Abstract

Purpose: Stroke is a critical global health issue requiring early and accurate prediction to mitigate severe outcomes. This study aims to compare the performance of the K-Nearest Neighbors (KNN) and Naive Bayes algorithms in predicting stroke disease, addressing the challenge of imbalanced datasets and improving prediction accuracy for better clinical decision-making.Methods/Study design/approach: The research followed the CRISP-DM model, utilizing a dataset of 5,110 patient records with 12 attributes from Kaggle. Data preprocessing included handling missing values and normalization. The KNN and Naive Bayes algorithms were implemented using RapidMiner, with performance evaluated through cross-validation, confusion matrices, and ROC-AUC curves.Result/Findings: The KNN algorithm achieved an accuracy of 94.50%, but exhibited low precision (7.89%) and recall (1.20%) for stroke-positive cases due to dataset imbalance. Naive Bayes yielded an accuracy of 88.83% with an AUC of 0.767, demonstrating better probability modeling but similar challenges in minority class detection. Both algorithms highlighted the impact of data imbalance on predictive performance.Novelty/Originality/Value: This study provides a comparative analysis of KNN and Naive Bayes for stroke prediction, emphasizing the need for data balancing and optimization techniques. The findings underscore the potential of these algorithms in healthcare applications while suggesting future improvements through ensemble methods or alternative algorithms like Random Forest.

Abstract

Penelitian ini bertujuan untuk menganalisis peran desain kemasan kreatif dalam meningkatkan minat beli produk minuman kekinian pada Generasi Z. Desain kemasan tidak hanya berfungsi sebagai pelindung produk, tetapi juga sebagai alat komunikasi pemasaran yang mampu membentuk persepsi, menarik perhatian, dan memengaruhi keputusan konsumen. Generasi Z dikenal sebagai kelompok konsumen yang memiliki ketertarikan tinggi terhadap aspek visual, inovasi, dan identitas merek, sehingga desain kemasan menjadi faktor strategis dalam menarik minat beli mereka. Penelitian ini menggunakan pendekatan kuantitatif dengan metode survei terhadap responden Generasi Z yang pernah mengonsumsi produk minuman kekinian. Data dianalisis menggunakan teknik analisis statistik untuk menguji pengaruh desain kemasan kreatif terhadap minat beli. Hasil penelitian menunjukkan bahwa desain kemasan kreatif berperan signifikan dalam meningkatkan minat beli produk minuman kekinian pada Generasi Z. Temuan ini menegaskan bahwa elemen visual, keunikan desain, dan kesesuaian kemasan dengan karakter konsumen muda menjadi faktor penting dalam strategi pemasaran produk. Oleh karena itu, pelaku usaha di industri minuman kekinian disarankan untuk mengembangkan desain kemasan yang inovatif dan relevan dengan preferensi Generasi Z guna meningkatkan daya saing produk di pasar.

Abstract

This research purposed to investigate the effect of  integrated science model and its implementation in learning by Unity of Science in Basic Biology courses to improve students' critical thinking. This method research is a quasi-experimental with experimental design posttest only control group design. The population was all students of the first semester Biology, 2015/2016 academic year with consists  of  two classes.  Samples were taken with a simple random sampling technique. The data was collected using an open essay tests and observation of critical thinking skills. Data were analyzed with descriptive analysis and MANOVA test. The results showed as follows: (1) There are differences between the understanding of basic biology concepts students learn to use the integrated science model of with students who learn to use the direct teaching model (F = 7.783; p <0.05), (2) there are differences in thinking skills critical significantly between students learning with integrated science model and its implementation in Unity of science learning with students who learn to use the direct teaching model (F = 11.11, p <0.05).
