Pelatihan Jarimatika Sebagai Strategi Berhitung Cepat: Analisis Respon Siswa SDI Darul Falah

Abstract

Arithmetic skills are essential foundational competencies for elementary school students, supporting their numeracy abilities and understanding of mathematical concepts. However, the results of the observations indicate that the majority of students at SDI Darul Falah have not yet fully mastered the ability to perform basic arithmetic operations quickly and accurately and lack confidence in their mathematics studies. Based on these conditions, the community service activities carried out can help improve students’ performance through the use of the Jarimatika method as an alternative strategy for mental arithmeticThe methods used included a preparatory phase involving coordination with the school and preparation for the community service project, an implementation phase consisting of Jarimatika training, and an evaluation phase based on student feedback during the Jarimatika training sessions. Evaluation was conducted using pre- and post-surveys with a 1–4 Likert scale to measure changes in student responses. The results of the activity showed an increase in positive responses across all indicators, including enjoyment of learning (22%), ability to use fingers (11%), calculation speed (24%), lack of fear of calculating (13%), desire to learn mathematics (11%), student self-confidence (18%), students’ familiarity with finger counting (63%), and students who enjoy and are able to calculate using finger counting (73%). Thus, jarimatika training is effective in improving student responses from both cognitive and affective aspects. These results indicate that jarimatika should be developed as an innovative and enjoyable alternative strategy for mathematics learning in elementary schools
