Penelitian ini bertujuan untuk menganalisis pengaruh model pembelajaran Problem Based Learning terhadap hasil belajar siswa pada Kompetensi Dasar Menerapkan Persiapan Penyelenggaraan Pertemuan/Rapat Kelas XI OTKP di SMKN 1 Bangkalan serta mendeskripsikan penerapan pembelajaran Problem Based Learning pada Kompetensi Dasar Menerapkan Persiapan Penyelenggaraan Pertemuan/Rapat Kelas XI OTKP di SMKN 1 Bangkalan. Populasi dan sampel dalam penelitian ini adalah seluruh siswa kelas XI OTKP 1 dan kelas XI OTKP 3, dimana kelas XI OTKP 1 sebagai kelas kontrol dan Kelas XI OTKP 3 sebagai kelas eksperimen. Instrumen penelitian yang digunakan adalah perangkat pembelajaran dan lembar tes. Metode pengumupulan data menggunakan hasil belajar siswa. Teknik analisis data menggunakan uji normalitas, uji homogenitas, uji t (hipotesis).

Hasil penelitian ini menunjukkan bahwa ketuntasan hasil belajar siswa pada kelas eksperimen dinyatakan tuntas 100% secara klasikal, sedangkan kelas kontrol dinyatakan tuntas 85% secara klasikal. Nilai rata-rata posttest pada kelas eksperimen sebesar 82,60, sedangkan pada kelas kontrol sebesar 78,30. Selisih nilai rata-rata pretest dan posttest pada kelas eksperimen sebesar 23,10 dan pada  kelas kontrol sebesar 12,67.

Berdasarkan hasil analisis uji t nilai posttest, diperoleh sebesar 4,353 dengan taraf singinfikan sebesar ,000 (0,000). Sedangkan t_tabel diketahui sebesar 2,002. Sehingga dapat disimpulkan bahwa Ho diterima karena t-test < 0,05  yaitu 0,000 < 0,05 dan t_hitung (4,353) > t_tabel (2,002). Serta, penerapan model Problem Based Learning terhadap hasil belajar siswa kenaikan secara signifikan.   Diketahui bahwa  nilai rerata berpikir kritis serupa dibantu soal studi kasus sebesar 86,75. Artinya, dengan model Problem Based Learning berhasil memberanikan siswa mengutarakan pendapat atau gagasan tersebut. Dengan demikan, dapat disimpulkan bahwa terdapat pengaruh model pembelajaran Problem Based Learning terhadap hasil belajar siswa pada kompetensi dasar menerapkan persiapan penyelenggaraan pertemuan/rapat kelas XI OTKP di SMKN 1 Bangkalan, dimana hasil belajar siswa yang menggunakan model pembelajaran problem based learning lebih tinggi daripada hasil belajar kelas kontrol.

This study aims to analyze the effect of Problem Based Learning learning models on student learning outcomes in Basic Competency Implementation Arrangements for Class XI OTKP Meetings in Bangkalan Vocational High School 1 and describing the application of Problem Based Learning to Basic Competencies Implementing Preparation of Class XI OTKP Meeting in SMKN 1 Bangkalan. The population and sample in this study were all students of class XI OTKP 1 and class XI OTKP 3, where class XI OTKP 1 as a control class and Class XI OTKP 3 as an experimental class. The research instruments used were learning devices and test sheets. The method of collecting data uses student learning outcomes. Data analysis techniques using the normality test, homogeneity test, t-test (hypothesis).

The results of this study indicate that the completeness of student learning outcomes in the experimental class was declared 100% complete in a classical manner, while the control class was declared complete 85% in a classical manner. The posttest means value in the experimental class was 82.60, while in the control class it was 78.30. The difference in the average value of the pretest and posttest in the experimental class was 23.10 and the control class was 12.67.

Based on the results of the t-test analysis, the posttest value was obtained at 4,353 with a significance level of 000 (0,000). While the table is known at 2.002. So it can be concluded that Ho is accepted because the t-test <0.05 is 0,000 <0,05 and count (4,353)> table (2,002). And, the application of the Problem Based Learning model to student learning outcomes increases significantly. It is known that similar critical thinking averages assisted by case study questions amounted to 86.75. That is, the Problem Based Learning model successfully encourages students to express their opinions or ideas. Thus, it can be concluded that there is the effect of the Problem Based Learning learning model on student learning outcomes on basic competencies applying the preparation for the implementation of OTKP class XI meetings  in SMKN 1 Bangkalan, where student learning outcomes using problem-based learning models are higher than learning outcomes control class.
