Abstract

Queue irregularities are a common problem with photocopying services, particularly with student assignment printing. Because there is no clear system for managing the order in which documents are printed, students often have to wait long periods. This can lead to dissatisfaction and confusion. The purpose of this research is to create an interactive web application capable of managing routine print queues using a linked list-based queue structure. A queue system based on the FIFO (First In First Out) principle was created. This allows each student to enter their identity, the files to be printed, and any special notes about their printing needs. The system then displays a real-time queue list, allowing the photocopy operator to download the files in the correct order.

Abstract

Data imbalance represents a primary challenge in clustering analysis, particularly in datasets with highly disproportionate class distributions such as the Credit Card Fraud Detection dataset from Kaggle. This study aims to evaluate and compare the performance of the Gaussian Mixture Model (GMM) and K-Means algorithms under such conditions through a systematic literature review of nine prior studies. Clustering quality is evaluated using three internal validation metrics: Silhouette Score, Davies-Bouldin Index (DBI), and Calinski-Harabasz Index (CHI). The findings indicate that GMM consistently produces more stable and flexible clusters in data with overlapping distributions, as its probabilistic approach through the Expectation-Maximization (EM) algorithm allows each data point to hold multiple cluster membership probabilities. In contrast, K-Means produces sharper cluster boundaries with lower computational complexity, yet remains sensitive to outliers and the spherical distribution assumption frequently unmet in imbalanced data. The dominance of the majority class risks distorting K-Means centroids, resulting in suboptimal detection of fraudulent transactions, whereas GMM proves more adaptive for this scenario despite its higher computational cost.

Abstract

The proliferation of campus events across various student organizations has led to fragmented information distribution, making it difficult for students to discover and participate in relevant activities. This study presents the design and development of CampusVents, a web-based platform that integrates three core functions: event aggregation from multiple student organizations, integrated event management, and a user interest-based event recommendation system. The platform was developed using the Laravel 10 framework, PHP 8.2, MySQL 8.0, and Bootstrap 5, following the waterfall software development methodology. System testing was conducted through User Acceptance Testing (UAT) involving 50 respondents using a Likert-scale questionnaire covering aspects of usability, functionality, performance, aesthetics, and acceptability. The overall average score reached 4.37 out of 5.00, categorized as “Good,” with the usability and performance aspects obtaining the highest scores (4.40). The recommendation feature employing an interest-based filtering approach was positively received, with 52% of respondents indicating willingness to adopt the platform if officially deployed on campus. These findings confirm that CampusVents effectively addresses the problem of fragmented campus event information and demonstrates significant potential for adoption in academic environments.

Abstract

Network traffic monitoring is a critical aspect of managing information technology infrastructure, especially as the growing number of devices and users increases system complexity. Conventional command-line-based approaches are no longer sufficient, as they fail to provide real-time visibility, centralized data, or comprehensive metrics. This research proposes a monitoring system utilizing Grafana and Prometheus—both open-source platforms—along with Node Exporter to collect device performance metrics. The Network Development Life Cycle (NDLC) methodology was employed, encompassing analysis, design, and prototype simulation phases. The system provides real-time visualization of metrics such as bandwidth usage, CPU and memory utilization, and network status through an interactive dashboard. Black-box testing confirmed that all features function according to the defined scenarios. Ultimately, the system proves to be efficient and scalable, enabling administrators to monitor and analyze network conditions more rapidly and accurately than manual methods.
