Abstract

Selecting a faculty that aligns with students’ interests and talents is a strategic step in determining the success of higher education and future career paths. However, most vocational high school (SMK) students still face difficulties in identifying the most suitable faculty due to the lack of data-driven analysis. This study implements the C4.5 classification algorithm within data mining techniques to build an automatic and measurable faculty recommendation system. The dataset consists of attributes such as SMK major, interest level, aptitude test results, academic grade average, and gender, with the output being the recommended faculty. The C4.5 algorithm was chosen for its ability to generate a transparent and interpretable decision tree, which helps both guidance counselors and students understand the rationale behind the recommendations. The experimental results show that the constructed classification model achieved an accuracy rate of 88%, based on cross-validation testing using data from 12th-grade students. The implementation of this system is expected to serve as an objective tool in the faculty selection process and to promote a data-driven decision-making approach in secondary education environments.

Abstract

The rapid advancement of information technology requires teachers to possess adequate digital skills and understanding to support the learning process. A website serves as an essential digital medium that can be utilized for providing information, learning materials, activity documentation, and facilitating communication among teachers, students, and the school. This study aims to develop and manage a school website as a means to enhance information technology knowledge for teachers at SMP Bina Bangsa Mandiri Cikeas, Bogor Regency. The research employed a system development approach, including needs analysis, design, implementation, and evaluation of website usage by teachers. The results indicate that the developed website provides ease of access in managing school information, preparing digital learning content, and improving teachers’ digital literacy. Moreover, the website serves as a collaborative platform that supports teachers in sharing materials and teaching innovations. Therefore, developing and managing a website effectively contributes to enhancing information technology competence among junior high school teachers.
