Abstract

Heart failure is one of the leading causes of death in the world that requires an accurate and efficient prediction system to support clinical decision making. This study aims to develop a prediction model for the risk of death in patients with heart failure by optimizing feature selection using the Mutual Information (MI) approach. The main problem raised is the high complexity of clinical data with many features that are not always relevant, which can reduce the accuracy and efficiency of predictive models. The method proposed in this study involves MI-based feature selection to identify the most informative features against the target variable (patient mortality), which are then used to train various machine learning algorithms such as Random Forest, Gradient Boosting, XGBoost, and Logistic Regression. The hyperparameter tuning process is performed to optimize the performance of each model. The test results show that the Random Forest model that has been tuned using five selected features managed to achieve an accuracy of 0.99 and F1-score of 0.99, outperforming other models in terms of balance between accuracy and generalization. The results show that Mutual Information is effective in simplifying model complexity without compromising prediction performance.

Abstract

The radio frequency spectrum is a limited natural resource that is crucial in supporting various communication sectors. However, violations of frequency spectrum usage, such as unauthorized usage or non-compliance with technical parameters, frequently occur in the East Nusa Tenggara region. Monitoring conducted by the Radio Frequency Spectrum Monitoring Center Class I Kupang faces challenges due to manual record-keeping and scattered data, which hinder efficient evaluation and management of violations. This study aims to develop a web-based information system capable of monitoring and recording the history of radio frequency spectrum violations in a centralized and real-time manner. The system is also designed to facilitate easier access to information and management of violation data. Data collection methods used in this research include literature studies, observation, and interviews. Meanwhile, the software development method applied is the Waterfall model, which includes the stages of analysis, design, coding, testing, and maintenance. The result of this research is an information system that provides centralized violation history data to support more effective radio frequency spectrum management in the East Nusa Tenggara region

Abstract

The use of information technology in visa services can provide convenience; however, it also gives rise to various problems, as experienced at the South Jakarta Immigration Office, including ineffective mechanisms, technical disruptions, and the potential for identity falsification. The research problems addressed in this study concern how information technology is used in visa services at the South Jakarta Immigration Office based on Law Number 63 of 2024 in conjunction with Law Number 6 of 2011, as well as the obstacles encountered in the use of information technology in visa services at the South Jakarta Immigration Office. This study employs a normative research method with a descriptive approach. Data were collected through literature studies and interviews and analyzed qualitatively. The results indicate that visa services at the South Jakarta Immigration Office have implemented information technology through an online-based e-visa system as regulated in Law Number 63 of 2024 in conjunction with Law Number 6 of 2011. All visa application processes are conducted digitally and in real time. The obstacles encountered include internal constraints, such as discrepancies in uploaded data, system validation failures, and technical disruptions, as well as external constraints, including the risk of cyberattacks, potential data breaches, and low levels of users’ digital literacy. These obstacles have been addressed through improvements in technological infrastructure, strengthening of digital security, and the provision of online guidelines to ensure the continuity of optimal services. The Government is expected to enhance continuous evaluation of the electronic visa system.

Abstract

Universitas Nahdlatul Ulama (UNU) Yogyakarta has long depended on static 2D photographs and scattered social media content to convey campus conditions — a method that consistently falls short of giving prospective students any real spatial understanding of the campus environment. For students outside Yogyakarta, this means making enrollment decisions based on incomplete visual fragments. This study addresses that gap by designing and building a web-based 360° Virtual Tour system using the Prototyping development method. The system adopts a decoupled architecture: Django REST Framework handles backend data operations, while Next.js — paired with the React Photo Sphere Viewer library — drives the panoramic front-end display. Black Box functional testing confirmed that all eight tested features operated without error. User Acceptance Testing (UAT) conducted with 66 respondents produced a feasibility score of 83.0%, classified as "Very Feasible." The highest-rated indicator was Real Campus Representation at 4.44 out of 5.00, confirming that users found the system's depiction of campus space genuinely accurate. The system offers a self-managed, cost-conscious alternative to vendor-dependent tour platforms, with clear implications for how smaller institutions can reclaim control over their own digital presence.

Abstract

In addition to analyzing the impact of governance and human resource competencies on the effective deployment of information technologies for local government, this study also looks at organizational Inertia as a moderating factor that may amplify or diminish these effects. This study offers novelty by positioning Organizational Inertia as a moderating variable, a factor that has received limited attention in prior SIPD implementation studies. Saturated sampling techniques were employed to collect primary data from 76 employees of the Central Sulawesi Provincial Financial and Asset Management Agency involved in the implementation of the Local Government Information System. The study took a quantitative approach. WarpPLS 8.0 was used to analyze the data using Structural Equation Modeling–Partial Least Square (SEM-PLS). The findings demonstrated that there was no discernible impact of human resource competency. On the contrary, the success of system adoption is significantly impacted by Governance. Organizational Inertia, a moderating variable, strengthened the influence between independent and dependent variables. These results demonstrate that improving Governance is essential to the effective deployment of information technologies.
