Abstract

This study aims to develop and evaluate an Augmented Reality (AR)-based diorama learning media to enhance elementary students’ reflective thinking and self-regulation in IPAS learning. This study employed a Research and Development (R&D) approach adapted from Borg and Gall, followed by a one-group pretest-posttest design to examine effectiveness. The participants were third-grade elementary students. Data were collected through expert validation sheets, practicality questionnaires, and reflective thinking and self-regulation test. Data analysis was conducted using descriptive statistics and normalized gain (N-gain). The results indicate that the developed media achieved very high validity (M = 3.76) and practicality (M = 3.81). The effectiveness test shows significant improvement in reflective thinking (N-gain = 0.68) and self-regulation (N-gain = 0.71), both in ranged from moderate to high categories. These study contributes by positioning that the integration of concrete diorama media with AR technology effectively promotes interactive, students-centered learning and supports the development of higher-order thinking skill and learner autonomy. This research contributes an empirically validated instructional media model elementary IPAS context that integrates physical and digital learning environments to enhance both cognitive and self-regulated learning outcomes in elementary IPAS

Abstract

Socioscientific Issues (SSI) integration in science education connects scientific concepts with complex real-world problems while fostering students’ scientific argumentation skills. This systematic review examines SSI integration in science learning, its contribution to students’ scientific argumentation, and the role of digital learning resources.The review followed PRISMA 2020 guidelines and analyzed empirical studies published between 2020 and 2025. Literature searches were conducted in October 2025 using Scopus, ScienceDirect, and Taylor & Francis Online with Boolean operators such as (“socioscientific issues” AND “scientific argumentation”). From an initial pool of 800 articles, 36 studies met the inclusion criteria and were analyzed through thematic synthesis. The findings reveal four dominant SSI integration patterns: scientific discuSSIon and debate, problem- and project-based learning, evidence-based decision-making, and digital instructional media. SSI integration consistently strengthens structural and dialogic argumentation, evidence evaluation, complexity-based reasoning, and consideration of ethical and social dimensions. However, studies integrating SSI into digital instructional resources remain limited. Teacher competence, argumentative scaffolding, and contextual issue relevance were identified as key supporting factors, while limited instructional materials and curriculum pressure became major barriers. These findings provide an empirical foundation for developing SSI-based science instruction and digital learning resources that support scientific argumentation in 21st-century education.

Abstract

Road roughness measurement using the International Roughness Index (IRI) plays a critical role in road asset management, influencing maintenance prioritization and budget allocation. However, discrepancies between instruments may introduce bias without proper calibration. This study aims to analyze the calibration and validation of the Hawkeye 2000 as a Digital Laser Profiler for IRI measurement based on SNI 3426:2022. Calibration was conducted using a Walking Profilometer as the reference instrument, followed by validation on five test segments (SP1–SP5) with lengths of 100–500 meters under three speed variations (40, 50, and 60 km/h). The results show that the Hawkeye 2000 meets the requirements of SNI 3426:2022, with coefficients of determination (R²) of 0.9819 (left), 0.9850 (right), and 0.9820 (combined), indicating high accuracy. The coefficient of variation (CV) ranges from 0.0159 to 0.0241 (<5%), reflecting high precision. Calibration parameters (A = 0.9956; B = −0.0093) are within acceptable limits. The instrument also demonstrates consistent performance across different speeds. In conclusion, the Hawkeye 2000 is reliable for field IRI measurement, although further studies are needed to consider broader road conditions and external factors.

Abstract

Malaria diagnosis accuracy depends on microscopic image quality, often compromised by noise. This study comprehensively evaluates classical denoising (morphological, median, bilateral filters) against deep learning architectures (DnCNN, Autoencoder, U-Net) for malaria parasite images. Using the Cell Images for Detecting Malaria dataset with synthetic Gaussian, salt-and-pepper, and mixed noise, experiments measured PSNR, SSIM, and processing time. Results indicate U-Net achieved superior performance (PSNR 36.69 dB, SSIM 0.9577), significantly outperforming Autoencoder (PSNR 26.12 dB) and classical methods (PSNR 23.14 dB). The baseline DnCNN architecture did not achieve competitive performance (PSNR 8.42 dB), indicating that domain-specific parameter tuning and data normalization adjustments are necessary for effective application to microscopic imaging. Autoencoder demonstrated the highest computational efficiency (1.64 ms per image), though the 10.57 dB PSNR gap relative to U-Net suggests that the quality trade-off may limit its suitability in accuracy-critical diagnostic scenarios. U-Net best preserved morphological details crucial for diagnosis and is recommended as the primary choice for malaria diagnostic systems prioritizing accuracy, while Autoencoder represents the most computationally efficient alternative for resource-constrained deployment. These findings support developing robust computer-aided diagnosis systems and contribute a comprehensive quantitative benchmark for denoising methods in malaria microscopy.

Abstract

This study aims to develop a valid and reliable assessment instrument for the application of deep learning in high school chemistry instruction. The development of the instrument is based on Wilson’s Four Building Blocks approach (2005), which includes construct maps, items, item scores, and measures. The study was conducted with 271 twelfth-grade students from three public high schools in West Sumatra, selected through purposive sampling. Data were collected using a student perception questionnaire designed based on the four pillars of deep learning implementation: graduate profile dimensions, learning principles, learning experiences, and learning frameworks. Content validity was analyzed using Aiken’s V, while empirical validity and reliability were tested using the Rasch Model. The results showed an average Aiken’s V value of 0.90, indicating excellent content validity. Rasch analysis yielded a respondent reliability of 0.97 and an item reliability of 0.95, with fit statistics within the ideal range and supporting construct unidimensionality. From the initial 116 items, the final instrument consists of 46 items that passed through a rigorous empirical selection process to ensure high measurement quality. Thus, this instrument is suitable for evaluating the level of deep learning implementation at the elementary to intermediate levels in high school chemistry education.

Abstract

This study aims to examine the moderating role of work engagement in the relationship between workplace spirituality (WS) and innovative work behavior (IWB) among general practitioners (GPs). A systematic review and meta-analysis were conducted following PRISMA (2021) guidelines. A comprehensive search across Scopus, Web of Science, PubMed, ProQuest, ScienceDirect, and Google Scholar identified 16,800 records. After removing duplicates (n = 3,215) and screening, seven quantitative studies (N = 3,025 GPs) were included. A random-effects model was applied due to substantial heterogeneity (I² = 91.35%). The results showed a moderate and significant positive relationship between WS and IWB (r = 0.52, 95% CI [0.42–0.60]). A narrative comparison based on study characteristics suggested that work engagement may strengthen this relationship, with stronger associations observed in studies reporting higher employee engagement (r = 0.61) compared to those with lower engagement (r = 0.38). However, formal moderator analysis was limited due to the small number of included studies (k = 7).  Subgroup analysis indicated no significant effect of GP workforce characteristics (p > 0.05). These findings suggest that workplace spirituality enhances innovative behavior through meaning and value alignment, but its effectiveness depends on work engagement. Strengthening both factors may improve physician innovation and support sustainable general practitioners (GPs) aligned with SDG 3.

Abstract

Entomopathogenic fungi are one of the biological agents that play an important role in controlling insect pests. In addition to being obtained from infected insects and the rhizosphere, this group can also associate as endophytes in plant tissues. This study aims to explore endophytic fungi originating from corn (Zea mays L.) in North Sumatra and evaluate their entomopathogenic potential against insects. Plant samples were collected from corn production centers in the lowlands and middlelands of Deli Serdang and Serdang Bedagai Regencies using a purposive sampling method. Isolation was carried out from healthy plant tissues (roots, stems, and leaves), followed by a pathogenicity test using the insect baiting method against Tenebrio molitor larvae. A total of 59 endophytic fungal isolates were successfully obtained, of which 19 isolates showed pathogenic activity against T. molitor. Isolate EK2_23 (Beauveria sp.) showed the highest performance with mortality and mycosis of 85% and 100%, respectively. Morphological identification revealed the presence of four main genera: Beauveria, Metarhizium, Aspergillus, and Trichoderma. This finding confirms that corn endophytic fungi have the potential to be a prospective source of local biological agents for development as mycoinsecticides to control major corn pests.

Abstract

This study examines the relationship between the Christmas tree worm (Spirobranchus sp.) and coral health in tropical reef ecosystems. Field observations and statistical analyses were conducted to evaluate worm abundance and its association with coral condition. The results showed a strong association (Phi coefficient = 0.79) between high worm density and degraded coral health. Juvenile Spirobranchus sp. preferentially settle on healthy coral substrates, while adult individuals may contribute to surface abrasion and localized lesions through opercular movement. Exposed worm tubes can facilitate turf algae colonization, inhibiting coral recovery. Environmental parameters, including temperature, pH, salinity, visibility, and current velocity, influence coral condition and worm distribution. Elevated and localized temperature anomalies and reduced water flow were associated with increased coral stress and algal growth. These findings indicate that Spirobranchus sp. may contribute to coral degradation under high population density. This study supports Sustainable Development Goal 14 (Life Below Water) by highlighting the potential of Spirobranchus sp. density as a practical indicator for coral reef monitoring and conservation.

Abstract

Stroke is a leading cause of death and disability worldwide. Most strokes are associated with modifiable risk factors, such as hypertension, diabetes mellitus, and high cholesterol. These risk factors can be managed through non-pharmacological approaches, such as physical activity and complementary therapies. To analyze the effect of a combination of walking intervention and acupressure therapy on blood pressure, fasting blood glucose levels, and cholesterol levels in patients with stroke risk factors. Methods: This study used a quantitative method with a quasi-experimental two-group pretest–posttest design. A total of 60 respondents from the working areas of the Curup Community Health Center and the Perumnas Community Health Center were divided into an intervention group and a control group. The intervention group received a walking program combined with acupressure therapy and was monitored daily using a checklist. Blood pressure was measured using an Omron digital sphygmomanometer, while fasting blood glucose and cholesterol levels were measured using a Multimeter Auto Check device. Measurements were taken before the intervention and on the 12th day after the intervention. Data analysis used paired t-tests, Wilcoxon tests, and Mann–Whitney tests according to data distribution. Conclusion: There were significant differences in systolic blood pressure, fasting blood glucose levels, and cholesterol levels in the intervention group after the intervention (p < 0.001). However, changes in diastolic blood pressure did not show significant differences during the study period. The Mann–Whitney test also showed significant differences between the intervention and control groups in systolic blood pressure, fasting blood glucose, and cholesterol. Stroke prevention education has a positive impact on controlling stroke risk factors, particularly systolic blood pressure, fasting blood sugar, cholesterol, and knowledge levels. Health behavior monitoring using checklists has been implemented, but increased monitoring intensity is needed to support optimal clinical outcomes.
