this study aims to determine the level of misconceptions in class XI students of SMA Negeri 3 Poso using a quantitative descriptive approach to the buffer solution material during the covid-19 pandemic. The subject of this research consisted of 36 students. The sampling technique was simple random sampling. The research instrument used was a three-tier multiple choice diagnostic test (Three-tier) with a total of 10 questions. Based on the results of research and data analysis showed that the percentage of understanding concepts as much as 23.33%, students' misconceptions as much as 42.78%, and not understanding concepts as much as 33.89%. Based on the results of the percentage of students who experienced misconceptions (False Positive) as many as 11.39%, misconceptions (False Negative) as many as 11.11%, misconceptions as much as 20.28%. Misconceptions still occur in each indicator in the buffer solution material, where the highest misconception is in item number 8 with an indicator for determining the characteristics of a buffer solution in an acid or alkaline state with a percentage of 50%, item numbers 9 and 10 with an indicator explaining how to make a solution. buffer with each percentage of 47.22%. The lack of students' understanding of the buffer solution material is the main factor causing misconceptions, coupled with the pandemic situation which requires students to study more independently, causing limited communication between teachers and students. Thus, the results in the category of misconceptions of SMA Negeri 3 Poso students are in the medium category. The results of this study are expected to be a source of information as well as a motivation and reference for teachers and students to be able to understand chemistry better so as to minimize the occurrence of misconceptions in students.
