This study aims to examine the influence of the campus environment on students’ learning interest in Civic Education at Universitas HKBP Nommensen Pematangsiantar. The research employs a qualitative descriptive approach to explore how both physical and social aspects of the campus environment affect students’ motivation and engagement in academic activities, particularly in Civic Education. Data were collected through observation and questionnaires distributed to students enrolled in the Civic Education program. The findings reveal a strong and significant correlation between the campus environment and students’ learning interest, with a correlation coefficient of 0.82, indicating a very strong relationship. Furthermore, the study finds that students’ learning interest has a strong influence on academic achievement, with a correlation value of 0.70. Another finding indicates a moderate correlation of 0.51 between campus environment and learning interest when analyzed independently. The results of hypothesis testing also show that the F-calculated value (6.33) exceeds the F-table value (3.15), confirming the significance of the relationship. These findings suggest that a conducive and supportive campus environment—encompassing clean and organized facilities, healthy peer interactions, and constructive lecturer-student engagement—can enhance students' interest and academic performance in Civic Education. The study contributes to a deeper understanding of the non-academic factors that influence learning motivation and offers practical recommendations for universities to strengthen campus culture and learning infrastructure. It also provides valuable insight for future research in educational psychology and civic education development at the higher education level.
