Abstract

The compliance test of X-ray beam quality using HVL parameter on digital mammography was determined at a hospital in Makassar in 2019-2021. This measurement uses a ruler, X-ray multimeter, and aluminum filter. The exposure process is carried out at certain kVp and mAs conditions after placing the detector on the examination table. The HVL test to determine the X-ray beam quality is carried out by placing the detector 4 cm from the edge of the chest wall on the patient's table in an upright position facing the tube. The resulting HVL values ​​are 0.37, 0.37, and 0.38. This study resulted in a p-value of 0.000 (p < 0.05). Statistically, there is a significant difference in HVL values ​​in 2019-2021. The resulting HVL value is by the tolerance limit recommended by the IAEA, which is 0.31 ≤ HVL ≤ 0.58. These values ​​indicate that mammography works well, and it is safe for the patient.

Abstract

This study aims to determine the influence of the Inquiry-Based Learning model on students' scientific ability in Rotational Dynamics of a Rigid Bodies. This influence is seen from whether or not students can achieve the criteria of completeness by mastering three PISA (Program for International Student Assessment) indicators in 10 items on the test consisting of two questions to identify scientific problems, five question to explain phenomena scientifically, and three questions to interpret data and scientific evidence. The research method applied is the experimental method and uses the One Group Pretest-Posttest Design as a research design involving 4 classes, where 1 class acts as the experimental class and 3 classes as the replication class. Based on the statistical results of the t-test to test the research hypothesis, the t-count value for each sample class is greater than the t-table value. This shows that the use of the Inquiry-Based Learning learning model has an effect on students' scientific literacy abilities in the rotational dynamics of a rigid bodies

Abstract

Testing of optical fiber-based sensors using the imperfection method to detect alcohol contents. The sample results from mixing alcohol and distilled water to produce eight samples with an alcohol content level from 0% to 70%. The greater alcohol content causes the output power of the sensor to decrease due to the increase in the refractive index of alcohol content around the sensor. An increase in the refractive index of alcohol content causes power losses to increase, resulting in lost light intensity being transmitted in optical fiber-based sensors. Power losses are increasing to produce the best characteristics of the sensor. The best sensor is shown in the Gamma configuration at imperfection 3 with a sensitivity value of 0.346 µW/%. The imperfection method is suitable for determining the characteristics of optical fiber-based alcohol detection sensors because it has a high sensitivity.

Abstract

Garbage is something that humans throw away because it can no longer be used. An environment with a buildup of garbage can cause various problems such as hygiene, health, beauty, environmental pollution, and social issues. One of the problems regarding waste is located in Lopo Village-Gorontalo District. Garbage is thrown away and then burned, especially plastic waste. The combustion results can undoubtedly pollute the environment. This happens due to the need for more guidance and community empowerment in recycling waste into something that can be useful. One of the solutions for handling waste into something that can be useful is to convert plastic waste into fuel oil through the socialization of making a simple plastic pyrolysis machine. This socialization activity provides an understanding of waste and its impact on the environment, methods of waste management, and how to make a simple plastic pyrolysis machine. The participants were very enthusiastic about participating in this socialization because they learned how to process plastic waste into fuel and make simple plastic pyrolysis machines that can be products of high economic value

Abstract

This research was carried out using a literature review method to determine radioprotection cases and repeatability factors of dental images on dental X-rays. Determination of the repeatability factor for dental photographs using data over three months obtained at Rajawali Citra Hospital, RSUD Dr. Tjitrowardojo Purworejo, and RSUD Muntilan Magelang. Case A, case B, and case C produce high percentage values. This is because dental practitioners consider the provision of protection in reducing the scattered dose of dental X-rays for patients to be often overlooked. Determination of X-ray radiation exposure given by a radiographer does not have significant differences for each patient, such as thin, standard, and obese. Meanwhile, the data on the percentage value of repetition of dental images exceeds the Minimum Hospital Service Standard indicator limit by the Decree of the Minister of Health Number 129 of 2008 concerning the incidence of X-ray service failure, which has a photo failure standard of ≤ 2%. The highest position factor was obtained at Hospital-2 at 75%, and the lowest was obtained at Hospital-1 at 50%. Meanwhile, the highest exposure factor was obtained at Hospital-1 at 39% and the weakest at Hospital-2 at 25%. Position errors made by the radiographer cause position factors, and exposure errors are caused by exposure factors that are too high or low.

Abstract

The spectrum emitted by electromagnetic wave radiation has various frequencies, one of which is Extremely Low Frequency (ELF), and is often found in educational environments, originating from various electronic devices, high voltage electrical panels, and internet network supporting devices. Based on this description, it is necessary to measure ELF electromagnetic radiation in the Faculty of Mathematics and Natural Sciences environment at Universitas Negeri Gorontalo. This research was carried out by measuring magnetic field values (µT) at 42 location points using a Portable Electromagnetic Field Tester (EMF Tester). The research results show that all of these location points are within the safe threshold based on ICNIRP and WHO regulations, namely below 200 µT, with the highest ELF magnetic field value is 2.81 µT, and the lowest ELF magnetic field value is 0.003 µT. However, there are several studies showing that exposure to ELF electromagnetic field radiation can produce free radicals, causing cell damage. The results of this research can be used as a basis for making health policies for the Faculty of Mathematics and Natural Sciences academic community at Universitas Negeri Gorontalo.
