Abstract: Research in the field of imaging, especially in medical terms, is expected to have a positive impact on the treatment and diagnosis of diseases in the medical world. Medical image classification is a topic that is often researched, this is indicated by the many national and international journals that discuss this topic. Research on medical image classification using Convolutional Neural Network (CNN) usually focuses on the use of maximum parameters (hyper parameters) to get the best results. However, those that use minimal parameters and the smallest resources are still lacking. Based on the existing problems, it is carried out to obtain optimization in the medical image classification process. The classification of medical images in this study focuses on brain tumor images consisting of three classes, namely meningioma, glioma and pituitary tumor. The approach taken in this study is to use the CNN model and Adaptive Moment Estimation (Adam) Optimizer. The study was conducted by combining the smallest parameters from the Adam Optimizer. The parameters combined are Epoch and Convolution Layer. Where 3 Epoch categories (1,5,10) and 5 convolution layers (1,2,3,4,5) are used. From the tests carried out, the highest accuracy results obtained were 92.8% with epoch parameters of 10 and three convolution layers. Meanwhile, the highest average accuracy was recorded at 90.7% with epoch parameters of 10. The fastest computation time required for model creation was 24.83 seconds, and the lowest CPU resource usage during the model creation process was 16.45%.

Curriculum evaluation is a strategic step in ensuring the quality of education. This article examines various aspects of curriculum evaluation through a literature review of academic sources published between 2020 and 2024. The findings indicate that the most frequently criticized aspects of curriculum implementation include the misalignment of instructional content with students' needs and characteristics, as well as the limited relevance of curriculum content to advances in knowledge and labor market demands. In addition, qualitative evaluation models—such as in-depth interviews and participatory observation—are recommended, as they are capable of capturing dimensions of the learning process that are often overlooked by quantitative approaches. This review highlights the importance of selecting appropriate evaluation models as a foundation for continuous improvement and the development of a curriculum that is more adaptive to change.
