This study investigates the underlying factors that shape university students' inclination toward entrepreneurship, with particular attention to personality traits, familial support, and income expectations. While entrepreneurial success is often associated with traits such as self-confidence, risk tolerance, and a forward-looking mindset, encouragement from parents and the aspiration for better financial prospects also play a vital role in sparking entrepreneurial interest among students. The research involved 83 undergraduate students enrolled in the Management Study Program at the Faculty of Economics and Business, Universitas Jember, with data collection taking place between January and March 2024. A structured questionnaire was used to gather responses, which were then analyzed to examine the relationships between the three predictor variables and students' entrepreneurial interest. The findings indicate that personality traits do not significantly influence entrepreneurial interest. In contrast, both family support and income expectations demonstrate a meaningful and positive effect. These results highlight that a supportive social environment and financial motivation are key drivers in cultivating students’ interest in pursuing entrepreneurial endeavors.
