Abstract

This study aims to investigate the effect of the video-assisted Realistic Mathematics Education (RME) model on the learning activities and outcomes of elementary school students. The research employed a quasi-experimental design involving fourth-grade students from two different schools. Data were collected using a questionnaire to measure student learning activities and a test to assess mathematics learning outcomes. The data were then analyzed using appropriate quantitative statistical procedures to evaluate differences and relationships between the variables studied. The findings show that the implementation of the RME model supported by video learning had a significant effect on both learning activities and student achievement in mathematics. Students who participated in video-assisted RME learning demonstrated higher levels of engagement during classroom activities compared to their peers in the control group. In addition, their mathematics test scores were consistently better, indicating an improvement in conceptual understanding and problem-solving abilities. The analysis also revealed a strong and positive relationship between students’ active involvement in learning and their academic performance. These results highlight the potential of combining the RME approach with digital media to foster more interactive and effective learning experiences. The study concludes that the integration of video resources within the RME model can serve as an innovative strategy to enhance student activity and achievement in elementary mathematics education.

Abstract

This study aims to characterize the potential seawater intrusion in the aquifers of the coastal area of Tateli Beach, Manado. A geoelectrical resistivity survey was conducted using a dipole–dipole configuration with 48 potential electrodes spaced 10 m apart. The data were processed using RES2DINV software to generate two-dimensional resistivity sections. The resistivity values were correlated with groundwater quality data from nearby wells, particularly salinity and electrical conductivity. The modeling results revealed a low-resistivity zone (≤10 ohm·m), interpreted as a water-saturated aquifer down to a depth of approximately 20 m, overlain by a high-resistivity layer (≥5,000 ohm·m) acting as an aquifuge. Groundwater samples indicated salinity values of 0.01–0.02% and electrical conductivity ranging from 208 to 483 µS/cm, which are still classified as freshwater. In addition, a deeper aquifer was identified at around 50 m depth. These findings suggest that no significant seawater intrusion is currently present. The integration of resistivity imaging and groundwater quality analysis supports the conclusion that the aquifers remain preserved, although continuous monitoring is required to detect potential changes due to human activities and climate impacts.

Abstract

This study aims to analyze the effectiveness of the Collaborative Problem Solving (CPS) model with group role division in improving students' conceptual understanding. The research problem focuses on CPS learning that previously did not apply role division, resulting in uneven group activities. This study uses a mixed method with an embedded experimental design, where quantitative data is the main focus through concept comprehension tests, while qualitative data in the form of observations of student activities is used to reinforce the analysis results. Quantitative data analysis was performed using statistical techniques, both descriptive and inferential, to see trends, differences, or relationships between variables, while qualitative data was analyzed through reduction, categorization, and interpretation processes. The results showed that the experimental group experienced a higher increase in cognitive ability compared to the control group. The effect size value of 0.7 indicates that the effect of CPS based on group role division is moderate. Furthermore, observations show that the group roles in the experimental class were more active and responsible than those in the control group. These findings confirm that integrating CPS with effective group role sharing improves student learning outcomes and cognitive abilities, particularly in understanding complex physics topics.

Abstract

The global fisheries supply chain faces challenges related to data integrity, product traceability, and distribution inequality, which impact the achievement of the Sustainable Development Goals (SDGs), particularly SDG 2 (Zero Hunger) and SDG 12 (Responsible Consumption and Production). The main challenges are rooted in three critical pillars: data integrity, product traceability, and distribution inequality. The lack of accurate and transparent fishing data opens up opportunities for illegal, unreported, and unregulated (IUU) fishing, which is seriously depleting fish stocks. The global fisheries supply chain is a complex and vital network, providing a vital source of protein for billions of people worldwide. However, this complex system faces a series of fundamental challenges that threaten environmental sustainability and social equity, and hinder global efforts to achieve the Sustainable Development Goals (SDGs). Blockchain is a disruptive technology that offers transparency and accountability in the supply chain system. This study aims to examine the impact of blockchain technology adoption on food security through fisheries supply chain efficiency, using the Structural Equation Modeling (SEM) method. The results indicate that blockchain has a significant impact on improving logistics efficiency, product traceability, and consumer trust, which indirectly strengthens national food security. Recommendations are directed at synergy between industry players and the government to accelerate blockchain-based supply chain digitalization.

Abstract

Advances in digital technology, particularly the use of podcasts, open significant opportunities for innovation in learning design. This study explores podcast-based learning in the context of teaching thesis proposals for science education students, reviewed from theoretical, philosophical, and evaluative perspectives. Using a literature review and descriptive analysis, various models of podcast-based design were examined with attention to pedagogical and technological dimensions. The findings show that this approach is grounded in constructivist, cognitive, and connectivism learning theories. Philosophically, it reflects progressivism and social constructivism, emphasizing experiential learning, independence, and collaboration. Evaluation results highlight the potential of podcasts to strengthen cognitive abilities, including conceptual and analytical understanding, as well as 21st-century skills such as critical thinking, communication, creativity, and collaboration. The study concludes that podcast development in higher education must align with instructional design principles tailored to student needs and course characteristics. Further research is needed to develop flexible models and assess their long-term impact on students’ academic performance. Importantly, the outcomes provide practical implications for integrating podcasts into science education curricula and for creating evaluation systems that measure higher-order learning outcomes.
