PENGEMBANGAN MODUL CNC MACH3 TURN UNTUK MENINGKATKAN MOTIVASI DAN HASIL BELAJAR SISWA DI KELAS XII  JURUSAN TEKNIK PEMESINAN SMK KRIAN 1 SIDOARJO

CNC MACH3 TURN MODULE DEVELOPMENT TO IMPROVE THE MOTIVATION AND LEARNING OUTCOMES OF STUDENTS IN CLASS XII OF MECHANICAL ENGINEERING DEPARTMENT SMK KRIAN 1 SIDOARJO

Mesin CNC yang telah diterapkan di SMK Krian 1 Sidoarjo merupakan mesin Computer Numerically Controlled (CNC) yang bertipe CNC TU 2A (CNC bubut). Pada pembelajaran CNC TU 2A dirasa kurang efektif karena pemrogramannya masih menyulitkan peserta didik dan memakan waktu yang lama. Modul mesin CNC sebagai media belajar siswa masih belum ada. Maka dari itu perlu dikembangkan modul untuk membantu proses belajar siswa. Selain itu berdasarkan observasi yang dilakukan hasil belajar dan motivasi belajar siswa pada pembelajaran CNC selama ini dirasa masih rendah. Tujuan penelitian ini adalah (1) Mengetahui tingkat kelayakan modul CNC mach3 turn. (2) Mengetahui hasil belajar siswa setelah mendapatkan pembelajaran CNC mach3  turn. (3) Mengetahui motivasi belajar siswa setelah mendapatkan pembelajaran CNC mach3 turn.

Jenis penelitian yang digunakan merupakan jenis penelitian pengembangan yaitu Research and Development (R & D).  Namun pada pengembangan modulnya akan digunakan model pengembangan 4D (define, design, develope, dan disseminate) yang telah dikembangkan oleh S. Thiagarajan, Dorothy S, Semmel, dan Melvyn I. Semmel. Teknik pengambilan sampel yang digunakan adalah simple random sampling. Skala pengukuran yang digunakan pada instrumen penelitian adalah skala likert. Teknik analisis data dalam penelitian ini menggunakan statistik deskriptif.

Berdasarkan penelitian yang telah dilakukan, diperoleh tingkat kelayakan modul CNC Mach3 turn rata-rata dari seluruh validasi memperoleh kriteria valid, sehingga modul layak untuk digunakan. Tingkat motivasi belajar siswa diperoleh kriteria baik dengan rata-rata persentase sebesar 75%. Hasil  pre test diperoleh sebanyak 24 siswa belum tuntas dan 6 siswa dikatakan tuntas, sedangkan hasil   post test diperoleh sejumlah 9 siswa belum tuntas dan 21 siswa dikatakan tuntas. Dengan demikian terjadi peningkatan hasil belajar siswa setelah siswa mendapatkan pembelajaran dengan modul CNC Mach3 turn.

               The CNC machine that has been implemented at SMK Krian 1 Sidoarjo is a Computer Numerically Controlled (CNC) machine with the type of CNC TU 2A (CNC lathe). In learning CNC TU 2A it is considered less effective because the programming is still difficult for students and takes a long time. The CNC machine module as a student learning media does not yet exist. Therefore it is necessary to develop a module to help the student learning process. In addition, based on observations made, learning outcomes and student learning motivation in CNC learning so far are still low. The objectives of this study are (1) to determine the feasibility level of the CNC mach3 turn module. (2) Knowing student learning outcomes after getting CNC mach3 turn learning. (3) Knowing the students' learning motivation after getting the CNC mach3 turn learning.

                The type of research used is a type of development research, namely Research and Development (R & D). However, the module development will use the 4D development model (define, design, develop, and disseminate) which has been developed by S. Thiagarajan, Dorothy S, Semmel, and Melvyn I. Semmel. The sampling technique used is simple random sampling. The measurement scale used in the research instrument is the Likert scale. The data analysis technique in this study used descriptive statistics.

                Based on the research that has been done, it was found that the average level of the CNC Mach3 turn module feasibility from all validations obtained valid criteria, so that the module was feasible to use. The level of student learning motivation obtained good criteria with an average percentage of 75%. The results of the pre test were obtained as many as 24 students who had not completed and 6 students were said to be complete, while the results of the post test were obtained that a number of 9 students had not completed and 21 students were said to be complete. Thus there is an increase in student learning outcomes after students get learning with the CNC Mach3 turn module.
