PENGEMBANGAN MULTIMEDIA INTERAKTIF ELECTROLYSIS MULTIMEDIA PADA POKOK BAHASAN SEL ELEKTROLISIS SEBAGAI MEDIA PEMBELAJARAN DI KELAS XII SMA

Abstract

Penelitian ini bertujuan untuk mengetahui kelayakan multimedia interaktif Electrolysis Multimedia sebagai media pembelajaran pada materi pokok sel elektrolisis, serta untuk mengetahui pengaruh multimedia interaktif terhadap hasil belajar siswa. Metode penelitian yang digunakan adalah metode Research and Development (R&D) yang terdiri dari: 1) tahap studi pendahuluan yang meliputi potensi, masalah, dan pengumpulan data; 2) tahap studi pengembangan yang meliputi proses desain produk, validasi produk, revisi produk, dan uji coba produk. Instrumen penelitian yang digunakan adalah lembar telaah, lembar validasi, lembar angket respon siswa, dan lembar tes hasil belajar siswa dengan menggunakan Certainty of Response Index (CRI). Sumber data diperoleh dari dosen dan guru kimia, serta 15 siswa SMA Kelas XII. Teknik pengumpulan data dengan mengunakan angket dan lembar hasil belajar. Data yang diperoleh dari hasil penelitian, kemudian diolah dengan menggunakan teknik analisis deskriptif kuantitatif. Berdasarkan hasil penelitian yang telah dianalisis, rata-rata persentase penilaian dosen kimia dan guru kimia terhadap kelayakan Electrolysis Multimedia adalah 90,20%, sedangkan respon siswa terhadap kelayakan Electrolysis Multimedia adalah 97,51%. Selain itu, hasil penelitian menunjukkan adanya pengaruh Electrolysis Multimedia terhadap hasil belajar siswa khususnya pada perubahan konsepsi, yaitu peningkatan persentase siswa yang tahu konsep dari 4,16% menjadi 76,65%, penurunan persentase siswa yang mengalami miskonsepsi dari 58,63% menjadi 12,8%, dan persentase siswa yang tidak tahu konsep dari 37,22% menjadi 10,55%. Sesuai dengan hasil penelitian tersebut, Electrolysis Multimedia dapat disimpulkan sebagai media pembelajaran yang layak digunakan dan dapat membantu siswa dalam memahami materi sel elektrolisis.

This study aims to determine the feasibility of interactive multimedia,named as multimedia electrolysis, to be a learning media in the subject of elecytrolysis cell, and also to assess the effect of interactive multimedia on the student’s learning process. The research method was based on the concept of research and development (R & D) that consist of: 1) the preliminary study that covers the assessment of potential and problem as well as collecting the data; 2) the development study that involve the product design, product validation, product revision, and the trial test. The research instruments were consisted of reviewer sheet, validation sheet, student’s response sheet and tests student learning outcomes, those instruments were based on the concept of certainty of response index (CRI). Sources of data were obtained from the lecturer and the teacher in chemistry as well as 15 senior high school students at grade XII. The data were collected by using questionnaire and student’s paper result. Then the data was analyzed by the analysis technique of quantitative descriptive. According to the results, the average value of assessment test by the lecturer and the teacher in chemistry was at 90,20%, while the students’ response to the feasibility of the electrolysis multimedia was at 97,51%. Furthermore, the research revealed that there are some positive effect of the electrolysis multimedia into the student’s learning process, in particular to the change in students’ conceptions including an increase in the number of students who understand the concept from 4,16% to 76,65% and also a decrease in the number of students who have misconceptions from 58,63% to 12,8% as well as the student who does not know the concept from 37,22% to 10,55%. In conclusion, the electrolysis multimedia could be used as a promising media that is useful on the student learning process to understand the concept of electrolysis cell.
