Model Mental Mahasiswa Pada Fenomena Penghilangan Karat Melalui Elektrolisis

Sunniarti Ariani, Effendy Effendy, Suharti Suharti

Abstract

Penelitian ini bertujuan untuk menggali model mental mahasiswa dalam memahami fenomena penghilangan karat melalui elektrolisis. Penelitian ini merupakan penelitian deskriptif dengan metode penelitian cross-section. Subyek penelitian adalah mahasiswa semester III dan V Program Studi Pendidikan Kimia FKIP Universitas Mataram yang dipilih dengan purposive sampling. Model mental mahasiswa digali menggunakan tes tertulis dan wawancara semistruktur. Model mental mahasiswa dianalisis menggunakan teknik constan comparative. Hasil penenlitian menunjukkan bahwa sebagian besar mahasiswa mengembangkan model mental inisial dalam memahami fenomena penghilangan karat melalui elektrolisis. Selain itu, ditemukan bahwa seiring dengan bertambahnya usia individu, model mental yang dikembangkannya mendekati model mental saintifik.

Kata Kunci: model mental, karat, elektrolisis.
