Abstract

Heart disease, particularly heart attacks, is a leading cause of death worldwide, highlighting the importance of early detection and risk prediction. This study develops and evaluates machine learning models to predict heart attack risk using seven health-related attributes: age, marital status, gender, body weight category, cholesterol level, participation in stress management training, and stress level. The dataset, processed with the Orange Data Mining platform, was divided into training (66%) and testing (34%) sets. Two supervised algorithms, Decision Tree and K-Nearest Neighbors (K-NN), were implemented without extensive hyperparameter tuning. Model performance was evaluated using accuracy, precision, recall, and F1 score. The Decision Tree achieved the best results with 84.78% accuracy, 88.52% precision, 79.41% recall, and 83.72% F1 score, indicating its effectiveness in identifying at-risk individuals. Key predictors included age, stress level, and cholesterol, aligning with established medical findings. While the results are promising, limitations include a small dataset and limited algorithm scope. Future research should expand the dataset, include additional clinical features, and explore advanced algorithms to improve accuracy and reduce false negatives, enhancing applicability in preventive healthcare.

Abstract

None of the several theories that underpin the assessment of IT adoption characterizes the process as dynamically as the Means of Engagement theory does. User satisfaction is a key factor in influencing the success of ERP implementation as well as the adoption of the ERP system by the user. Therefore, it is necessary to identify the factors affecting user satisfaction of the ERP system as well as the relationship between customer satisfaction and user involvement. This research aims to develop a concept or model of Means of Engagement (MOE) on relationship domain in particular for satisfaction factor with the research object of PT Glico Indonesia. The research uses SEM-PLS analysis method using the SmartPLS 4 application to construct and test a structural equation model that reflects the relationship between the variables investigated in the research. The evaluation results showed that the five SERVQUAL dimensions studied did not have a significant impact on user satisfaction while customer satisfaction had a significant positive impact on engagement. The results of this research, namely the development of the Means of Engagement model, are expected to be the basis for PT Glico Indonesia to design strategies that can improve and maintain the adoption of ERP system users based on the level of the means of engagement model.

Abstract

In the contemporary landscape, technology holds pivotal significance across diverse domains, including academia and industry. The Faculty of Industrial Engineering at Telkom University faces challenges in optimizing the value derived from its IT investments to meet evolving market demands. To address this, IT governance methodologies are essential, ensuring effective and secure IT utilization aligned with strategic objectives. This study investigates and evaluates the IT delivery value process at the Faculty of Industrial Engineering, Telkom University, using the COBIT 2019 Domain APO04 framework and LAM INFOKOM standards. Data collection involved primary interviews and secondary document analysis. The analysis revealed gaps in assessing emerging technologies and recommending further initiatives. Recommendations span people, process, and technology aspects, aiming to enhance technology evaluation procedures and documentation. This study provides insights into effectively leveraging IT to achieve the Faculty's objectives and enhance decision-making quality.
