The congregation attendance recording at the HKBP Sentosa Tanjung Morawa Church is still done manually using paper, causing the data recording and recapitulation process to take quite a long time, potentially causing recording errors, and making it difficult to search for attendance data in a certain period. This study aims to design a UI/UX prototype for a congregation attendance e-counter system based on figma using the design thinking method. The design thinking stages applied include empathize, define, ideate, prototype, and test. The results of the study are a prototype of a congregation attendance e-counter system that has login, dashboard, congregation attendance recording, attendance statistics, attendance history, report sending, and logout features. The prototype was then tested using the System Usability Scale (SUS) method on 20 respondents. The test results showed an average SUS score of 80.625 which is included in the Acceptable category, obtained a Grade A, and is in the Excellent category.
