Abstract
The study was aimed to determine the effect of Problem Based Learning (PBL) model towards student outcomes and learning activity in optica Geometric material. The type of this research was quasy experiment. The population of this research was all of the students class X SMA Negeri 5 Medan A.Y 2014/2015 which was consist of 5 classes. X MIA 5 was choosen as experimental group and X MIA 3 as Control group by using cluster random sampling. The Instrument used was learning outcomes and student’ activity observation sheet. Based on the hypothesis of the average value, pretest shows that both of the class had the same early abilities. After the treatment, found that the average value of post-test in experimental class by using problem-based learning was 76,34 and control class by using conventional learning was 72,56. The result of test showed that data normally distribution and homegeneous. Then, was made a hypothesis experiment that giving t count (1,83)> t table(1,67), so Ha was accepted. Later, from the observation data showed that the students learning activity in experimental group was belong to the active category. Finally, it could be concluded that there was an effect of Problem based learning model towards the learning outcames and learning activity in optical geometric material.

Summary
Problem Based Learning (PBL) terhadap hasil dan aktivitas belajar siswa pada materi pokok optika geometris. Populasi penelitian adalah seluruh siswa kelas X SMA Negeri 5 Medan T.P. 2014/2015 yang terdiri dari 5 kelas. Instrumen yang digunakan adalah tes hasil belajar dan lembar observasi aktivitas siswa. Berdasarkan uji beda nilai rata-rata pretes menunjukkan bahwa kedua kelas memiliki kemampuan awal yang sama. Diperoleh nilai rata-rata postes kelas eksperimen dengan problem based learning 76,34 dan kelas kontrol dengan pembelajaran konvensional 72,56. Hasil pengujian menunjukkan bahwa data berdistribusi normal dan homogen. Selanjutnya dari data observasi menunjukkan bahwa aktivitas belajar siswa dalam kelompok eksperimen termasuk kategori aktif. Akhirnya dapat disimpulkan bahwa terdapat pengaruh model problem based learningterhadap hasil dan aktivitas belajar siswa pada materi pokok optika geometris.
