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.

Abstract

The use of handphone is increasing, making handphone users have to focus more on the side effects of using handphone on health. Handphone is included in the category of electromagnetic waves. Exposure to electromagnetic fields can affect human health, especially the hematological profile. This type of research is observational research with a descriptive approach. Hemoglobin, erythrocyte, leukocyte and thrombocyte levels were obtained from the results of blood checks in the laboratory. The results showed that exposure to handphone radiation caused a decrease in hemoglobin levels up to 11%, an increase in erythrocyte levels up to 13%, an increase in leukocyte levels up to 14%, and an increase in thrombocyte levels up to 35%.Handphone radiation triggersoxidative stress caused by formation of ROS (Reactive Oxygen Species).

Abstract

Fishermen use fishing aids called FADs to take advantage of Indonesia's marine potential. The problem fishermen face using FADs is the frequent loss of essential components in FADs, such as lights, batteries, and solar panels. Previously there was a security system that used SMS and GPS. However, there is no trigger, and still using SMS is a weakness of this existing system. This study aims to help solve this problem by developing a prototype that functions as a security system that no longer uses SMS and has a trigger. Rubot32 is the result of the design of this security system. It has an internal GPS to determine the device's position with sufficient accuracy. This ultrasonic sensor-based trigger will trigger a warning notification on the Telegram Bot and activates a high-voltage stinger and a functioning control system via Telegram Bot.

Abstract

E-books are essential in developing 4C skills and differentiated learning because they offer accessibility and flexibility that support students' diverse learning styles. In addition, they allow customization of teaching materials according to students' needs, which increases motivation and learning independence. This research aims to develop an e-book based on 4C skills through a differentiated approach to valid, practical science learning. This study falls within the development research category that uses the ADDIE model. With an average validation score of 3.73, this e-book falls into the “very valid” category. In practical terms, this media is easy for teachers and students to use, fits the learning plan, and shows a learning implementation rate of 90%. Student responses were very good, with an average of 89.79% for four evaluation indicators, showing great benefits and a high level of satisfaction in the learning process. Overall, the e-book based on 4C developed through a differentiated approach to science learning can be categorized as valid and practical because it can increase student involvement in learning. In addition, interactive features in e-books support communication and collaboration between students, allowing them to share ideas and opinions. E-books also enable teachers to adapt material to individual needs so each student can learn at the pace and style they desire.
