The implementation of a flap gate-based physical access control system at the Rectorate Building of UIN Raden Intan Lampung aims to ensure building security. However, neglecting ergonomic aspects risks triggering systemic security breaches due to security-bypassing behaviors, such as tailgating by staff and leaving emergency gates open due to jammed trolleys. This study aims to quantitatively evaluate and compare the usability of the flap gate device based on two internal user groups' perceptions. The evaluation utilized the System Usability Scale (SUS) through a standardized 10-item 5-point Likert scale questionnaire distributed to 30 respondents, selected via purposive sampling for Administrative Staff and a census for Cleaning Staff. The quantitative analysis yielded a global average SUS score of 69.00 (Acceptable/Marginal High, Grade C, Good). Comparative analysis identified a sharp perception gap between Administrative Staff (72.12; Grade B/C) and Cleaning Staff (62.75; Grade D/OK), alongside a drastic decline in the learnability dimension to 60.83. These findings prove that operational bottlenecks do not merely compromise comfort but undermine the building's primary security function. This research offers empirical, theoretical, and practical contributions by proving the causality between ergonomic barriers and security breaches, as well as formulating a hybrid mitigation roadmap. Reconfiguring gate delay intervals, adding lower infrared sensors, and providing a dedicated logistics lane serve as urgent solutions to maintain security integrity.
