Persamaan regresi yang diperoleh adalah Ŷ = 5,274 + 0,749X₁ + 0,492X₂ dengan R² = 0,791.

A quantitative causal design was employed with a population of 105 students; 83 were selected using Slovin's formula (5% margin of error) and proportionate random sampling. Data were collected via a five-point Likert-scale questionnaire and analyzed using multiple linear regression with IBM SPSS Statistics 26. Results demonstrated that: (1) entrepreneurial practice had a significant partial positive influence on entrepreneurial motivation, t(81) = 10.222, p = .000; (2) family environment had a significant partial positive influence on entrepreneurial motivation, t(81) = 9.995, p = .000; and (3) both variables jointly exerted a significant simultaneous positive influence, F(2, 80) = 151.108, p = .000. The regression equation was Ŷ = 5.274 + 0.749X₁ + 0.492X₂, with R² = .791. The effective contributions of entrepreneurial practice and family environment were 40.3% and 38.8%, with relative contributions of 51% and 49%, respectively. These findings indicate that both variables are significant determinants of vocational students' entrepreneurial motivation.
