Penelitian eksperimen ini bertujuan untuk mengetahui pengaruh model pembelajaran problem based learning terhadap hasil belajar siswa pada kompetensi dasar menerapkan tata ruang kerja/kantor di kelas X OTKP SMK Negeri 4 Surabaya pada tahun ajaran 2019/2020. Bentuk penelitian yang digunakan adalah quasy exsperimental design dengan model nonequivalent control group design. Subjek penelitian sebanyak 70 siswa dari kelas X OTKP 2 dan X OTKP 3. Instrumen dalam penelitian ini berupa penilaian kognitif yang diukur menggunakan pretest dan posttest, penilaian tugas dari penggunan model pembelajaran problem based learning yang berupa tugas individu untuk mengukur hasil belajar pada ranah psikomotor. Teknik analisis data yang digunakan yaitu analisi butir soal yang berupa uji validitas, uji reliabilitas, uji daya beda dan uji tingkat kesukaran. Kemudian terdapat uji normalitas, uji homogenitas dan uji gain score.  Hasil penelitian menunjukkan bahwa taraf signifikasi sebesar ,034 (0,034) dengan t_hitung 2,163 dan df sebesar 68, sehingga t_tabel diperoleh sebesar 1,995. Dapat diartikan bahwa H_a diterima dan H₀ ditolak, dikarenakan t-test < 0,05 yaitu 0,034 < 0,05 dan t_hitung (2,163) > t_tabel (1,995). Sehingga terdapat pengaruh model problem based learning terhadap hasil belajar siswa kelas X OTKP di SMK Negeri 4 Surabaya.

Kata Kunci: Model Pembelajaran Problem Based Learning, Hasil Belajar.

This experimental study aims to determine the effect of problem based learning model on student learning outcomes on the basic competencies of implementing work/office layout in grade X OTKP Vocational High School 4 Surabaya in 2019/2020. The form of research used was quasy experimental design with a nonequivalent control group design model. The research subjects were 70 students from grade X OTKP 2 adnd X OTKP 3. The instruments in this study were cognitive assessment which was measured using pretest and posttest, the assessment of the task of using problem based learning model in the form of individual assignments to measure the results learning in the psychomotor sector. The data analysis technique used is item analysis in the form of validity test, reliability test, different power test and difficulty level test. Then there is the normality test, homogeneity test and gain score etst. The results showed that the level of significance was ,034 (0,034) with a t_count of (2,163) and a df of 68, so the t_table was obtained for 1,995. It can be interpreted that H_a is accepted and H₀ is rejected, because t-test < 0,05 is (0,034) < (0,05) and t_count (2,163) > t_table (1,995). So there is the influence of the problem based learning model on student learning outcomes in grade X OTKP at Vocational High School 4 Surabaya.
