The rapid growth of digital technologies has significantly increased the complexity and frequency of cyber threats, making network security a critical concern in modern information systems. Traditional security approaches, such as rule-based and signature-based systems, are often limited in detecting sophisticated and unknown attacks. Therefore, this study proposes an Anomaly-Based Intrusion Detection System (AbIDS) utilizing machine learning and deep learning techniques to enhance detection capabilities. The research adopts a Design Science Research approach, involving stages of problem identification, data collection, preprocessing, model development, system implementation, and evaluation. Several models, including Decision Tree (DT), Support Vector Machine (SVM), Convolutional Neural Network (CNN), and Long Short-Term Memory (LSTM), are implemented and compared. The results indicate that deep learning models, particularly LSTM and CNN, outperform traditional machine learning methods in terms of accuracy, precision, recall, and F1-score, while maintaining a lower false positive rate. Additionally, the integration of incremental learning enables the system to adapt to new attack patterns without requiring complete retraining, improving scalability and real-time performance. Despite the promising results, challenges such as computational complexity and false positives remain. Overall, the proposed IDS model demonstrates strong potential as an effective and adaptive solution for enhancing network security in dynamic environments.

Obtaining high-quality, diverse, accurate datasets for sentiment analysis has always been a significant challenge. Traditional approaches include annotators, which may introduce bias to datasets and are also time-consuming and expensive. These types of datasets may also not represent the variety needed to train robust and generalizable sentiment analysis models. This study introduces a novel combination of techniques to approach the problem with a novel solution. The proposed system, SentiGEN includes the use of a transformer, T5, fine-tuned and optimized using an evolutionary algorithm to generate high-quality, diverse, accurate data for sentiment analysis. The generated data is validated using XLNet to ensure high sentiment accuracy. This combination of technologies has proven successful based on the results derived from evaluating multiple models. From complex transformers such as BERT to more straightforward approaches like KNN, those trained using synthetic data demonstrated superior performance compared to their counterparts trained on real data. This enhancement in predictive accuracy was observed when evaluated on benchmark datasets such as SST-2 and Yelp. SentiGEN can generate high-quality, diverse, accurate, realistic data for sentiment analysis and successfully increased the performance of models trained on synthetic data compared to the same model trained on real data.

Based on the Man 2 Tapanuli Tengah researchers' observations, it was shown that teaching at Aqidah Akhlak was constrained by students' low motivation to learn. The purpose of this study is to elucidate the causes of students' low motivation to learn Akida Aflaq. The reasons for the low learning motivation of Akida-Aklak students are that teachers still use traditional models, students get bored quickly because teachers do not use media effectively in learning, and students do not participate actively in learning because they do not have the courage to discuss or express their opinions during learning. Various learning models and methods, such as the Student Times Achievement Division learning model, can be applied to these problems to motivate students to learn. This study is an experimental study aimed at checking some things and confirming their results in order to test something. Data collection techniques can also be measured using questionnaires, validity tests, reliability tests, etc. Therefore, the obtained research results show that the learning model is not correctly applied by the teachers when learning, so that the students with Akida-Aklak have low learning motivation, get bored easily, and lack the courage to discuss and express their opinions during learning. To overcome this problem, it is very important to pay attention to the models and media used for learning so that teachers can adequately achieve the learning objectives.

This research was conducted as a response to students' low interest in learning in English subjects at Al Amin Islamic Middle School, North Cikarang, Bekasi Regency. Several factors that cause this low interest include the lack of attractiveness of the material, monotonous teaching methods, and the lack of connection between English language material and students' daily lives. The impact is a decrease in students' interest in these subjects, which can affect their interest in learning. In an effort to increase students' interest in learning, the Problem Based Learning (PBL) learning model is used, where the teacher gives students ample opportunities to determine problem topics that are relevant to the learning material, even though the teacher has prepared the material that will be discussed in the lesson. The learning process is focused on students' abilities to solve problems systematically and logistically. This research uses a qualitative approach with descriptive methods. Through observation, interviews and documentation, the research results show that the application of the PBL learning model at Al Amin Islamic Middle School, North Cikarang, Bekasi Regency can increase students' interest in learning. English teachers who use the PBL model get good responses from students, where students are active in the teaching and learning process, ask questions actively, and are able to answer questions well and appropriately during discussions. The PBL learning model also encourages students to be more diligent in doing their assignments and provides high motivation to learn. Students find it easier to solve problems and are able to apply the knowledge they have.
