Abstract

Choosing the right university major is an important decision for students, as delays or incorrect choices can harm their future careers and cause problems for academic departments. High dropout rates, which are frequently the result of poorly informed decisions, can be a considerable burden on faculty. This project aims to address these challenges by creating a recommendation system that provides individualized counsel to students based on their psychological profiles. A quantitative method was used, with questionnaires distributed to a large number of students. To verify the data's authenticity, replies were sought from students who were pleased with their selected majors rather than those who regretted their choices. The collected data formed the basis for a hybrid recommendation system that integrated Content-based Filtering and Collaborative Filtering methods. The system was then compared against standalone implementations of each filtering method to determine its usefulness in increasing suggestion accuracy. The results showed that the Hybrid Filtering strategy obtained a recommendation accuracy of 84.29%, outperforming Content-based  Filtering at 81.43% and Collaborative Filtering at 78.57%. The proposed model is easy to implement in a school or a university, as long as the required data is available. Thus, the model can help a school or university to reduce dropout rates and boost academic outcomes.

Abstract

Dalam era digital yang semakin berkembang, teknologi Internet of Things (IoT) memiliki peran krusial dalam mendorong efisiensi dan inovasi. Namun, pemahaman siswa SMA Sint Louis tentang IoT masih terbatas, yang dapat menghambat kesiapan mereka dalam menghadapi tantangan teknologi masa depan. Untuk mengatasi hal ini, sebuah kegiatan pengabdian masyarakat dilaksanakan dengan tujuan memperkenalkan konsep dan aplikasi IoT kepada siswa. Metode yang digunakan meliputi penyampaian materi teoretis dan demonstrasi perangkat IoT, yang dilakukan selama dua hari. Evaluasi melalui kuesioner menunjukkan peningkatan signifikan dalam pemahaman siswa tentang IoT, dari 51% sebelum pelatihan menjadi 79% setelah pelatihan. Peningkatan ini mencakup pemahaman konseptual, kemampuan konfigurasi perangkat, dan keterampilan pemecahan masalah. Kegiatan ini diharapkan dapat memperluas wawasan siswa tentang IoT serta mempersiapkan mereka untuk menghadapi perkembangan teknologi di masa depan.
