Abstract

Indonesia's geographical conditions which are at the confluence of three tectonic plates contribute to the availability of geothermal energy. The first step that can be taken in geothermal potential exploration activities is to study the characteristics of geothermal potential areas. In this case the study of the characteristics of geothermal potential will be carried out in the Ijen Mountains complex. This study aims to analyze the distribution of geothermal potential based on land surface temperature, and geothermal manifestations based on the association of land surface temperature and geomorphology. Remote sensing data used in the study were Landsat 8 images acquired in September 2013, 2015, and 2017. The results showed that geothermal potential areas were in the interior of the Ijen Mountains caldera with a temperature anomaly of 26-50 °C which was dominated by high greenish vegetation. While some geothermal manifestations that have been recorded are known to be associated with lineament that intersects with high land surface temperatures, so that the lineament that has the potential to be a fluid discharge pathway for geothermal manifestations is lineament that consistently intersects with high land surface temperatures in September 2013, 2015, and 2017 with the Southeast-Northwest and Southwest-Northeast orientations.

Abstract

Energi panas bumi merupakan energi sumber daya alam berupa air panas atau uap panas yang terbentuk melalui pemanasan di dalam bumi. Salah satu daerah yang memiliki potensi panas bumi adalah Blawan-Ijen. Metode yang sering digunakan untuk identifikasi panas bumi adalah metode gravitasi. Data yang digunakan pada penelitian ini adalah data gravitasi satelit yaitu BGI dan GGMplus. Data Bouguer BGI merupakan data anomali bouguer yang sudah siap diolah, sedangkan untuk data GGMplus masih merupakan data gravity disturbance. Data gravitasi GGMplus tergolong data gravitasi yang masih baru, sehingga diperlukan pembandingan dengan data gravitasi lainnya. Tujuan penelitian ini adalah mengetahui korelasi antara data gravitasi BGI dengan GGMplus. Proses korelasi dilakukan untuk mengetahui seberapa besar kemiripan antara data gravitasi GGMplus dengan BGI. Korelasi dilakukan dengan membuat digitasi kontur anomali gravitasi pada software Surfer dan menghitung nilai korelasi antar titik data gravitasi BGI dan GMplus. Hasil yang diperoleh menunjukkan bahwa ABL GGMplus dengan ABL BGI memiliki kemiripan dengan nilai korelasi sebesar 0,94. Kontur ABL GGMplus dan ABL BGI menunjukkan bahwa daerah pegunungan Ijen didominasi oleh nilai ABL rendah dengan rentang nilai 70 hingga 100 mGal. Pada kedua kontur ABL tersebut juga teramati kontras anomali gravitasi yang menunjukkan keberadaan patahan.

Abstract

Kecamatan Arjasa Kabupaten Jember merupakan salah satu daerah yang rawan mengalami bencana tanah longsor. Salah satu penyebab terjadinya longsor akibat dari kondisi batuan yang lemah sehingga mengakibatkan massa tanah diatasnya bergerak. Kondisi ini dapat diketahui dari nilai resistivitas yang dideteksi menggunakan metode geolistrik. Nilai resistivitas menggambarkan jenis tanah untuk setiap lapisan tanah. Tanah longsor selain dipengaruhi jenis tanah, juga dipengaruhi oleh sifat fisis tanah salah satunya yaitu permeabilitas tanah. Tujuan dari penelitian ini yaitu untuk mengetahui hubungan antara hasil metode geolistrik dan uji permeabilitas tanah. Data resistivitas awal diolah menggunakan software RES2DINV yang selanjutnya diolah dengan software Rockworks untuk mengetahui sebaran nilai resistivitas dalam bentuk 3D. Uji permeabilitas dilakukan untuk mengetahui kemampuan tanah dalam melewatkan air. Diketahui hasil dalam bentuk 3D nilai resistivitas berada pada rentang (8.29 – 149.83) Ωm dengan jenis tanah lempung lanauan dan tanah lanauan basah lembek serta tanah lanauan pasiran. Uji permeabilitas tanah menunjukkan bahwa di daerah penelitian memiliki kecepatan permeabilitas lambat hingga sedang cepat. Tanah lempung lanauan lebih lambat dalam meloloskan air daripada tanah lanauan pasiran.

Abstract

The simulation of the wave propagation of the radar in the sub-surface was very important to be understood before being carried out of field acquisition,to maximize the design of the acquisition and to optimized radar gram data’s.One of the approaches in the simulation of the data was to use propagationmodeling of the electromagnetic wave by using the Finite Difference TimeDomain solution (FDTD). Modeling of electromagnetic wave propagation in theGPR requires a solution of Maxwell’s equations or present a finite-differencetime-domain (FDTD) solution of Maxwell’s that permit accurate computation ofthe radiated field from a transmitting antenna. Propagating through the air-earthinterface, scattering by subsurface targets and reception of the scattered fieldsby receiving antenna. This technique is second-order accurate in time andfourth-order accurate in space. In this paper, I demonstrate the synthetic radargram by applying this technique to two-dimensional examples from a subsurfaceof stratified media.

Abstract

The gravity method is a method often used in geophysical exploration. According to recent technological developments, data acquisition has evolved by utilizing satellite data and modeling, one of which is GGMplus gravity data. In this study, GGMplus gravity data will be used to map the distribution of maar and cinder cones in the Gunung Lamongan Region. To obtain the optimal local anomaly results of gravity data, a combination of power spectrum analysis and upward continuation filtering methods is carried out.ABL data contours are sliced, gravity anomaly data from each slicing path is processed using FFT so that the wave number and power spectrum values are obtained as well as the relationship graph between the two.The power spectrum analysis method provides window width data that is used as information on determining the height of the upward continuation method.The ABL contour map in the Gunung Lamongan region shows a range of gravitational field values between -20 mGal to 50 mGal. High anomaly values indicate the existence of Mount Lamongan which is dominated by intrusive rocks. The subsurface structure of the Gunung Lamongan region is thought to consist of tuff, lava, volcanic breccia, and lava. The existence of maar and cinder cones in the Gunung Lamongan area can be mapped from the contours of the local anomaly. Local anomaly contours are obtained from ABL data by connecting the two methods of filtering i.e power spectrum analysis and upward continuation. There are 10 cinder cones and 8 maar visible on the local anomaly contour map.

Abstract

In Indonesia is the Iyang-Argopuro Volcano Complex. The Research uses remote sensing methods and gravity methods conducted to study thermal anomalies and subsurface structures using Data images of Landsat 8 satellite and a data gravity of GGMPlus satellite. Moreover, the study aims to estimate the number of hoisting manifestations of the earth's heat at the compound of the Iyang-Argopuro volcano. Landsat 8 satellite image data is a spectral band (band 1-9) and a thermal band (band 10 and 11). The data was done in radiometric corrections, radiance correction, and reflex corrections, and was thus obtained a value of ground surface temperature (LST). The data was done in radiometric corrections, radiance correction, and reflectance corrections, to get an LST value. Processing data gravity of GGMPlus satellites with a bouguer correction, terrain corrections up to get a Complete Bouguer Anomaly (ABL) value. Furthermore, the ABL value consisting of regional and local anomalies is separated using an upward continuation filter to obtain local anomaly values. The results obtained from this study are five points of geothermal manifestation locations in the Iyang-Argopuro Volcano Complex which are located in the northern, central, southern and eastern parts. Manifestations in the northern, central, and northeastern parts have ground surface temperatures of 24-31 ̊C. While manifestations in the central and eastern parts have a surface temperature of land 21-31 ̊C. The high ground temperature values at the five locations were associated with low gravity values ranging from -20 mGal to -10 mGal. The low gravity value is assumed to have a rock structure with a low-density value. Low-density rock structures have the possibility of an outflow zone causing the soil surface temperature to be relatively high.

Abstract

The mathematical modelling of geological structures, i.e. magma intrusion or dyke, has been done,  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.
