Abstract

The mean ionization potential (I-value) is a primary determinant of the position of the heavy ion Bragg peak. To minimize their impact on beam range errors and quantify their uncertainties, the currently used I-values in Geant4 material database are revisited. The study aims at comparing set of I-values in different Geant4 versions and cross validation with PHITS Monte Carlo (MC) code. The Bragg curves of mono-energetic 290 MeV/u carbon ion beams in a Polymethyl Methacrylate (PMMA) phantom were simulated using Geant4 versions 10.6.2 and 11.2.1. Similar beam energies were replicated using the PHITS code. The Bragg curves showed good agreement between the two versions of Geant4 MC code for an I-value of 74 eV, corresponding to G4_PLEXIGLASS in the material database. When the I-value was lowered to 65 eV and 48 eV, the Bragg curves from Geant4 version 11.2.1 shifted to shallower depths. This research provides insights for evaluating the Geant4 physics model.

Abstract

This study investigates and compares the performance of a 10 Gbps optical communication link utilizing two prevalent single-mode fibers: G.652 and G.655. The analysis employs both theoretical calculations and Python-based simulations to assess the effectiveness of each fiber type in this high-speed transmission scenario. With the ever-growing demand for bandwidth in communication networks, 10 Gbps transmission systems are becoming increasingly commonplace. Single-mode fibers like G.652 and G.655 play a vital role in these systems, offering low signal attenuation for long-distance data transmission. However, each fiber type exhibits distinct dispersion characteristics, which can impact signal integrity over extended distances. This investigation adopts a two method for performance evaluation. Firstly, link power budget calculations are performed to determine the optical signal power before and after propagating through a 50-kilometer fiber span. The received power serves as the foundation for subsequent Q-factor and Bit Error Rate (BER) analysis. These calculations establish the theoretical limitations of the system based on well-defined formulas. Secondly, Python-based simulations are conducted to corroborate the theoretical findings and provide a more comprehensive performance assessment. This approach leverages the capabilities of two prominent Python packages: Opticomlib and OpticommPy. Opticomlib excels at analyzing the behavior of individual optical pulses within the system, enabling an understanding of the signal propagation. On the other hand, OpticommPy specializes in parameter sweep analysis, allowing for the investigation of how critical parameters like received power influence the Q-factor. By combining these functionalities, the simulations provide a detailed picture of the system's performance under various conditions. The calculated BER and Q-factor values for both G.652 and G.655 fiber links surpass the industry-accepted performance standards. These results demonstrate the effectiveness of using Python-based tools for comprehensive performance analysis of optical communication systems. However, it's important to note that slight discrepancies exist between the calculated and simulated results.

Abstract

Technological advancements in education have enabled the development of more interactive and easily accessible learning media for students. One such innovation is the use of an Android-based PowerPoint application, which can be utilized both offline and online to enhance students' interest and engagement in learning. This study aims to evaluate the feasibility of using an Android-based PowerPoint application, measure the responses of students at SMAN 1 Lenek to the application, and assess the differences in students' learning interest before and after using this learning media. The research employs a Research and Development (R&D) methodology, following six procedural stages: problem potential analysis, observation and assessment, design and development, product testing, revision, and implementation. Data were analyzed using the ideal standard deviation method and normalized gain. The ideal standard deviation method was employed to assess the validity of the instruments evaluated by media and material experts, as well as to measure the students' responses to the application. Normalized gain was used to determine the change in learning interest scores from questionnaires distributed before and after the learning process. The results of the study indicate that the developed Android-based PowerPoint application successfully increased the learning interest of 11th-grade science students at SMAN 1 Lenek, with a gain score of 0.225, categorized as low. The students' responses to the use of this application were very positive, with an overall average score of 4.4. This research successfully developed an Android-based PowerPoint application that can be accessed both offline and online, contributing positively to the improvement of learning quality.

Abstract

Radial Derivative Forward Modeling of Gravity Anomalies for Identification of Cylindrical Geological Features. The gravity method is a geophysical method with exploration costs that are quite cheap compared to other geophysical methods. This method is based on the density contrast of the target body with the surrounding. The cylindrical body is one of the targets among various other geological features. This research was conducted to test the ability of radial derivatives of gravity anomalies for targets in the form of cylindrical body. Radial derivatives consist of a first derivative and a second derivative. Forward modeling of cylindrical geological features is carried out analytically and with finite elements. Both calculations were carried out with a computer program based on Matlab. The results show that there is no difference in results either analytically or finite element wise. This method has been proven to be able to provide clear boundary positions on cylindrical geological features.

Abstract

This study evaluates the integration of online Pascal compilers in undergraduate physics education at the University of Mataram, focusing on its impact on students' programming skills. Over one semester, three classes (A, B, and C) of physics education students from the Department of Mathematics and Natural Sciences Education (PMIPA), Faculty of Teacher Training and Education (FKIP), University of Mataram, participated in lectures, discussions, and practical exercises using the GDB Online Pascal Compiler. Course content included Pascal fundamentals, arrays, matrices, and applications in physics, evaluated through assignments, mid-semester, and final exams. Quantitative analysis of student performance data revealed significant differences in mean scores and variability among the classes, with Class A achieving the highest average score and Class C exhibiting the greatest variability. Statistical tests confirmed that performance data for all classes deviated significantly from normal distribution, necessitating non-parametric tests. The Mann-Whitney U test indicated no statistically significant differences in median scores between class A vs. class B, class A vs. class C, and class B vs. class C, suggesting consistent performance outcomes across classes post-course. These findings underscore the potential of the online Pascal compiler in enhancing students' programming skills within the context of physics education.

Abstract

The guided inquiry learning model is a pedagogical approach that has demonstrated significant potential to enhance students' critical thinking abilities and their interest in learning. This study aims to examine the extent of improvement in students' critical thinking skills and learning interest through the application of practicum media integrated with the guided inquiry learning model. The research methodology employed in this study follows the Research and Development (R&D) framework, utilizing the 4D model (Define, Design, Develop, Disseminate) to systematically design and evaluate the instructional approach. The research was conducted over a period of two months at SMA Negeri 1 Sewon, involving 35 students from class X-9 as the sample. The students participated in guided inquiry-based learning activities that incorporated practicum media specifically designed for this study. To evaluate the outcomes, a descriptive statistical analysis was conducted using normalized gain scores to measure the improvement in students' critical thinking skills and interest in learning. The results of the study indicate a significant increase in both students' critical thinking abilities and their engagement with the learning material after the implementation of the guided inquiry learning model with practicum media. These findings suggest that the guided inquiry model not only facilitates the development of critical cognitive skills but also enhances student motivation and involvement in the learning process. Given these results, it is evident that the guided inquiry learning model, when supplemented with practicum media, provides a promising instructional strategy for improving both cognitive and affective domains of learning. Further research is recommended to explore the applicability of this model in different educational contexts and across various disciplines to confirm the generalizability of these findings.

Abstract

The great Aceh earthquake on December 26, 2004, had a magnitude of 9.2 Mw for 10 minutes with coordinates 3,316°N 95,854°E. had a tremendous impact on changes in geological conditions and disasters in Aceh and Asia, especially Southeast Asia and South Asia. Changes in geological conditions have resulted in Aceh and its surroundings becoming more prone to earthquakes, including volcanoes in North Sumatra. This research aims to determine the value of changes in coulomb stress that occur on Mount Sibualbuali and Lubukraya. This research uses the coulomb stress method presented in Coulomb 3.4 software. This research produces positive coulomb stress changes in 2021 which are marked by the red lobe, namely 0.197 bar on Mount Sibualbuali and 0.187 bar on Lubukraya. The highest increase in chwerees in coulomb stress was in 2015, namely 0.319 bar in Sibualbuali and 0.262 bar in Lubukraya. This research also resulted in the highest coulomb stress changes at a depth of 90-100 km so that it does not affect the volcanic activity of the two mountains.
