Abstract

This study investigates the impact of the Problem-Based Learning (PBL) model assisted by PhET simulations on students' understanding of physics concepts. Recognizing the persistent challenge students face in grasping abstract physics concepts, this research integrates innovative teaching methods to enhance conceptual comprehension. The study employs a quasi-experimental design with a non-equivalent control group format, involving eleventh-grade science students from SMAN 1 Bayan, North Lombok. The experimental group, taught using the PBL model enhanced with PhET simulations, demonstrated significant improvements in posttest scores compared to the control group, which followed traditional lecture-based instruction. Data analysis, including validity, reliability, discrimination power, and difficulty level tests, confirmed the robustness of the concept understanding instrument. ANOVA results indicated a substantial effect of the intervention, with the experimental group showing a higher mean score and lower variability in performance. The findings reveal that the PBL model, supported by interactive PhET simulations, effectively enhances students' conceptual understanding in physics. This study contributes to the broader discourse on educational innovations by providing empirical evidence of the benefits of combining PBL with technological tools in physics education. It underscores the need for student-centered learning approaches that foster critical thinking and active participation. Future research should explore the scalability of this method across diverse educational contexts and further refine the integration of digital simulations to cover a broader range of physics topics.

Abstract

Barium hexaferrite (BaFe12O19) is a material of significant interest due to its wide range of applications. In this study, we synthesized barium M-hexaferrites (BaFe12-2xCoxZnxO19) powders through the co-precipitation method, starting from BaCO3 and FeCl3.6H2O powders, with Co and Zn powders used as dopant materials. The variations in x values were set at 0, 0.2, 0.4, 0.6, 0.8, and 1. Our findings indicate that the co-precipitation method is highly effective for synthesizing barium M-hexaferrites (BaFe12-2xCoxZnxO19) nanomaterials, which contain more than 89% iron elements and have an average particle size of 50 nm. The Differential Thermal Analysis (DTA) and Thermogravimetric Analysis (TGA) reveal that phase transformations occur at temperatures of 285°C and in the range of 750-840°C. Further analysis using the Rietveld refinement method demonstrates that the barium M-hexaferrite phase begins to form at relatively low temperatures, with the most optimal yield observed at x = 0.4. At temperatures exceeding 740°C, there is a tendency to form a single-phase α-Fe2O3 (hematite). The introduction of Co and Zn as dopant ions results in only minor changes to the lattice parameters of the basic hexagonal crystal structure. This comprehensive study underscores the viability of the co-precipitation method for producing high-quality barium M-hexaferrites and provides valuable insights into the effects of Co and Zn doping on the structural and thermal properties of these materials.

Abstract

Education needs to enhance creative thinking skills, which are crucial in the era of the Fourth Industrial Revolution. However, traditional teacher-centered learning strategies have proven ineffective in fostering these skills, especially in challenging subjects like physics. The use of Project-Based Learning (PjBL) has been shown to improve students' creative thinking skills in physics education. This study aims to explore the impact of PjBL on students' creative thinking skills across various indicators in physics education by synthesizing findings from related research. The study employs a meta-analysis method, collecting empirical data using Google Scholar through Harzing’s Publish or Perish 8 and Mendeley reference management software. The search yielded 28 articles from 2014-2024, with 13 articles meeting the inclusion criteria and providing sufficient data to calculate effect size. The results show an effect size of 1.03 (high). The effect size interpretation indicates that PjBL has an 84% impact on students' creative thinking skills. Additionally, 19 research articles observed creative thinking indicators influenced by PjBL, with elaboration being the highest and flexibility the lowest. It is concluded that the application of the PjBL model significantly affects students' creative thinking skills in physics education.

Abstract

The primary objective of this study is to investigate the optical properties of polyvinyl alcohol (PVA) based polymer films, incorporating methylene blue (MB) dye and trichloroacetic acid (TCA), for their potential application in gamma radiation dosimetry. Specifically, this research aims to explore the effects of gamma radiation on the color change characteristics, optical absorption spectra, activation energy, and optical band gap energy of the PVA-MB-TCA polymer films. Additionally, the study seeks to assess the stability of these polymer films under varying doses of gamma radiation, ranging up to 14 kGy. The PVA-MB-TCA polymer films were prepared using a solvent-casting method. The polymer film samples were then exposed to gamma radiation from a 60Co source, with doses up to 14 kGy. The study observed significant color changes in the polymer films, transitioning from blue at 0 kGy to light blue-near transparent at 14 kGy. Spectrophotometric analysis identified three distinct wavelengths of maximum absorption at 360 nm, 440 nm, and 560 nm. As the radiation dose increased, absorption values decreased at 360 nm and 440 nm, while an opposite trend was noted at 560 nm. Furthermore, the activation energy of the polymer films was found to decrease with increasing radiation doses, indicating a reduction in the energy barriers for internal reactions. Similarly, the optical band gap energy also showed a decreasing trend with higher radiation doses across all types of transitions. These results demonstrate that the PVA-MB-TCA polymer films undergo significant optical and structural changes when exposed to gamma radiation, highlighting their potential utility as reliable high-dose radiation dosimeters. The stability of these films under radiation further supports their applicability in various fields requiring precise radiation dose monitoring, such as medical sterilization, food processing, and environmental safety.

Abstract

This study investigates the effectiveness of participatory learning combined with a critical problem-solving approach on junior high school students' science process skills in the context of simple machines. Conducted with 61 students from Central Lombok, the research involved an experimental group (31 students) and a control group (30 students). The experimental group received participatory learning treatment with a critical problem-solving approach, while the control group was taught using traditional expository methods. The intervention included three sessions focusing on pulleys, inclined planes, and levers, each lasting 90 minutes. Students' science process skills were assessed across five aspects: preparing practical tools, assembling practical tools, reading measurements, collaborating with peers, and conveying information. The results revealed that the experimental group significantly outperformed the control group in all aspects of science process skills, with higher mean scores and lower variability. The findings indicate that participatory learning with a critical problem-solving approach is more effective than traditional methods in enhancing students' science process skills. This study's outcomes suggest that integrating interactive and student-centered approaches in science education can foster critical thinking, collaboration, and practical application of scientific concepts. The research contributes to the existing literature by demonstrating the benefits of combining participatory learning and critical problem-solving in teaching complex topics like simple machines. Future research should explore the long-term effects of these approaches and their applicability across various educational contexts and subjects.
