ing, and a combination of both in a movie recommendation system. The method used in this study involves retrieving movie details from the TMDB API and ratings from the MovieLens 32M Dataset (2010-2023). Each model's performance is evaluated using evaluation metrics such as RMSE and MAE. The results of this study indicate that Neural Collaborative Filtering achieves the best prediction performance (RMSE = 0.785423, MAE = 0.581262), followed by the hybrid model (RMSE = 0.800863, MAE = 0.660872), while Content-Based Filtering produces low performance and limits the capabilities of the hybrid model. In conclusion, these findings highlight the superiority of latent feature-based models such as NCF that learn directly from user interaction patterns over content-based approaches in the context of modern recommendation systems.

For transacting on the internet, reliable data security is needed to maintain the security of user data from internet crimes (cybercrime). For cryptography learning to produce students who understand cryptography in-depth, this learning is carried out independently. One of the lessons to improve independent skills is a project approach. With project-based learning, students will be actively involved in completing projects given by the lecturer. To facilitate interaction and monitor projects completed by students, an LMS (Learning Management System) was created. The lecturer will later upload the student projects through the LMS, and if the student wants to work on the project, they can download it from the LMS.
