Abstract: This research was carried out by using the Wenner configuration of 2D Resistivity method. The object from this research was the archeology rock that came from the Deres Temple, one of the available cultural inheritances in the Jember Regency territory. This rock the possibility was under the surface and could be detected from the resistivity value. From results of the research, was expected still had parts of the Deres Temple that was buried under the surface of the land. With the depth of the revolving object between 0,50 m. up to 7,91 m.. The data that was received from the calculation showed the bricks resistivity value were identical to the brick resistivity value that referred to the rock table of Roy E, 1984.

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.

Abstract

Semburan lumpur di Kabupaten Sidoarjo keluar secara periodik, maka memerlukan ruang penampungan yang semakin luas. Bendungan yang dibuat tidak dapat menahan debit yang semakin banyak. Lumpur dialirkan dengan menggunakan saluran pipa menuju Kali Porong, yang bertujuan dibuang ke muara sungai. Permasalahan muncul diantaranya kondisi muara sungai yang semakin keruh oleh sisa-sisa material lumpur. Tujuan dari penelitian ini adalah mengetahui perubahan konsentrasi Total Suspended Solid (TSS), jarak sebaran TSS, dan tingkat kecerahan air di muara Kali Porong tahun 2014-2017. Nilai konsentrasi TSS menjadi parameter perubahan TSS. Hasil perubahan diklasifikasi berdasarkan kategori kelas TSS. Data hasil dicocokan dengan data buangan lumpur Sidoarjo oleh Pusat Penanggulangan Lumpur Sidoarjo (PPLS). Perubahan sebaran konsentrasi Total Suspended Solid (TSS) di muara Kali Porong dari tahun 2014-2017 memiliki nilai yang naik turun di tiap tahunnya. Tahun 2014 sebaran sebesar 509,056 Ha, tahun 2015 naik menjadi 1323,124 Ha. Sedangkan pada 2016 turun menjadi 714,076 Ha dan kembali naik pada 2017 menjadi 1350,210 Ha. Hal tersebut menyebabkan nilai sebaran konsentrasi TSS mengalami fluktuasi. Muara 3 menjadi muara yang selalu memiliki nilai jarak sebaran TSS tertinggi. Muara 3 tahun 2017 memiliki jarak terjauh dari penelitian yakni 4,295 km. Tingkat kecerahan air tahun 2014-2017 pada penelitian ini menghasilkan rentang nilai antara 4,561 m ? 15,432 m.

Abstract

The era of Majapahit kingdom is the most famous kingdom era in Indonesia. This is shown by many heritage sites in Indonesia, including some of the temples that have been found. generaly, the temples consists of red brick is visually the same as the other red brick. Contrain in identification of heritage site era is frequenly faced in escavation. In this research, red brick of Majapahit kingdom era will be characterise using resistivity value and compare to recent red brick. The red brick samples were taken from two temples in Jember, the Deres temple (the Beteng Site) and the temple in Wuluhan country. The research result that Majapahit kingdom era red brick has resistivity lower than recent red brick, 15.73 Ωm for the Beteng Site and 17,5 Ωm for the temple in Wuluhan country, whereas 22,56 Ωm for recent red brick. Therefore, red brick resistivity value can be use as characteristics to identify era of a heritage site, especially Majapahit kingdom era.

Abstract

Megalithic age artifacts are spreaded in the Jember region, one of them in the Kendal hamlet adjacent to the Duplang site. There are still many artifacts buried in this location that need to be explored using the geoelectric resistivity method of the Wenner configuration. Data acquisition was carried out on 3 lines with length of 40 m. Base on 2D resistivity distribution image for all three lines, it was known that the subsurface structures were dominated by clay with resistivity value of (1.54 – 89.4) Ωm. Resistivity anomaly with value (197-581) Ωm, which are suspected of being andesite stones forming the artifacts are at a depth (0.25 -3.19) m on the three lines. The presumption existence of the artifacts is reinforced by the presence of kenong rock and menhirs outcrops on line 2.

Abstract

The area around of Jember University has potential as a trading area because the majority of its citizens are immigrants. This potential is utilized by street food vendors located around the University of Jember. Most street vendors dispose of waste i.e used cooking oil directly around trading locations. One methode to determine waste seepage in the soil is to use the geoelectric method with crosshole dipole-dipole configuration. This research is a laboratory scale research. The sample of soil and waste of used cooking oil were taken from the location of street vendors around Jember University. Based on the research results, the soil resistivity value before being given the waste is 2.78 Ωm to 7.52 Ωm. While the value of soil resistivity after given the waste of used cooking oil ranged from 0.01 Ωm to 5.15 Ωm. Observations from the first day to the seventh day indicate that the movement of waste used cooking oil occurs vertically due to gravity and in all directions due to capillarity.

Abstract

Geoelectrical 3D resitivity measurement and soil’s index properties test has been conducted to determine soil type on settlement area Istana Tidar Regency, Jember. Resistivity measurement and soil sampling conducted at unoccupied area that have latitude (08°10’10,1” -08°10’11,9”) S and longitude (113°43’40,0”- 113°43’41,1”) E. Resistivity image of subsurface structure show that this settlement area was dominated by silty clay and sandysilt.To obtain more detailed information about the type of soil and its physical – mechanical properties, laboratory test done using soil’s index properties test. The result of soil’s index properties test show that this settlement area was dominated by silty clay have fine sand gradation and moderate plasticity.

Abstract

Tomography is a way to describe something non-destructively. Some types of Tomography are Electrical Resistance Tomography (ERT), Electrical Impedance Tomography (EIT), and Electrical Capacitance Tomography (ECT). This study aims to combine the ECT and ERT systems. The combination uses the ERT technique (Borehole method) and develops until it can be used like ECT. This research conducts three significant stages (design making, designed realization, and examination). The examination is carried out by simulation and experimental measurement. The simulation result is compared to the result of the experimental measurement. The result shows that both have the same patterns, but it has the amplitude of voltage difference pattern. It is because the resistivity result affects the measured voltage difference result. The higher the resistivity result of the medium, the smaller the measured voltage difference.Tomography is a way to describe something non-destructively.

Abstract

A research has been done using seismic refraction method to determine the depth of bedrock in the Village of Kemuning Lor, sub district of Arjasa, Jember. The Data acquisition was done by using 12 geophones and using weight drop vibrations sources. The distance between the vibration source and the first geophone is 10 meters away, while the distance among geophones is 2 meter away each. This Data acquisitions used two tracks (the first track was about 90 meters and the second track was about 40 meters). The first and second track were crossing each other, the first track lied from the main road to crevasse, while the second track lied in line with the crevasse. The result was that we were able to obtain three layers having the depth of 3,03-6,76 m; 4,37-9,93 m and 10,68-13,32 m, and having spreading speed 168,9-198,8 m; 425,1-511,7 m and 909,1-972,2 m. The obtained bedrock profile had declivity toward the crevasse and is assumed to have the potential of soil movement.
