Abstract

Aplikasi pencocokan sidik jari ini dirancang dengan menerapkan metode Ekstraksi Minusi menggunakan Matlab 7.1. Pengujian dilakukan dengan menggunakan citra sidik jari yang berasal dari sumber yang sama pada kondisi jarak kecocokan 10, 20, 30 piksel dan pada sudut kecocokan 1/3 , 1/4 , 1/5  serta menggunakan citra sidik jari yang berasal dari sumber yang berbeda. Hasil penelitan menunjukkan persentasi nilai kecocokan pada jarak 20 piksel lebih besar daripada jarak 10 piksel dan persentasi nilai kecocokan pada jarak 30 piksel lebih besar daripada jarak 20 piksel serta persentasi nilai kecocokan untuk sumber sidik jari yang sama lebih besar dari sumber yang berbeda. Kata kunci : sidik jari, Ekstraksi Minusi, pencocokan.

Abstract

Distributed Denial of Service (DDoS) attacks represent a significant danger in network security because they can lead to extensive service interruptions. With these attacks increasingly mirroring regular traffic, smart and effective detection systems are essential. This research seeks to assess the efficacy of the Support Vector Machine (SVM) classification algorithm in identifying DDoS attacks in network traffic. The data utilized is CICIDS2017, focusing on the subset Friday-WorkingHours-Afternoon-DDos.pcap_ISCX.csv, which contains both legitimate traffic and DDoS attacks like DoS-Hulk, DoS-GoldenEye, and DDoS. The preprocessing stage included eliminating duplicates and null entries, label binary encoding, normalization through Min-Max Scaler, and feature selection applying the Chi-Square technique. The data was divided into 80% for training and 20% for testing purposes. The Radial Basis Function (RBF) kernel was utilized to train the SVM model, and hyperparameter optimization was performed with GridSearchCV. The evaluation of the model's performance was conducted through accuracy, precision, recall, F1-score, confusion matrix, and visual representations including ROC and Precision-Recall Curves. The findings indicate that prior to tuning, the model reached an accuracy of 97%, which increased to 99% post-tuning, accompanied by an F1-score of 0.99. This shows that the SVM algorithm, when paired with appropriate preprocessing and optimization, is very efficient in identifying DDoS attacks within network traffic.

Abstract

In today's modern world and the high level of competition, everyone is expected not only to have a high level of education but also to require special skills or what we usually call "skills." One of the "skills" currently needed is English language skills. The role of English is necessary both in mastering communication technology and interacting directly. As a means of global communication, English must be mastered actively, both spoken and written. This teaching activity focuses on increasing interest in learning English among children and teenagers in Nagari Lalang Panjang. The goal is to increase interest in learning and improve English language skills (soft skills). Some of the methods PKM students use are question and answer and discussion methods to identify knowledge and supporting technology. The lecture method is used during learning and theoretical understanding of English. The results achieved are: 1. They understand the importance of learning English as children. 2. Children will become familiar with English. 3. many children and teenagers are not interested in the importance of learning English.

Abstract

English is one of the compulsory subjects that must be taught by every school at all levels, from primary school to university. But sometimes, students find it difficult to understand the material given by the teacher. In addition, the provision of monotonous material may feel boring for students, causing a lack of motivation to learn English. In addition, for elementary students, learning should use teaching methods that involve students. To overcome these problems, Fun English Learning is structured as one of the recommended programs so that teachers can increase the motivation and awareness of elementary students in learning English. Through fun learning methods such as the use of games in learning, students can more quickly absorb material and increase their interest. In addition, students do not get bored when learning English. On the contrary, students feel happy and excited when doing learning activities.The main objective of this program is to provide fun and engaging English language instruction for children so that they can learn with high enthusiasm and enthusiasm. In addition, this program also aims to open their horizons to the culture and diversity of the English language, which will be an important capital in facing future challenges.
