ABSTRAK
Penelitian ini bertujuan untuk: 1) Mengembangkan model JiTT berbasis pendekatan saintifik, 2) Mengetahui kelayakan model JiTT berbasis pendekatan saintifik, 3) Mengetahui keefektivitasanmodel JiTT berbasis pendekatan saintifik untuk meningkatkan kemampuan berpikir analitis kelas X SMA pada materi jamur.
Penelitian ini menggunakan metode Research and Development (R & D) mengacu pada model Borg & Gall (1983) dengan tahapan: 1) penelitian dan pengumpulan informasi, 2) perencanaan, 3) pengembangan produk awal, 4) uji coba permulaan, 5) revisi produk pertama, 6) uji lapangan terbatas, 7) revisi produk kedua, 8) uji lapangan operasional, 9) revisi produk ketiga, 10) disseminasi. Kelayakan model divalidasi oleh ahli model, ahli materi, guru biologi (praktisi), dan siswa. Pengumpulan data dilakukan dengan menggunakan angket, lembar observasi, wawancara, dan tes. Data penelitian dianalisis dengan metode deskriptif kualitatif dan deskriptif kuantitatif. Kemampuan belajar analitis dianalisis dengan mengunakan uji t (t test) dengan desain posttest only control group design.
Berdasarkan hasil penelitian dapat disimpulkan sebagai berikut: 1) pengembangan model pembelajaran JiTT berbasis saintifik dilakukan dengan memperhatikan karakteristik dari model yaitu adanya sintaks, sistem sosial, sistem pendukung, peran siswa, peran guru, dampak intruksional, dan dampak pengiring, 2) hasil pengembangan model pembelajaran JiTT berbasis saintifik layak untuk diterapkan pada materi jamur. Kelayakan model pembelajaran JiTT berbasis saintifik berdasarkan penilaian dari ahli, praktisi, dan respon siswa yang secara keseluruhan memberikan kategori baik pada produk pengembangan, 3) model pembelajaran JiTT berbasis saintifik mampu meningkatkan kemampuan berpikir analitis siswa. Uji statistik pada kemampuan berpikir analitis menunjukkan ada perbedaan yang signifikan (sig 0,00 < 0,05) antara kelas kontrol dan kelas eksperimen.
Kata kunci: Model pembelajaran JiTT, pendekatan saintifik, kemampuan berpikir analitis, materi jamur.
ABSTRACT
This research aimed: 1)  To develop JiTT model with saintific approach, 2) to examine the feasibility of  JiTT model with saintific approach, 3) To examine the effectiveness of  JiTT model with saintific approach to empower analytical thinking in eleventh grade student of  SMA.
This research employed a research and development (R&D) referring to Borg & Gall (1983) encompassing research and information collection, planning, developing preliminary form of product, preliminary field test, main product revision, main field testing, operasional product revision, operasional field testing and final product revision stage. The feasibility of model was validated by the model expert, material expert,  and biological teachers (practitioner) and students. The data collection was conducted using questionnare, observation sheet, and test. Data result analyzed by descriptive qualitative method with the and quantitative method. The data analythic thinking outcome using t-test with posttest only control group design.
Considering the result of research, the following conclusions could be drawn: 1) The development of JiTT with saintific approach at mushroom matter perfomed by taking into account the characteristics of the model that is the syntax, social systems, support systems, student role, teachers role, instructional effects, and nurturant effects, 2) The development of JiTT with saintific approach at mushroom matter was feasible to support the learning in such the matter. The feasibility of JiTT with saintific approach, based on the assesment from expert, practitioner and student response, overall, provided good and very good category in development product and it was feasible to be used, 3) JiTT with saintific approach could improve the student’s learning outcomes. It could be seen from the  statistic test on analytic outcome provided a significant difference (sig 0,00 < 0,05) with the score of field trial higher than that of baseline class.
Keywords: JiTT, saintific approach, analytical thinking, mushroom matter.
