Abstract

The selection of departments in vocational high schools (SMK) is a must for students to determine the concentration of student learning interest for three years in a school. The lack of student knowledge and outreach about this department caused many students to choose their majors by the most choices and following other students. This problem can cause some difficulties for the students to participate in learning, and most fail. Students must select their major based on their interests, abilities, and talents because every student has different abilities and talents. The C4.5 algorithm can provide convenience in grouping students based on majors. Using the decision tree method with attributes such as grades in mathematics, English, interests, and talents, the system can recommend majors based on students' interest levels. The results of this study are the determination of the departments with the accuracy of the calculation using the confusion matrix method with a 98,55% accuracy rate and 100% recall rate value.

Abstract

Kemajuan teknologi yang berkembang, teknologi informasi khusus, mendorong orang untuk mengembangkan media yang dapat digunakan kapan saja dan di mana saja. Selain itu, metode pembelajaran klasik memerlukan guru untuk menggunakan media yang lebih relevan dengan zaman, sehingga siswa lebih termotivasi untuk belajar sejarah. Media adalah media pembelajaran yang memberikan sejarah bagi Media Interaktif. Teknik mengumpulkan data, disesuaikan dengan kebutuhan para peneliti itu sendiri. Analisis survei digunakan untuk memverifikasi data yang diperlukan. Tujuan penelitian adalah: (a) membuat sejarah pengembangan media pembelajaran interaktif Media Interaktif untuk siswa kelas IX SMP Semester Ganjil, (b) menggunakan langkah-langkah pembelajaran berbasis media pembelajaran interaktif sejarah media untuk siswa kelas IX di SMP Semester Ganjil, (c) mengembangkan bahan yang digunakan dalam pengembangan sejarah menggunakan Media Interaktif untuk siswa kelas IX SMP Semester Ganjil. Hasilnya media pembelajaran sejarah bisa diterapkan dengan baik pada Sekolah Menengah Pertama Semester Ganjil.
