The Covid-19 pandemic has made one of the tourists in the East Lampung regency inactive, namely “Gua Pandan.” Due to its unique location geologically, efforts must be made to revive the area. One of the approaches is applying an indirect method, namely the geophysical method. One of them is the geoelectrical profiling method. Six lines are spread in the study area with a length of 70-105 m. The target is a cave filled with air because it is suitable as a tourist spot. Based on the measurement results, a very high resistivity value of more than 5,000 Ωm is suspected to be an air-filled cave. The cave area that is probably safe is about 120 m long with 1-3 m depth below the ground surface, 2-8 m width, and 2-6 m height. However, a safety assessment is necessary for feasibility so that the cave is worthy of being re-activated as a tourist spot.

“…When polarized in the opposite direction, there should be no conduction, but there is conduction. This will tell you that the junction structure of the diode is damaged [6]. In the test studies, the current and corresponding voltage values measured in the nano-ampere range were transferred to a computer via the I2C compatible serial interface.…”

The voltage values used in an IV measurement often depend on the specific electronic components being tested. For example, to test a solar cell, voltage values in the range of -3 V - 3 V are sufficient, while for an LED this value is in the range of 0 V - 12 V. However, sometimes applying a voltage can change the electronic properties of a system under test. For example, the voltage applied to a diode changes the capacitive values of the diode. Therefore, the parameters of the tested system should not change the current-voltage values of the testing system during the test. In this study, a software-controlled current-voltage device was designed and built to overcome this problem. We interpreted the accuracy of this system by measuring the turn-on voltage of an OLED device we produced in the laboratory.

The groundwater depends on when it is available, more in the rainy and less in the dry seasons. Fluctuation in water availability is a significant problem in activities continuously requiring large amounts of water, such as agriculture. Hence, it is necessary to increase the number of water resources to meet the community's needs. Therefore, the groundwater layer zone was estimated as an initial study at the dry farmland in Rejomulyo village, Jati Agung district, South Lampung, using a combined method between the 1D resistivity method of the Schlumberger array and the 2D form of the Wenner configuration. Each sounding point and the 2D line have a maximum stretch length of 300 m. The 1D outcome correlates to the 2D data processing result to produce a subsurface lithology model. As a result, the research area has three primary layers with three rock types. The first layer has a resistivity value of less than 20 Ωm and is identified as tuffaceous clay. Then the second layer with a resistivity range of 60–66 Ωm is tuffaceous sand, this rock which is referred to as the groundwater layer with a depth of 11-40 m. The last layer has a high resistivity value of 120–141 Ωm as tuff. Based on the results of 3D visualization, the groundwater layer in the study area spreads to the southeast with a confined aquifer type. This targeted rock layer can be utilized for groundwater production.
