Abstract

Exchange rate fluctuations are one of the main risks affecting the financial stability of multinational companies, including the digital banking sector in Indonesia. This study aims to analyze the impact of exchange rate fluctuations on the company's financial performance by using a case study on Bank BNI Digital. The financial data used covers the period January 2015 to December 2024, including variables such as exchange rate (IDR/USD), revenue, operating expenses, net profit, equity, liabilities, and exchange rate volatility. A machine learning-based predictive approach was applied through the Random Forest and XGBoost algorithms to evaluate the relationship between exchange rate fluctuations and the company's financial performance. The results showed that exchange rate fluctuations have a weak linear relationship with financial performance, especially company revenue, with a correlation coefficient of 0.01. Nevertheless, the simulation of the impact of the exchange rate on net profit shows that the company is able to maintain financial stability in a scenario of moderate exchange rate changes (±15%). The feature importance analysis of the XGBoost model shows that revenue and operating expenses are the dominant factors affecting financial performance, while exchange rates contribute less. Based on these findings, the study recommends the implementation of forward contracts to manage exchange rate risk, natural hedging strategies to balance currency exposure, and optimization of operational efficiency as a risk mitigation measure. This research provides strategic insights for Bank BNI Digital and similar companies in designing a resilient risk management strategy against exchange rate fluctuations in the global market.

Abstract

Pytixs faces the challenge of defining and developing their online ticketing web application based on monolithic infrastructure and hosted on VPS (Virtual Private Server). This monolithic structure causes difficulties in scalability, maintenance, and the development of efficient new features. Therefore, migration to the microservices architecture hosted on AWS (Amazon Web Services) is considered a solution that can improve system performance, scalability, and flexibility. The study aims to evaluate and implement the transformation of Pytixs online ticketing web applications from a monolithic VPS-hosted infrastructure to a microservices architecture hosted on AWS. The migration process involves dismantling a monolithic service into several small, independent services, which communicate through the RESTful API. In addition, AWS provides a range of services that support microservices, such as Amazon ECS, Amazon Lambda, and Amazon RDS, which help in improving efficiency and infrastructure management. The results of this study show that migration to the microservices architecture hosted on AWS provides significant improvements in terms of system scalability and performance. In addition, application development and maintenance time is drastically reduced, allowing the development team to respond to business needs faster and more efficiently. This Pytixs case study provides practical guidance and insight to other companies facing similar challenges in upgrading their web applications.
