Abstract

The utilization of radiation in the field of nuclear medicine uses several main tools, one of them is the gamma camera. In its use, the gamma camera must always be in prime condition in accordance with the regulation of the Badan Pengawas Tenaga Nuklir (BAPETEN) No. 17 of 2012. To ensure that the gamma camera is always in prime condition, it is necessary to carry out several QCs (Quality Control) within a certain period of time with reference to international standards and recommendations from manufacturers. QC results show the measured value still within the required range (acceptance criteria), so it can be said that the gamma camera is in prime condition and ready to be used. The Nuclear Medicine Installation of RSUD A. W Sjahranie Samarinda use Cobalt-57 flood source plates to measure extrinsic uniformity during daily QC. This study used data in the form of tables of extrinsic calibration measurements and verification measurements as well as graphs of Cobalt-57 activity against QC time with extrinsic calibration methods and verification measurements were shown in this study. The conclusion is the lower the activity, the longer the QC times. Besides, the QC times based on the extrinsic callibration and verification measurements are not much different.

Abstract

Indonesia is rich in various types of rocks, including igneous, sedimentary, and metamorphic rocks. Igneous and metamorphic rocks are commonly found in several regions of Indonesia, making the mineral resources of these rocks have significant potential in the country. X-ray diffraction (XRD) technique has advanced greatly in material characterization. The purpose of this research is to review various studies that discuss mineral characterization of rocks using XRD, as well as to examine different sample preparation methods, interpretation of XRD diffraction patterns, and how this technique is used to determine the mineral composition and crystallographic properties of materials in various types. The research methods used are highly varied for material processing, such as calcination, magnetic separation, slow evaporation, and grinding. The data variables obtained from this study include minerals, sample collection methods, structure, diffraction angles, composition, and their applications.

Abstract

In general, organic materials have been studied to have many benefits. One of the benefits of organic materials is that they can be used as the main ingredient for making sunscreen or sun protection, active ingredients in semiconductors, bioreductors, natural coloring materials and others. The Ultra Violet and Visible Light Spectrophotometry (UV-Vis) technique is a technique that has been widely used in research, especially in knowing the potential utilization of organic materials. The purpose of this research is to review various studies that discuss the characterization of organic materials using the Ultra Violet and Visible Light Spectrophotometry (UV-Vis) method to determine the benefits of organic materials by analyzing absorbance values and wavelengths. The method used was a literature study from October 30, 2024 to December 4, 2024. The variables studied in this research are absorbance properties, wavelength and the benefits of organic materials. The results showed that organic materials such as kalakai sprouts and roots have potential as sunscreen, coffee beans have the highest caffeine content, and breadfruit leaves and moringa leaves function as semiconductor active ingredients. Avocado peels produce high flavonoid levels, and coconut shells are effective as a base material for water filters. Water hyacinth and binahong leaves were used in bioreductors and optical property studies of C-dots, while turmeric, moss, pineapple shells and red cabbage were effective as natural colorants. Chili peppers, cacao pods, kalamansi citrus leaves, and soursop leaves were extracted to determine the levels of active compounds
