The Covid-19 pandemic has become a trending topic of conversation for the past year until now, this pandemic has changed various aspects of human life today, especially in the world of education. This causes students' failure to understand mathematical concepts and students' lack of interest in learning. This study aims to describe students' learning interest in the use of E-comic media in social arithmetic material during the Covid-19 pandemic. This research is a descriptive quantitative research. The sample of the research was the seventh grade students of SMP which consisted of 15 students who were taken randomly. The instrument used in this study is a non-test instrument in the form of a student learning interest questionnaire distributed using Google Form in social arithmetic learning using E-comic which consists of 20 statements as a reference to determine students' interest in learning in the use of E-comic media. The data analysis technique used in this research is quantitative descriptive analysis. The results of this study indicate that the use of E-comic learning media is effective on student learning interest during the Covid-19 pandemic with the percentage results80.67% classified as very high criteria. So that the E-comic learning media is very effectively used as a medium for learning mathematics to increase student interest in learning during the Covid-19 pandemic.Keywords: analysis, E-comic, social arithmetic, covid-1 pandemicÂ

The study aims to develop geometric instruments that can be used to improve geometry based on Van Hiele's cognitive level, which is integrated with Malay culture. This study's research design is the Research and Development (R D) proposed by Carson, which consists of several stages, namely: potential and problems, material collection, product design, product validity, product testing, product revision, and mass products. The subjects of this study were 65 students majoring in math education in the first semester. The test instruments were analyzed using Aiken's validity and Cronbach Alpha reliability. The trial analysis was analyzed using descriptive statistics to test students' abilities during three meetings. The data analysis showed that the test instruments were developed in valid and reliable categories. The instruments developed were descriptions in the valid and reliable categories. The instruments in the form of valid and reliable test descriptions can be used to obtain relevant data and improve geometric skills based on the Van Hiele Level, which is integrated with Malay Culture.

This study aims to produce mathematics learning tools in the form Learning Implementation Plans (RPP) and Student Worksheets (LKPD) using a Problem Based Learning (PBL) mathematics learning model on social arithmetic material for class VII tested valid. Development of learning tools in this study uses the method R&D development using the modified ADDIE model into 3 stages, namely: 1) Analysis, 2) Design, 3) Development. In the ADDIE model, the researcher does not use the Implementation stage and the Evaluation stage because at the moment it is still in the atmosphere of the Covid-19 pandemic. The data collections instruments in this study were the RPP validation sheets, and the LKPD validation sheet. The data collection technique used is validation data from 2 Mathematics Education Lecturers FKIP UIR and 2 Mathematics Teachers at MTs Al-Multazam Kerubung Jaya. The analytical techniqueused is validation data analysis. From the results of the study, the result of the RPP validation were 86,83% with a very valid validation level category and 81,54% LKPD validation results with a fairly valid validation level category. Based on the results of these studies, it can be concluded that the development of mathematics learning tools baseb on Problem Based Learning (PBL) in the sevent grade social arithmetic material has been tested for validity.

In order to measure the achievement of students’ competencies, a teacher needs to have the skills to develop various forms of good instruments. One form of the instruments is a test with questions. To have a good instrument, it needs to be analyzed by testing the content validity, construct validity and the reliability of the questions.In compiling the test questions, the plan is also called a grid question that will provide directional guidance. In principle, the grid question that will be carried out is necessary for the expected outcome to be achieved. A careful and conceptual grid question is a guarantee for a teacher in measuring the students’ learning mastery with relevant and representative. If the students' abilities are measurable, information on academic ability and achievement of learning objectives can be obtained. The compiling of the grid question was the solution to the problem above. It was due to the grid question covered the scope and the content of the material to be tested. Therefore, it was necessary to implement an activity of making grid question for teachers of PGRI High School. The method of this activity was a workshop for high school teachers in compiling grid question. The results of this community service show that the motivation and the awareness of teachers about the importance of making good, valid, and reliable grid question were increased.
