Perancangan Arsitektur dan Implementasi Backend Sistem Informasi Rantai Pasok SAF Berbasis Blockchain

Abstract

Penerapan Sustainable Aviation Fuel (SAF) memerlukan sistem informasi yang mampu menjamin ketertelusuran data, keamanan transaksi, dan integritas informasi sepanjang rantai pasok. Penelitian ini bertujuan merancang arsitektur serta mengimplementasikan backend sistem informasi rantai pasok SAF berbasis blockchain menggunakan Hyperledger Fabric . Metode yang digunakan adalah Design Thinking yang meliputi tahap eksplorasi, pendefinisian masalah, ideasi, pengembangan prototipe, dan validasi. Backend dikembangkan menggunakan Node .js, Express.js, REST API, MongoDB, dan CouchDB serta diintegrasikan dengan jaringan Hyperledger Fabric melalui smart contract untuk mendukung pencatatan data, pengelolaan hak akses berbasis Role-Based Access Control (RBAC), dan mekanisme traceability. Implementasi menghasilkan layanan backend yang mampu menghubungkan aplikasi dengan blockchain, memproses transaksi secara aman, serta mendukung pencatatan data rantai pasok SAF secara terintegrasi. Pengujian menggunakan Black Box Testing dan Postman menunjukkan seluruh endpoint REST API berjalan sesuai fungsi yang dirancang dan berhasil berkomunikasi dengan jaringan blockchain. Hasil penelitian menunjukkan bahwa backend yang dikembangkan mampu meningkatkan keamanan, transparansi, dan ketertelusuran data sehingga mendukung pengelolaan rantai pasok SAF yang lebih andal.

The implementation of Sustainable Aviation Fuel (SAF) requires an information System capable of ensuring data traceability , Transaction security, and information integrity throughout the supply chain. This study aims to design the architecture and implement the backend of a blockchain -based SAF supply chain information System using Hyperledger Fabric . The research employed the Design Thinking approach, consisting of exploration, problem definition, ideation, prototype development, and validation. The backend was developed using Node .js, Express.js, REST API, MongoDB, and CouchDB, and integrated with the Hyperledger Fabric network through smart contracts to support data recording, Role-Based Access Control (RBAC), and blockchain traceability . The implementation produced backend service s capable of connecting the application with the blockchain , securely processing Transaction s, and managing SAF supply chain data in an integrated manner. Functional validation using Black Box Testing and Postman confirmed that all REST API endpoint s operated as expected and successfully communicated with the blockchain network . The results indicate that the developed backend improves data security, transparency, and traceability , thereby supporting a more reliable SAF supply chain management System.
