<p><em>This research aims to establish a valid, practical, and effective media in the form of a game called Baret Argeo for students interest in learning at Senior High School 6 of Purworejo during online learning. This research is a development study that employs the ADDIE method (analysis, design, development, implementation, evaluation).A required analysis is carried out according to pandemic conditions during the analysis stage. The Baret Argeo design and components were produced during the design stage. Validation was carried out by content experts with a value of 3.93 (valid) and media experts with a value of 4.46 at the production level (very valid).which was then put to the test on 18 students in a practicality test with a score of 4.03 (very practical).</em> <em>Then the implementation of the 18 students used the Argeo Beret which was compared with the other 18 students who used the Student Worksheet (LKS) using the t test comparative analysis. The result is </em> <em> with 4.4881> 2.0322 then </em><em> is rejected or it can be said that students' interest in learning using Beret Argeo is better than students using LKS. At the evaluation stage, the Argeo Beret is reserved to be used in a wider range of mathematics learning. This research has implications for students' interest in learning in the middle of distance learning.</em></p>Muhammad Ikhsan FaizTeguh WibowoBambang Priyo Darminto

<p><em>Poverty is one of the main problems of the government that is prioritized in developing the development strategy of every country including Indonesia. The poverty rate in Indonesia is still relatively high, so the government focuses on decreasing the existing poverty level by improving the welfare of the population. Therefore, it is very important for the government to know the severity of poverty in Indonesia so that it can take a policy to reduce the existing poverty level. The purpose of the research was to group the severity of provincial poverty in Indonesia with a Discriminant Analysis. The stages of discriminant analysis include testing of normal multivariate distribution, testing of homogeneity of covariance variants, discriminant analysis by stepwise method, then continued calculation of classification accuracy value. The results of this research show that the large classification rate obtained is only 67.7% which means that not all provinces are able to be classified appropriately based on the variable open unemployment rate (TPT).</em></p>Ni Putu Nanik HendayantiMaulida Nurhidayati

https://ejournal.uinib.ac.id/jurnal/index.php/matheduca/article/view/2504
<em>One of the reasons for the low student achievement in mathematics is that the mathematics learning process carried out by the teacher tends to be theoretical and less contextual. Mathematics learning needs to be linked to student culture so that there is no gap between mathematics in everyday life and at school. Thus, it is necessary to apply a mathematics learning model based on ethno-mathematics. This study aims to determine the effect of the ethnomatematic based probing-prompting learning model on students' mathematics learning achievement. This type of research is quantitative research with pre-experimental methods and one-group pretest-posttest design. The sample of this research is class VIII A SMPK St. Yoseph Naikoten Kupang, totaling 24 people. The pretest and posttest values as research data were analyzed using the SPSS version 22 program. Based on the results of data analysis, </em>t<sub>hitung</sub> (39,594)> t<sub>tabel</sub> (2,069) <em> with an error rate of 0.05, which means accept Ha or the ethnomatematic based probing-prompting learning model has an influence which is significant towards the mathematics learning achievement of students class VIII SMPK St. Yoseph Naikoten Kupang.</em>Osniman Paulina MaureKondradus Silvester Jenahut

<p><em>Transportation problems</em><em> such as transportation activities and allocation to reach consumers is one of the factors that determine the level of satisfaction. To find the level of customer satisfaction, it requires an appropriate and efficient transportation model. O</em><em>ne of which is in the Air Minum Mata Air Sikumbang business owned by Mr. Zulfikar, located in Rumbio, Kampar. Based on the results of the study the cost of distributing drinking water is still not </em><em>efficient</em><em> because it still uses</em><em> </em><em>estimation and there is n</em><em>o separate technique</em><em> used to allocate water distribution. The solution made in this study using the Karagul-Sahin Approximation Method for the initial basic feasible solution and Stepping Stone for the optimal solution value so as to obtain the distribution of water at a minimum cost. Based on research using the method of Karagul-Sahin Approximation and Stepping Stone, a weekly cost savings of Rp.469.515,00 is obtained.</em><em></em></p>Sri BasriatiElfira SafitriDinda Kurniyawan Nusantoro

<p><em>Mathematical communication skills are one of the competencies that students must have in the 21<sup>st</sup> century. This study aims to anylize and describe students’ mathematical communication skills in terms of self efficacy on the polyhedrons material. The research used descriptive qualitative methods. The subjects were 9 grade students of An nashichah private junior high school selected purposively. Data was collected through online test, questionnaires and interviews using WhatsApp. The data analyzed through 3 stages, namely data reduction, data presentation and conclusions. The results showed that the students’ mathematical communication skills were low. When viewed from students’ self efficacy, high self efficacy students have high mathematical communication. Meanwhile, low and moderate self efficacy students have low mathematical communication skills. The use of Whatsapp media is not able to support students mathematical communication skill and self efficacy. The tachers need to design learning media to help students improve their mathematical communication skills and self efiicacy.</em></p>Nur Asri MelawatiErdawati Nurdin

<p><em>The ability to think creatively is needed by students in mathematics learning activities, because creativity raises ideas in solving mathematical problems, so that the expected learning objectives are achieved. In addition, the mathematical resilience factor is needed to make students more persistent, never give up, enjoy being challenged, so that students' perspective on mathematics is not something to be afraid of anymore. This study aims to determine the effect of an open-ended approach on the mathematical creative thinking ability based on the mathematical resilience of Madrasah Tsanawiyah (MTs). This type of research is an experimental design that uses a factorial design. The selected population has been subjected to a one-way ANOVA test with the results having an average similarity, so that the sample was taken using the Cluster Random technique with randomly selected samples, namely class VIII-1 which was selected as the experimental class and class VIII-2 was selected as the control class. The results showed: 1) there were differences in mathematical creative thinking skills between students learning with open-ended learning and students learning using conventional learning; 2) there are differences in mathematical creative thinking abilities between students who have high, medium and low mathematical resilience; 3) while for interaction there is no interaction between the open-ended learning approach and students' mathematical resilience to mathematical creative thinking abilities. So the results of this study can be used to improve mathematics learning in class.</em></p>Ramadani RamadaniRamon Muhandaz

<em>Tadris Mathematics is one of the study programs at UIN IB Padang with the vision "To produce character, professional and competitive mathematics education graduates in 2037". In order for this vision to be realized, of course there must be interesting interactions between lecturers and students in lectures. Meanwhile, the reality that occurs in lectures, there are still many students who are passive and result in many student scores that have not passed after taking the exam. One of the ways that a lecturer can do to overcome this problem is by developing Mathematical Statistics teaching materials based on problem solving and Islamic nuances. The formulation of the problem in this research is how the process and results of the development of Mathematics Statistics Subject Teaching Materials Based on Problem Solving and Practical Islamic Nuances in small group evaluations. This research is a development research with the Plomp development model using Tesmer's formative evaluation. Data collection techniques using practicality questionnaires from the teaching materials developed.
