Abstract

Kementerian Pendidikan dan Kebudayaan membuat kebijakan baru dibidang pendidikan yaitu Merdeka Belajar Kampus Merdeka (MBKM) dengan dilandasi oleh Peraturan Menteri Pendidikan dan Kebudayaan Republik Indonesia No.3 Tahun 2020 tentang Standar Nasional Pendidikan Tinggi. Model penilaian yang berbeda dari sebelumnya mengakibatkan pekerjaan menjadi lama, dan belum tersedianya sistem informasi dan sistem penilian otomatis untuk mendukung kegiatan belajar terutama pada program Studi Proyek Independen. Task Centered System Design (TCSD) merupakan sebuah metode yang digunakan untuk merancang user interface dari sebuah sistem. Perancangan sistem menggunakan metode waterfall sebagai alur pengerjaan dari aplikasi kemudian mnggunakan TCSD sebagai perancangan user interface. Penelitian ini menghasilkan sebuah aplikasi sistem penilaian yang dapat membantu dalam melaksanakan kurikulum MBKM. Aplikasi akan melalui dua pengujian yaitu pengujian blackbox dan System Usability Scale (SUS) dengan nilai minimal SUS yang harus dicapai adalah 80.

Abstract

Introduction: The honors class program aims to group outstanding students, but an objective data-based classification system is not yet available. This can result in high-potential students going undetected due to the selection process relying on self-registration and causing a lack of student interest. Method: This research uses the Support Vector Machine (SVM) algorithm to classify the eligibility of students to participate in the honors program based on academic and non-academic data. The dataset consists of 453 entries with an imbalanced class distribution, which was then balanced using the SMOTE technique. The model was trained using GridSearchCV to find the optimal parameters and compared with four types of SVM kernels: linear, polynomial, sigmoid, and radial basis function (RBF). Result: The RBF kernel achieved the best performance with an accuracy of 84%, precision of 0.77, recall of 0.84, and an F1-score of 0.79. However, it was found that the precision in the minority class (high-achieving students) is still lower than in the majority class. Conclusion: The SVM model, particularly with the RBF kernel, has proven effective in automating the classification of students for the honors program. However, further improvements are needed to enhance performance on the minority class to make the selection system fairer and more accurate

Abstract

Viruses remain a major concern in global public health due to their potential to cause outbreaks, epidemics, and pandemics. The rapid organization and analysis of virus-related data are important for supporting computational virology, health informatics, and pandemic preparedness. This study proposes an unsupervised machine learning approach to cluster viruses based on taxonomic and genomic characteristics. The dataset consisted of 70 virus records with attributes including family, genus, genome type, strand type, and envelope status. Since the dataset did not contain predefined epidemiological labels or risk categories, the analysis was designed as an exploratory clustering task rather than a supervised prediction task. Data preprocessing was performed by removing duplicates, handling missing values, standardizing categorical attributes, and transforming selected features using One-Hot Encoding. Three clustering algorithms were evaluated, namely K-Means, Agglomerative Clustering, and DBSCAN. The clustering performance was assessed using Silhouette Score, Davies-Bouldin Index, and Calinski-Harabasz Score, while Principal Component Analysis was applied for two-dimensional visualization. The results showed that K-Means with 10 clusters achieved a Silhouette Score of 0.7725 and a Davies-Bouldin Index of 0.8186. Agglomerative Clustering obtained the highest Silhouette Score of 0.7754, while DBSCAN produced fewer clusters with lower overall performance. Several biologically meaningful groups were identified, including clusters representing Flaviviridae, Coronaviridae, Herpesviridae, Poxviridae, and enveloped RNA viruses. However, a large proportion of records contained unknown values, which influenced the formation of a dominant incomplete-data cluster. These findings indicate that taxonomic and genomic features can support machine learning-based virus grouping, although data completeness remains a critical factor. This study provides an initial computational framework for AI-driven viral data exploration and may serve as a foundation for future viral risk stratification using enriched epidemiological and clinical features.
