Description
Summary:Along with technological developments, the number of digital payment services that are present in Indonesia continues to increase. It provides many digital payment service options that can be used by users. It creates new problem; the spread of money owned by users to various digital payment services. This final project intends to design an application prototype that can integrate various digital payment services with comprehensive functionality utilizing a user-centered design (UCD) methodology to create a design that can meet the needs of digital payment service users who have more than 1 digital payment service as the target users. The stages of UCD that are passed include: Planning, Determining Usage Context, Determining User Needs, Designing Solutions, and Design Evaluation. Data collection was carried out using a questionnaire method with quantitative and qualitative questions to 120 respondents who met the characteristics of the user's target persona. Analysis of the collected data has succeeded in defining 13 features that are implemented in the form of low-fidelity and high-fidelity prototypes, which are main Menu and Dashboard, Access to Digital Payment Services, Automatic Financial Recording, Pay, QR Scanner, Inquiry Page, Transfer, Top Up, Autop Up, Financial Dashboard, Account, Budget, and Notifications. These features are designed and tested in three iterations or stages using the task completion rate and single ease questions (SEQ) test methods to meet the usability goal of 'have a good utility'; intrinsic motivation inventory (IMI) with a value/usefulness subscale to meet user experience goal 'helpful'; and system usability scale (SUS). The highest scores achieved by the prototype design for each test method were task completion rate = 100%; SEQ = 6.58 of 7; IMI value/usefulness = 6.5 out of 7; and SUS = 89 out of 100. Thus, it is concluded that the prototype design that has been made has succeeded in becoming a digital payment service application design that meets the needs of its target users with a satisfactory rating score.
