Abstract
One of the factors of the low ability of students' mathematical problem solving is because students think that mathematics is a difficult subject. After all, mathematics requires accuracy in calculations. The purpose of the study was to determine the types of students' mistakes in problem-solving based on Newman's theoretical procedures and to find out why students made these mistakes. The research method used is qualitative. The research subjects were 4 grade VIII students for the 2020/2021 academic year at Kp Cilengkeng Ds Wangunjaya, Banjarwangi District. The data collection techniques used observation, test questions, and interviews, while the data analysis techniques used the Milles and Huberman model. The results showed that students made mistakes only at the stage of understanding the problem as much as 31.25%, while at the stage of process skills as much as 50% and at the stage of writing the final answer as much as 12.50%. The factors that cause students to do this are not being able to understand the questions well, not being familiar with the questions given by the researcher, not being able to transform their language sentences to compile steps to make a line diagram, not taking good time, not being careful, hurry and not. can conclude a problem using their language sentences.
