Abstract:The study was conducted to analyze student errors in the statistical problem-solving process using Newman in terms of metacognitive tacit use. The research method used is qualitative method. Data analysis used is the analysis of the results of the test, questionnaire analysis and analysis of interview transcripts. Based on the results of the study, it was concluded that the subjects of tacit use metacognitive categories did not know their weaknesses in the learning process, gave inconsistent answers, had little confidence, focused only on answers and not on the process. Subjects with tacit use metacognitive categories made mistakes in solving statistical problems almost at all stages of Newman. Newman's error analysis consists of reading errors, comprehension errors, transformation errors, process skills errors, encoding errors. The subject is wrong in interpreting the symbol, the subject cannot determine what is known and asked about the question, the subject does not write detailed calculation steps, and the subject cannot conclude the final answer to the problem solving. Errors in completing the test questions occur because the subject does not re-check the answers given in the problem.

Abstract:The purpose of this study is to analyze mathematical problem-solving abilities based on Polya's steps and the causes of students' errors in solving mathematical problems. The problem-solving stage consists of 4 stages, namely the stage of understanding the problem, planning a solution, carrying out a solution plan, and looking back. This study used 6 subjects from 25 eighth grade students of SMP Terpadu Turen. Data collection is done by tests and interviews. Data validity test is done by triangulation technique. The results of this study were (1) at the stage of understanding many students, they did not experience difficulties because students were able to understand the problem, (2) at the planning stage there were some students who did not write the completion plan but understood the way they would do to solve the problem but they were not used to write down the plan, (3) at the stage of carrying out the plan there were some students who have difficulty because they are less thorough so that they are not aware of the mistakes made. This is because students lack concentration in solving problems, (4) at the stage of looking back there are students who have not reached this stage because they have not completed the previous stage.
