Abstract

The rapid advancement of digital technologies has led to a significant increase in data volume and complexity, while traditional database systems continue to face challenges in ensuring data security, integrity, transparency, and interoperability across platforms, resulting in higher risks of data tampering, limited audit trails, and the formation of data silos. This study aims to examine and develop a blockchain integration model with conventional database systems to strengthen secure data provenance and enhance interoperability among heterogeneous databases. This research proposes a hybrid architecture that combines on data recording using a permissioned blockchain with off data storage through Relational Database Management System (RDBMS) or Not Only SQL (NoSQL) databases, where blockchain functions as a trust layer that records data hashes, metadata, and immutable change histories, while system evaluation is conducted through security testing, data integrity assessment, auditability analysis, latency measurement, throughput evaluation, data consistency analysis, and cross-platform interoperability testing. The experimental results demonstrate that blockchain integration significantly improves data security and traceability by providing transparent and tamper-resistant audit trails, while enabling secure and consistent data exchange across systems through integration modules and API gateways, despite introducing additional performance overhead compared to conventional database systems. This study concludes that integrating blockchain with conventional database systems is an effective approach for ensuring secure data provenance and interoperable database management, offering a balanced trade-off between security, transparency, and system efficiency, and presenting strong potential for further development in large-scale distributed data environments.

Abstract

This study emphasizes the significant role of destination branding elements such as culture, climate, product offerings, and government support in shaping the destination image of Ciletuh-Palabuhanratu Global Geopark. The findings show that infrastructure and people have less impact on destination image, likely due to the nature based appeal of Geopark destinations, attracting younger generations like Millennials and Generation Z, who prioritize adventure over amenities. The results suggest that enhancing product offerings, including diverse accommodations, cultural experiences, and unique natural attractions, is key to improving the destination image and overall tourist satisfaction. Additionally, the study reveals that tourist satisfaction mediates the relationship between destination image and revisit intention, meaning that a positive image alone does not directly lead to revisits. Instead, satisfaction derived from the overall experience shaped by product offerings, cultural identity, and climate determines revisit intention. To strengthen destination image and encourage revisit intention, the study recommends expanding family friendly, star rated hotels and diversifying tourism activities such as hiking, camping, and water sports. Both the public and private sectors should collaborate on these initiatives, with government support playing a critical role in enhancing destination competitiveness. These recommendations align with SDG 8 (Decent Work and Economic Growth), SDG 11 (Sustainable Cities and Communities), and SDG 12 (Responsible Consumption and Production), promoting sustainable tourism, creating jobs, and enhancing regional competitiveness through inclusive development.

Abstract

The integration of immersive technologies such as Virtual Reality (VR), (AR), and wearable devices has transformed the landscape of engineering education, offering new possibilities for interactive and outcome driven learning. This study aims to evaluate the impact of these technologies on students’ learn- ing performance, engagement, and skill acquisition within engineering learn- ing environments. Employing a quantitative research design, data were col- lected from 180 engineering students across three universities through structured pre and post tests, supported by validated engagement and usability question- naires. Statistical analyses, including paired tests and regression models, were conducted to measure the effectiveness of technology assisted learning inter- ventions compared to traditional instructional methods. The results reveal a significant improvement in students’ cognitive performance, practical task effi- ciency, and overall motivation when VR, AR, and wearable technologies were integrated into the curriculum. Moreover, students reported enhanced spatial understanding and problem solving capabilities, indicating that immersive tools foster deeper experiential learning and higher knowledge retention. The find- ings suggest that the systematic implementation of immersive technologies can significantly enhance learning outcomes, bridging the gap between theoretical knowledge and hands on engineering practice. This research highlights the criti- cal role of technology driven innovation in promoting outcome based education, providing valuable insights for educators and policymakers aiming to optimize the use of emerging technologies in engineering education.
