%X Abstract: The Effect of Problem Based Learning in Improving Self-Efficacy and Learning Outcomes. This research aimed to figure out  the effect of  Problem Based Learning in improving self-efficacy and learning outcomes. The sample were students in SMPN 4 Metro chosen by purposive sampling. The design was pretest and posttest non-equivalent. The learning outcomes data were obtained from the average value of pretest, posttest, and N-gain that were analyzed by t-test. Self-efficacy data were obtained from observation and self assesment then were analyzed descriptively. The result showed  that student’s learning outcomes significantly increased that shown by the experiment class average value of N-gain (70,44) was higher than control class (48,33).  Beside that, self-efficacy experiment class was “high” criteria (83,85).  Therefore, it can be concluded that Problem Based Learning improves self-efficacy and student’s learning result significantly.    Keywords: learning outcomes, PBL, self-efficacy     Abstrak: Pengaruh Problem Based Learning dalam Meningkatkan Self-Efficacy dan Hasil Belajar. Tujuan penelitian ini adalah untuk mengetahui pengaruh model PBL terhadap self-efficacy dan hasil belajar siswa. Sampel adalah siswa di SMPN 4 Metro yang dipilih dengan teknik purposive sampling.  Desain penelitian ini adalah kelompok  pretest-postest tak ekuivalen. Data hasil belajar siswa yang diperoleh dari nilai pretest, posttest, dan N-gain yang dianalisis menggunakan uji-t. Data self-efficacy diperoleh melalui observasi dan penilaian diri kemudian dianalisis secara deskriptif. Hasil penelitian menunjukkan hasil belajar siswa meningkat secara signifikan dengan rata-rata nilai N-gain kelas eksperimen lebih tinggi (70,44) dibanding kelas kontrol (48,33). Selain itu self-efficacy siswa kelas eksperimen  berkriteria tinggi (83,85).  Oleh karena itu, pembelajaran menggunakan model PBL berpengaruh meningkatkan self-efficacy dan hasil belajar siswa secara signifikan.    Kata kunci: hasil belajar,  PBL dan self-efficacy
