Kata Kunci: Model Pembelajaran, Hasil Belajar Siswa, Pencemaran Lingkungan
Proses pendidikan yang terencana diarahkan untuk mewujudkan suasana belajar dan
proses pembelajaran, dalam arti lain pendidikan tidak boleh mengesampingkan proses
belajar. Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran
Problem Based Learning terhadap hasil belajar siswa pada materi pencemaran
lingkungan kelas VII SMP Negeri 1 Blangjerango tahun pelajaran 2020/2021.
Penelitian ini menggunakan pendekatan kuantitatif. Instrumen yang digunakan yaitu
item tes/soal pilihan ganda yang mencakup materi pencemaran lingkungan. Populasi
dan sampel penelitian ini adalah seluruh peserta didik kelas VII yang berjumlah 50
siswa. Ada pun teknik pengumpulan data dalam penelitian ini yaitu (1) Data
kemampuan awal peserta didik dikumpulkan dalam kegiatan pretest, (2) Data
kemampuan akhir siswa (hasil belajar) dikumpulkan dengan cara pemberian tes akhir
dalam kegiatan posttest. Data dianalisis yaitu: (1) Membuat tabulasi skor pretest, skor
posttest, dan skor N-Gain, (2) Menghitung skor pretest dan posttest. (3) Menghitung
nilai N-Gain, dan (4) Uji hipotesis. Hasil penelitian diperoleh hasil uji t hitung =32,30
˃ t tabel=1,67 pada taraf signifikan 0,05. Berdasarkan hasil penelitian tersebut dapat
disimpulkan bahwa penerapan model pembelajaran Problem Based Learning pada
materi pencemaran lingkungan dapat meningkatkan hasil belajar peserta didik di SMP
Negeri 1 Blangjerango Kabupaten Gayo Lues.

Lisnawati. 2022. Application of Problem Based Learning Model for Improving Student Learning Outcomes on Environmental Pollution Materials At SMP Negeri 1 Blangjerango, Gayo Lues Regency. Thesis, Major Biology Education, Faculty of Teacher Training and Education, University Shia Kuala. Supervisor: (1) Dr. Muhibbuddin, M.Si. (2) Dr. Wiwit Artika, S.Si., M.Ed. Keywords: Learning Model, Student Learning Outcomes, Environmental Pollution The planned educational process is directed to create an atmosphere of learning and the learning process, in other words education should not override the learning process study. This study aims to determine the effect of the learning model Problem Based Learning on student learning outcomes on pollution material VII grade environment of SMP Negeri 1 Blangjerango for the 2020/2021 academic year. This study uses a quantitative approach. The instruments used are test items/multiple choice questions covering environmental pollution material. Population and the sample of this study were all students of class VII, amounting to 50 student. There are also data collection techniques in this study, namely (1) Data students' initial abilities were collected in the pretest activity, (2) Data students' final abilities (study outcomes) are collected by giving a final test in posttest activities. The data were analyzed, namely: (1) Tabulating the pretest score, the score posttest, and N-Gain scores, (2) Calculating pretest and posttest scores. (3) Counting the value of N-Gain, and (4) Test the hypothesis. The results of the study obtained the results of the t-test = 32.30 t table = 1.67 at a significant level of 0.05. Based on the results of these studies can concluded that the application of the Problem Based Learning learning model in environmental pollution materials can improve student learning outcomes in junior high school State 1 Blangjerango, Gayo Lues Regency.
