UPAYA PENINGKATAN HASIL BELAJAR MATA PELAJARAN PDTO DENGAN PENGGUNAAN MODEL PEMBELAJARAN COOPERATIVE LEARNING TIPE GROUP INVESTIGATION (GI)

Penelitian ini bertujuan untuk mendeskripsikan peningkatan hasil belajar siswa dalam mata pelajaran Pekerjaan Dasar Teknik Otomotif (PDTO) dengan penggunaan model pembelajaran cooperative learning tipe group investigation pada kelas X TKR 1 di SMK Negeri 35 Jakarta. Jenis penelitian ini ialah Penelitian Tindakan Kelas (PTK). Penelitian Tindakan Kelas (PTK) meliputi kegiatan tiap siklus pada proses penelitiannya, dimana setiap siklus memiliki empat tahapan, yaitu perencanaan, tindakan, observasi, dan refleksi. Pada kegiatan proses pembelajaran menggunakan model pembelajaran cooperative learning tipe group investigation. Tempat penelitian di SMK Negeri 35 Jakarta, subyek penelitian ialah siswa kelas X TKR 1 dengan jumlah siswa 28 orang. Pengambilan data dilakukan pada tanggal 17 Oktober 2016 hingga tanggal 21 November 2016. Pengambilan data dilakukan dengan menggunakan catatan lapangan, lembar observasi guru dan siswa serta tes tiap siklus. Hasil penelitian dapat dilihat dari instrument hasil belajar siswa pada uji validitas, reliabilitas butir dan tes soal pilihan ganda yang terdapat peningkatan disetiap siklusnya, pada butir soal pada siklus I terdapat 4 soal yang tidak valid, sedangkan siklus II dan III telah mencapai valid, peningkatan yang sangat baik, dimana masing-masing butir tes soal telah melebihi daftar harga r tabel (25, 0,05) = 0,396. Berdasarkan hasil perhitungan reliabilitas pada siklus I maka telah didapatkan r = 0,650 yang dinyatakan reliabel, pada siklus II, r = 0,871 dan dapat dinyatakan reliabel, sedangkan pada siklus III, r = 0,567 dan dapat dinyatakan reliabel. Hasil penelitian yang diperoleh pada siklus I terdapat 12 siswa atau 48.00% mendapatkan nilai >75, pada siklus II terdapat 18 siswa atau 72.00% mendapatkan nilai >75, dapat disimpulkan pada siklus II terdapat peningkatan sebesar 24.00%, pada siklus III terdapat 23 siswa atau 92.00% mendapatkan nilai >75, dapat disimpulkan proses kegiatan belajar sudah mengarah pada model pembelajaran cooperative learning tipe group investigation (gi). Berdasarkan hasil analisis data terdapat peningkatan hasil belajar siswa dengan penggunaan model pembelajaran cooperative learning tipe group investigation, peningkatan dapat dilihat dari jumlah siswa yang mendapatkan nilai kriteria ketuntasan minimal (KKM) >75, pada siklus I terdapat 12 siswa atau 48.00%, pada siklus II terdapat 18 siswa atau 72.00%, dan pada siklus III terdapat 23 siswa atau 92.00%. This study aimed to describe the learning outcome of students in the subjects of Basic Works of Automotive Engineering (PDTO) using cooperative learning type group investigation on the class X TKR 1 in SMK Negeri 35 Jakarta. This type of research is the Action Research Classroom (PTK). Action Research Classroom (PTK) includes every cycle in the research process, where each cycle has four stages, namely planning, action, observation, and reflection. On the activities of the learning process using the learning model cooperative learning type group investigation. The place of research in SMK Negeri 35 Jakarta, the research subject is class X TKR 1 by the number of students 28 people. Data were collected on October 17, 2016 until November 21, 2016. Data were collected by using field notes, observation sheets teachers and students as well as tests of each cycle. The results of the study can be seen from the instrument student learning outcomes on the validity, reliability grains and test MCQs that there is an increase in every cycle, the items in the first cycle there are four questions that are not valid, whereas the cycle II and III have reached valid, improvement very good, where each item test questions have exceeded the price list r tables (25, 0,05) = 0.396. Based on the calculation of reliability in the first cycle it has obtained r = 0.650 were declared unreliable, the second cycle, r = 0.871 and can be expressed reliably, while the third cycle, r = 0.567 and can be expressed reliably. The results obtained in the first cycle there are 12 students or 48.00% gain value> 75, the second cycle, there are 18 students or 72.00% scores> 75, it can be concluded in the second cycle there is an increase of 24.00%, the third cycle there are 23 students or 92.00% scores> 75, we can conclude the process of learning has led to the teaching model of cooperative learning type group investigation (gi). Based on the results of data analysis are improving student learning outcomes with the use of learning model cooperative learning type group investigation, improvement can be seen from the number of students who scored a minimum completeness criteria (KKM)> 75, in the first cycle there are 12 students or 48.00%, in the second cycle there are 18 students or 72.00%, and the third cycle there are 23 students or 92.00%
