Abstract

Mathematics is a compulsory subject at the secondary school level, especially on matrix material, sometimes students are still difficult to distinguish rows and columns. It is not easy to do multiplications on matrices. Learning media are expected to be a facility that supports learning. This study aims to develop learning tools based on Macromedia flash subject matter matrix class XI. In developing this learning media based on using Research and Development with the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). This research was conducted at Islamic Senior High School (MA) Muallimin Yogyakarta. The research instrument used was a questionnaire. The quantitative data analysis technique calculates the score of the developed learning media's feasibility test results. The results of research on the development of interactive learning media mathematics based on Macromedia flash subject matter matrix XI based on the quality of each indicator in terms of material experts in the excellent category with an average percentage score of 86.84%, in terms of media experts in the category are very feasible with a percentage score an average of 88.33%, and student responses in the exciting category with an average percentage score of 77.37. The learning media based on Macromedia flash subject matter matrix XI class material is very feasible in the learning process.

Abstract

This study analyzes the effect of color space transformation on the performance of MobileNetV2 for rice leaf disease classification using RGB, HSV, CIELab, and their combinations. The RGB color space is used as the baseline representation, while HSV and CIELab are applied to provide alternative representations of color information. In addition, a dual-stream architecture is employed to combine different color spaces for feature extraction. The results show that the choice of color space influences classification performance. In the single color-space scenario, RGB achieves the highest accuracy of 91.42%, while in the combined scenario, the RGB+CIELab model achieves the best performance with an accuracy of 97.00%. These findings suggest that the use of multiple color spaces can provide richer feature representations and may improve classification performance. Furthermore, the results indicate that optimizing input representation plays an important role in improving model performance, particularly when using lightweight architectures such as MobileNetV2. This study shows that color space transformation can improve classification performance in the rice leaf disease dataset used in this study.
