Abstract

Student data management in Indonesian higher education institutions continues to face challenges such as data duplication, academic record manipulation, limited transparency, and weak interoperability caused by centralized databases. These issues hinder institutional credibility, administrative efficiency, and trusted academic governance. This study aims to conceptually develop a blockchain based framework to enhance data integrity, transparency, and efficiency in student data management. Using a qualitative descriptive and comparative approach, the research analyzes existing blockchain models and integrates technological and managerial perspectives to design a permissioned blockchain system supported by smart contracts. The proposed framework focuses on automating academic data validation, strengthening access control, and enabling secure inter-institutional data exchange. Comparative findings indicate that blockchain offers immutability, traceability, and accountability, positioning it as a transformative innovation for academic governance. The study provides a conceptual foundation for universities and policymakers to adopt secure and interoperable blockchain-based academic data systems aligned with Indonesia digital transformation agenda in higher education. Future research is recommended to simulate or pilot the model for practical evaluation and implementation.

Abstract

The rapid growth of digital financial services has significantly increased the volume of online payment transactions, while simultaneously intensifying concerns related to transaction security, data integrity, privacy protection, and fraud due to the limitations of centralized payment architectures, which remain vulnerable to cyberattacks, data manipulation, and single points of failure. This study aims to analyze the role of blockchain technology in enhancing the se- curity of online payment transactions by examining its core characteristics, including decentralization, transparency, immutability, and smart contracts. This research adopts a conceptual and descriptive comparative approach by synthesizing recent peer-reviewed literature to evaluate blockchain-based payment systems in comparison with conventional centralized systems. The findings indicate that blockchain implementation improves transaction security by reducing fraud risks, eliminating single points of failure, ensuring tamperresistant records, and enhancing transparency and traceability, thereby increasing user trust. These improvements contribute to more reliable, transparent, and resilient digital payment infrastructures. Furthermore, blockchain technology supports the SDGs 8 (Decent Work and Economic Growth), SDGs 9 (Industry, Innovation, and Infrastructure), and SDGs 16 (Peace, Justice, and Strong Institutions), by promoting transparency, accountability, and long-term stability in digital financial ecosystems.
