Geolectrical Equipment Research Activity in Laboratory of Exploration and Geothermal, at Geology Department ITB

This article is presented in the 5th ICONTES Kuala Lumpur, Malaysia. Author: Prihadi Sumintadireja. The Exploration Geology and Geothermal Laboratory (LEGG) was established in June 2017 as a research institution under the Faculty of Earth Science and Technology (FITB), Institut Teknologi of Bandung (ITB). As indicted by the three principle of higher education (Education, Research, and Community Services), the research lab has a goal to conduct researches on applied geosciences and modeling surface and subsurface geosciences data for exploration, geological hazard mitigation, and environmental geosciences and to publish the results both in national as well as international level. The lab specializes in creating a geological model from surface and subsurface data in order to solve real world problem.LEGG’s research activities that was done in between 2005 – 2017 are funded by ITB’s Research and Community Services Institute in addition to funding from petroleum and geothermal industry. The researches done in several stages that is listed below: 1.) Lab scale geo-electric measuring device prototype development, 2.) Field scale geo-electric measuring device development, 3.) Field scale measurement simulation, 4.) Environmental geoscience implementation and 5.) Petroleum industry implementation.This paper is meant to highlight the LEGG’s success story of more than 10 years of researching geoelectric acquisition and its implementaiton in the industry. The fruit of the research is LVG GLS, newly developed geoelectric acquisition instrument, that could record vast amount of higher quality data in shorter amount of time. Latest version of the device has 120 channels which means it has almost twice wider coverage and could be used to map three dimensional subsurface configuration quicker compared to any previous version.Keywords: Current and potential electrode, mise-a-la-masse, R&D, LEGG

ВИКОРИСТАННЯ ПРОГРАМ-ЕМУЛЯТОРІВ У НАВЧАННІ ФІЗИКИ МАЙБУТНІХ ТЕХНІКІВ ПРОГРАМІСТІВ

A modern gauge has been fused with digital and processor means of managing and processing information. Digital-to-analog (DACs) and analog-to-digital converters (ADCs) are widely used in various fields of modern science and technology. It is proposed to use the computer on the physics lessons and related subjects as the universal electric measuring device, which is based on using ADC and DAC audio adapter with an emphasis on the use of elements, means and principles of programming in its software. The study considers two aspects: methodology of teaching physics, gaining the professional competencies by engineer-programmers.
