Berdasarkan hasil studi ditemukan kesalahan konsep (miskonsepsi) yang cenderung sama pada siswa dan mahasiswa, antara lain model konsumsi arus listrik dan baterai merupakan sumber arus listrik yang tetap. Tes pemahaman konsep diberikan kepada 30 siswa SMA dan 32 mahasiswa Prodi S1 Pendidikan Fisika yang berada di Kota Palangka Raya. Tes ini dikembangkan dari beberapa studi yang relevan. Instrumen penelitian yang digunakan dalam penelitian ini berupa tes pemahaman konsep dengan pilihan ganda beralasan terbuka disertai dengan certainty of response index (CRI). Tujuan dari studi ini adalah untuk memberikan gambaran mengenai pemahaman siswa di sekolah menengah (SMA) dan mahasiswa calon guru IPA (fisika) terhadap konsep dasar rangkaian listrik arus searah. Keywords: missconception, electric circuit, direct current, CRI.Ībstrak. The missconceptions on the direct current circuit that found in this study were also have been founded in some studies from other countries for various group of age and level of study. From the study result, it was found that the same of the kind of missconception problem tends to be found among the senior high school students and also the graduate students, for example is the concept of the consumption model of electric current and battery are the fixed current supply. The concept understanding test was given to 30 senior high school students and also 32 graduate students of physics education study program in Palangka Raya City. This test was developed from some relevant studies. The research instrument used in this study was the concept understanding test in the form of objective test that accompanied by certainty of response index (CRI). The purpose of this study is to describe the understanding of the direct current electric circuit basic concept that posses by senior high school students and natural science (physics) student teacher.
