Abstract

This research aims to produce an optimal course schedule at STMIK Mulia Darma, with the aim of reducing the number of conflicting courses, equalizing the student burden, and maximizing the use of classrooms. The optimization process is carried out through determining the course schedule using a genetic algorithm. Genetic algorithms were chosen because of their ability to solve large-scale and complex problems, making them suitable for handling complex course scheduling problems that involve many variables and constraints. It is hoped that the results of this study will produce an optimal course schedule, taking into account course clashes, student loads, and classroom use efficiency. After research, the optimal course schedule was obtained.

Abstract

Oral diseases such as stomatitis, gingivitis, and candidiasis are often undetected at an early stage due to limited public knowledge and restricted access to healthcare services, leading to delays in treatment. This study aims to develop an Android-based expert system for diagnosing oral diseases using a hybrid approach that combines the Naïve Bayes and Decision Tree algorithms. The Naïve Bayes method is applied to calculate the probability of symptoms associated with potential diseases, while the Decision Tree generates diagnostic rules that are more transparent and interpretable. The research stages include a literature review, data collection and validation of disease symptoms from medical experts, development of the hybrid model, implementation into an Android application, and system testing using cross-validation and a confusion matrix. The expected outcomes include a prototype Android application for oral disease diagnosis with a minimum accuracy of 85%, a scientific article published in a nationally accredited journal indexed in Sinta, and additional outputs such as copyright registration of the application and publication of a book. This study is expected to improve public access to early diagnosis of oral diseases, support early detection, and contribute to the advancement of digital health systems based on artificial intelligence in Indonesia.
