Kegagalan jantung (Heart Failure) merupakan salah satu penyebab utama kematian dan morbiditas secara global, dengan lebih dari 26 juta orang terdampak di seluruh dunia. Deteksi dini kegagalan jantung sangat penting untuk mencegah komplikasi yang lebih serius, namun diagnosis sering kali sulit dilakukan karena gejala yang tidak spesifik. Pembelajaran mesin (machine learning) telah banyak digunakan untuk membantu prediksi risiko kegagalan jantung melalui analisis data medis. Berbagai algoritma klasifikasi telah diimplementasikan dalam berbagai penelitian sebalumnya, namun belum ada konsensus mengenai algoritma terbaik. Penelitian ini bertujuan untuk melakukan komparasi performa beberapa algoritma klasifikasi dalam memprediksi gagal jantung, menggunakan dataset Heart Failure Prediction dari Kaggle. Algoritma yang diuji termasuk Logistic Regression, K-Nearest Neighbors (KNN), Decision Tree, Random Forest, GaussianNB, dan LightGBM. Hasil menunjukkan bahwa algoritma Random Forest memberikan performa terbaik dengan akurasi 95 persen, sedangkan algoritma KNN menunjukkan akurasi terendah sebesar 76 persen. Penelitian ini diharapkan dapat berkontribusi dalam pengembangan sistem pendukung keputusan klinis yang lebih baik untuk prediksi kegagalan jantung.

Abstract. This study presents a web-based system for identifying traditional herbal leaves using K-Nearest Neighbors (KNN) and image processing techniques focused on analyzing leaf shape and color. The dataset used consists of images of various types of herbal leaves, providing a basis for classification and medicinal benefit information retrieval. The system was tested with multiple leaf samples to assess accuracy, speed, and effectiveness in identifying leaf types based on visual characteristics. Results show that the system can recognize different types of herbal leaves and display information on their medicinal properties in a user-friendly interface..

Because a brand allows it to influence consumers in making purchases and carry the good name of companies that produce goods or services. This study aims to determine and analyze the relationship between positioning and brand image on purchasing decisions. The method used is quantitative. Subjects in this study involved 30 people. The data collection method uses three scales, customer decision scale, positioning scale, and brand image scale. Research sampling using purposive sampling. The data were analyzed using the regression model and the model was gradually filled in with the help of the SPSS for Windows Statistical Package for Social Sciences program.

Communication between devices is an important aspect when developing an Arduino-based system. The three communication protocols commonly used with Arduino are I2C (Inter-Integrated Circuit), SPI (Serial Peripheral Interface), and UART (Universal Asynchronous Receiver/Transmitter). Each of these protocols has unique characteristics that make them suitable for different applications. These three communication protocols provide flexible options when developing systems that communicate with sensors, actuators, or other modules on the Arduino platform. Selecting the appropriate protocol depends on specific needs, such as speed, number of connected devices, and system complexity.
