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.

Abstract

This study aims to visualize the temperature distribution on metal plates by solving elliptic differential equations using the help of the Microsoft Excel program. Many physics problems have limited analytic solutions so a numerical solution is needed. One of them is about the temperature distribution on a homogeneous metal plate in a steady-state conditionThe equation of heat flow in steady-state conditions is an elliptic partial differential equation (PDE). By solving this equation, we will have a numerical model of the plate that can be a mesh with a certain temperature point. Each point has been known to calculate the temperature value. The temperature value influenced. The Temperature value influenced borders on the plate and the presence of heat generation. The edge of the plate can be a constant temperature, a convection zone with the outside air, or an isolated edge. This model is then processed using Microsoft Excel with the iteration calculation until the temperature distribution value is obtained. The results obtained a graphical visualization of temperature distribution on the plate.

Abstract

The increasing need for electrical energy due to technological growth requires using sustainable alternative energy sources. One potential energy source is solar energy, which can be converted into electricity through a thermoelectric generator (TEG). This study aims to design an optimal TEG configuration in converting heat from zinc roofs into electricity and to analyze the effect of variations in the shape of zinc roofs on the electrical power generated. The method used is an experiment with variations in the type of zinc roof, e.g. plate, wave, and box, and the TEG circuit configuration, e.g series and parallel. Measurements were made on the temperature, voltage, current, and electrical power generated, both with and without supercapacitors as energy storage. The results showed that zinc plates with a parallel configuration produced the highest electrical power of 0.01372 W, compared to zinc boxes and wave zinc. The parallel configuration proved to be more efficient than the series configuration. In addition, using supercapacitors also increases the electrical power generated and allows for greater energy storage.
