DEVELOPMENT OF CHEMORROSION INTERACTIVE MULTIMEDIA IN CORROSION TOPIC THIRD GRADE OF SENIOR HIGH SCHOOL

Abstract

Tujuan penelitian ini adalah untuk mengetahui kelayakanmultimedia interaktif,dan pergeseran konsepsi siswa padamateri korosi kelas XII SMA. Metodepenelitian yang digunakan adalah metode Research & Development (R & D). Instrumen penelitian yang digunakan adalah lembar validasi media, lembar angket respon siswa, dan lembar tes hasil belajar siswa dengan menggunakan Certainty of Response Index (CRI). Sumber data diperoleh dari dosen kimia dan guru kimia, serta 15 siswa SMA Kelas XII.Berdasarkan hasil penelitian, rata-rata persentase penilaian dosen kimia dan guru kimia terhadap kelayakan multimedia interaktif Chemorrosionadalah 88,27% dengan kategori sangat layak, sedangkan respon siswa terhadap kelayakan multimedia interaktif Chemorrosion adalah 97,51% dengan kategori sangat layak. Selain itu, hasil penelitian menunjukkan adanya pengaruh multimedia interaktif Chemorrosion terhadap perubahan konsepsi siswa, yaitu peningkatan persentase siswa yang tahu konsep sebesar 66,11%, penurunan persentase siswayang tidak tahu konsep sebesar 50,28%, dan penurunan persentase siswa yang mengalami miskonsepsi sebesar 15,84%.

The purpose of this research  to determine the feasibility of interactive multimedia, and shifting conceptions of students in corrosion topic third gradesenior high school. The method which was used is  Research & Development (R & D). Instruments which was used in this research is media validation sheet, student responses questionnaire sheet, and student test sheet using Certainty of Response Index (CRI). Sources of data was obtained from the lecturerand teacher of chemistry, 15 students oh third grade.  Based on the research, the average percentage of lecturer and teacher chemistry assessment of the feasibility of interactive multimedia Chemorrosion was 88.27% very feasible category, while the students' response to the feasibility of interactive multimedia Chemorrosion was 97.51% very feasible category. Moreover, the results showed the influence of interactive multimedia Chemorrosion on students' conceptions shifting, namely increase in the percentage of students who know the concept of 66.11%, a decrease in the percentage of students who did not know the concept of 50.28%, and the decreae in percentage of students who have misconceptions of 15.84%.
