Design, Implementation, and Evaluation of Coffee Traceability System Using UX Process

In specialty coffee commodities, tracing the origin of coffee is critical, and coffee producers need to keep all information in the coffee process to represent their customers. There are many processes involved with various stakeholders, and the challenge is collecting the data entirely, consistently, and usable. This study aims to analyze the business process of the real-world situation in coffee commodity, generate a dataset from these observations, and propose a Coffee Traceability System (CTS) design using the requirements engineering (RE) and the user experience (UX) process. A System Usability Scale (SUS) with an adjective rating scale is applied to measure the usability of the CTS with the 32 participants who need to collect the information throughout the coffee processing. The result of the study shows that the average score from SUS is 80.94, which indicates that our system is easy to use for the coffee processing experts.
