The population in this study consisted of all seventh grade students at SMP Negeri 5 Pematangsiantar, totaling 158 students. The sampling technique used was proportionate stratified random sampling, resulting in a sample of 113 students. Data were collected through questionnaires and documentation. The research instruments were tested using validity and reliability tests. The data analysis techniques included classical assumption tests, multiple linear regression analysis, t-test, F-test, and coefficient of determination test (R²). The results of the study showed that: (1) learning interest had a positive and significant influence on students’ learning outcomes, proven by a significance value of 0.000 < 0.05 and a t-value of 7.489; (2) peer environment had a positive and significant influence on students’ learning outcomes, proven by a significance value of 0.000 < 0.05 and a t-value of 4.371; and (3) learning interest and peer environment simultaneously had a positive and significant influence on students’ learning outcomes, proven by a significance value of 0.000 < 0.05 and an F-value of 72.040. The coefficient of determination test (R²) showed a value of 0.567 or 56.7%, which means that learning interest and peer environment contributed 56.7% to students’ learning outcomes, while the remaining 43.3% was influenced by other factors outside this study.
