Abstract

This study explores how extractive content in lignocellulosic biomass affects syngas quality during fixed-bed pyrolysis-gasification, specifically focusing on hydrogen (H₂) concentration. While woody biomass is a known energy source, the link between its non-structural organic compounds (extractives) and H₂ in syngas is often overlooked. We investigated teak, coconut, and jackfruit wood to understand this influence and optimize temperature for better biomass-to-hydrogen conversion. An MQ-8 sensor detected H₂ levels. Results show that biomass with high extractive content significantly boosts syngas H₂. Jackfruit wood yielded the highest H₂ concentration (2898 ppm at 471°C), outperforming coconut wood (1965 ppm at 444°C) by 41.7% and teak wood (1931 ppm at 395°C) by 50.1%. This is due to jackfruit's high cellulose and extractive content, which decompose efficiently at higher temperatures. Overall, high-extractive biomass improves syngas quality and expands sustainable options for hydrogen production.

Abstract

This study aims to analyze the use of digital-based media in enhancing the professional competence of teachers at SMAN 5 Batam. Teacher competence is crucial for improving the quality of learning, and digital technology offers potential strategies for professional development. The research employed a quantitative approach, using descriptive and inferential analyses, with simple linear regression to examine the relationship between digital media use and teacher competence. The results show that integrating digital media positively impacts teachers’ knowledge, pedagogical skills, and learning innovation. The study found a strong correlation between digital media use and professional competence (r = 0.770) and a coefficient of determination of 58.83%, indicating that digital media contributes significantly to competence improvement. Despite these positive outcomes, several challenges were identified, including limited infrastructure, insufficient ongoing training, and resistance to adopting new technologies. The findings suggest that the effective use of digital media can enhance teacher competence when supported by proper policies, continuous training, and capacity-building programs. This research highlights the strategic role of digital technology in teacher development and provides empirical evidence that supports the integration of digital media as a tool to foster professional growth and innovation in education.

Abstract

This study aims to examine the effect of implementing the Archerys ID Model instructional design and student learning motivation on physics learning outcomes. The Archerys ID Model, developed from the ARCS motivational framework, incorporates reflection and the formation of learning habits to enhance both engagement and academic integrity. A quasi-experimental method with a 2×2 factorial design was employed, involving an experimental group taught using the Archerys ID Model and a control group using the TPACK model. Data were collected through learning motivation questionnaires and standardized physics tests, then analyzed using two-way ANOVA to assess main effects and interactions. The results showed that students taught with the Archerys ID Model achieved significantly higher learning outcomes than those in the TPACK group. Learning motivation also had a significant effect on student performance, while no interaction was found between the instructional model and motivation levels. These findings indicate that the Archerys ID Model is effective in improving learning outcomes, particularly when combined with strategies that promote intrinsic learning engagement.

Abstract

Learning media is one of the supports in growing and increasing students' interest in learning. However, based on the results of initial research through interviews conducted at SDN 14 Labuah, Tanjung Raya District, Agam Regency, it was found that the school did not have adequate learning media and did not utilize them well. Teachers only used existing textbooks and used the whiteboard as a medium for delivering lesson materials. This study aims to develop interactive e-comic learning media for mathematics subjects on the material of integer addition operatioans for third-grade elementary school students. The background of this study is the low interest and learning outcomes of students (only 40% achieved the KKM) at SDN 14 Labuah due to inadequate learning media. This study uses the 4D model Research and Development (R&D) method, which includes the Define, Design, Development, and Disseminate stages. However, this study focuses on the Development stage, namely validation and practicality tests. Data collection was carried out through observation, interviews, and questionnaires. The results showed that the e-comic media was declared highly feasible with validation scores of 85.71% from media experts, 88.64% from material experts, and 91.66% from language experts. Furthermore, this media was also deemed highly practical based on teacher (93.18%) and student (93.75%) responses. Thus, it was concluded that this e-comic media is feasible to use and highly effective as a mathematics learning medium in grade III of elementary school.
