PT Nuvotek, a subsidiary of PT Duta Laserindo Metal (PT DLM) focusing on technology development, has initiated the digital transformation of the 5S concept through the launch of the mobile-based Disiplean application and the web-based Disiplean Analytics application. These applications are designed to ensure the consistent implementation of 5S in the workplace. Currently, PT Nuvotek is focused on developing Disiplean Analytics version 1.0 as a Minimum Viable Product (MVP). The product manager aims to ensure that this application meets technical specifications and provides an intuitive user experience. Preliminary studies indicate that 80% of the issues with the Disiplean Analytics application are related to usability. Consequently, the application will undergo a usability evaluation, and improvement proposals will be formulated based on the evaluation results. The usability evaluation methods applied include usability testing and usability inquiry. Usability testing was conducted through performance measurement, Retrospective ThinkAloud (RTA), and neuro-usability testing using electroencephalography (EEG). Meanwhile, usability inquiry was conducted using the System Usability Scale (SUS) questionnaire. This study involved 12 participants who were new users of the application. Participants were asked to complete five tasks designed based on real-world application usage at PT DLM. Based on the results of the usability evaluation, improvement proposals were formulated using the design thinking method. The research results show that all tasks were completed effectively with a low workload. However, only tasks C, D, and E were completed efficiently. The error rate analysis identified 27 types of errors, while the RTA generated 33 comments related to usability issues. The SUS questionnaire results yielded a score of 68,75, which is interpreted as marginally high. Based on the usability evaluation results, 22 improvement proposals were designed using the design thinking process, including adjustments to menu and filter layouts, changes to the "Diangkat Meeting" system, improvements to colors and icons, the visualization of the "Lokasi" filter into a table format, and the addition of elements such as a search bar, snackbar, and labels.
