Pendidikan kejuruan di Indonesia telah menerapkan kurikulum 2013 dalam mana siswa dituntut aktif dalam proses pembelajaran. Namun di SMK Negeri 1 Jatirejo masih dijumpai beberapa kekurangan yang menyebabkan 69,7 % hasil belajar siswa di bawah KKM. Penyebabnya antara lain karena proses pembelajaran yang belum efektif sehingga respon siswa selama pelajaran cenderung pasif. Penelitian ini bertujuan untuk meningkatkan kualitas pembelajaran dari segi efektivitas pembelajaran, respon siswa selama proses pembelajaran dan hasil belajar siswa dapat di atas KKM. Penelitian dilaksanakan di kelas 10 TMI di SMK Negeri 1 Jatirejo pada mata pelajaran Dasar Perancangan Teknik Mesin dengan menerapkan model pembelajaran kooperatif Student Team Achievement Divisions (STAD) berbantuan media Adobe Flash Professional CS6.

                Metode yang digunakan pada penilitian ini adalah Penelitian Tindakan Kelas (PTK) dengan alur penilitian sikluistik dari Mc Taggart yaitu perencanaan, tindakan, pengamatan, dan refleksi. Teknik pengumpulan data untuk efektivitas pembelajaran mengggunakan lembar pedoman observasi, untuk respon siswa menggunakan angket, dan untuk hasil belajar berupa tes. Pengumpulan data yang dilakukan dapat mengetahui ketercapaian dari target penelitian.

                Hasil penelitian menunjukkan bahwa terdapat dua siklus untuk dapat mencapai target penelitian. Efektivitas pembelajaran di siklus I mendapatkan hasil sebesar 75,46% dan meningkat di siklus II sebesar 87,57% dengan kategori sangat efektif, respon siswa pada siklus I menunjukkan hasil sebesar 77,40% dan meningkat di siklus II sebesar 83,70% dengan kategori sangat baik, hasil belajar siswa pada siklus I ketuntasan klasikal sebesar 63,64% atau hanya 21 anak dari 33 siswa hasil belajarnya tuntas, meningkat di siklus II menunjukkan 84,85% atau 28 siswa hasil belajarnya tuntas.

Vocational education in Indonesia has implemented the 2013’s curriculum that students are required to be active in the learning process. However, at SMK Negeri 1 Jatirejo there are still some shortcomings that cause 69.7% of student learning results under the KKM. The reasons for this are because the learning process has not been effective so the student’s responses during the lesson tend to be passive. This study aims to improve the quality of learning in terms of learning effectiveness, student responses during the learning process and student learning results can be above the KKM. The research was conducted in the 10th class of TMI at State Vocational School of 1 Jatirejo in the Basic Mechanical Engineering Design subjects by applying the Student Team Achievement Division (STAD) cooperative learning model assisted by Adobe Flash Professional CS6.

                The method used in this research is Classroom Action Research (CAR) with the cyclical research flow of Mc Taggart tht is planning, action, observation, and reflection. Data collection techniques for learning effectiveness use the observation guideline sheet, for students' responses to using questionnaires, and for learning results use the form of tests. Data collection can find out the achievements of the research targets.

The results of the research show that there are two cycles to be able to reach the research target. The effectiveness of learning in cycle I gets results of 75.46% and increases in cycle II by 87.57% with the category of very effective, the response of students in the first cycle shows results of 77.40% and increases in the second cycle of 83.70% with the category is very good, student learning outcomes in the first cycle of classical completeness is 63.64% or only 21 children of 33 students the results of their study are complete, increasing in the second cycle shows 84.85% or 28 students the learning results are complete.
