General Background: Academic engagement is crucial for maintaining concentration and optimizing student learning processes. Specific Background: Observations among Biology students at the University of Lampung indicated decreased classroom focus, frequent gadget use during lectures, and low motivation in completing practicum reports. Knowledge Gap: Empirical studies examining the relationship between social support and academic flow among Biology undergraduate students remain limited. Aims: This study investigates the relationship between social support and academic flow among fourth-semester Biology students at the Faculty of Mathematics and Natural Sciences, University of Lampung. Results: Using a correlational quantitative design with Likert-scale psychological instruments and SPSS 25.0 analysis, the findings showed a significant positive relationship between social support and academic flow, with a correlation coefficient of r = 0.265 and a significance value of 0.019 (<0.05). Novelty: This study presents quantitative evidence specifically examining academic flow in Biology students through standardized measurement of social support variables. Implications: The findings indicate that strengthening interpersonal support systems is associated with improved student engagement and concentration during academic activities, providing considerations for educational stakeholders in supporting learning experiences. Highlights: Interpersonal Assistance Is Statistically Associated With Optimal Learning Immersion. Quantitative Measurement Confirms Moderate Relational Strength Between Examined Variables. Learner Engagement Challenges Relate to Reduced Practicum Completion Motivation and Lecture Focus.
