PENGEMBANGAN MEDIA PEMBELAJARAN KIMIA BERBASIS WEB: MENINGKATKAN LITERASI SISWA TENTANG LARUTAN ELEKTROLIT-NON ELEKTROLIT

DEVELOPMENT OF WEB-BASED CHEMISTRY LEARNING MEDIA: IMPROVING STUDENT LITERACY ABOUT ELECTROLYTE NON-ELECTROLYTE SOLUTIONS

Tujuan dilaksanakan penelitian untuk melihat kelayakan media pembelajaran yang menggunakan atau berbasis web untuk meningkatkan minat literasi siswa khususnya pada materi kimia yang berfokus pada larutan elektrolit dan non elektrolit. Peneliti menggunakan metode penelitian R&D (Research and Development). Peneliti juga memakai desain one group pretest and posttest dimana peneliti menggunakan 34 siswa XI MIPA 3 SMA Negeri 21 Surabaya sudah meneliti larutan kimia tersebut. Lembar telaah, lembar penilaian, angket respon, lembar validasi, pretest, serta posttest menjadi instrument penting dalam penelitian ini. Hasil telaah dalam penelitian ini, web sudah sesuai dan dapat diujicobakan. Tingkat kevalidan Web ini dalam segi konstruk mencapai 84%. Sementara dalam segi isi, tingkat kevalidan web ini dapat mencapai 84,16%. Media ini juga mencapai presentase 81,42% untuk respon menurut 28 murid yang sudah mencoba media web ini. Keberhasilan penelitian ini dilihat dari perbedaana antara posttest dan pretest peserta. Nilai posttest peserta mendapatkan nilai 73% sedangkan posttest mendapatkan nilai 100%.

The purpose of this research is to examine the feasibility of using web-based learning media to increase student literacy interest, especially in chemistry that focuses on electrolyte and non-electrolyte solutions. The researcher uses the R&D (Research and Development) research method. The researcher also used a one-group pretest and posttest design where the researcher used 34 students from XI MIPA 3 SMA Negeri 21 Surabaya who had examined the chemical solution. Study sheets, assessment sheets, response questionnaires, validation sheets, pretests, and posttests became important instruments in this research. The results of the study indicated that in this study, the web is appropriate and can be tested. The level of validity of this web in terms of constructs reaches 84%. Meanwhile, in terms of content, the level of validity of this website can reach 84.16%. This media also reached a percentage of 81.42% for responses according to 28 students who tried this web media. The success of this study was seen from the difference between the posttest and pretest participants. The posttest score of the participants got a score of 73%, while the posttest got a score of 100%.
