Partisipasi siswa dalam OSIS masih menjadi perhatian di berbagai sekolah, termasuk di SMA Negeri Banda Aceh. Interaksi teman sebaya diduga menjadi salah satu faktor yang memengaruhi minat siswa untuk bergabung dalam OSIS, namun bukti empiris masih terbatas. Penelitian ini bertujuan mendeskripsikan interaksi teman sebaya, minat mengikuti OSIS, serta menganalisis pengaruh keduanya. Penelitian ini menggunakan pendekatan kuantitatif dengan jenis penelitan asosiatif kausal. Penelitian ini melibatkan seluruh siswa kelas X dan XI dari SMA Negeri 3 Banda Aceh dan SMA Negeri 16 Banda Aceh yang berjumlah 845 siswa sebagai populasi, dengan 271 siswa dipilih sebagai sampel melalui teknik stratified random sampling menggunakan rumus Slovin (taraf signifikansi 5%). Data dikumpulkan melalui dua angket skala Likert yang disebarkan secara online melalui Google Form. Analisis data dilakukan menggunakan analisis deskriptif dan regresi linear sederhana. Hasil penelitian menunjukkan sebagian besar siswa memiliki interaksi teman sebaya kategori tinggi (59%), hampir separuh siswa memiliki minat mengikuti OSIS kategori tinggi (40%), serta terdapat pengaruh positif dan signifikan interaksi teman sebaya terhadap minat mengikuti OSIS (β=0,617, p

Student participation in the Student Council remains a concern in various schools, including at Banda Aceh State High School. Peer interaction is believed to be one of the factors influencing students’ interest in joining the Student Council, but empirical evidence remains limited. This study aims to describe peer interaction and interest in joining the Student Council, as well as to analyze the influence of both. This study employs a quantitative approach using an associative-causal research design. The study involved all 10th and 11th-grade students from Banda Aceh State High School 3 and Banda Aceh State High School 16, totaling 845 students as the population, with 271 students selected as the sample through stratified random sampling using the Slovin formula (5% significance level). Data were collected through two Likert-scale questionnaires distributed online via Google Forms. Data analysis was conducted using descriptive analysis and simple linear regression. The results of the study indicate that the majority of students have high-level peer interactions (59%), nearly half of the students have a high level of interest in joining the Student Council (40%), and there is a positive and significant influence of peer interactions on interest in joining the Student Council (β=0.617, p
