Abstract

Geoelectric is the most popular geophysical method for groundwater exploration. This method is based on measuring the electric current injected into the earth and measuring the potential generated at the surface. This research was carried out at Mount Tunak, on the island of Lombok, using the Wenner electrode configuration. The data is then processed using the Res2div software. The survey was conducted on two lines and obtained two parameters, namely the injection electric current measured at the current electrode and the potential generated at the surface measured through the potential electrode. The measurement results show the rock resistivity values between 0.053 to 194 Ohm-meters. The resistivity of the aquifer rock has a value of 1.67 to 4.25 Ohm-meter, which is a sandy claystone with an aquifer containing fresh water at the depth of about 20 meters below the surface. There is a presence of salty water below the fresh water with resistivity between 0.102-0.657 Ohm-m.

Abstract

Polymer gel dosimeters are fabricated from radiation sensitive chemicals which, upon irradiation, polymerize as a function of the absorbed radiation dose. These dosimeters, which uniquely record the radiation dose distribution in three-dimensions (3D), have specific advantages when compared to one-dimensional dosimeters, such as ion chambers, and two-dimensional dosimeters, such as film. This research aims to identify and analyze research trends of Polymer gel dosimeters. This research method is descriptive and analytical. The data used in this research was obtained from documents indexed by Google Scholar from 2016-2025 using Publish or Perish and Dimension.ai. Research procedures use PRISMA guidelines. The data identified and analyzed are the type of publication, publication source, and the title of research Polymer gel dosimeters that is widely cited. The data analysis method uses bibliometric analysis assisted by VOS viewer software. The results of the analysis show that research trend indexed by Google Scholar from 2016 to 2025 has experienced ups and down. There are many documents in the form of articles, chapters, proceeding, and edited books that discuss research about Polymer gel dosimeters. Key words that are often used in research about it are Magnetic Resonance Imaging, MRI, Monte carlo simulation, Characterization, Fricke gel, Polymerization, etc.

Abstract

The application of polymer dose gels is limited by the sensitivity of dose readout methods and dose gel properties. It is a challenge to find suitable dosimeters for registration of doses delivered to the target by orthovoltage therapy units. The application of metal-particle-enriched polymer composites for dose registration in X-ray therapy might be an elegant solution, especially if recent dose-reading technologies exploring advantages of different physical phenomena are involved. This research aims to identify and analyze research trends of Polymer thin film dosimeters. This research method is descriptive and analytical. The data used in this research was obtained from documents indexed by Google Scholar from 2016-2025 using Publish or Perish and Dimension.ai. Research procedures use PRISMA guidelines. The data identified and analyzed are the type of publication, publication source, and the title of research Polymer thin film dosimeters that is widely cited. The data analysis method uses bibliometric analysis assisted by VOS viewer software. The results of the analysis show that research trend indexed by Google Scholar from 2016 to 2025 has experienced ups and down. There are many documents in the form of articles, chapters, proceeding, monograph, preprint, and edited books that discuss research into the polymer thin film dosimetry. Key words that are often used in research about it are Gamma radiation dosimetry, Polyvinyl alcohol, PVA, TeO2, ZnO, Polymerization, etc.
