The research subjects consisted of 89 students who programmed the Introduction to Basic Mathematics (PDM) course. The research method used is qualitative descriptive. A written test consisting of 4 reasoned multiple choice and descriptive questions were used to collect research data. The results showed that based on CRI criteria, for problem number 1 about the differences of set and not sets, there were 39% of students experiencing misconceptions, 33% of students do not know the concept and 28% of students who know the concept correctly. In question number 2, the questions about three ways of presenting a set of natural, whole, prime and integers numbers, it was found that 12% of students experienced misconceptions and 76% of students did not know the concept because of guessing and lack of knowledge, the remaining 11% of students understand the concept very well. For problem number 3, about the operation of the set found that 30% of students experienced misconceptions, 45% did not know the concept and the remaining 24% understood the concept correctly. Furthermore, for problem number 4, the set operation story was obtained the result that of 19% of students who took the test experienced misconceptions, 57% of students did not understand the concept and only 24% of students understood the concept correctly. In other words, of the 4 questions that were tested on students, questions number 1 and 3 were mostly found by students experiencing misconceptions. Although problem number 2, it was found that at least students experienced misconspection but in this questions almost 80% of students did not know the concept correctly ER -
