Abstract

Abstrak Pemerintah Indonesia sedang mengembangkan teknologi informasi dan komunikasi untuk memberikan pelayanan publik kepada masyarakat, salah satunya dengan mengeluarkan pedoman Sistem Pemerintahan Berbasis Elektronik (SPBE). Pemerintah Daerah di salah satu kabupaten telah menyikapi tata kepemerintahan yang baik untuk meningkatkan kesejahteraan masyarakat yang dibangun dengan dasar komunikasi yang baik antara pemerintah dan masyarakat. Berdasarkan hasil evaluasi SPBE pada tahun 2019, salah satu kabupaten di Indonesia telah mencapai skor indeks SPBE yaitu 2.88 dengan predikat “Baik”. Penelitian ini dilakukan dengan tujuan menganalisis aspek yang memiliki kontribusi paling rendah pada evaluasi SPBE untuk salah satu kabupaten di Indonesia. Aspek Tata Kelola Teknologi Informasi dan Komunikasi memiliki tiga indikator untuk dijadikan penilaian. Evaluasi yang dilakukan menghasilkan saran dan rekomendasi pada ketiga indikator untuk dijadikan pertimbangan perbaikan pelaksanaan SPBE di Pemerintah Daerah pada sebuah kabupaten Indonesia. Abstract The Indonesian government is developing information and communication technology to provide public services to the community. Which one of them is issuing guidelines for the Electronic-Based Government System (SPBE). The Regional Government in one of the districts has addressed good governance to improve the welfare of the community which was built based on good communication between the government and the community. Based on the results of the SPBE evaluation in 2019, one of the districts in Indonesia has achieved an SPBE index score of 2.88 with "Good" predicate. This research was conducted to analyze the aspects that have the lowest contribution to the evaluation of SPBE for one of the districts in Indonesia. Aspects of Information and Communication Technology Governance has three indicators that are used as an assessment. The evaluation carried out the results in suggestions and recommendations on the three indicators to be considered for improving the implementation of SPBE in the local government of an Indonesian district.

Abstract

This study presents a comprehensive evaluation of AdaBoost and Random Forest Classifier algorithms in the classification of eye diseases, focusing on a challenging scenario involving an imbalanced dataset. Eye diseases, particularly Cataract, Diabetic Retinopathy, Glaucoma, and Normal eye conditions, pose significant diagnostic challenges, and the advent of machine learning offers promising avenues for enhancing diagnostic accuracy. Our research utilizes a dataset preprocessed with Canny edge detection for image segmentation and Hu Moments for feature extraction, providing a robust foundation for the comparative analysis. The performance of the algorithms is assessed using a 5-fold cross-validation approach, with accuracy, precision, recall, and F1-score as the key metrics. The results indicate that the Random Forest Classifier outperforms AdaBoost across these metrics, albeit with moderate overall performance. This finding underscores the potential and limitations of using advanced machine learning techniques for medical image analysis, particularly in the context of imbalanced datasets. The study contributes to the field by providing insights into the effectiveness of different machine learning algorithms in handling the complexities of medical image classification. For future research, it recommends exploring a diverse range of image processing techniques, delving into other sophisticated machine learning models, and extending the study to encompass a wider array of eye diseases. These findings have practical implications in guiding the selection of machine learning tools for medical diagnostics and highlight the need for continuous improvement in automated systems for enhanced patient care.

Abstract

Cardiovascular disease (CVD) remains one of the leading causes of mortality globally, emphasizing the need for early detection and effective risk stratification. With the increasing availability of clinical and lifestyle-related health data, machine learning (ML) has become a powerful tool to support data-driven diagnosis and decision-making in healthcare. This study aims to develop and evaluate multiple supervised ML models to predict the presence of cardiovascular disease based on non-invasive features obtained from routine medical checkups. The dataset, comprising 69,301 individual records, includes variables such as age, gender, blood pressure, cholesterol, glucose levels, body measurements, and lifestyle habits. Following comprehensive data cleaning and feature engineering such as the derivation of BMI, Mean Arterial Pressure (MAP), and Pulse Pressure four classifiers were applied: Logistic Regression, Random Forest, Gradient Boosting, and Support Vector Machine (SVM). Model performance was evaluated using metrics including accuracy, precision, recall, F1-score, and ROC-AUC. Among all models tested, the Gradient Boosting Classifier achieved the highest performance, with a ROC-AUC score of 0.8060 and a balanced precision-recall tradeoff, indicating strong discriminatory power. Visualizations such as ROC curves and confusion matrices confirmed the superior capability of Gradient Boosting in differentiating between patients with and without CVD. These findings demonstrate the viability of ML-driven risk assessment models as decision-support tools in clinical settings, potentially aiding in earlier diagnosis and more personalized intervention strategies.
