Data were analyzed using multiple linear regression with hypothesis testing through Partial Test (t-test), Simultaneous Test (F-test), and the Coefficient of Determination (R²). The results of data processing using SPSS version 25 showed that the implementation of Project-Based Learning (PjBL) had a positive and significant effect on students’ academic achievement. Time management also had a positive and significant effect on academic achievement. Likewise, learning motivation had a positive and significant effect on academic achievement.
