Abstract

The research problem is that students often memorize science concepts without deep understanding, leading to low metacognitive awareness and an inability to solve new problems like corrosion topics. This study aims to measure improvement in metacognitive awareness and cognitive learning outcomes through Project-Based Learning (PjBL). The research method is that a quasi-experimental method with a one-group pretest-posttest design was employed. The participants were fourth-semester mechanical engineering students at UNHASY. Data were collected using a metacognitive awareness questionnaire and a cognitive learning test, administered before and after the PjBL intervention. The data were analyzed quantitatively using a Paired Sample T-Test to determine the significance of the differences between the pretest and posttest scores for both metacognitive awareness and learning outcomes. The research results showed significant improvement in both metacognitive awareness (t=4.70, p<0.05) and learning outcomes (t=4.87, p<0.05). It is concluded that Project-Based Learning is an effective instructional model for fostering metacognitive awareness and improving academic achievement in science education. Its implementation is highly recommended to develop higher-order thinking skills and deeper conceptual understanding.

Abstract

The rapid shift toward 21st-century learning requires prospective primary teachers to master science process skills (SPS) that support critical thinking, problem-solving, and innovation. This study aims to analyse PGSD students’ SPS and 21st-century skills through a reflective approach. A descriptive qualitative design supported by quantitative data was employed. Data were collected from 22 first-year PGSD students enrolled in an elementary science education course using a Likert-scale questionnaire and written reflective journals. Questionnaire data were analysed descriptively using mean scores and categorical achievement levels, while journal data were examined through thematic analysis. The results show that students’ SPS are at a very high level (M = 4.21), particularly in observing, conducting experiments, drawing conclusions, and applying scientific concepts. Their 21st-century skills are at a high level (M = 4.19), with collaboration and critical thinking higher than creativity and communication. Reflective journals confirm that practice-based and project-based science activities help students recognise their strengths and weaknesses and plan improvements. It can be concluded that reflective, experiment-oriented science learning effectively develops SPS and 21st-century skills in prospective primary teachers, although communication and creativity still need systematic reinforcement

Abstract

The global fossil fuel crisis and demand for sustainable renewable energy sources have driven the development of biomass-based alternative fuels. Cascara, a coffee husk by-product with high cellulose content and wide availability, has strong potential for conversion into biomass briquettes; however, improvements in fuel quality and energy conversion efficiency are needed. This study aims to improve the physical, thermal, mechanical, and emission performance of cascara briquettes by varying the composition of cascara leaves, bletong, and Tectona grandis, as well as integrating the optimized briquettes as a heat source in a thermoelectric generator (TEG) system. This study also evaluates the effectiveness of applying a STEM-based Research-Based Learning (RBL-STEM) model in improving students' creative thinking skills. This study was conducted in two stages. The experimental stage used a completely randomized design with ten briquette formulations and tested the calorific value, combustion rate, impact strength, and emissions. The learning stage applied the research results to 35 students using a single-group pretest-posttest design. The data were analyzed using instrument validation, normality tests, correlation analysis, and paired sample t-tests. The best formulation (70:20:10) produced the highest calorific value, while 50:30:20 produced the lowest emissions. The implementation of RBL-STEM significantly improved students' creative thinking performance.

Abstract

The main problems faced by the organization are undelivered SLA performance, non-standard quality between vendors in different areas nationally, and no standard in outsourcing of certain selected vendors. This study aims to optimize the vendor selection and standardization process in the EDC machine supply chain process at PT. XYZ, by utilizing the IT Governance approach using COBIT 2019. By using a research methodology with qualitative and quantitative approaches, this study analyzes the gap between Vendor Governance by utilizing the main domains of COBIT 2019, especially in APO10 (Managed Vendors), DSS01 (Managed Operations), and MEA01 (Monitoring Performance). This process includes mapping Enterprise Goal to Alignment Goal and selecting the relevance domain to be used, and measuring the process Capability Level using Level 0-5. The results of the study show that more of several key activities in the APO10, DSS01 and MEA01 domains are still at capability levels 2 and 3, indicating that some activities are not well documented consistently in some areas. Therefore, the novelty of this research is conveyed by making a performance assessment based on Simple Weighted Average (SAW) as part of the Multi Criteria Decision Making (MCDM) model, performance scorecard, vendor evaluation and vendor rationalization simulation to enforce efficiency and improve service quality.

Abstract

The digitalization of chemistry education is crucial for ensuring inclusivity and equal learning opportunities, particularly for students with intellectual disabilities. This study investigated students’ functional learning profiles through digital student worksheets (e-LAPD) on atomic theories, integrated with individualized strategies based on Universal Design for Learning (UDL) via the Liveworksheet platform. A mixed-methods approach with a concurrent embedded design was applied, involving three students with intellectual disabilities at SMAN 10 Surabaya. Qualitative data were collected through semi-structured interviews and classroom observations, then thematically analyzed using NVivo 11, which yielded two major themes: the implementation of e-LAPD and students’ learning profiles. The analysis revealed that the implementation of e-LAPD effectively supported students’ understanding of the development of atomic theories, as evidenced by quantitative results obtained from questionnaire responses and pre-test/post-test instruments. Questionnaire data indicated that 100% of students reported improved conceptual understanding through e-LAPD. Furthermore, pre-test and post-test results showed a significant improvement with a high average N-gain score of 0.88. In addition, the findings highlighted students’ learning abilities and learning profiles, such as their tendency to engage with interactive visual media, their preference for verbal explanations, and their reliance on physical interaction during learning activities.

Abstract

The Batang Arau River in Padang City exhibits contrasting environmental conditions between its upstream and downstream segments. The upstream–midstream areas still maintain good water quality with positive carrying capacity, while the downstream segment has exceeded its natural assimilation limit due to increasing pollutant loads originating from domestic and community activities. This study aims to analyze water quality, calculate carrying capacity, and model the relationship between community behavior and the river’s assimilation capacity using a system dynamics approach. The modeling results indicate a continuous decline in carrying capacity driven by population growth and waste generation, illustrating that human behavior has a direct impact on the ecological balance of the river. Therefore, sustaining the ecological function of the Batang Arau River requires integrated pollution control policies, community-based waste management, and continuous environmental education to enhance public awareness and ensure the long-term sustainability of the river ecosystem.

Abstract

Stunting remains a public health problem in Indonesia with long-term impacts on health, education, and productivity. Prevention efforts starting from adolescent girls are crucial because mothers' knowledge influences the risk of stunting in the next generation. This study aimed to assess the effectiveness of Artificial Intelligence (AI)-based educational videos in improving adolescent girls' knowledge about stunting prevention. A quasi-experimental pretest–posttest design was conducted on 72 respondents, selected proportionally from the student population. The intervention took the form of education through AI-based video media, with respondents' knowledge measured before and after the intervention, and then analyzed using paired statistical tests. The results showed that the average knowledge score increased significantly from moderate to high after the intervention (p < 0.05). These findings support previous studies that confirm the effectiveness of digital media and AI in improving adolescent health literacy. In conclusion, AI-based video media are effective in increasing adolescent girls' knowledge about stunting prevention and have the potential to be integrated into health education programs as a preventive strategy to reduce the prevalence of stunting in Indonesia.

Abstract

Lahar floods are among the most destructive secondary volcanic hazards and often cause severe disruption to communities and schools in affected areas. This study aimed to analyze students’ experiences of lahar disasters, their level of self-awareness, and the relationship between both variables. The research was conducted at MTsN 7 Tanah Datar, one of the schools directly affected by the 2023 Mount Marapi lahar flood, using a quantitative correlational method. Data were collected from 150 students through a structured questionnaire covering indicators of direct experience, knowledge of lahar characteristics, preparedness, emotional awareness, accurate self-assessment, and self-confidence. The results showed that students’ disaster experiences were generally high, especially in direct experience (70%) and knowledge of lahar characteristics (85%), while preparedness remained moderate (60%). Students’ self-awareness was also mostly in the moderate category across emotional awareness, self-assessment, and self-confidence. Pearson correlation analysis indicated a positive and significant relationship between lahar disaster experience and students’ self-awareness, although the correlation strength was low. These findings demonstrate that direct exposure to lahar events plays a role in shaping students’ self-awareness; however, their practical preparedness and confidence still require strengthening. Therefore, the study concludes that enhanced disaster education—particularly through simulations and practice-based learning—is essential to improve students’ self-awareness and readiness in facing lahar floods.

Abstract

This study aimed to analyze the comparative effectiveness of e-learning videos created by course lecturers versus externally produced videos in enhancing nursing students' cognitive and psychomotor skills regarding psychiatric nursing care for clients at risk of violent behavior. A quasi-experimental design with a pretest-posttest approach was employed. Student cohorts were divided into an intervention group, which used lecturer-made videos, and a control group, which used externally made videos. The findings revealed a substantial improvement in the intervention group, with cognitive skills increasing by 86.5% and psychomotor skills by 69.77%. In contrast, the control group showed no significant increase. This indicates that lecturer-created videos, likely due to their tailored relevance to the specific curriculum and learning context, are a more potent educational tool. It is concluded that e-learning videos developed by the course lecturers are significantly more effective than external videos in improving both the knowledge and practical skills of nursing students. The use of curated, internally developed video media is therefore highly recommended for optimizing learning outcomes in specialized nursing education.

Abstract

Misconceptions in elementary science education are a persistent challenge embedded in the cognitive architecture and neurodevelopmental trajectories of young learners. This comprehensive analysis examines the phenomenon of science misconceptions in elementary school students through the integrated lens of cognitive processing theory and brain development research. By synthesizing contemporary neuroscience findings with an established cognitive psychology framework, this article elucidates the neurobiological underpinnings of misconception formation, persistence, and potential remediation strategies. The analysis reveals that misconceptions are not simply learning errors but, rather, systematic constructs arising from the interaction of developing neural networks, limited cognitive resources, and intuitive reasoning patterns. Limited prefrontal cortex maturity, working memory constraints, and a tendency toward intuitive thinking create a developmental context in which misconceptions naturally emerge. Next, the article explores how neurodevelopmental factors (such as synaptic pruning and executive function development) influence the process of conceptual change. By testing various theoretical frameworks, including conceptual change theory and the dual-process model of cognition, in a neurodevelopmental context, this work provides educators and researchers with a deeper understanding of why misconceptions persist and how evidence-based instructional strategies aligned with brain development can facilitate more effective conceptual understanding. Implications of this study include curriculum design, teacher training, and assessment practices that respect the developmental realities of elementary school students.
