Abstract:
ABSTRAKDesa Girimekar Kecamatan Cilengkrang kabupaten Bandung merupakan wilayah yang rawan longsor. Wilayah ini mempunyai ketinggian 800 mdpl ini merupakan morfologi perbukitan dengan kelerengan 10º hingga 40º. Longsor di daerah tersebut sering terjadi pada waktu musim hujan. Untuk mengetahui diketahui profil bawah permukaan yang menjadi penyebab terjadinya gerakan tanah di wilayah tersebut, dilakukan investigasi dengan menggunakan pengukuran dengan resistivitymeter. Data resistivitas diolah dengan menggunakan RES2DINV (2D Resistivity Inversion) dan dimodelkan dalam profil bawah permukaan yang menggambarkan 2D lapisan permukaan tanah atau batuan dengan nilai resistivitas yang berbeda. Pengukuran resistivity dilakukan pada 7 line pada lokasi yang mana sudah terjadi gerakan tanah. Dari hasil interpretasi data pemodelan maka diketahui pola perlapisan batuan di daerah telitian, dengan arah gerakan tanah menuju ke arah barat. Batas lapisan lapuk dengan bidang gelincir relatif dalam, yaitu sekitar 20 meter. Lapisan lapuk diinterpretasikan dengan batuan pasir tufaan dan endapan gunung api terlapukkan, dengan resistivitas 10 – 20 ohm meter. Sedangkan bidang gelincirnya merupakan lempungan dengan resistivitas 100 – 200 ohm meter. Untuk memastikan jenis batuan yang tergambar dalam profil resistivity tersebut perlu dilakukan data pemboran atau interpretasi dari data geologi yang tersingkap di sekitar lokasi telitian.

ABSTRAKSurvei magnetotellurik (MT) telah dilakukan di Gunung Merapi dengan menggunakan alat Phoenix Geophysics MTU5 pada Oktober 2016 dan Mei 2017. Pengukuran dilakukan dengan jarak tiap titik sekitar 1 km, durasi pengukuran untuk satu titik ±12 jam, dan lebar dipole 50 s/d 80 meter utara-selatan dan timur barat. Sebanyak 8 titik sounding digunakan untuk menyusun profil resistivitas 2-D di lereng utara dan selatan. Hasil menunjukkan bahwa resistivitas bawah permukaan Merapi terdiri dari 2 (dua) karakteristik nilai resistivitas yaitu zona resistivitas tinggi dengan nilai 183-50.000 ohm.m dan zona resistivitas rendah dengan nilai 20-175 ohm.m. Zona resistivitas tinggi dapat diinterpretasikan sebagai zona produk erupsi sebelumnya yaitu aliran lava dan material piroklastik lainnya. Sedangkan zona resistivitas rendah diinterpretasikan sebagai kantong magma terbagi menjadi dua bagian, bagian atas berada pada kedalaman 0 s/d 2.000 meter dengan diameter mencapai 1.000 meter yang mengindikasikan sebuah kantong magma dangkal, sedangkan bagian bawah terlihat menerus dari kedalaman 3.000 s/d 11.000 meter sebagai kenampakan dapur magma yang cukup besar dengan diameter rata-rata sekitar 2.000 meter yang diindikasikan sebagai kantong magma dalam. Hasil zonasi ini senada dengan posisi hiposenter dari kejadian gempa vulkanik periode tahun 2010. Selain itu, terlihat adanya struktur yang diindikasikan sebagai sesar yang memotong lintasan di sekitar puncak.Kata kunci: Gunung Merapi, kantong magma, magnetotellurik, resistivitasABSTRACTMagnetotelluric (MT) survey has been carried out on Phoenix Geophysics MTU-5 in October 2016 and May 2017. The measurement has been done with the distance between them approximately 1 km, its duration of each sounding was 12 hours, and dipole length varied from 50-80 meters on North-South and East-West direction. Here we use the result from 8 MT sounding to construct a 2-D electrical resistivity image of the northern and southern flank of Merapi. The results show that the subsurface resistivity in Merapi consists of two types of resistivity features, i.e. the high resistivity zone which having resistivity value 183-50.000 ohm.m and the low one which varied from 20-175 ohm.m. The high resistivity zone are the lava flow and another pyroclastic material, while the low resistivity zone interpreted as magma chamber divided into two parts: upper part, at a depth of 0-2,000 meters with 1,000 meters diameter which is indicated as a shallow magma chamber, lower part, continuously from the depth of 3,000-11,000 meters as the large magma chamber with an average diameter of about 2,000 meters. The zone can be correlated to the hypocenter position taken from the volcanic earthquake event of 2010 period. In addition, there is a structure which indicated as a fault that cuts the trajectory around the summit. Keywords: Merapi Volcano, magma chamber, magnetotelluric, resistivity

Abstract The effect of ultrasonic stress on the chemical properties of a silicon strain device has been studied. Possible chemical mechanisms which account for crystallographic orientation and resistivity are discussed in some detail. The sensitivity of the silicon strain gauge to ultrasonic stress shows a linear dependence. Radiation pressures from ultrasonic therapy sources have been measured with the silicon strain gauge transducer based on the calibration of the electrical output of the device against the acoustic power outputs of standard ultrasonic sources. An ultrasonic power meter has thus been developed for potential commercial use.

Abstract:
Chapter 3 reviews piezoresistive materials as smart sensors. Piezoresistivity is defined as a property of certain materials, such as metals and semiconductors, for which the materials electrical resistance changes purely due to mechanical pressure, stress, force, acceleration, strain, and stress. It is the physical property of certain materials which has been widely used to convert a mechanical signal into an electrical signal in smart sensors, accelerometers, tactile sensors, strain gauges, and flow meters and similar devices and microdevices. Metals do not exhibit piezoresistivity as they do not have a bandgap. The resistance of strained metal samples changes due to dimensional changes – this may not be considered as piezo-resistivity. The unit of piezoresistivity is ohm-meter or symbolically Ω–m. Metals and semiconducting materials exhibit such a property. The piezoresistive effect in semiconductors is generally several orders of magnitudes larger than the geometrical effect. This effect is present in semiconductors such as germanium, amorphous silicon, polycrystalline silicon, and silicon carbide, among others. Hence, semiconductor strain gauges with a very high coefficient of sensitivity can be designed, built and operated and utilized in various smart sensor applications and as microelectromechanical (MEMs) or nanoelectromechanical (NEMs) devices and systems.

Abstract:
Groundwater system is very vital to humanity and the ecosystem. Aquifers are determined based on the absence or presence of water table positioning, that is, confined, unconfined, leaky aquifers and fractured aquifers. The objective of this chapter is to discuss the characteristic and assessment of groundwater within the scope of vertical distribution of GW, types of the aquifer system, types of SW-GW interface, and SW-GW interaction at both local and regional scales. The properties of the aquifer depend on the physical characteristics of the materials (porosity, permeability, specific yield, specific storage, and hydraulic conductivities) which are determined by techniques like resistivity surveys and pumping tests followed by remote sensing and geographic information system for better information on the groundwater system. Furthermore, understanding the SW-GW interactions through available methods (seepage meter, heat tracer, and environmental tracer) is useful in watershed management, that is, risk management and assessment of the aquifer system.

Abstract:
Sustainable development means the utilization of resources at a rate less than the rate at which they are renewing. In India infrastructure industry is growing rapidly due to globalization and raising awareness. In the present study, challenges faced by countries like India are to sustain the existing expectations with limited resources available. Reinforced Concrete (RC) structure may suffer several types of defects that may jeopardize their service life. This chapter deals with condition assessment and repair of RCC (G+3) building situated at Northern part of the country. There are various techniques available for repair and rehabilitation of reinforced concrete structures. From a maintenance point of view, it is essential to take up the strength assessment of an existing structure. So, to find out the reason behind the deterioration of the concrete structures some of the NDT and partially destructive technique are used. The NDT tests conducted during this study are Rebound Hammer, Ultra-sonic Pulse Velocity, Concrete resistivity Meter, Ferro-scanning and Carbonation, etc. This chapter helps to explains, how identified the different parameters of distress building like strength, density, level of corrosion and amount of reinforcement. On basis of these results, apply a repair methodology to revert back the strength parameters of the buildings.

Abstract:
The research evaluates the aquifer and groundwater seepage all around the reservoir. Researchers employ imaging techniques based on the electrical resistivity of materials in two dimensions. Ten different profiles were obtained at the site of the study, each from a side perspective. The average length of the profiles is 90 meters, and their average depth is 25 meters. The RES2DINV tool was used to generate graphs of the resistance readings. Inside the reservoir, 2D electrical resistivity imaging (2D ERI) was acquired utilizing a Wenner array, and the data were analyzed utilizing a pseudo-section approach. The geology of the study area consists of red soil and weathered gneissic rock, both of which are appropriate for 2D electrical resistivity imaging due to their high contrast. As the resistivity data is interpreted along the profile, the model's resistivity pseudo section in the reservoir region becomes clear. The pseudo section indicates hard rock at a depth of 4.06 m to 5.96 m, where the resistivity ranges from 103 Ωm to 120 Ωm

Abstract:
The magnetic and electrical resistivity surveys have led to identifying the geological structure of Site 4 in Bębło, revealing varied limestone karren: karst grooves and clints, at a depth of one metre, under a shallow layer of humus and clayey loess. The bottom of those grooves may have been covered with flint concretions, and it is likely that flint was extracted exactly from there. The clarity of magnetic and geoelectrical anomalies in Bębło indicates that the test results reflect the true character of the mine. The absence of anomalies related to large and deep shafts seems to stem from the lack of those features in Bębło, not from their low susceptibility to geophysical testing. This substantiates the view that flint was extracted in Bębło solely by the method of open-pit mining. The area of intensive extraction may have coincided with the zones of lower resistivity, although this thesis must be verified by excavation. The examined part of the site was subjected to detailed surface survey. Mining items were detected throughout the surveyed area, while workshop items concentrated in the northern part of the site and were almost absent from the lower resistivity zones. This may confirm the opinion that the zones of homogeneously lower resistivity were produced by intensive mining that disturbed the near-surface layers of relatively high resistivity. It is worth noting that the lower resistivity zones do not show any anomalies produced by karst karren that are clearly traceable outside those sections. It is possible, therefore, that the karst features in those places were destroyed by Neolithic miners as well. The geophysical testing, carried out over five hectares, did not cover the entire site, as proven by the scatter pattern of the artefacts on the surface.

Abstract:
In order to determine the geothermal potential of the municipality of Baré-Bakem, located in both the sedimentary basin of Moungo and the volcanic region of Nkongsamba (Cameroon Volcanic Line), geophysical measurements using electrical resistivity tomography were conducted along a 1km profile between two opposing thermal sources spaced 20 meters apart. The profile was acquired in the SW-NE direction using a 945m-long array with 64 electrodes spaced at 15 meters intervals. The ZZRes2Dinv44 software was employed to generate investigative images. The obtained results along the profile reveal the presence of two geothermal zones of interest trapped within permeable sedimentary formations at depths ranging from approximately 20 to 110 meters and close to the surface. From a geothermometric perspective, chemical geothermometers such as silica and Na-K-Ca were calculated by collecting water samples from these thermal sources and analyzing the physicochemical parameters at the Laboratory of Geochemical Analysis of Waters (LAGE/IRGM) in Nkolbisson. The calculations indicate that the Baré-Bakem locality exhibits temperatures ranging from 51 to 90°C for near-surface anomalies and temperatures ranging from 283 to 300°C for deeper anomalies. These geothermal resources possess high energy potential suitable for electricity production.

Abstract:
Abstract Due to earth propagation losses the rectifier current pulses suffer considerable waveform deterioration as the penetration depth increases. Hence, cathodic protection benefits attributable to the use of a pulsed rectifier will not be attainable below a certain depth which is a function of the pulse characteristics and the soil resistivity. In this paper a hypothetical 3000 meter length well casing is modeled as a distributed lossy electrical transmission line. It is shown that below a depth of 300 to 500 meters, the higher frequency content of the pulse is severely attenuated. The cathodic protection process at these and increased depths, therefore, will not differ significantly from that obtained with a non-pulsed dc rectifier.

Abstract:
Abstract Sacrificial cathodic protection system was applied for protection of prestressed concrete cylinder pipe in the Great Man made River Project pipelines in Libya, where 100 mV Polarization\Decay criteria was used to evaluate the performance of the cathodic protection. Section of 2.29 km of protected pipeline that was existing between two sections of long non protected pipeline was selected for testing. All of the applicable tests were executed on the selected section before and after installation of sacrificial zinc anode system. The purpose of this study is to assess the reliability and efficiency of sacrificial CP system in the relatively high soil resistivity which has high chloride content and low moisture. The result of this study revealed that the 100 mV Polarization/Decay criterion was achieved in this section. The natural potential of the test section is ranged from +100 mV to -200 mV (CSE) before CP installation and the achieved instantaneous off potential was in the range of -100 to -300 mV respectively. The reliability of protected pipeline section that has achieved the 100 mV Polarization/Decay criteria is being assessed since 6 years by using of nondestructive testing inspection techniques of eddy current and acoustic monitoring to verify that this section is free of any failure resulted from embedded steel corrosion, and the result revealed that the 100 mV shift was efficient up to date.

Abstract:
Abstract In Canada and in the northern portions of the United States, soil resistivities increase rapidly by up to several orders of magnitude once water in the soil freezes in the winter. Frost-penetration can vary from centimeters up to a meter or more in depth. Although it is standard industry practice in the electrical industry to consider seasonal variations in soil resistivity when modeling grounding facilities for substations and generating stations, this is often not considered in AC interference studies related to pipelines. The effect on AC induction is expected to be minimal, as this is predominantly dependent on the deeper soil layers. However, frozen soil conditions can have a significant impact on the resistive coupling under a phase to ground powerline fault, and the effectiveness of the AC mitigation system. This paper involved a case study of a project involving AC interference on pipelines located in Canada. summer, and winter soil conditions were modeled to determine the effect on the subject pipeline under steady state and fault conditions. Allowable safe touch potentials were also calculated for these two scenarios, and used to assess the safety risks. A mitigation system was designed to ensure that the safety and integrity risks are mitigated to acceptable limits, for both seasonal conditions.

Abstract:
Abstract A maintenance program was designed to improve the cathodic protection level of two oil gathering pipelines of an oil production facility in Eastern Venezuela. The program was built upon the information obtained from a coating condition evaluation and the soil resistivity profile along the pipeline corridors. The external coating was inspected with the Direct Current Voltage Gradient technique, DCVG; the soil resistivity of the pipeline corridor was measured every 100 meters (328 ft.). All the geographical information was obtained with Differential Global Positioning System (DGPS). This allowed the pipeline operator to relocate all coating defects with a sub metric accuracy that considerably reduced the rehabilitation costs. The coating inspection covered a total distance of twelve thousand, nine hundred and thirty-six meters (12,936 meters). Two hundred and ninety two (292) defects were found, 54 defects belonged to Category 3 and will need immediate repair. The soil corrosiveness along the pipeline corridors was established by the resistivity gradient. Critical areas were established and exploratory digs were recommended to asses exposed metal condition.

Abstract:
Abstract The External Corrosion Control System of a 16 inch diameter (406 mm), 70 miles long (113 km.) pipeline, was evaluated using the Direct Current Voltage Gradient DCVG, Close Interval Potential Survey CIPS and Continuous Soil Resistivity Evaluation CSRE techniques. Sixteen thousand five hundred meters (16.500 meters. 10,23 miles) of the pipeline were evaluated using the three techniques simultaneously and the rest was inspected separately in previous years. The results from the survey were taken as parameters to classify all defects found on the protective coating. A Defect Severity Classification (DSC) was established and used as an input for a maintenance program for the rehabilitation of the pipeline integrity. The parameters taken to establish the DSC were: a) Instant Off Potential, b) %IR, c) Soil Resistivity, d) defect shape, e) Geographic location, f) Distance from drain point. A Maintenance Program for the Pipeline External Corrosion Control System was designed by implementing the Integral Evaluation of the Corrosion Control System for Buried Pipelines (IEECCSBP). The priority was to achieve pipeline integrity and then, gradually improve the protection level of the system. The implementation of IEECCSBP will help to reduce the frequency of Electromagnetic Metal Loss Inspections, which in the future will serve only as an audit of the External Corrosion Control System performance.

Abstract:
Abstract The design of mitigation to reduce AC interference levels in a pipeline is a relatively straightforward matter when the mitigation can be installed with the pipeline, at the bottom of the trench. On the other hand, retrofitting introduces design challenges, which are discussed in this paper. For one thing, the depth of burial of gradient control wires running parallel to the pipeline is often limited by practical considerations: as a result, the effectiveness of these wires is reduced by soil freezing in northern climes. A second problem is the frequent need to interrupt the gradient control wires at road crossings, water bodies, wetlands, and other such obstacles. The level of protection is obviously compromised to some degree at such locations. It is found that consideration of the exponentially decreasing nature of soil resistivity with depth, during frozen conditions, can result in a dramatically improved assessment of mitigation performance. It is also found that, depending upon the soil structure, gaps of tens of meters in otherwise continuous gradient control wires may yield acceptable performance.

Full text
Abstract:
Abstract Current drain to mud exposed (buried) structure such as piles is in reality dependent on the soil resistivity. The prevailing cathodic protection (CP) design standards vary in the recommended current drain to structures in mud. i.e. NACE SP01761 recommends a range of 1,5 to 5 Amps per pile, while DNV RP B 4012 recommends 20 mA/m2 for the total surface areas below mud line. A recent design case for an offshore jacket in fairly shallow waters, around 37 meters water depth with eight piles piled 135 m in the mud, where the intention was to cathodically protect the entire structure with remote sacrificial anode sleds show that the influence of current drain to mud exposed structures may be critical for dimensioning the CP system. For this actual case, where the CP requirements were to fulfill CP criteria as per COMPANY criteria close to DNV RP B 401, with additional 10% current density on the splash zone exposed surface areas, the current drain to the mud exposed sections of the piles represented around 30% of the total current demand for the jacket.

Abstract:
Abstract The Greater Gabbard Offshore Wind Farm is the world's largest offshore wind farm project (500MW) to move into the construction phase and will be built approximately 25 kilometers off the Suffolk coast of the United Kingdom (UK). The construction work started in summer 2009 and features 140 wind turbines each having a rated capacity of 3.6 MW. The turbines are mounted on steel monopiles and transition pieces in water depths between 24 and 34 meters. The selection of the optimal cathodic protection system was based on extensive computer modeling. The simulation campaign compared Impressed Current Cathodic Protection (ICCP), Sacrificial Anode Cathodic Protection (SACP) as well as combined approaches against operating parameters taking into account calcareous layer erosion, flow rate dependant polarisation behavior and layers with changing resistivity. In addition, the dissolution effects of the sacrificial anodes and remaining lifetime of the MMO anode pastilles have been simulated. This presentation details the results of the comparison study of the various cathodic protection systems as well as of the installed design.

Abstract:
The engineering behavior of frozen soils is critical to the serviceability of civil infrastructure in cold regions. Among various geophysical techniques, electrical resistivity imaging is a promising technique that is cost effective and provides spatially continuous subsurface information. In this study, under freeze–thaw conditions, we carry out lab–scale 1D electrical resistivity measurements on frost–susceptible soils with varying water content and bulk density properties. We use a portable electrical resistivity meter for temporal electrical resistivity measurements and thermocouples for temperature monitoring. Dynamic temperature-dependent soil properties, most notably unfrozen water content, exert significant influences on the observed electrical resistivity. Below 0 °C, soil resistivity increases with the decreasing temperature. We also observe a hysteresis effect on the evolution of electrical resistivity during the freeze–thaw cycle, which effect we characterize with a sigmoidal model. At the same temperature, electrical resistivity during freezing is consistently lower than that during thawing. We have implemented this sigmoidal model into a COMSOL finite element model at both laboratory and field scales which enables the simulation of soil electrical resistivity response under both short–term and long–term sub–freezing conditions. Atmospheric temperature variations induce soil temperature change, and thereby phase transition and electrical resistivity change, with the rate of change being a function of the depth of investigation and soil properties include initial water content and initial temperature. This study advances the fundamental understanding of the electrical behaviors of frozen soils and enhance the application of electrical geophysical investigations in cold regions.
