User Interface and User Experience Designing in the Kapustakan System Using User Centred Design Approach (Case Study: Keraton Ngayogyakarta Hadiningrat)

Abstract

The Kapustakan System is a digital collection management system for the Keraton Ngayogyakarta Hadiningrat. The Kapustakan System is being developed to present various museum collections in digital representation, facilitating access to knowledge search, cross-referencing, and encouraging research. This system needs an interface design that takes into account both the User Interface (UI) and the User Experience (UX) to make users feel comfortable when they use it. This paper describes the UI/UX design process for the Kapustakan System using the user-centred Design (UCD) method, which consists of five stages: planning the human-centred design, specifying the context of use, specifying user and organizational requirements, producing design solutions, and evaluating designs against user requirements. The UCD method focuses on the direct involvement of prospective users so that they can influence the design results that meet their needs and desires. The result of this research is a prototype design of the Kapustakan System that has been validated through usability testing of potential users. The parameters tested in usability testing are success rate, efficiency, error rate, and satisfaction. The test's success rate is 93.75%, its efficiency is 90.27%, its error rate is 3.73%, and its satisfaction is 86.25.

User Experience Testing on JoinGeek Admin using a User Experience Questionnaire and Usability Testing

“…These categories will be evaluated using the benchmark value limits provided in Table 1. Usability testing in this study is used to test the interaction between users and the system through a series of task scenarios related to the interface to respondents [14]. Usability testing is performed after respondents complete the system's UEQ questionnaire prior to redesign.…”

“…By measuring the success rate, it is possible to gauge the extent to which users can achieve their goals and how effective the system is in supporting their interactions. There are various criteria for measuring success rate [14]: a) Successful (S): Indicates that the respondent successfully completed the task in the given scenario without any errors. b) Partially Successful (PS): Indicates that the respondent was able to complete the task in the scenario, but errors were made during the process.…”
