Technological advancements have given rise to various new professions, one of which is online motorcycle taxi drivers, which facilitate people's activities. Grab, as one of the leading online transportation applications, continues to innovate to increase user engagement. This study examines the effect of application gamification and driver personal branding on Grab application user engagement, with a case study of students at the Faculty of Islamic Economics and Business (FEBI) of the State Islamic University of North Sumatra (UINSU). This study examines the effect of application gamification and driver personal branding on Grab application user engagement, with a case study of students at the Faculty of Islamic Economics and Business (FEBI) of the State Islamic University of North Sumatra (UINSU). A questionnaire was used to collect data with a quantitative causal associative approach from students who actively use Grab. The results of the analysis show that these two independent variables significantly influence user engagement. Application gamification, through elements such as points, cashback, voucher exchange, and level achievement, is proven to have a stronger influence in increasing user motivation and interaction. Meanwhile, driver personal branding, which includes professionalism and a positive image, also contributes significantly to increasing user trust and loyalty. Although gamification has a more dominant impact, the combination of both factors is crucial to provide a positive customer experience, which is engaging and sustainable, ultimately driving deeper engagement with the Grab platform.
