Abstract

Information system security faces serious challenges due to increasingly complex cyber attacks. Intrusion Detection Systems (IDS) require efficient approaches to handle high-dimensional data such as the NSL-KDD dataset with 41 features. This study aims to implement the Genetic Algorithm (GA) for feature selection on the NSL-KDD dataset to improve the efficiency and accuracy of network attack detection. The method used is computational experimental research, involving data preprocessing, GA implementation for feature selection, building a classification model using Random Forest, and performance evaluation based on accuracy, precision, recall, F1-score, and computation time. The results show that GA successfully reduced features from 41 to 12 features (70.7% reduction), significantly improving computational efficiency. However, model accuracy slightly decreased from 0.4973 to 0.4951, indicating that while GA is effective for feature selection, the elimination of certain features may reduce classification capability. The implication of this study is that GA can be used as a tool to simplify intrusion detection models, but it should be combined with parameter optimization and data imbalance handling to achieve more optimal performance.

Abstract

This research aims to design and build a letter archive information system at the KOFIPINDO Law Office to improve the effectiveness and efficiency of document management. The manual filing system that has been used so far poses various obstacles, such as search delays, the risk of losing documents, and low storage accuracy. To overcome these problems, this study applies the Waterfall System Development Life Cycle (SDLC) model in the process of designing and building the system. Web-based technologies used include PHP, HTML, CSS, Bootstrap, and MySQL. The results of the study show that the developed letter archive information system is able to simplify the process of storing, searching, and managing incoming and outgoing letters in a faster, structured, and safer manner. The implementation of this system not only improves administrative performance, but also strengthens accountability and supports the need for professional legal documentation within the KOFIPINDO Law Office. Thus, this web-based mail archive information system can be a strategic solution in modernizing legal document management.

Abstract

This study discusses the implementation of innovative software to improve the efficiency of information management systems at Bank Syariah Indonesia (BSI). The backround of this research begin with growing need for effective and efficient information systems in the digital era, particularly in Islamic banking which requires compliance with sharia principles. The purpose of this study is to identify how software innovation can support better service, data security, and operational effectiveness at BSI. By employing a qualitative descriptive methodology along with a literature review, this research analyzes various technological innovations such as artificial intelligence (AI), big data, and Customer Relationship Management (CRM) applications in Islamic banking systems. The findings show that the adoption of modern information technology significantly enhances operational efficiency, service quality, and competitiveness. The conclusion highlights that software innovation integrated with sharia principles strengthens the management information system and supports BSI’s vision to become a global center of Islamic finance. Future development of software should focus on improving data security and adapting to advanced technologies to further enhance customer service quality.
