Abstract

Learning outcomes are important for students. In the implementation of learning in schools, efforts to improve student learning outcomes experience many obstacles and barriers. This study aims to test the effect of the Dick & Carey instructional design model and learning attitudes on students' science learning outcomes. This instructional design model is expected to improve students' science learning outcomes compared to the TPACK instructional design model. The type of research used is a quasi-experiment with a Treatment by Block design. This study involved 2 classes, the experimental class, namely the class that was given treatment with the application of the Dick & Carey instructional design model, while the control class was the class that used the TPACK instructional design model. The results of the data analysis showed that students who were taught with the Dick & Carey instructional design model, both those with good or bad attitudes, obtained significantly higher learning outcomes than the science learning outcomes of students taught with the TPACK instructional design model. And there is the effectiveness of the application of the Dick & Carey instructional design model and learning attitudes towards student learning outcomes. In general, learning with the Dick & Carey instructional design model is more effective than learning with the TPACK instructional design model.

Abstract

This study addresses the gap in understanding the effectiveness of deep learning approaches in geography education, particularly in higher education contexts where such methods are not yet fully integrated. The aim of this study was to explore students' perceptions of deep learning in geography courses, focusing on its impact on their understanding of the subject, critical thinking, student engagement, and the role of technology. A quantitative descriptive research design was employed, utilizing a structured questionnaire administered to 100 geography students from a university in Indonesia. The questionnaire explored five key areas: understanding of deep learning, deep learning-based instructional processes, student engagement, the use of technology, and the development of higher-order thinking skills. The results showed that students perceived deep learning as effective in enhancing their understanding of geography, improving critical thinking skills, and increasing engagement in the learning process. Students also recognized the importance of integrating technology, such as digital tools and geospatial data, in fostering deeper learning experiences. However, while students expressed positive perceptions, the study highlighted the need for further professional development for educators in applying deep learning strategies effectively. In conclusion, deep learning has the potential to significantly enhance geography education by fostering deeper engagement, critical thinking, and the use of technology. It is recommended that higher education institutions invest in training faculty members to integrate deep learning methods into their teaching practices and that future research explore the long-term effects of deep learning on academic performance and real-world applications in geography.

Abstract

Estimation of photovoltaic cell parameters from experimental data is an important part of photovoltaic system performance modeling and optimization. This study aims to estimate the parameters of photovoltaic cells. The photovoltaic models used are the one-diode model (ODM) and the two-diode model (TDM). Optimization is performed using the moth-flame optimization (MFO) algorithm. The root mean square error (RMSE) method is applied to determine the accuracy of the estimated parameters. Experimental results show that the MFO algorithm is able to obtain photovoltaic cell parameters with a high level of accuracy, both in ODM and TDM. The current-voltage  (I-V) and power-voltage (P-V) curves between the measured and estimated data also show a very good match. In addition, the optimization algorithm outperforms most metaheuristic algorithms applied in photovoltaic cell parameter determination. Thus, the MFO algorithm is suitable to be applied in determining the photovoltaic cell parameters.

Abstract

The research problem is commodity prices, especially at harvest time. The Upland project aims to increase potato production and quality as well as improve access to markets and better selling prices.  This study aims to identify the value chain and its stakeholders, create a graphic design of the value chain in the form of potato marketing channels and analyze the margins in each marketing channel. The research was conducted in Modoinding District, South Minahasa Regency. Sampling using snow ball sampling method, data collection using interview, observation and documentation methods. The results showed that there are 3 levels of marketing channels, including: (1) marketing channel level 0 (farmers - consumers); (2). marketing channel level 2 (farmers - village intermediary traders - inter-island traders - consumers; and there are also farmers - village intermediary traders - large retailers in Modoinding - consumers); and (3) marketing channel level 3 (farmers - village intermediary traders - large traders - inter-island traders - consumers).  The results of the margin analysis showed that the farmer's acceptance value was 100% and the value at the consumer level increased due to the difference in margins with df stakeholders in the marketing channel. The value chain of potato commodities in the South Minahasa Upland Project has the highest margins when farmers sell directly to consumers, and in channels where there is a role of inter-island traders, the highest margin value compared to village intermediaries and large traders.

Abstract

This study investigated the effect of Mathematics Games and learning motivation on the mathematics achievement of fifth-grade students at SDN 03 Koto Kaciak. Using a quantitative approach with a 2×2 factorial quasi-experimental design, students were assigned to experimental and control groups. Data were collected through pre- and post-tests and a learning motivation questionnaire. Two-way ANOVA was used for analysis. The results showed that the Mathematics Games method did not significantly affect learning outcomes (p > 0.05), although the experimental group demonstrated slightly higher mean scores than the control group. In contrast, learning motivation significantly influenced students’ mathematics achievement (p < 0.05), with high-motivation students outperforming their peers. No significant interaction was found between teaching method and motivation level. These findings suggest that while the Mathematics Games method did not produce statistically significant gains, learning motivation remains a key factor in academic success. The study’s contribution lies in its contextual application of Mathematics Games as an instructional strategy in a rural elementary school setting, highlighting the importance of implementation quality and learner characteristics. Further research with longer treatment duration and larger samples is recommended to assess long-term effects and refine the integration of educational games in elementary mathematics instruction.
