Abstract

This study explores the effectiveness of the Student Teams Achievement Divisions (STAD) cooperative learning model, supported by flashcard media, in enhancing student learning outcomes in Manufacturing Technical Drawing at SMK Negeri 1 West Sumatra. A quasi-experimental control group design was employed, where the experimental group used the STAD method integrated with flashcards, and the control group received traditional lecture-based instruction. Post-test results showed that the experimental group significantly outperformed the control group, achieving a higher mean score of 79.68 compared to 63.84, with an N-Gain score of 50.81%, indicating moderate improvement. The study found that the STAD model, combined with flashcards, boosted academic achievement and promoted more consistent and equitable learning outcomes. Flashcards played a vital role by simplifying complex concepts and enhancing student engagement. This study fills a gap in vocational education by demonstrating the effectiveness of combining cooperative learning and visual aids in technical education. The research offers valuable insights for educators in similar contexts, proposing a cost-effective and scalable instructional method that can be applied across various technical disciplines. However, the study’s limitation lies in its short-term implementation, and further research is needed to explore the long-term effects of this combined learning strategy.

Abstract

This experimental study investigates the effect of air supply configurations on the combustion performance and thermal efficiency of wood pellet briquettes in rocket stoves for household energy use. With increasing global demand for energy and the depletion of fossil fuels, the shift to renewable biomass fuels, such as wood pellets, is essential to reduce carbon emissions and enhance energy efficiency. The study evaluates four airflow configurations: right fan only (F3), lower-left + right fans (F2+F3), two left fans (F1+F2), and all fans (F1+F2+F3). The results show that the F3 configuration achieved the fastest boiling time, highest boiling temperature, and lowest heat-loss temperature, indicating superior thermal performance. In contrast, configurations with higher airflow (F1+F2 and all fans) led to greater heat losses and slower boiling times, suggesting that excessive airflow can negatively affect efficiency. Additionally, the analysis of residual mass revealed that F3 and F2+F3 configurations produced the lowest residuals, indicating more complete combustion. This study provides important insights into optimising airflow configurations to improve the efficiency of biomass stoves. The findings offer practical implications for the design and operation of sustainable cooking technologies, promoting energy efficiency and reducing reliance on fossil fuels in households, particularly in rural areas.
