<![CDATA[This study aims to describe the mistakes made by students of grade IX Middle School. As well as analyzing the factors that cause students to mistake in completing the material on flat side spaces in junior high school students in Cimahi City. The method used in this research is descriptive qualitative. The sample taken for this study was 10 students of class IX in one junior high school in Cimahi City. The test instrument was given as many as 5 items. Based on the results of data analysis, it can be concluded that there are errors in solving the problem of getting up the flat side space, namely: (1) not understanding the basic concept of building a flat side space; (2) lack of understanding of questions or lack of thoroughness in reading problems so students' answers are incomplete; (3) lack of mastery of the principle or conceptual relationship between flat figures (prerequisites regarding the Pythagorean theorem); (4) don't memorize the formula; (5) lack of precision in the calculation process. And this shows that grade IX students in Cimahi City are still low in solving problems in the material to build flat side spaces.]]>

<![CDATA[This study aims to analyze the problem solving ability of high school students on trigonometry material. The method of this study is a qualitative descriptive method with the research subject of 30 students of class XI in one of the Kab. West Bandung. The data collection instrument used was in the form of a description test consisting of 4 questions with indicators of problem solving abilities. The results of student answers were analyzed using a scoring rubric which was compiled based on 4 indicators of problem solving ability, namely: 1) understanding the problem, 2) planning problem solutions, 3) implementing a settlement plan, 4) looking back. Then the data is processed by calculating the percentage of student achievement against each problem solving indicator. Based on the results of the study, it was found that students had not mastered the indicators of implementing the completion plan and looking back at the percentages 52.5% and 37.5% respectively. Students with high abilities and are making mistakes because students are less careful when solving problems with different error levels. Meanwhile, students with low abilities make mistakes due to a lack of student understanding of problems and concepts.]]>

<![CDATA[This study aims to analyze the location of the errors experienced by MTs students in solving the Two Variable Linear Equation System (SPLDV) questions in online learning. This study uses a qualitative descriptive method. The subjects are students of class IX in Karawang totaling 16 people. Data collection is done by analyzing 5 items of description. The problem indicators used are (1) Creating SPLDV as a mathematical model of the given situation, (2) Creating a mathematical model and determining the completion of SPLDV using the graphical method, (3) Creating a mathematical model and determining the completion of the SPLDV using the elimination method, (4) Making mathematical model and determine the solution of SPLDV by substitution method, (5) Identifying special SPLDV and its solution. Based on the results of the study, the highest student errors were found in the indicators of making mathematical models and determining the completion of the SPLDV using the graphical method with an error percentage of 87.5% (where the minimum criteria were 75%). Based on the results of the analysis, the factors that make these indicators experience errors are that students have difficulty in transforming story questions into the form of mathematical models and difficulties when drawing graphs, this happens because during online learning the concept construction process and the form of visualization when constructing concepts are very difficult to facilitate.]]>

<![CDATA[This study aims to analyze student errors in solving math problems in algebraic material. The algebra questions tested have been compiled based on Bloom's taxonomy. The indicators in each question contain various abilities that exist in Bloom's taxonomy, such as the ability to calculate, relate, conceptualize, investigate and others. The method used in this research is descriptive qualitative research. The subjects of this study were students of class VII-B SMP Marga Utama Padalarang. Many samples in this study were 20 students consisting of 10 male students and 10 female students. The items tested are 5 items with the type of essay questions. Based on the results of data analysis in the form of a test consisting of 5 algebraic essay questions, it shows that there are differences in the errors made by male students and female students. The most errors in solving algebra questions were made by male students, as many as 70%. The error is because students are accustomed to practice questions given by teachers not using Bloom's taxonomy when designing the questions. In other words, students are only used to the same questions as the example questions explained by the teacher before. As a result, students find it difficult when solving algebra problems that have been designed using Bloom's taxonomy and end up making many mistakes when answering the questions.]]>
