Mathematics is one of the subjects that has been taught from the elementary level. However, in reality in the Papua Highlands area thats mathematics is still a problem for both students and teachers. Teachers who are used to teaching using the lecture method make students lazy to take math lessons which results in low math learning outcomes. Mathematics which has an abstract nature requires teachers to be able to concretize it so that it is easily understood by students, considering that students at the basic level are still classified as concrete thinkers. The purpose of implementing this PKM is to provide training for Inpres Tiom Elementary School teachers in creating a pleasant atmosphere for learning mathematics without having to burden students' brains, introduce methods that can be used to teach basic arithmetic, improve student learning outcomes, especially in fostering cooperation between Inpres Tiom Elementary School teacher partners with STKIP Abdi Wacana Wamena. Overcoming the problems above, a solution is provided so that the mathematics lessons being taught become fun lessons for elementary school children, partners are given learning training with the use of visual aids and the application of the jarimatics method. Based on the results of the evaluation of the training activities through the questionnaire provided, it was found that all the teachers who participated in the training strongly agreed with the training activities.

The persistent disparity in students’ mastery of basic arithmetic concepts presents a critical challenge in mathematics education, particularly in regions with limited pedagogical resources. While traditional approaches often fall short in addressing foundational numerical skills, there is a lack of practical, culturally adaptable methods tailored to early secondary learners. This study introduces the "Matahari" method an acronym for Matematika Hitung Jari as a novel instructional strategy that integrates finger-counting techniques with repetitive practice to enhance arithmetic fluency. The primary aim of this research is to examine the effectiveness of the Matahari method in improving the basic arithmetic skills of seventh-grade students at SMP Biji Sesawi Wamena. Employing a quasi-experimental design with a non-equivalent pretest-posttest control group, the study used random sampling to assign students to experimental and control classes. Validated instruments were utilized for data collection, including tests, questionnaires, observations, interviews, and documentation, while data analysis was conducted using One-Way ANOVA and t-tests. The findings revealed a statistically significant improvement in the arithmetic performance of the experimental group, with an average gain of 14.31 compared to 5.46 in the control group. Moreover, the method received highly favorable responses from both students (87.35%) and teachers (78.33%). These results suggest that the Matahari method holds substantial pedagogical value in enhancing numeracy skills and offers a culturally relevant solution for addressing foundational learning gaps in mathematics.
