Design of dual blockchain-based with Point of Authority for halal traceability system application on fresh meat-based supply chain

Abstract

This study aims to design a halal fresh meat traceability system based on dual blockchain technology and the Internet of Things (IoT). This system will utilize the Point of Authority (PoA) method to validate information on the implementation of halal assurance in the halal fresh meat food chain based on beef, starting from the slaughterhouse, halal slaughterer, and slaughterhouse supervisor. This system will also provide information on temperature and humidity conditions in the delivery service of halal fresh meat products to consumers in traditional markets. In this study, we developed a software system with the waterfall method for a web-based halal traceability system using the Hypertext Preprocessor (PHP) programming language and the Laravel framework, blockchain using SQLite, and IoT technology using C programming. Consumers can obtain product delivery information, halal fresh product assurance information, and halal guarantor information transparently in the halal fresh meat supply chain by scanning the product's Quick Response Code (QR code). This study offers a basic framework for policymakers to improve the halal integrity of the halal fresh meat supply chain, and the concept of halal assurance in traditional markets. It also allows consumers to monitor the halal status of fresh beef products in conventional markets. This study contributes to the beef-based halal fresh beef supply chain research by developing a traceability system for halal fresh meat using blockchain and IoT.
