<![CDATA[This research is based on the background that the importance of social arithmetic lessons for students in mathematics lessons even though during the COVID-19 pandemic, even though social arithmetic is a material that is closely related to everyday life and aspects in it, students are expected to be able to master it. to solve a problem. The purpose of this study was to analyze and describe the difficulties experienced by students when solving social arithmetic problems. This type of research is descriptive qualitative. The first research stage is reducing the data, then presenting the data and finally drawing conclusions. The subjects in this study were students of class VIII SMP Negeri 10 Cimahi as many as 32 students. The instrument used is a test question consisting of 5 description questions arranged based on cognitive level with details from C2 to C5. The results of this study indicate errors that vary, including errors in understanding the concept of material and questions, due to lack of accuracy, and errors in working principles. So it can be concluded that students are still difficult to understand concepts, as well as thoroughness in understanding questions so that they cannot solve problems properly and with appropriate results, students have many difficulties in question number 5, bloom C5 cognitive level on indicators of determining and solving daily problems about a discount of 51.3%.]]>

<![CDATA[The purpose of this study was to improve student learning outcomes in seventh grade junior high school students by using a contextual approach to social arithmetic material. The method used in this research is Classroom Action Research (CAR) which is divided into 3 (three) cycles. The population in this study were students of class VII-B SMP PGRI 5 Cimahi with a total of 31 students consisting of 17 male students and 14 female students. The data collection process is carried out in a planned and systematic manner to monitor the process of learning activities, increase student motivation and improve learning outcomes. Data obtained through questionnaires and cognitive ability tests. The data processing technique in this research is by calculating the percentage of the average of all students and then comparing it with the KKM score at the school. With a contextual approach to social arithmetic material, there has been a significant increase in student learning outcomes from cycle I to cycle III. Completeness of learning in cycle I was 54%, which means that in cycle I there were 17 students who had been able to reach KKM. In the second cycle the completeness increased to 77%, meaning that there were 24 students who had reached the KKM. In cycle III completeness increases to 100%, meaning that in cycle III all students can achieve the KKM score, the achievement of student learning outcomes that meet classical learning completeness based on the average score appears to have met the completeness criteria indicated by the acquisition percentage of 100%. The average score of the first cycle was 67.09, increasing in the second cycle to 74.67, and increasing in the third cycle to 87.58. The highest value in cycle I was 85, increased in cycle II to 90 and increased again in cycle III to 100. The lowest value of cycle I was 50, increased in cycle II to 60, and increased again in cycle III to 75. The meaning of individual completeness was each students have been able to achieve the KKM of 75. Achievement of student learning outcomes that meet classical learning completeness based on the average score appears to have met the completeness criteria indicated by the acquisition percentage of 100%.]]>

<![CDATA[This study aims to describe errors that occur when solving story problems in algebraic form. This study uses a qualitative descriptive method. The subjects in this study used a limited sample of students of SMP Negeri 4 Tambun Utara, as many as 18.92% of students from class VII.5 who had filled out the questions given. The technique used to collect this data is through the answers to the description questions in the form of four questions in the form of story questions and then analyzed by the researchers to see what mistakes students might make when solving the story questions in the algebraic form contained in the student's answers. Through the results of the research and discussion, the researcher concluded that the errors that occurred when solving the questions were as follows: all information and problems in the questions were not rewritten briefly and did not understand the problems in the questions, determined the method of solving that was not appropriate, the existing data was not used during the process. completion, and did not write down the final conclusion that indicated that he had answered the problem in the problem.]]>

<![CDATA[Sosial arithmetic is one of the subject matter of mathematics which includes, among others, buying and selling, profit and loss. Students need to understand this material well in order to be able to apply it in daily life to the fullest. This research is a qualitative descriptive study that aims to analyze students’ mistakes in solving social aritmetic problems, based on Newman’s stages. This research was conducted at SMP Negeri 55 Bandung with the subject as many as 23 students of VIII Grade. The student test results data are in the form of 5 questions, then the errors are analyzed based on the Newman stages and described for each item. The results showed that based on Newman’s stage, the type of error that most students made was process skill error, while the type of error that students made the least amount of error was reading error.]]>

<![CDATA[This research was conducted to analyze the mistakes of student of class VIII at Mahardhika Junior High School in working on social arithmetic materials. This research is based on the importance of social arithmetic materials, which can be useful for students in their lives. The research method used is qualitative descriptive research method. The population of this research was 20 students of class VIII D. Then, the results of this research were obtained from students answers after students were given C1-C6 questions as many as 6 questions. Technical analysis used is to assess the student's answer based on 6 C1-C6 questions that have been given, followed by observing the many mistakes students have in solving the quetion. From the results of the analysis, there are some students who do not understand the formula to do the problem, some students also still do not understand in changing the problem into the math sentence that should be, and some other students still have difficulty in procedural work such as the use of calculating operations in doing problems. So looking at these results, it can be concluded that the ability of students in doing problems, especially social arithmetic materials, is still said to be relatively low.]]>
