The collateral auction system in banking faces challenges in terms of scalability, data security, and technology integration. This study aims to analyze and enhance the application architecture of the collateral auction system at BNI46 using the TOGAF (The Open Group Architecture Framework). The target architecture is then designed based on the Architecture Development Method (ADM) phases in TOGAF, covering aspects of Business Architecture, Information Systems Architecture, and Technology Architecture. The research methodology includes observations, interviews, and literature studies to identify weaknesses in the existing system and business requirements. TOGAF is applied as a systematic approach to designing a more flexible, secure, and efficient architecture. Technologies such as containerization, Kubernetes, and a zero-trust security model are employed to improve system efficiency. The study results indicate that the implementation of TOGAF provides a structured approach to developing an architecture that is more flexible and business-oriented. With these improvements, the collateral auction system is expected to provide better services for customers, enhance the efficiency of asset management in banking, adapt to evolving business needs, and strengthen the bank's competitiveness in the digital era.

Flight delays have become a major issue in the aviation industry, impacting operational efficiency and customer satisfaction. This study proposes a CatBoostClassifier-based approach combined with Feature Engineering, Bayesian Optimization, and Random Over Sampling techniques to improve the accuracy of flight delay predictions. Based on model evaluation results, the use of Feature Engineering and Bayesian Optimization enhances performance compared to the baseline CatBoost model. The CatBoost+FE+Bayes combination achieves an accuracy of 83.32%, higher than the unmodified CatBoost model, which only reaches 82.95%. However, applying the Random Over Sampling technique in the CatBoost+FE+Bayes+ROS combination decreases model performance, reducing accuracy to 81.44%. Regarding other metrics, the CatBoost+FE+Bayes model demonstrates the highest F1-score of 0.62, indicating a balance between precision and recall. Additionally, the Area Under Curve (AUC) analysis reveals that CatBoost+FE+Bayes has the highest AUC value of 0.7793, followed by CatBoost+FE at 0.7768, and the unmodified CatBoost model at 0.7643. Meanwhile, the application of ROS leads to a decrease in AUC value to 0.6787. These findings suggest that utilizing Feature Engineering and Bayesian Optimization significantly enhances flight delay predictions. However, resampling techniques such as ROS do not always positively impact the tested model and can even degrade classification performance. The objective of this research is to develop a more accurate flight delay prediction model through the application of appropriate optimization techniques. The resulting model is expected to improve prediction quality and benefit the aviation industry by optimizing operational efficiency and minimizing the negative impact of delays on passengers.
