Abstract

This paper studies the thermodynamic and magnetic properties of some diatomic molecules governed by Scarf and Morse non-central potentials under external magnetic and electric fields. The Schrodinger equation with Scarf and Morse non-central potentials is solved using Supersymmetric WKB quantization conditions to obtain the energy equation and wave function. The influence of the magnetic and electric fields on the energy eigenvalue was discussed. The results show that energy increases with the increasing magnetic field and decreases with the increasing electric field. Moreover, the thermodynamic and magnetic properties involving internal energy, free energy, specific heat capacity, entropy, magnetization, magnetic susceptibility, and persistent current were determined by calculating the partition function. The internal energy increases linearly with the increasing magnetic field for a given temperature. Meanwhile, the specific heat capacity decreases with the increasing magnetic field. We point out that the presence of magnetic and electric fields makes the system exhibit diamagnetic behavior.

Abstract

Radiotherapy is a non-surgery therapy that employs ionizing radiation like X-ray or even radiation to cure cancer as a curative activity. Radiation dose rate analysis is required for the person who worked on radiotherapy to strengthen safety precautions for radiation protection, notably in oncology radiation. The research attempted to disclose time trends and radiation dose rate exposure variations among personnel in radiotherapy installation. Radiation dose examination utilizing four-elements TLD received from 16 respondents grouped into six groups (radiation oncologist, medical physicist, radiotherapist, electromedicine, nurse, and sculptor). The number of occupancy exposures rose 55.5% from 2018 to 2022. The most significant annual radiation dose rate for 900 patient workloads attained by medical physicists was 0.996 mSv. In addition, electronics receive the lowest annual radiation dose at Unand Hospital. Annual effective dose exposure by radiation is still safe, below national or international regulations. However, a protective improvement process is vital to limit radiation interaction, particularly for medical physicists, who are the most vulnerable to radiation exposure.

Abstract

To achieve the high accomplishment of the supercapacitor, various electrolyte concentrations of Na2SO2 (0.5 M, 1 M, and 2 M) were added to the activated carbon (AC) electrode. The AC has a moderate surface area of 1,500 m2/g and a pore size of 1 nm (micropore scale). The AC electrode was deposited from the mixture of AC, carbon black, and polytetrafluoroethylene (PTFE) with a weight ratio of 8:1:1 using the doctor blade method. Cyclic Voltammetry (CV), Galvanostatic Charge Discharge (GCD), and Electrical Impedance Spectroscopy (EIS) were used to characterize the electrodes electrochemically. Based on CV, GCD, and EIS characterizations, the measured specific capacitance of 17.2 F/g and ESR of 4.4 W  exhibit the best performance due to their high ionic conductivity. We can conclude that 2 M Na2SO4 is a viable option for the ionic electrolyte of the microporous AC for the high performance of a supercapacitor.

Abstract

The Peter Half Slope method is valuable for estimating rock depths using total magnetic field anomaly data. It relies on graphical analysis and practical rules to gauge the depths of magnetic sources. This method finds significant utility in magnetic interpretation, measuring half the maximum slope distance on magnetic anomaly curves. The primary objective of this research is to determine anomaly depths within Medan City by applying the Peter Half Slope method. The study employs total magnetic field anomaly data from the Medan city area, a part of the Northern Sumatra Basin. The research methodology includes data preparation, reduction to the pole transformation, profile creation, maximum slope computation, half-slope determination, and identifying tangent points on both minimum and maximum curves. The difference between these tangent points is then calculated to derive the depth of the bedrock. Based on the depth calculations using criteria for very thin, intermediate thickness, and very thick bodies, depths of 401, 301, and 240 meters were obtained, resulting in an average depth of 314 meters. This method plays a pivotal role in characterizing subsurface rock structures and is essential for geophysical analysis and magnetic data interpretation.

Abstract

Globalization in the 21st Century era has the opportunity to cause a decline in character. The government tries to strengthen student character through the Pancasila Student Profile. STEM (Science, Technology, Engineering, and Mathematics) based learning can facilitate student’s character. This study aims to describe the implementation of physics learning with STEM and its effect on student learning outcomes and character development. The research design employed was quasi-experimental, and the research sampling technique used was purposive sampling to determine two classes of tenth-grade students of MA Al Anwar Sarang. The experimental class integrated the STEM approach into each learning activity, and the control class used the scientific approach. Student character development was measured using observation sheets, and student learning outcomes were assessed by analyzing pretest and post-test scores. The findings of this study highlight the potential of integrating the STEM approach with Problem-Based Learning (PBL) to effectively teach Newton's Laws and develop student character. The medium-level improvement in learning outcomes (gain n = 0.399) and the high percentage of Pancasila student profile character development (81.33%) indicate that STEM-based physics learning supports academic and character-building objectives. These results suggest that optimizing all aspects of STEM integration, from learning tools to activities, is essential for fostering student character development in alignment with the Pancasila student profile. Additionally, implementing STEM-based physics learning sustainably over an extended period is recommended to enhance long-term learning outcomes and character formation

Abstract

Indonesia has an abundant amount of industry. Production in large, medium, and small industries still uses gas and oil as fuel sources. The fuel sources used still come from non-renewable energy. There is a need for alternative use of renewable energy to reduce the use of non-renewable energy. One solution is the use of rice husk biomass as a fuel source. Rice husk is still often considered as waste despite its many utilizations. The utilization of rice husk waste must be improved to increase its beneficial value. Rice husk waste can be utilized as a fuel source in a husk furnace. A husk furnace is a cooking device in which the fuel (rice husk) is burned using direct combustion. This research aims to optimize the efficiency of the husk furnace by varying the size of the oxygen flow valve hole and the mass of water being heated. Tests were conducted on four variations of oxygen flow valve hole size, namely, 36x27 cm2, 36x34 cm2, 43x34 cm2, and 50x34 cm2, and two variations of water mass (6 and 18 kg). The research was conducted by heating water using the Water Boiling Test method with test parameters: heating time, fuel consumption rate, energy in, energy out, heat efficiency, heat transfer rate, and ash and charcoal yield. The significant efficiency value can be used as a reference for small-scale industrial rice husk furnaces. The most significant efficiency in the study was 54.99%, achieved by a 43x34 cm2 valve hole for heating 18 kg of water. Based on the most effective efficiency value gained, the expansion of the oxygen flow valve hole is sufficient to be used as a test parameter to test the optimization of small industrial-scale husk furnaces.

Abstract

This study investigates the impact of integrating peer instruction with PhET simulations and inquiry-based learning on physics education. Given the constraints of having only one class of 40 students, a one-group quantitative design was employed, complemented by a qualitative approach to create a mixed-method design. Quantitative analysis of pre-test and post-test results was performed using N-Gain, effect size, and paired samples t-test. Furthermore, qualitative analysis provided insights into students' learning experiences. The average N-Gain score initially showed a low increase (0.26), but excluding cases with negative gains revealed a moderate increase (0.38). The paired samples t-test confirmed a significant improvement in post-test scores compared to pre-test scores, with a large effect size (), demonstrating the effectiveness of the intervention. However, further analysis is needed to explore the distribution of student answers and underlying misconceptions. Some misconceptions were corrected, such as those related to distance, displacement, and velocity equations. However, kinematics graphs and vertical motion persisted. This finding underscores the urgency of refining teaching methods to address these persistent issues. The findings highlight the potential of this integrated approach to improve physics instruction and suggest that educators can use these insights to better support students' understanding of kinematics and graphical analysis.

Abstract

Grids are additional accessory in radiography that absorb scatter radiation hoping to reduce blurriness on the image.  Various type of grids is available in the market so the effect of those on image quality needs to be evaluated. The purpose of this study is to compare the quality of abdominal radiography images using three variations of grids (moving and stationary grid) and without using a grid in order to see the best type or grids to produce the greatest image quality. Abdominal radiography exposure factors were used to expose two phantoms. Pro-Fluo 150 phantom was used as the object to measure image quality such as Signal to Noise Ratio (SNR), Contrast to Noise Ratio (CNR), and spatial resolution. A survey of five radiologists was also performed to evaluate the contrast and the visibility of objects’ boundaries in Anthropomorphic phantom images. The result of this study showed that the usage of various grids gave different values of SNR, CNR, and spatial resolution. The exposure factor of 70-75 kV in each mAs have the highest SNR value (52,64-78,31). Images obtained without a grid and exposure factor of 80-85 kV in each mAs have the highest SNR value (160,65-800,48). Images obtained from using moving grid also have the highest CNR and spatial resolution, with score of 3.72 – 7.62 and 3.7 lp/mm. The results of radiologists’ survey showed that the average score for moving grid’s images was 29.8 of 30 with a percentage of 99.33%. Therefore, it that can concluded that images obtained with moving grid have the best quality that can provides contrast and shows the boundaries between organs clearly in abdominal radiography. Based on this research, it’s recommended to use moving grid for abdominal radiography examinations.

Abstract

Environmental Physics concepts are very likely to be explored to facilitate the cultivation of spiritual attitudes because they are closely related to phenomena in everyday life. Visual media can help visualize environmental phenomena so that they are easier to understand. This study aims to instill spiritual values through the concept of Environmental Physics as an alternative learning that focuses on the affective domain with the help of visual media. This study involved 15 science education postgraduate students. This research used a Pre-experimental design with a Shoot Case Study. The research design includes pre-experiment, experiment, and analysis of experimental data results. In the pre-experiment stage, the concept of environmental physics and spiritual attitudes were analyzed, learning tools were prepared, and questionnaire instruments for student perceptions related to the cultivation of spiritual values were prepared. At the experimental stage, the implementation of Environmental Physics learning integrated with spiritual values was carried out. In the post-experiment stage, data analysis and interpretation were carried out to answer research problems. Based on the results of data analysis, it is known that 92.15% of respondents strongly agree that learning environmental physics can instill awareness of the nature of God. Based on the results of the open-ended questionnaire, it is known that students can explain the content of spiritual values in various phenomena in the environment. In addition, students stated that visual media can facilitate the activity of instilling awareness that God is omnipotent over all the universe. Thus it can be concluded that environmental physics learning activities can instil spiritual attitudes through environmental physics content assisted by visual media. Science content, especially environmental physics, is very relevant in instilling spiritual values
