PENGEMBANGAN MODEL PEMBELAJARAN KOOPERATIF BERBASIS KEARIFAN LOKAL MASYARAKAT ADAT BADUY LUAR UNTUK MENINGKATKAN KARAKTER KERJA SAMA SISWA SEKOLAH DASAR

Penelitian ini dilatar belakangi hasil studi pendahuluan yakni tidak tercapainya tujuan pembelajaran kooperatif yaitu keterampilan sosial berupa kerja sama sebagai karakter yang baik di sekolah dasar Kecamatan Cikulur, Kabupaten Lebak karena adanya hambatan siswa sebagai pembonceng dalam tugas kelompok sehingga difusi tanggung jawab tidak terjadi sehingga proses pembelajaran kerja sama masih terfokus pada hasil bukan pada proses membangun karakter kerja sama. Hasil studi pendahuluan selanjutnya diketahui bahwa Rereongan sebagai kearifan Lokal Masyarakat Adat Baduy Luar memiliki empat prinsip dasar kerja sama yang secara turun temurun dan berabad-abad lamanya berhasil menginternalisasikan nilai kerja sama pada generasi Masyarakat Adat Baduy Luar, menilik fakta tersebut perlu pembuktian melalui penelitian pengembangan model Pembelajaran Kooperatif Berbasis Kearifan Lokal Masyarakat Adat Baduy Luar untuk Meningkatkan Karakter Kerja sama Siswa Sekolah Dasar. Penelitian menggunakan metode Penelitian Pengembangan Research and Development (R and D) dengan desain eksperimen. Uji coba terbatas dilakukan dengan menggunakan rancangan pre-experiment pada satu rombongan belajar melibatkan 21 siswa sekolah dasar, sedangkan uji coba lebih luas dilakukan pada satu rombongan belajar melibatkan 22 siswa, selanjutnya uji coba penerapan pada enam rombongan belajar melibatkan 151 siswa. Instrumen pengumpulan data menggunakan lembar observasi, angket, wawancara dan lembar validasi serta tes hasil belajar kognitif. Hasil penelitian pengembangan ini merupakan model Pembelajaran Kooperatif Berbasis Kearifan Lokal Masyarakat Adat Baduy Luar (PKBKL-MABL) yang valid dan efektif dalam meningkatkan karakter kerja sama siswa sekolah dasar, melalui tahap pengujian efektifitas model diperoleh hasil uji t pada karakter kerja sama sebesar 4.521 lebih besar dari pada uji t table yaitu 1,684 sehingga membuktikan adanya perbedaan yang signifikan peningkatan karakter kerja sama antara siswa yang diberkan perlakuan Model Pembelajaran Kooperatif Berbasis Kearifan Lokal Masyarakat Adat Baduy Luar (PKBKL-MABL) dengan siswa yang menggunakan model Pembelajaran Kooperatif, dengan demikian model PKBKL-MABL efektif dalam meningkatkan karakter kerja sama siswa sekolah dasar. Selanjutnya hasil belajar (kognitif) siswa sebagai dampak iringan model PKBKL-MABL pada kelas eksperimen mengalami peningkatan nilai N Gain secara signifikan jika dibandingkan dengan kelas kontrol, berdasarkan Uji t pada hasil belajar (kognitif) siswa sebesar 4,612 lebih besar daripada t tabel yaitu 1,684 sehingga membuktikan adanya perbedaan yang signifikan peningkatan hasil belajar (kognitif) melalui penerapan model PKBKL-MABL pada kelas eksperimen dibandingkan hasil belajar (kognitif) melalui penerapan model Pembelajaran Kooperatif.----------This research is motivated by a preliminary study namely the importance of the character of cooperation as an educational goal that has not been achieved in elementary schools in Cikulur District, Lebak Regency through the application of the Cooperative Learning model due to students' obstacles as pillion in group assignments so that the diffusion of responsibility does not occur as an indication in the process cooperative learning is still focused on results not on the process of building the character of cooperation. The results of the preliminary study further revealed that Rereongan as Local Wisdom of the Outer Baduy Indigenous Peoples has four basic principles of cooperation that for generations and for centuries succeeded in internalizing the value of cooperation in the generations of the Outer Baduy Indigenous Peoples, judging this fact need proofing through research development models Cooperative Learning Based on Local Wisdom of Outer Baduy Indigenous Peoples to Improve the Characters of Primary School Student Cooperation. Research uses the Research Development and Research (R and D) method with an experimental design. Limited trials were conducted using a pre-experiment design on a study group involving 21 elementary school students, while a wider trial was conducted on a study group involving 22 students, then the trial implementation on six study groups involved 151 students. Data collection instruments used observation sheets, questionnaires, interviews and validation sheets as well as cognitive learning test results. The results of this development research are Cooperative Learning models based on Local Wisdom of the Outer Baduy Indigenous Peoples (CL-BKL-MABL) which are valid and effective in improving the cooperation character of elementary school students, through the testing stage the effectiveness of the model obtained the results of t test on the cooperation character of 4,521 greater than the t table test of 1.684 so as to prove a significant difference in the character of cooperation between students who were given the treatment of Cooperative Learning Model Based on Local Wisdom of the Outer Baduy Indigenous Peoples (CLBKL-MABL) with students using the Cooperative Learning model, thus the model CLBKL-MABL is effective in improving the cooperation character of elementary school students. Furthermore, student learning outcomes (cognitive) as a result of the accompaniment of CLBKL-MABL models in the experimental class significantly increased the N Gain value when compared with the control class, based on the t test on student learning outcomes (cognitive) of 4,612 is greater than the t table test of 1,684 thus proving a significant difference in the improvement of learning outcomes (cognitive) through the application of CLBKL-MABL models in the experimental class compared to learning outcomes (cognitive) through the application of Cooperative Learning models
