Digital transformation in the palm oil industry requires reliable and user-friendly systems to ensure accurate data recording and efficient operational workflows. As a critical control point within the supply chain, the weighbridge system plays a central role in verifying Tandan Buah Segar (TBS) transactions and maintaining traceable production data. However, the desktop-based weighbridge system that has been in use since 2012 still faces several usability limitations, including non-adaptive input fields, inconsistent navigation, and manual calculations that increase the risk of operational errors. Therefore, this study aims to redesign and evaluate the weighbridge system interface to improve input accuracy, reduce operator cognitive load, and support sustainable digital operations. This research applies the User-Centered Design (UCD) methodology to redesign the weighbridge system interface through four iterative stages: identifying user needs, designing alternatives, developing interactive prototypes, and evaluating usability. Data were collected through field observations, interviews, document analysis, and questionnaires. The redesigned interface resulted in a prototype capable of presenting contextual input fields, automating the calculation of average bunch weight (BJR), and streamlining workflow processes. The prototype was evaluated using Nielsen’s Heuristic Evaluation method and achieved a usability score of 89.89%, categorized as Very Attractive. Which means that the majority of evaluators have a positive view of the mobile-based weighbridge system prototype design. The results indicate that UCD effectively enhances efficiency, reduces user errors, and supports sustainable digital operations by minimizing paper-based processes and process optimization.
