Investigasi Sumber Mata Air dengan Metode Geolistrik GeoResist

metode geolistrik membantu menginvestigasi adanya sumber mata air, air permukaan ataupun akuifer yang ketiganya mempunyai ciri khas baik dalam karakter strukturnya atau lokasi keberadaanya.

Alat yang digunakan menggunakan alat single channel dengan dibuatkan switchbox sehingga bisa dilakukan pengukuran 2-D. Injeksi arus listriknya dilakukan secara manual tetapi akurasinya tidak jauh berbeda jika alatnya rutin di kalibrasi dengan alat-alat yang lebih bagus sensitifitasnya. Sebelum dilakukan pengukuran dilakukan terlebih dahulu survey tinjau untuk melihat struktur, pola sedimentasi dan topografinya sehingga kita bisa mengklasifikasi model air apa yang terkandung di bawah permukaan.

DI SEWAKAN DAN SPESIFIKASI SUPERSTING RESISTIVITY-IP METER R8 YANG DI SEWAKAN

Product Details

ItemDescription
Measurement ModesApparent resistivity, resistance, induced polarization (IP), SP, and battery voltage.
Measurement Range+/- 10Vp-p.
Measuring ResolutionMax 30 nV—depends on voltage level.
Screen Resolution4 digits in engineering notation.
Transmitter200W internal transmitter. 5kW, 10kW and 15kW external transmitters also available (see separate brochure).
Output Current1 – 2000 mA continuous, measured to high accuracy.
Output Voltage800 Vp-p—actual electrode voltage depends on transmitted current and ground resistivity.
Input ChannelsFive models available—8-, 6-, 4-, 2-, or 1-channel.
Input Gain RangingAutomatic—always uses full dynamic range of receiver.
Input Impedance>150 MOhm.
SP CompensationAutomatic cancellation of SP voltages during resistivity measurement. Constant and linearly varying SP cancels completely (V/I and IP measurements).
Type Of IP MeasurementTime domain chargeability (M). Six time slots measured and stored in memory.
IP Current TransmissionON+, OFF, ON-, OFF.
IP Cycle Times0.5, 1, 2, 4, and 8 s.
Measure CyclesRunning average of measurement displayed after each cycle. Automatic cycle stops when reading errors fall below user set limit or user set max cycles are done.
Resistivity Cycle TimesBasic measure time is 0.2, 0.4, 0.8, 1.2, 3.6, 7.2, or 14.4 s as selected by user via keyboard. Autoranging and commutation adds about 1.4 s.
Signal ProcessingContinuous averaging after each complete cycle. Noise errors calculated and displayed as percentage of reading. Reading displayed as resistance (dV/I) and apparent resistivity (ohmm or ohmft). Resistivity is calculated using user-entered electrode distances.
Noise SuppressionBetter than 100 dB at f >20 Hz.Better than 120 dB at power line frequencies (16 2/3, 20, 50, and 60 Hz) for measurement cycles of 1.2 s and above.
Total AccuracyBetter than 1% of reading in most cases (lab measurements). Field measurement accuracy depends on ground noise and resistivity.Instrument will calculate and display running estimate of measuring accuracy.
System CalibrationCalibration is done digitally by the microprocessor based on correction values stored in memory.
Supported ConfigurationsIn manual mode: Resistance, Schlumberger, Wenner, dipole-dipole, pole-dipole, and pole-pole.In automatic mode: Any configuration can be programmed via command file.
Operating SystemStored in reprogrammable flash memory. Updated versions can be downloaded from our website and stored in the flash memory.
Data StorageFull resolution reading average and error are stored along with user-entered coordinates and time of day for each measurement. Storage is effected automatically in a job-oriented file system.
Data DisplayApparent resistivity (ohmmeter), current intensity (mA), and measured voltage (mV) are displayed and stored in memory for each measurement.Data can also be displayed on an Android device in real time as bright color pseudosections, IP curves, transmitter/receiver plot, contact resistance measurements, and more.
Memory CapacityVirtually unlimited data storage in real time on controlling Android device.The internal SuperSting memory can store more than 79,000 measurements (resistivity mode) and more than 26,000 measurements in combined resistivity/IP mode.
Data TransmissionData can be instantaneously transferred from the Android device by email or by file transfer from the Android device USB port. RS-232C channel available to dump data from instrument to a Windows-type computer on user command.
Automatic Multi-ElectrodesThe SuperSting is designed to run dipole-dipole, pole-dipole, pole-pole, gradient, Wenner, and Schlumberger surveys including roll-along surveys completely automatic with the patented Dual Mode Automatic Multi-Electrode system (U.S. Patent 6,404,203) or a passive electrode cable system. The SuperSting can run any other array by using user-programmed command files. These are ASCII files that can be created using a regular text editor. The command files are uploaded to the SuperSting RAM memory and can at any time be recalled and run as a survey.
User Controls20-key-tactile, weatherproof keyboard with numeric entry keys and function keys.On/Off switch.Measure button integrated within main keyboard.LCD night-light switch (push to illuminate).Keyboard and LCD are mirrored to an Android™ device using Wi-Fi® technology for easy remote control of the SuperSting.
DisplayGraphics LCD display (16 lines x 30 characters) with night-light.Android mobile phone screen (7”) or 10” Android tablet with bright color AMOLED display.
Power Supply, Field12V or 2x12V DC external power—connector on front panel.Optional AC/DC power supply and motor generator.
Power Supply, OfficeDC power supply.
Operating TimeDepends on survey conditions and size of battery used. Internal circuitry in auto-mode adjusts current to save energy.
Operating Temperature-20 to +50°C when controlled by your Android device (phone or tablet). The instrument LCD screen fades out at -5ºC, but the instrument continues to function normally by your Android phone, kept warm in your pocket
Weight10.9 kg (24 lbs.).
DimensionsWidth: 184 mm (7.25″).Length: 406 mm (16″).Height: 273 mm (10.75″).

IDENTIFIKASI KANDUNGAN LIMBAH DAN SEBARANYA DI AREA PABRIK ATAU KILANG DENGAN METODE RESISTIVITY

Gambar pertama merupakan hasil pengukuran geolistrik di area yang relatif tidak terkena limbah sedangkan gambar bawah merupakan hasil yang terkontaminasi dengan limbah kimia.

pengukuran geolistrik akan memperlihatkan adanya nilai yang sangat jauh dengan estimasi daerah tersebut merupakan daerah dengan porositas tinggi atau sedimen seperti pasir dan sedimen laut.

Eksplorasi Batuan Andesit Menggunakan Naniura

Eksplorasi batuan andesit, breksi dan batuan vulkanik lainya banyak dilakukan sekarang-sekarang karena kebutuhan akan batuan ini sangat tinggi terutama untuk kontruksi baik jalan ataupun kontruksi lainya. Eksplorasi batuan andesit dan breksi banyak menggunakan alat atau metode geofisika dengan pendekatan tidak langsung dengan memanfaatkan sumber arus listrik atau Resistiviy-IP atau banyak orang menyebut dengan metode Geolistrik.

Metode geolistrik sudah sangat dikenal oleh orang-orang yang bergerak dibidang pertambangan dan eksplorasi lainya karena simpel dan hasilnya mendekati model bawah permukaanya. Metode ini banyak dikembangkan oleh akademisi atau swasta dengan berbagai merk dan kelebihan masing-masing. Salah satu yang masih banyak digunakan adalah merk Naniura dengan ciri khasnya yaitu masih menggunakan injeksi arus manual.
