Abstract

Cell Biology is a crucial yet challenging subject in which students often struggle with abstract concepts, particularly cell organelles, a difficulty exacerbated by traditional teaching methods that utilize static materials, which yield inadequate results, especially among students with limited visual-spatial abilities. This research investigated the preliminary needs of both students and lecturers for the development of the NanoPintar e-module using diverse data collection methods, including questionnaires, interviews, student visualization tests, and multiple intelligence assessments. The results indicated very low scores in student visualization and multiple intelligence tests; however, interview and questionnaire outcomes strongly confirmed that both students and lecturers require a NanoPintar e-module for the Cell Biology course, identifying the Endoplasmic Reticulum material as the most difficult topic and thus highly suitable for the development of the e-module

Abstract

Forecasting earthquakes is still one of the most difficult problems in geophysics, mainly because seismic activity is irregular and often influenced by many factors that interact in complex ways. In this study, we develop a leakage-controlled hybrid ensemble model that combines CatBoost, LightGBM, XGBoost, and Gradient Boosting to predict five earthquake parameters: magnitude, depth, latitude, longitude, and a scaled inter-event interval in Northern California. These models were trained using USGS earthquake data ranging from 1900 to 2025 (M ≥ 4.0), with a process designed to prevent time leakage through strict time separation, a moving window feature, and prospective validation. Overall, the hybrid models produced consistently low MAE and RMSE values ​​and very high R² values ​​(above 0.99) for all target variables. While the estimates performed impressively, the results should be interpreted in a probabilistic context, with recognition of the inherent uncertainty of seismic processes. The framework proposed here provides a clear and replicable approach that can support the development of systems for more reliable short-term earthquake forecasting

Abstract

This study explores teachers' readiness and perceptions regarding the integration of Augmented Reality (AR) in STEM education. The research, conducted with 250 teachers from Indonesia and Malaysia, uses an explanatory survey design and Structural Equation Modeling (SEM) to analyze a framework combining Teacher Readiness, the Technology Acceptance Model (TAM), and Deep Learning Orientation. The results reveal that Teacher Readiness significantly influences Perceived Ease of Use (β = 0.48) and Perceived Usefulness (β = 0.42), which in turn affect Attitude Toward Use (β = 0.31) and Behavioral Intention (β = 0.52). Behavioral intention strongly predicts Deep Learning Orientation (β = 0.57). The model explains 56% of the variance in Behavioral Intention and 32% in Deep Learning Orientation. Multi-group analysis shows that these findings are consistent across countries, genders, education levels, and age groups, demonstrating the robustness and generalizability of the model. This research highlights the importance of teacher readiness in adopting AR technology, which fosters deeper learning in STEM education

Abstract

Plant Physiology Education often faces challenges in visualizing complex internal and conceptual processes, such as photosynthesis, transpiration, and mineral nutrition. Traditional teaching methods often fail to motivate students and facilitate in-depth understanding. Investigation of AR and VR Technologies in Plant Physiology Education. This study employed a quantitative methodology with a descriptive design and correlational analysis, involving 50 students who completed a questionnaire regarding their motivation and comprehension of interactive digital books utilizing Augmented Reality (AR) and Virtual Reality (VR). The findings indicated a substantial enhancement in students' motivation and comprehension following the utilization of this technology. The Pearson correlation test indicated a positive link between students' motivation and comprehension, with a significance level of p-value <0.01. The t-test further validated a significant disparity in students' motivation and comprehension when utilizing AR and VR. This technology facilitates a more dynamic and immersive learning experience, aiding students in comprehending complex principles of plant physiology that are challenging to grasp through traditional techniques. This study advocates for the utilization of augmented reality (AR) and virtual reality (VR) technologies to enhance the quality of education in biology, particularly in the area of plant physiology

Abstract

This study addresses the "pedagogical digital gap" by proposing a shift from using technology for content delivery ("scanning") to cognitive support ("scaffolding"). It investigates the effectiveness of a QR-Code Integrated Inquiry model on pre-service primary teachers' critical thinking skills. Employing a quasi-experimental design with 60 participants, data were analyzed using ANCOVA. Findings revealed a highly significant difference () between groups. The experimental group achieved a notably higher adjusted mean (57.43) compared to the control group (34.88), with a massive effect size (). The intervention successfully reduced extraneous cognitive load, facilitating deep reasoning consistently across genders and science topics. The study concludes that re-engineering simple technology as scaffolding creates a robust, inclusive learning ecosystem for teacher education

Abstract

The fast evolution of artificial intelligence (AI) systems has worried people about their environmental impact thus prompting the rise of Green AI. In the present systematic review, we are going through the 32 articles published in peer-reviewed journals that were analyzed based on PRISMA standards regarding the conceptual bases, applications, and the future of Green AI. The review identified three paradigms: Green AI (computational efficiency), Sustainable AI (holistic socio-technical responsibility), and AI for Green (AI applied to sustainability challenges). A large part of the resources that would be used for the environments, monitoring, agriculture, and smart city applications can be saved by 15-30% through Green AI. The main difficulties are performance and efficiency balancing, limiting budget, and a research mentality that values precision more than sustainability. The research points out the dual function of AI in environmental matters as that of polluter and of a device for making the planet greener through humane practices and technologies. To sustainable AI, efficient algorithm design, regulatory support, the establishment of carbon-aware metrics, and collaboration among different disciplines to create the adoption of AI that is both economical and ethical are needed

Abstract

This study aimed to characterize the relaxivity profiles of pure agarose and gadobutrol in 1% (w/v) agarose under two experimental conditions (within the air and tap-water immersion). T1 and T2 values were quantified at 3 Tesla, Siemens, Vida scanner using inversion recovery turbo spin echo (IR-TSE) for T1 and multi-echo turbo spin echo (ME-TSE) for T2. Different concentration of agarose (0.2 – 4.0% w/v) and gadobutrol (0.5 – 6.0 mM) and their T1 and T2 value for each concentration were measured. Pure agarose demonstrated low longitudinal relaxivity (r1 » 0.04 - 0.05 s-1.(%w/v)-1 vs. r1 » 2.97 - 3.52 s-1mM-1) and high transverse relaxivity (r2 » 5.00 - 6.34 s-1.(%w/v)-1 vs. r2 » 3.80 - 4.55 s-1mM-1) compared to gadobutrol. Agarose showed a very high r2/r1 ratio (129.4-160.0) than gadobutrol (1.28-1.29), reflecting stronger gel-matrix effects on transverse dephasing than on longitudinal recovery. Tap-water immersion had shortened T1 by »9% relative to air, without significantly increasing variability. These findings provide relaxivity values for agarose and gadobutrol under well-defined conditions and illustrate how their complementary relaxation behavior can tune T1 and T2 values over a wide range to create customizable MRI calibration phantom for research and clinical use

Abstract

Digital transformation in education has not been optimally utilized to enhance students’ cultural literacy and character development in junior high school Social Studies (IPS). The limited availability of digital learning materials integrating local wisdom has contributed to weak cultural literacy and insufficient character education. This study aims to analyze the need for developing local wisdom-based digital learning materials to improve students’ cultural literacy and character in Social Studies learning in Sijunjung Regency. Using a Research and Development approach with the Borg and Gall model, data were collected through Focus Group Discussions, questionnaires, interviews, and observations involving 10 Social Studies teachers and 153 students from six junior high schools. The findings indicate that Social Studies learning remains largely textbook-centered, with minimal integration of local culture. While 88% of students show interest in digital-based learning, only 34% are familiar with the Marosok tradition, and 90% of teachers have not used culturally integrated digital materials. These results reveal a gap in cultural literacy and highlight the need for contextual digital learning materials that integrate Social Studies content with local values

Abstract

This study examines how gamma radiation (0–50,000 Gy) affects SAC305 (Sn‑3.0Ag‑0.5Cu) solder. Solder joints were irradiated using a Co‑60 source. Structural changes were evaluated by X‑ray diffraction and microstructural evolution were observed with optical microscopy after etching. XRD of β‑Sn reflections indicates smaller crystallite size with dose, together with higher lattice strain and greater dislocation density, consistent with crystal‑level alteration under irradiation. Microstructure observations show coarsening of β‑Sn grains and thickening of the Cu₆Sn₅ intermetallic (IMC) layer at the Cu/solder interface as dose increases. These outcomes reveal a two‑scale response: nanoscale coherent domains refine due to defect formation and accumulation, while microscale grains grow and the IMC layer thickens due to radiation‑enhanced diffusion, which increases atomic mobility. Recognizing that the system involves different length scales helps resolve the apparent contradiction between the decreasing crystallite size and the increasing grain size. Practically, the combined increases in lattice strain, dislocation density, and IMC thickness may reduce reliability and fatigue life of SAC305 solder joints in high‑radiation environments such as space and nuclear applications
