Abstract

The rapid development of digital technology has opened new opportunities for integrating virtual experiments into physics education, particularly during periods when face-to-face learning is limited. This study aimed to analyze projectile motion by determining the maximum height (Hmax) of a ball through a virtual experiment using Tracker software. The research employed a quantitative descriptive experimental design in which video analysis was conducted to capture and model parabolic trajectories, followed by calculations of maximum height and relative error. Data were obtained through repeated trials, and the results demonstrated that the measured trajectories were consistent with the theoretical model of parabolic motion. The experimental findings showed that the calculated Hmax values closely approximated theoretical predictions, with small relative errors confirming the reliability of the software in simulating motion. These results indicate that Tracker software is not only a powerful visualization tool but also a valid quantitative platform that supports students in linking theory with practice, analyzing real-world phenomena, and understanding the importance of error analysis in physics. The implication of this study is that integrating Tracker into physics instruction can enhance students’ conceptual understanding, scientific literacy, and analytical skills, while providing a cost-effective alternative to conventional laboratories in both face-to-face and remote learning contexts.

Abstract

The Covid-19 pandemic has transformed higher education by accelerating the adoption of digital learning resources, with e-books emerging as one of the primary media to support online learning. However, despite their accessibility and flexibility, questions remain about their actual effectiveness in facilitating student learning, particularly in physics education where abstract concepts require diverse instructional strategies. This study employed a quantitative descriptive design using a structured questionnaire distributed via Google Forms to 28 undergraduate students in the Physics Education program at Universitas Indraprasta PGRI, Jakarta. The instrument consisted of multiple-choice and Likert-scale items to capture patterns of e-book use, perceived effectiveness, and student satisfaction. The findings showed that 92.9% of respondents acknowledged e-books as beneficial for their learning, and 85.7% reported that they improved their understanding of physics content. Nevertheless, only 28.6% frequently used e-books, and the average satisfaction score was moderate at 3.39, indicating that while students recognize the instructional value of e-books, their actual adoption remains limited due to factors such as monotonous presentation and lack of interactivity. These results are consistent with prior studies on digital reading preferences, but the study contributes novel insights by highlighting the paradox between high perceived usefulness and low frequency of e-book use in the context of physics education during pandemic-driven online learning. The implication of this research is that e-books should be redesigned with multimedia features, interactive problem-solving tasks, and integration into blended instructional approaches to enhance their pedagogical impact and ensure sustained student engagement in post-pandemic learning environments.

Abstract

This study investigates the effectiveness of flipbook-based e-modules in improving high school students' conceptual understanding of physics. Flipbook-based e-modules integrate multimedia elements such as videos, animations, and interactive quizzes, offering a dynamic and engaging learning experience. A meta-analysis of 10 relevant studies was conducted to evaluate the impact of these e-modules on student engagement, academic performance, and conceptual understanding. The results show that flipbook-based e-modules significantly enhance students' understanding of complex physics concepts, with improvements in academic performance and increased student engagement. However, challenges related to technical issues and preparation time were also identified, suggesting the need for further development in the technical infrastructure and teacher training. This study contributes to the growing body of literature on multimedia learning tools, offering insights for educators seeking to incorporate interactive digital resources into their teaching practices.

Abstract

This study reviews how e-learning media can be designed to support junior-high students’ understanding of straight motion (kinematics) in science classes. Using a narrative literature review, we searched scholarly sources on lower-secondary physics and online/blended instruction, emphasizing 2018–2022 publications and Indonesian implementations during and after the COVID-19 shift; inclusion required relevance to straight motion (e.g., motion graphs, constant velocity/acceleration), explicit use of e-learning platforms or digital resources (e.g., Zoom/Meet, Google Classroom/WhatsApp, Quizizz/Kahoot!, simulations/visualizations), and reportable classroom practices or outcomes. Evidence was extracted on context, platforms, activity structures, representational foci, and reported affordances/constraints, then synthesized thematically. The findings indicate that sequences are most effective when pedagogy not platform novelty drives design: brief multimodal explanations interleaved with questioning and peer talk, layered visuals that explicitly link narratives of motion to position–time, velocity–time, and acceleration–time graphs, and frequent low-stakes retrieval to surface misconceptions about slopes, areas, units, and terminology. Videoconferencing is beneficial when used for short, dialogic segments rather than prolonged lectures; game-based quizzing improves engagement and provides rapid diagnostic feedback; and visualizations/simulations help reduce representational load. Effectiveness is conditional on access and structure, with bandwidth/device constraints and limited oversight of hands-on work as recurrent barriers. This review contributes topic-specific, context-aware design heuristics for straight motion at the junior-high level. Implications include adopting lightweight, bandwidth-resilient “explain–check–discuss” playbooks; curating shared banks of visuals and formative items focused on motion-graph interpretation; providing teacher professional development on discourse moves that elevate student voice; and prioritizing equity-minded participation monitoring to guide iterative improvement.

Abstract

The mastery of physics concepts among junior high school students remains a challenge, particularly in topics that involve abstract phenomena such as light and optical instruments. This study aimed to improve students’ conceptual understanding and learning motivation through the integration of the discussion method and virtual laboratory media. A classroom action research (CAR) design was employed in two cycles, each consisting of planning, implementation, observation, and reflection stages, conducted with 35 eighth-grade students at SMP Al-Kindi Cipayung. Data were collected using tests, questionnaires, and observations, while results were analyzed descriptively through mean scores and mastery percentages. The findings showed a steady increase in student learning outcomes, with mastery achievement improving from 31.42% in the pre-cycle to 60% in the first cycle and 91.42% in the second cycle. Students also reported positive responses to the use of virtual laboratories, noting their role in clarifying complex concepts, enhancing interaction, and creating a more engaging learning environment. The novelty of this study lies in combining collaborative discussion with digital simulation, offering an alternative pedagogical strategy to compensate for limited physical laboratory resources. These results imply that integrating traditional discussion with virtual laboratories can serve as an effective approach to foster conceptual understanding, critical thinking, and motivation in physics learning, and that broader implementation across schools could enhance the quality of science education in resource-constrained settings.

Abstract

The declining interest of students in physics education has become a major concern in many universities, as it influences persistence, motivation, and the future supply of qualified physics educators. This study aimed to investigate the reasons behind students’ decisions to enter and remain in the Physics Education Program at Universitas Indraprasta PGRI and to explore the extent of their interest in the field. Using a mixed-method descriptive approach, data were collected through questionnaires distributed via Google Forms to 18 participants out of a population of 30 students and analyzed qualitatively and quantitatively. The results revealed that 38% of students expressed strong interest in physics education, 42% reported limited interest, and 20% remained neutral, while factors such as family encouragement, peer influence, and lecturer support emerged as key determinants sustaining students’ persistence despite limited intrinsic motivation. The discussion indicates that student engagement in physics education is not merely shaped by individual passion for the discipline but is strongly reinforced by social and contextual factors that enable students to adapt and continue their studies. The implication of this research is that higher education institutions should develop strategic interventions, such as peer mentoring, family-inclusive support systems, and contextualized learning approaches, to strengthen student motivation and reduce attrition in physics education programs.

Abstract

Education in the 21st century requires innovative approaches that integrate technology and local wisdom to strengthen students’ science process skills (SPS). This study aims to develop, validate, and evaluate the effectiveness of ethno-vlog and virtual reality (VR) media based on the cultural context of Oyol tea in enhancing junior high school students’ SPS on ecology and biodiversity topics. Employing a research and development design with the 4D model (Define, Design, Develop, Disseminate), this study involved small-scale (n = 15) and large-scale (n = 32) trials with grade VII and VIII students at a junior high school in Indonesia. Data were collected through expert validation, student response questionnaires, observation sheets, and pre-post assessments of SPS. The results indicated that both media met the “very feasible” criteria from expert validators (average ≥ 87.5%) and received highly positive responses from students. Statistical analysis using N-gain (0.76, high category) and the Mann–Whitney test (p < 0.05) confirmed a significant improvement in students’ SPS, particularly in observation, prediction, inference, classification, measurement, and communication skills. These findings demonstrate that the integration of ethnoscience-based vlog and VR provides a meaningful, interactive, and culturally relevant learning experience. The study contributes to digital pedagogy by bridging local knowledge and advanced technologies, offering a scalable model for science education in developing countries. Future research may extend this approach to other cultural contexts and subject areas to strengthen broader applicability.

Abstract

The low level of Indonesian students’ science literacy as reflected in the PISA 2022 results highlights the need for innovative, contextualized learning media that can bridge scientific concepts with real-life and cultural experiences. This study aimed to develop and evaluate a Liveworksheet-integrated E-LKPD enriched with an ethno-vlog of Bukit Manengteung on ecology and ecosystem material to enhance students’ science literacy. Employing a research and development design with the 4D model (define, design, develop, and disseminate), the product was validated by experts, tested for readability, and implemented with seventh-grade students at SMP Negeri 2 Ciledug during the 2024/2025 academic year. Validation results indicated high feasibility with Aiken’s V values above 0.87, while student responses confirmed that the media was engaging, clear, and easy to use. Effectiveness tests showed a significant improvement in students’ science literacy, with pretest and posttest scores increasing from an average of 45.69 to 81.72 and an N-Gain of 0.68, categorized as medium to high. Improvements were observed across all science literacy dimensions, particularly in scientific attitudes, and the integration of ethno-vlog content enabled students to contextualize ecology concepts within their local cultural environment. These findings confirm that the developed media is valid, practical, and effective, with implications that integrating ethnoscience-based digital media into science instruction can enhance students’ scientific competencies while simultaneously preserving and strengthening cultural identity.

Abstract

This study evaluates the potential of soybean pulp oil as a natural preservative for Wagyu beef, specifically examining its effects on moisture retention, protein, and fat content. A Completely Randomized Design (CRD) was employed with four treatment groups (1%, 3%, 5%, and 7% soybean pulp oil) and five replications per treatment. The beef samples were stored for 12 hours at room temperature (30°C), and their chemical composition was analyzed for moisture, protein, and fat content. The results demonstrated a significant improvement in moisture retention in the 1% and 3% soybean pulp oil treatments, with average moisture levels ranging from 80% to 86%. However, no significant changes in protein and fat content were observed across treatments. These findings suggest that soybean pulp oil, which is rich in polyunsaturated fatty acids, can effectively preserve moisture in high-quality meats like Wagyu beef without affecting its protein or fat composition. The study highlights the potential of soybean pulp oil as a sustainable, natural alternative to synthetic preservatives in premium meat products. By utilizing a byproduct of soybean oil extraction, this approach also contributes to the circular economy and sustainable food production. The study’s findings have significant implications for the meat processing industry, especially in response to increasing consumer demand for natural food preservation methods. Further research is needed to explore the long-term effects of soybean pulp oil on other sensory attributes of Wagyu beef, such as flavor and microbial stability.
