Description This study aims to find out the misconceptions that occur in buffer solution materials using two-tier diagnostic tests instrument. The instrument was developed based on the buffer solution material competency indicators into 10 questions and was declared valid for use. The research was conducted on level I and III college students and students totaling 159. The results showed that there was a misconception on the concept of buffer solution properties of 24.6%, the concept of buffer solution composition was 24.1%, the working principle of buffer solution was 29.3 %, and the concept of pH solution is 25.4%. he cause of the misconception is because the initial concept of the respondent is weak, the teacher's explanation often simplifies the concept, the habit of the respondent to memorize, understanding the language and weak mathematical concepts, and learning models that have not provided the opportunity for respondents to understand the components and principles of working buffer solutions microscopically. Knowledge of misconceptions is needed as an evaluation of teachers and lecturers to be more motivated to implement learning models that are able to overcome misconceptions to prevent wider misconceptions in learning chemistry that make chemistry difficult.

Penelitian ini bertujuan mengetahui miskonsepsi yang terjadi pada materi larutan penyangga menggunakan instrumen soal two-tier diagnostic test . Instrumen dikembangkan berdasarkan indikator kompetensi materi larutan penyangga menjadi 10 pertanyaan dan dinyatakan valid untuk digunakan. Penelitian dilakukan terhadap siswa dan mahasiswa tingkat I dan III berjumlah 159. Hasil penelitian menunjukkan bahwa terjadi miskonsepsi pada konsep sifat larutan penyangga sebanyak 24,6%, konsep komposisi larutan penyangga sebanyak 24,1%, konsep prinsip kerja larutan penyangga sebanyak 29,3%, dan konsep pH larutan sebanyak 25,4%. Penyebab miskonsepsi dikarenakan konsep awal responden yang lemah, penjelasan guru yang sering menyederhanakan konsep, kebiasaan responden untuk menghafal, pemahaman bahasa dan konsep matematis yang lemah,  serta model pembelajaran yang belum memberikan kesempatan responden untuk memahami komponen dan prinsip kerja larutan penyangga secara mikroskopis. Pengetahuan tentang miskonsepsi diperlukan sebagai evaluasi terhadap guru dan dosen agar lebih termotivasi untuk menerapkan model pembelajaran yang mampu mengatasi miskonsepsi untuk mencegah timbulnya miskonsepsi lebih luas dalam pembelajaran kimia yang menjadikan kimia dianggap sulit.
