This study aims to analyze and categorize in accordance with the validity, reliability and difficulty index of each item of barisan and series material in high school students class XII IPA 4 in one of the public schools in Cimahi city with a sample used by 28 people. The indicators used to analyze the problem are based on a revised Bloom Taxonomy that contains the cognitive domain levels C2 (understanding), C3 (Applying), C4 (Analyzing), C5 (Evaluating) and C6 (Creating). This type of research is qualitative descriptive research. The analysis is done by giving a written test in the form of a description question that amounts to 10 questions, then analyzing the test results that have been done. The method used is content analysis with the help of Microsoft Office Excel. The results of the analysis showed that out of the 10 question items tested there are 6 questions that can be used with the average result of validity and reliability in the moderate category as well as a difficulty index that shows the categories of easy, medium and difficult questions.

The current situation is hit by the COVID-19 pandemic, so research is carried out through online learning on social arithmetic material with the aim of describing and knowing students' difficulties when working on questions. The data collection technique used Google forms and the research subjects were in class VIII H at SMPN 1 Nagreg, totaling 20 students. The method in this research is descriptive qualitative, the research instrument is a test of social arithmetic material in the form of 5 description questions. Factors that cause difficulties in working on social arithmetic problems, including: (1) in understanding the questions students have difficulty (2) students find it difficult to transform questions; and (3) students find it difficult to work on the questions. The results of this study obtained data that it is still difficult for students to solve social arithmetic problems. The percentage value of students' answers is mostly on the indicators determining gross, net and tare in the cognitive domain of C5 with a percentage of answers of 35% including the very low category.

This type of research is a qualitative descriptive study that aims to analyze the mistakes of junior high school students in completing social arithmetic material. The subjects used were 20 students of class VIII-C SMP Sejahtera 2 Cileungsi, one of the private junior high schools in Bogor Regency. The data collection technique used was in the form of student test results with written questions in the form of descriptions of 5 questions, then each error faced by students was described in each question number on the social arithmetic material. The data analysis performed was data reduction, data presentation and conclusion drawing. The highest percentage of errors was in question number 4, which was 75%, while the lowest percentage of errors was in question number 2, which was 10%. Based on the results of the study, it showed that there were several mistakes in solving the essay questions, namely errors in understanding the basic concepts, errors in principle in reading the essay questions, and errors in operating the data contained in the questions. The conclusion from the results of this study obtained data that the ability of students still experienced many errors in solving social arithmetic questions.

ABSTRAKPengabdian ini, berdasarkan hasil observasi kami dilapangan, hasil belajar matematika siswa di Sekolah Dasar Masih rendah, padahal pada jenjang ini sangat menentukan keberhasilan belajar pada jenjang selanjutnya. Rendahnya hasil belajar siswa SD pada mata pelajaran matematika dikarenakan siswa menganggap matematika adalah pelajaran yang sulit, mereka merasakan kesulitan dalam matematika karena pada jenjang Sekolah Dasar siswa masih belum bisa berpikir abstrak, padahal matematika adalah ilmu yang abstrak. Oleh karena itu pada jenjang sekolah dasar dibutuhkan media berupa alatperga yang dapat membantu siswa membayangkan atau mengilustrasikan konsep-konsep matematika agar konsep matematika lebih mudah dipahami. Keterbatasan alat peraga menjadi salah satu hambatan dalam pembelajaran matematika di Sekolah Dasar, selain itu keterbatasan pengetahuan guru mengenai alat peraga menjadi salah satu hal yang harus diperhatikan. Berdasarkan pemaparan tersebut, kami bermaksud untuk melakukan penyuluhan kepada guru-guru di beberapa SD di Kecamatan Pangalengan dalam penggunaan alat peraga khususnya pada matapelajaran matematika, diharapkan dengan adanya penyuluhan tersebut pengetahuan guru mengenai alat peraga semakin meningkat yang berimplikasi pada meningkatnya hasil belajar siswa pada matapelajaran matematikaKata Kunci : Alat Peraga, Matematika, Sekolah Dasar ABSTRACTThis dedication, based on our observations in the field, mathematics learning outcomes of students in elementary schools are still low, even though at this level it will determine the success of learning at the next level. The low learning outcomes of elementary school students in mathematics because students consider mathematics a difficult subject, they feel difficulties in mathematics because at the elementary school level students are still unable to think abstractly, even though mathematics is an abstract science. Therefore at the elementary school level media needed in the form of tools that can help students imagine or illustrate mathematical concepts so that mathematical concepts are more easily understood. The limitation of teaching aids is one of the obstacles in learning mathematics in elementary schools, besides the limited knowledge of teachers about teaching aids is one thing that must be considered. Based on this explanation, we intend to conduct counseling for teachers in several elementary schools in Pangalengan District in the use of teaching aids especially in mathematics, it is expected that with this education the teacher's knowledge about teaching aids will increase which has implications for increasing student learning outcomes in mathematics.Keywords: Teaching Aids, Mathematics, Elementary School

Students who are at the viiith level of junior high school must learn the Two-Variable Linear Equation System (SPLDV). The reason for the study was to see the mistakes of students when working on material problems of the Two-Variable Linear Equation System (SPLDV) using a problem-solving approach. Participants in this study were 32 students of class VIII of SMPN 1 Cililin consisting of 14 men and 18 women. The procedure for the information collection process uses a written exam which is an overview of 5 questions that show problem-solving skills. The data investigation is completed by examining the results of the experiment, then proceeding with drawing conclusions. from this review it can be seen that there are some learners who have misrepresented the question of portrayal of SPLDV material. Based on the studies conducted, there are aspects that trigger students' mistakes in responding to questions, including: 1) Students do not answer questions according to the established strategy. 2) Students are less careful in doing mathematical calculations to complete the theoretical formulations that have been designed and 3) Students do not see the answer again, as a result of which they do not follow a methodical process.

Learning difficulties are external factors that have an impact on the low learning outcomes of students in mathematics. Another element that adds to learning difficulties is the lack of enthusiasm (motivation) for learning and makes students reluctant and lazy to learn mathematics. The reasons for carrying out the analysis of this study include finding, identifying and assessing learning difficulties faced by class VII students at SMP Negeri 1 Cililin, as well as students' mistakes when working on set material questions. The method used in this research is by using descriptive qualitative method. Participants in this study were 18 students. The approach of collecting data in this research is by giving a test test of three questions in the form of a description. Based on the money study that has been carried out, there are several aspects of learning difficulties including although most students already understand the concept of the set, they still experience some learning difficulties, such as not being able to understand the problem, not being careful in recording the members of the set, and having difficulty in making the required mathematical model.
