A Blockchain-based Traceability System to Achieve the Quality Objectives in the Production Process of A Manufacturing Industry

Abstract

ISO 9001 is a standard for an organization that focuses on quality management. In ISO 9001, the organization must implement seven main clauses in achieving the certification or audit if the company has obtained ISO 9001 certification. One of the clauses is clause 6.2, which is related to quality objectives and focuses on process. The organization can achieve this clause if all SOPs in the organization are appropriately implemented. Therefore, if the SOP is well implemented, the process inside also runs well, and the quality objectives will be in line with the expectations. Manufacturing industry will be the case of the organization for this study. This study proposed a tracing system for the procedure in the SOP that used to achieve clause 6.2, quality objectives in ISO 9001. The database has an important role in system development because the system will store all information in it. Databases with conventional method have various weaknesses in data handling, such as centralized data storage and lack of security. Centralized data will make it difficult for each staff in the organization to access data if the main server is down. This study will focus on blockchain applied to traceability system as database technology because it can minimize the shortcomings of the database with conventional method. The results show that the data traceability system can trace procedures well and the data running well according to its function in storing data with blockchain. Based on these results, the traceability system in this study can trace procedures in achieving quality objectives in ISO 9001.
