Siswa memiliki peran dalam meningkatkan mutu pendidikan dengan cara menjalankan proses belajar yang baik serta mengerjakan tugas secara mandiri dan bertanggung jawab. Ini dapat dicapai apabila siswa mempunyai kemampuan self-regulated learning (SRL), yaitu kemampuan mengatur disiplin diri saat belajar. Terdapat faktor eksternal dan internal yang mendorong SLR siswa, yaitu pola asuh autoritatif (PAA) dan efikasi diri (ED). Penelitian ini hendak mengkaji peran PAA dan ED pada SRL siswa remaja di SMA Negeri 1 Ubud secara kuantitatif. Partisipan penelitian terdiri dari 198 siswa remaja di SMA Negeri 1 Ubud, yang dipilih melalui systematic random sampling. Alat ukur penelitian terdiri dari skala self-regulated learning (SRL), skala pola asuh autoritatif (PAA), dan skala efikasi diri (ED). Analisis hasil menggunakan teknik analisis regresi berganda yang mengindikasikan adanya peran PAA dan ED pada SRL sebesar 50,4% dengan signifikansi 0,000 (p<0,05). Hal ini berarti hipotesis dalam penelitian ini diterima. Secara lebih lanjut, PAA diketahui berperan secara mandiri pada SRL serta ED juga berperan mandiri pada SRL siswa remaja di SMA Negeri 1 Ubud.Students take part in improving the quality of education by studying properly and completing their tasks responsibly.
