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

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.

Abstract

The rapid development of information and communication technology has reshaped science education, offering innovative solutions to overcome the limitations of traditional laboratories. In physics, where abstract concepts are often difficult to observe directly, virtual laboratories provide safe, cost-effective, and interactive alternatives for experimentation. This study employed a qualitative meta-analysis supported by descriptive quantitative analysis to synthesize evidence from studies published between 2018 and 2022 on the use of virtual laboratories in inquiry-based physics learning. Data were categorized into achievement indicators such as conceptual mastery, critical thinking, problem-solving, and misconception reduction, and analyzed using descriptive statistics and thematic synthesis. The results indicated a substantial improvement in student performance, with mean scores increasing from 66.42 before intervention to 80.35 afterward, alongside a reduction in achievement gaps across ability levels. Conceptual mastery (25%) and conceptual understanding (20%) were the most frequent outcomes, while higher-order thinking indicators collectively represented 30%. Optics and electricity were the most frequently supported topics, reflecting the strength of simulations in visualizing abstract phenomena. The findings confirm that combining inquiry pedagogy with virtual laboratories yields stronger learning outcomes than either approach alone. This study implies that virtual laboratories can democratize access to experimental learning while fostering essential 21st-century competencies in resource-limited educational contexts.

Abstract

The advancement of science and technology has significantly transformed human life, and among the most essential phenomena underlying these developments is magnetism, which has long served as both a theoretical foundation and a practical enabler of innovation. This study employed a descriptive qualitative design through an extensive literature review of academic books, peer-reviewed journals, and reputable online resources to analyze the principles of magnetism and their applications in daily life. The findings reveal that magnetic fields are widely utilized in household devices such as refrigerators, electric bells, and loudspeakers, as well as in advanced technologies including electric motors, telecommunication systems, and medical imaging. The results further demonstrate that magnetism is not only central to technological innovation but also provides significant educational value by linking abstract concepts with real-world experiences, thereby enhancing conceptual understanding and student engagement. Comparative analysis with previous studies confirmed the reliability of these findings while highlighting the novelty of this research in synthesizing historical, theoretical, and practical dimensions into a single holistic narrative. The study implies that integrating magnetism into science curricula and leveraging its practical relevance can strengthen science literacy and foster innovation, while also underscoring the potential of magnet-based systems for advancing sustainable energy and engineering solutions.
