Abstract

This research aims to design and build a Non-Fungible Token (NFT) based digital certificate management application on the Solana blockchain network. This application enables users to create, verify, and transfer certificates in the form of secure and decentralized non-fungible tokens (NFTs). Testing was conducted in two main aspects: functional and performance. The functional testing results showed a 100% success rate, indicating that all the application's main features performed as expected. In terms of performance, NFT creation took an average of 29 seconds for 0.00008 SOL, NFT verification took 1.5 seconds at no cost, and NFT transfer took 19 seconds at the same cost as creation. These results show that the application is able to perform its functions efficiently and economically on top of the Solana network. This research contributes to the utilization of blockchain technology for transparent and secure digital document management.

Abstract

The rapid development of information technology (IT) has affected many sectors, including higher education. Universitas Pembangunan Jaya (UPJ) implemented two versions of COBIT, COBIT 5.0 and COBIT 2019, to improve their IT management. This research aims to compare the effectiveness of the two versions in supporting IT management at UPJ. The research method used is a qualitative approach with a case study involving in-depth interviews, direct observation, and documentation analysis. The data obtained was analyzed using thematic and comparative approaches. The results showed that COBIT 2019 is more flexible, allows customization to the specific conditions of the university, and improves collaboration between departments. Meanwhile, COBIT 5.0 tends to be more rigid and less adaptive to rapid changes. This research concludes that COBIT 2019 is more effective in IT management at UPJ, as it provides greater flexibility in the management of IT resources and response to environmental changes.
