Abstract

A diploma management system presently utilized in Indonesia remains a manual, paper-based approach.
This system exhibits multiple deficiencies, including diploma forgery, lost diplomas, damaged diplomas,
hand-written diplomas, data transparency difficulties, and challenges in diploma verification. A software
application named e-Jazah was created to administer digital diplomas utilizing blockchain technology to
resolve these challenges. The construction of this new system seeks to mitigate the issues that emerged in
the prior manual system. Blockchain technology is employed to ensure data integrity. The solution is
designed to utilize a fundamental characteristic of blockchain technology—its tamper-resistant quality—
which protects data integrity from alteration or corruption attempts. The system is decentralized,
comprising numerous peers that operate the blockchain network. The blockchain network is constructed
using Hyperledger Fabric technology. Hyperledger Fabric was selected due to its status as a permissioned
blockchain and its user-friendly smart contract development features. The system consists of a frontend
component serving as the user interface, a backend component linking the frontend to the blockchain
network, and the blockchain network itself, with the update aimed at enhancing the UI/UX to improve user
experience. The established system streamlines the fundamental procedure of diploma issuance via its
functional specifications. The technology may authenticate diplomas using two methods: the diploma
number and a PDF document.
