includes parameters of depth, size, and magnetic susceptibility that can be obtained through modelling. The modelling carried out in this study includes forward modelling and inversion modelling for various parameters and also inversion modeling on WDMAM magnetic data in the Ijen area. Forward modelling results show that the value of the total magnetic field will be increase if the depth distance of the source of the anomaly is smaller, the susceptibility is greater, and the size of the anomalous object is getting bigger. Meanwhile, the results of the inversion modeling of synthetic data show a fairly good match between the subsurface structure and the initial synthetic model. The results of inversion modeling on WDMAM data in the Ijen area with coordinate boundaries 8˚30'- 8˚39' S and 113˚30' - 114˚30' E show the subsurface structure in the form of prism blocks with susceptibility dominated by mimeral magnetite, ilmenite , and pyrotite rocks at varying depths.

The mathematical modelling of geological structures, i.e. magma intrusion or dyke, has been done,Â based on magnetic data with inversion techniques using MatLab. The magnetic equation is a non-linear equation, and completion is done using a linear approach to non-linear mathematical models of magnetic data using the Taylor expansion approach and Jacobi Matrix. The first step of this research is to make synthetic data forward modelling from the magnetic equation of magma intrusion or dyke cases without errors, and the next stepping then add errors to the data. The next step is to do an inversion to get the parameters sought, i.e. depth and angle of the magma intrusion, by giving initial guesses, and then re-correct iteratively until convergent results are obtained. Finally, parameters of slope dyke or thin magma intrusion and its depth can be determined. The results obtained indicate that this technique can be used to get physical parameters sought from magnetic data for simple geological cases, i.e. dyke and magma intrusion.

The Ngrowo-Ngasinan sub-watershed is a part of Brantas Watershed which has an important role for the aquatic ecosystems in the Brantas watershed. Land cover changes in this sub-watershed can be identified by utilizing remote sensing technology. The use of remote sensing technology by applying Landsat 8 image data can be done by classifying several classes of land cover in the study area. Land cover affected the flow rate of a watershed because of its association with several problems due to the conversion of land. Land cover which influences the watershed ecosystems is forest. In addition to land cover, regional rainfall also affects the flow rate (runoff) in the area

Faculty of Mathematics and Natural Sciences University of Jember located in Sumbersari District with lithological conditions in the form of volcanic rocks, lithosol soils, and regosol soils that are capable of absorbing water and potentially as aquifers. In point of fact, in the campus zona of the University of Jember including in the Faculty of Mathematics and Natural Sciences, there is always a shortage of freshwater for various academic and non-academic activities. Therefore, research needs to be conducted to assess the lithology of subsurface structures in the FMIPA zone so that the depth of groundwater layers and aquifer layers can be determined. The study was conducted using the Schlumberger array geoelectric resistivity method at 5 VES points. The results obtained in the form of resistivity log curves can be seen that at the five points VES has lithology in the form of clay, gravel, sandstone, and groundwater layer. Each VES point was identified the groundwater layer and some of them were identified as aquifers. The aquifer with the greatest thickness is found at point VES 2, which is to the west of the Baitul Ilmi Mosque, so it is recommended as the location of a new well.Keywords: lithology, aquifers, geoelectric resistivity method, groundwater.

Lack of clean water when entering the dry season is a problem that often occurs in the FMIPA University of Jember. The purpose of this research is to know and estimate the potential distribution of the aquifer in the research area. 3D modeling of resistivity data was carried out using Voxler software. The input of resistivity data from the measurement results in the research area that the inversion process had carried out. The modeling results obtained an aquifer potency of 207.862,21 m3 or 21.63% of the total volume on the model image's cross-sectional map, with an irregular distribution pattern. Finally, using this method, the modeling of the aquifer potential volume and distribution can be estimated, and can be used as consideration in the use of groundwater in the Faculty of Mathematics and Natural Sciences, University of Jember.
