Abstract

Brain tumors are abnormal cell growths in brain tissue that can be life-threatening. This study aims to classify brain tumors to help early diagnosis. The method used is to extract features from brain MRI images using Local Binary Pattern (LBP) and then classified with Support Vector Machine (SVM). The data used were 2044 brain MRI images consisting of 3 classes namely meningioma, no tumor, and pituitary. The best results were obtained using LBP with a radius of 1 and the number of neighbors 8, while the best SVM model used the RBF kernel with a C value of 50, resulting in 88% accuracy, 86% precision, and 87% recall. It can be concluded that the combination of LBP and SVM methods is effective enough to classify brain tumor types to support early diagnosis.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh evaluasi pembelajaran terhadap peningkatan motivasi belajar matematika siswa kelas VIII di SMP Swasta Ar-Rahman. Pengumpulan data dilakukan melalui angket yang mencakup beberapa aspek evaluasi, seperti frekuensi pemberian evaluasi oleh guru, pemahaman siswa terhadap materi setelah evaluasi, serta dampak evaluasi terhadap motivasi belajar. Hasil penelitian menunjukkan bahwa 45,8% siswa menyatakan guru sering memberikan evaluasi setelah pembelajaran, dan 50% siswa merasa bahwa evaluasi membantu mereka memahami materi dengan lebih baik. Selain itu, 45,8% siswa menyatakan termotivasi untuk belajar lebih giat setelah evaluasi, sementara 41,7% merasa lebih percaya diri dalam menghadapi pelajaran matematika.Penelitian juga menemukan bahwa 50% siswa menyatakan guru sering menjelaskan tujuan evaluasi sebelum pelaksanaan, dan 41,7% merasa evaluasi tersebut sesuai dengan kemampuan mereka. Sebanyak 50% siswa menyatakan bahwa umpan balik dari guru setelah evaluasi jelas dan bermanfaat. Secara keseluruhan, hasil penelitian menunjukkan bahwa evaluasi pembelajaran yang konsisten dan adil dapat meningkatkan motivasi belajar siswa. Umpan balik yang relevan dan jelas juga berperan penting dalam membangun kepercayaan diri siswa terhadap kemampuan mereka dalam memahami matematika.

Abstract

This research aims to (1) determine the characteristics of social and moral development in elementary schoolaged children, and (2) to determine the implications of children's social and moral development for the formation of social attitudes in elementary school-aged children. The research method used in this research is research by direct observation. The results of the research show that the social and moral development characteristics of elementary school children are aware of the social roles, religion, race and socio-economic status of their peers, accept cultural stereotypes and adult attitudes towards This status gives rise to group awareness in behaving in their social environment. These characteristics will remain until childhood and will continue until they are adults if educators provide stimulus to continue their developmental tasks in a mature manner. This stimulus takes the form of guidance, direction, and provides a good and healthy social and cultural environment for social, emotional and moral development so that it has implications for the formation of good social attitudes. Keywords: social development, moral development, elementary school students
