Abstract

Secara umum penelitian ini bertujuan untuk mengembangkan sebuah alat praktikum yang mampu mendeteksi gelembung gas pada suatu larutan. Jenis penelitian yang digunakan oleh peneliti adalah penelitian pengembangan yang mengacu pada model pengembangan 4-D yang memiliki 4 tahap yaitu Define, Design, Develop dan Desiminate. Peneliti menghasilkan sebuah media pembelajaran alat praktikum yang dapat mendeteksi gelembung udara pada larutan elektrolit yang dapat dibaca oleh gawai. Hasil validasi mengunakan rumus ‘Aiken diperoleh data sebesar 0,82 dengan kriteria kevalidan tinggi. Hasil uji kepraktisan peserta didik kelas X SMAN 1 Pulau Rimau diperoleh persentase sebesar 97,5 % dengan interpretasi sangat praktis. Hasil uji reabilitas menggunakan rumus Cornbach Alpha diperoleh nilai sebesar 0,75 dengan kriteria realibel.
