Assessing the Effectiveness of UI/UX Design in Open Government Data Portal

The ability of the public to access and use an Open Government Data Portal (OGDP) is essential for unlocking the potential of Open Government Data (OGD). Through OGDP, the government facilitates public access to its data and, at the same time, supports broader open government initiatives. The accessibility and usability of OGDPs remain critical, as they enable the public to engage with and derive value from OGD. To deepen understanding of these aspects, this study assesses the effectiveness of the OGDP user interface (UI) and user experience (UX) design through an evaluation of the Satu Data Indonesia (SDI) portal, the Indonesian national OGDP. The study involves ten participants in a 30‐minute session using the SDI portal to complete three tasks, followed by a survey. The findings indicate that most participants experienced difficulties in searching for datasets, which negatively affected their willingness to use the SDI portal in the future.
