Abstract

Heart failure is a cardiovascular disease with a high mortality rate and tends to increase every year. Therefore, a method is needed that can help the process of classifying heart failure quickly and accurately. This study aims to design and implement a heart failure classification system using the K-Nearest Neighbor (K-NN) machine learning method. The dataset used consists of 918 patient data with eleven input variables and two output classes, namely patients diagnosed with heart failure and patients not diagnosed with heart failure. The research stages include data loading, dividing training data and test data, implementing the K-NN algorithm with various K values, and evaluating model performance using accuracy, precision, recall, and F1-score metrics. The test results show that variations in the K value have a significant effect on the performance of the classification model. The K value = 9 produces the best performance with an accuracy of 93.48%, a recall of 96.36%, and an F1-score of 94.64%, which indicates a good balance between precision and recall. Based on these results, the K-NN method with a value of K = 9 is recommended as the optimal configuration in the classification of heart failure disease in this study.

Abstract

Perkembangan machine learning mendorong pemanfaatan berbagai model regresi untuk melakukan prediksi data secara akurat dan efisien. Namun, perbedaan karakteristik dataset menyebabkan kinerja setiap model bervariasi, sehingga diperlukan proses benchmarking untuk menentukan model yang paling optimal. Penelitian ini bertujuan untuk membandingkan kinerja beberapa model machine learning dalam tugas prediksi data berbasis regresi tanpa melakukan pengembangan aplikasi. Model yang dievaluasi meliputi Linear Regression, Decision Tree Regression, Random Forest Regression, Support Vector Regression, dan K-Nearest Neighbor Regression. Dataset yang digunakan merupakan dataset publik dengan variabel numerik yang telah melalui tahap praproses data, meliputi pembersihan data, normalisasi, dan pembagian data latih serta data uji. Evaluasi kinerja model dilakukan menggunakan metode K-Fold Cross Validation dengan metrik Mean Absolute Error (MAE), Mean Squared Error (MSE), Root Mean Squared Error (RMSE), dan koefisien determinasi (R²). Hasil penelitian menunjukkan bahwa Random Forest Regression memberikan kinerja terbaik dengan nilai error terendah, nilai R² tertinggi, serta stabilitas model yang baik dibandingkan model lainnya. Hasil ini menunjukkan bahwa pendekatan ensemble efektif dalam meningkatkan akurasi dan kemampuan generalisasi model pada tugas prediksi data regresi.

Abstract

Artikel ini membahas tentang latar belakang, metode, dan hasil penerapan Metode Zachman dalam perancangan sistem penggalangan dana online. Metode Zachman adalah kerangka kerja yang memberikan pendekatan holistik untuk desain sistem dengan mempertimbangkan perspektif yang berbeda, seperti apa, bagaimana, di mana, siapa, kapan, dan mengapa. Dengan menerapkan metode ini, pengembang sistem dapat lebih memahami kebutuhan pengguna dan merancang sistem penggalangan dana yang lebih efektif dan efisien. Artikel tersebut membahas pentingnya mengklarifikasi kebutuhan pengguna, memilih teknologi yang paling efisien, meningkatkan efektivitas jadwal dan jadwal, serta menyediakan informasi yang lebih detail untuk meningkatkan kepercayaan pengguna. Secara keseluruhan, penggunaan Metode Zachman dapat membantu pengembang sistem membuat keputusan yang lebih baik dan menciptakan sistem penggalangan dana yang lebih efektif, efisien, dan bermanfaat bagi masyarakat. Kesimpulannya, penerapan Metode Zachman dalam perancangan sistem penggalangan dana online dapat membantu pengembang sistem membuat sistem yang memenuhi kebutuhan pengguna dan tujuan penggalangan dana secara lebih efektif. Metode ini memberikan kerangka kerja yang berguna untuk membuat keputusan yang lebih baik dan mempertimbangkan perspektif yang berbeda dalam desain sistem. Sistem yang dihasilkan dapat membantu organisasi mencapai tujuan penggalangan dananya dan memberikan manfaat yang lebih besar kepada masyarakat.

Abstract

HIV/AIDS remains a health issue that requires serious attention, especially among early adults who have high social activity. Limited knowledge about transmission and prevention, along with persistent stigma in society, makes HIV/AIDS education less effective. This study aims to design motion graphic-based educational media so that HIV/AIDS prevention information becomes more engaging, easier to understand, and suitable for the characteristics of early adults. The methods used include a literature review, observation, and audience needs analysis, followed by concept development, storyboard creation, visual design, and production. The result is an educational motion graphic video that explains HIV/AIDS, modes of transmission, prevention strategies, and encourages healthy behavior and non-discriminatory attitudes toward people living with HIV/AIDS. This media is expected to improve early adults’ knowledge, awareness, and positive attitudes toward HIV/AIDS prevention.

Abstract

Villa Nomada, as an accommodation in Kuta, Central Lombok, is experiencing internet network instability due to uneven and uncontrolled bandwidth distribution, which disrupts user comfort, especially for foreign guests who require an optimal connection. The solution implemented is bandwidth management using the Hierarchical Token Bucket (HTB) method to allocate bandwidth fairly and efficiently. This research contributes to improving quality of service (QoS) by optimizing network performance through HTB. The method used is HTB configuration to allocate bandwidth based on user categories (VIP, Regular, and Office). Network performance was evaluated before and after implementation to measure improvements in speed and stability. The research results showed that HTB successfully distributed bandwidth evenly, with VIP users receiving priority, while regular and office users obtained stable connections without interruptions. Network efficiency improved, reducing congestion and increasing user satisfaction. We rated the HTB method as “Good” for optimizing network performance. In conclusion, the implementation of HTB successfully addressed the bandwidth management issues at Villa Nomada, ensuring fair distribution and optimal network performance for all users.
