Abstract

A preliminary study highlights the persistent challenge of low problem-solving skills among 21st-century students. Therefore, this study examines the ECIRR learning model with a metacognitive approach to improve students' problem-solving skills in static fluid material. The method of this study is quasi-experimental with a one-group pretest-posttest design, enrolling 33 students from class XI at a public high school in Subang City. The Static Fluids Problem Solving Test (SPRING) instrument is used to collect data, which will then be analyzed using the stacking-racking technique. The results showed that ECIRR model learning with a metacognitive approach significantly improved students' problem-solving skills by 2.66 on the logit scale in the moderate category. The highest increase in problem-solving skills was on the plan a solution indicator, and the lowest was on the visualize the problem indicator. The decrease in the level of difficulty of the SPRING instrument indicates that learning has a positive impact. Thus, ECIRR model learning with a metacognitive approach can improve student problem-solving skills in a static fluid material. This study can be strengthened by using a control class to compare the results obtained in the control and experimental groups so that the effectiveness of the intervention can be determined objectively.

Abstract

This research investigates the impact of vibrations produced by blasting activities at the PT Semen Padang Mine, with a focus on vibration analysis and experimental characterization using the Micromate tool. The main objective of this research is to understand the vibrations resulting from blasting, analyze the impact of variations in PVS (Peak Vector Sum) values, and evaluate the effect on the surrounding environment, especially employee housing around the mining area. The research method used involves several important stages, first of which is the use of a Micromate tool to measure the vibrations produced during the blasting process. Micromate is a tool that can record and analyze vibrations with high accuracy, thus providing reliable data for further analysis. Apart from that, this research also uses power regression analysis to understand the relationship between PVS and Scaled Distance variables. This analysis is important to determine how variations in blasting distance and intensity affect the resulting PVS values. Then, a distance analysis was carried out to obtain a PVS value below 3 mm/s, which is considered a safe threshold to prevent structural damage to the building. The research results show several important findings. Even though the measured vibration values ​​are below the Threshold Values ​​set by environmental regulations, it is important to comply with all existing regulations to avoid long-term negative impacts. The power regression analysis carried out shows that there is a significant relationship between PVS and Scaled Distance, which means that the greater the distance between the blasting point and the measurement point, the smaller the PVS value detected. The validation results of this analysis are also in accordance with the empirical data collected during the research. In addition to these main findings, this research also provides several practical recommendations. One of them is setting the explosive charge to reduce the impact of the resulting ground vibrations. These arrangements include reducing the amount of explosive per blast or changing the blasting technique to reduce vibration intensity. In conclusion, this research provides an in-depth understanding of the factors that influence vibrations from blasting in a mining context. The results of this research have important implications for the development of more accurate and effective vibration measurement methods as well as for mitigating environmental impacts caused by blasting activities. This research not only provides new insights for the mining industry but also helps in formulating better policies to protect the environment and communities around mining areas. Thus, this research contributes to ongoing efforts to achieve a balance between industrial activities and environmental sustainability.

So that in the independent curriculum currently used in education, science literacy is one of the competencies that is very important and also needed by Pancasila students. The purpose of this study is to analyze the improvement of science literacy skills as a result of PjBL - STEM learning in class X in one of Bandung State High School on alternative energy material. The sampling consisted of 32 students and the sampling technique was taken using convenience sampling technique. Data collection used is by formative test description of science literacy skills. The test instruments used were 2 questions identifying scientific issues, 2 questions explaining scientific evidence, and 3 questions explaining scientific evidence.  The method used in this research is pre-experiment method using one group pre-test - post-test research design. The data that has been obtained is analyzed using the N-Gain value and effect size. The results showed that the value of students' science literacy skills increased with an average post-test score of 83.16 and the overall N-Gain value obtained was 0.57 and included in the moderate category, then the increase in students' science literacy in each indicator, namely in identifying problem issues, explaining scientific phenomena, and explaining scientific evidence has a moderate category. However, of the three indicators, the indicator of identifying scientific issues has the smallest N-Gain of 0.51. The calculation of the effect size value is carried out to determine how much influence learning using the PjBL-STEM model has in improving science literacy skills, so that in the research that has been done it is found that the effect size is 3.23 and is included in the "high" category. Thus, learning with the PjBL-STEM model has an effect in improving students' science literacy skills.

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.
