Penelitian ini bertujuan untuk mengetahui penerapan model Problem Based Intruduction di kelas XI SMA Negeri 1 Montasik, dan untuk mengetahui seberapa besar pengaruh model Problem Based Intruduction (PBI) terhadap hasil belajar SMA siswa kelas XI di SMa Negeri 1 Montasik. Penelitian ini menggunakan pendekatan kuantitatif dengan jenis penelitian Pre-experimental design, berbentuk one group pretest posttest design yang mana hanya terdapat satu kelompok. Adapun yang menjadi populasi pada penelitian ini adalah seluruh siswa kelas XI yang berjumlah 6
kelas. Sampel pada penelitian ini ialah siswa kelas XI IPA 3 yang berjumlah 34
siswa. Adapun teknik pengambilan sampel dalam penelitian ini menggunakan
teknik purposive sampling. Teknik pengumpulan data yang digunakan adalah
observasi, tes dan dokumentasi. Pada teknik analisis data menggunakan uji
normalitas, uji homogenitas, dan uji t-test beda dua rata-rata. Hasil nilai rata-rata
sebelum menggunakan model Problem Based Intruduction (PBI) yaitu 60 dikategorikan cukup dan setelah diberikan perlakuan nilai rata-rata siswa yaitu 80 dikategorikan baik, hal ini membuktikan bahwa terjadi perubahan yang signifikan terhadap hasil belajar siswa. Berdasarkan hasil nilai uji thitung > ttabel atau 17.572 > 2.036 pada taraf signifikansi α = 5% (0,05), maka HO ditolak dan Ha diterima atau terdapat pengaruh yang nyata (signifikan) pada hasil belajar siswa sebelum dan sesudah menggunakan model Problem based Intruduction (PBI) pada mata pelajaran Sejarah. Dengan demikian, maka penggunaan model Problem Based Intruduction (PBI) berpengaruh terhadap hasil belajar Sejarah siswa kelas XI IPA 3 di SMA Negeri 1 Montasik.

This study aims to determine the application of the Problem Based Intruduction model in grade XI of SMA Negeri 1 Montasik, and to find out how much the influence of the Problem Based Intruduction (PBI) model on the learning outcomes of high school students in grade XI at SMA Negeri 1 Montasik. This study uses a quantitative approach with the type of Pre-experimental design research, in the form of a one group pretest posttest design where there is only one group. The population in this study is all grade XI students totaling 6 classes. The sample in this study is 34 students in grade XI Science 3. The sampling technique in this study uses the purposive sampling technique. The data collection techniques used are observation, tests and documentation. The data analysis technique uses a normality test, a homogeneity test, and a t-test with a difference of two averages. The average score before using the Problem Based Intruduction (PBI) model, which is 60, is categorized as sufficient and after being given the treatment of the student's average score, which is 80, is categorized as good, this proves that there is a significant change in student learning outcomes. Based on the results of the ttable > tcount test score or 17,572 > 2,036 at the significance level of α = 5% (0.05), the HO was rejected and Ha was accepted or there was a real (significant) influence on student learning outcomes before and after using the Problem based Intruduction (PBI) model in the History subject. Thus, the use of the Problem Based Intruduction (PBI) model has an effect on the learning outcomes of History students in grade XI Science 3 at SMA Negeri 1 Montasik.
