Abstract

Determining a concentration is one of the obligations for computer systems students because it has a direct impact on their careers and individual potential development. However, most students determine their concentration based on general perceptions without understanding their personal interests and talents, job trends, or even following their friends' choices. Therefore, this study aims to help students recognize their potential, interests, and abilities in choosing the right concentration. This study uses the Forward Chaining method, which is an expert system-based approach oriented towards factual data to draw conclusions and provide relevant recommendations. In its implementation, the system will process inputs in the form of interests, talents, and ability assessment results, then trace logical rules to determine the most suitable concentration. The final result of the research is expected to produce visual recommendations in the form of percentages, which show the level of compatibility between students' interests and talents with various concentration options. The system is expected to support a more objective, systematic, and data-driven academic decision-making process so that students can optimize their potential to the maximum.

Abstract

Website organisasi memiliki peran penting dalam mendukung transparansi, aksesibilitas, dan efektivitas penyebaran informasi pada lembaga pendidikan dan asosiasi profesi. Penelitian ini bertujuan mengembangkan website organisasi APTIKOM SUMUT menggunakan framework CodeIgniter dengan pendekatan Model View Controller (MVC) untuk menghasilkan sistem informasi yang terstruktur, mudah dikelola, dan responsif. Metode pengembangan yang digunakan adalah Software Development Life Cycle (SDLC) model Waterfall, yang meliputi tahap analisis kebutuhan, perancangan, implementasi, pengujian, serta evaluasi. Hasil pengembangan menunjukkan bahwa sistem mampu menyediakan fitur utama seperti pengelolaan agenda, pengumuman, berita, dokumentasi kegiatan, keanggotaan, serta tampilan profil organisasi. Evaluasi tampilan pada beberapa halaman menunjukkan bahwa fungsi sistem berjalan dengan baik, namun aspek antarmuka seperti konsistensi warna, hierarki visual, tipografi, dan estetika masih perlu ditingkatkan untuk memberikan pengalaman pengguna yang lebih optimal. Secara keseluruhan, website yang dikembangkan telah memenuhi kebutuhan dasar penyebaran informasi organisasi, tetapi modernisasi UI/UX direkomendasikan agar efektivitas komunikasi digital APTIKOM SUMUT dapat semakin meningkat

Abstract

The implementation of online exams differs significantly from exams supervised directly by proctors. Participants' body movements and interactions can be easily read. Even with camera monitoring, participants can still easily switch browser tabs or open applications on their devices. On the other hand, camera-based proctoring solutions can also raise invasive privacy concerns. Furthermore, device limitations can hinder someone from taking the exam due to the lack of a camera, and bandwidth limitations can result in unstable connections during the exam. Sample log activity data from test participants for log_id ranges from 44790 to 46883, while the actions consist of fullscreen_exit, context_switch, standby_log, focus_return, fullscreen_enter, and devtools_open. The results and rules of this test have scores, with each result having an average value of 1, and the rules having an average value of 1-10. In this process, experts assess each detection result using a binary scheme: a score of 1 is given if the expert system's conclusion matches the expert's decision, and a score of 0 is given if the expert system's decision does not match the expert's decision. This study proposes an expert system framework with a cameraless forward chaining method running on the Google Chrome browser (desktop and Android) as decision support. The system utilizes browser event telemetry (visibility changes, fullscreen, standby) that aligns with existing policies, such as mandatory fullscreen mode, copy/paste blocking, and question blurring when exiting fullscreen or a visibility change occurs. This can generate an audit trail that can be audited by decision makers.
