Abstract

This study aims to improve the performance of attack detection on the Bot-IoT dataset that faces class imbalance. The method used involves developing a feature selection model based on the Pearson correlation coefficient between features, with an adaptive threshold applied. The datasets used consist of two types: D1, with the 10 best features, and D2, with all features. The oversampling technique is applied to the minority class, followed by calculating feature correlations to determine the best feature using a threshold based on the average of the highest and lowest correlations. The feature selection process is carried out iteratively, with performance testing across several machine learning algorithms, including KNN, Random Forest, Logistic Regression, and SVM. The results show that the proposed feature selection method can improve the performance of the minority class without sacrificing the majority class's performance. On the D1 dataset, the Random Forest algorithm achieved 96% accuracy, while KNN achieved 93%. On the D2 dataset, KNN achieved balanced performance, with average precision, recall, and F1-score of 0.99 for both classes, while Random Forest achieved lower results on the minority class. The implications of this study indicate that correlation-based feature selection can improve attack detection performance on datasets with high class imbalance, and it can be implemented in future studies to address similar problems in IoT-based intrusion detection systems.

Abstract

The Ministry of Education and Culture is implementing online learning as a learning method of choice during this pandemic. The obstacle that is often faced in terms of teaching media is the inadequate specification of a computer or laptop for online learning, especially in terms of operating systems that do not match the specifications of a computer or laptop. The objective of this community service is to increase the ability of educators and the general public to optimize the Windows 10 operating system on a computer or laptop with minimal specifications. This community service was carried out by organize an online training using Zoom. The result shows that online training participants are able to optimize Windows 10 on their respective hardware. This shows that the participants already understand how to optimize Windows 10 in the minimum computer or laptop specifications.
