PENGARUH PENERAPAN MODEL PROBLEM BASED LEARNING (PBL) TERINTEGRASI SOCIO SCIENTIFIC ISSUES (SSI) PADA MATERI PERUBAHAN IKLIM UNTUK MENINGKATKAN LITERASI SAINS PESERTA DIDIK

THE EFFECT OF APPLICATION OF INTEGRATED SOCIO SCIENTIFIC ISSUES (SSI) PROBLEM BASED LEARNING (PBL) MODEL ON CLIMATE CHANGE MATERIALS TO IMPROVE STUDENT SCIENCE LITERACY

Penelitian ini bertujuan untuk meningkatkan kemampuan literasi sains peserta didik kelas X SMA dengan penerapan model Problem Based Learning (PBL) terintegrasi Socio Scientific Issues (SSI). Hasil penelitian berupa keterlaksanaan pembelajaran, kemampuan literasi sains peserta didik, dan respon peserta didik. Jenis penelitian yang digunakan adalah quasy experimental design dengan desain non-equivalent control group design. Subjek penelitian ini adalah peserta didik SMAN 1 Cerme, serta menggunakan dua kelas (X-1 dan X-2) yaitu satu kelas eksperimen pada kelas X-1 dan satu kelas kontrol pada kelas X-2 yang dipilih menggunakan teknik purposive sampling. Instrumen penelitian terdiri dari lembar observasi, lembar tes kemampuan literasi sains, dan lembar instrumen angket respon. Data yang telah terkumpul dianalisis secara deskriptif kuantitatif. Hasil penelitian menunjukkan penerapan model Problem Based Learning (PBL) terintegrasi Socio Scientific Issues (SSI) terlaksana dengan persentase rata-rata 93,81% dalam kriteria sangat baik. Pembelajaran model Problem Based Learning (PBL) terintegrasi Socio Scientific Issues (SSI) dapat meningkatkan kemampuan literasi sains peserta didik SMA yang ditunjukkan oleh 1) adanya peningkatan kemampuan literasi sains peserta didik secara statistik dengan signifikan pada , 2) hasil post-test lebih tinggi dari hasil pre-test dengan N-Gain 0,64 dengan kategori sedang, 3) hasil post-test kedua kelas memiliki perbedaan dengan t hitung pada uji-t dua pihak 4,79 dengan kesimpulan H0 ditolak, dan 4) hasil kemampuan literasi sains kelas eksperimen lebih baik dibandingkan hasil kemampuan literasi sains pada kelas kontrol ditandai dengan uji-t satu pihak H0 ditolak. Respon peserta didik terhadap pembelajaran untuk meningkatkan kemampuan literasi sains berdasarkan analisis angket respon diperoleh respon positif dengan persentase rata-rata baik sebesar 77,33% dengan kategori baik.

This study aims to improve the scientific literacy skills of class X high school students by implementing the integrated Socio Scientific Issues (SSI) Problem Based Learning (PBL) model. The results of the study were the implementation of learning, students' scientific literacy abilities, and students' responses. The type of research used is quasy experimental design with non-equivalent control group design. The subjects of this study were students of SMAN 1 Cerme, and used two classes (X-1 and X-2), namely one experimental class in class X-1 and one control class in class X-2 which were selected using a purposive sampling technique. The research instrument consisted of observation sheets, scientific literacy ability test sheets, and response questionnaire instrument sheets. The data that has been collected was analyzed descriptively quantitatively. The results showed that the implementation of the integrated Socio Scientific Issues (SSI) Problem Based Learning (PBL) model was carried out with an average percentage of 93.81% in very good criteria. Demonstrating the integrated Socio Scientific Issues (SSI) Problem Based Learning (PBL) learning model in improving the scientific literacy skills of high school students as indicated by 1) there is a statistically significant increase in students' scientific literacy skills at α=5%, 2) post results -test is higher than the pre-test results with N-Gain 0.64 in the medium category, 3) the results of the post-test of the two classes have a difference with t count on the two-party t-test 4.79 with the conclusion H0 is rejected, and 4) the results of scientific literacy skills in the experimental class were better than the results of scientific literacy abilities in the control class indicated by the one-party t-test H0 was rejected. Student responses to learning to improve scientific literacy skills based on response questionnaire analysis obtained positive responses with a good average percentage of 77.33% in the good category.
