Mathematics is often perceived as a difficult subject, therefore students' interest in learning in mathematics is relatively low. This results in low student learning outcomes, whereas in mathematics there is an important ability possessed by students, namely mathematical reasoning abilities that enter into the High Order Thinking Skill, based on that the purpose of this study is to analyze the influence of learning interest on students' mathematical reasoning abilities. The method in this study is a correlational method to see the effect of a variable on other variables, with a population of eighth grade students of SMPN 3 Ngamprah with samples taken in one class. The instrument of this study was a 5-item test instrument to measure reasoning ability and a non-test questionnaire in the form of 40 statements used to measure interest in learning in mathematics. From the results of data analysis, it can be concluded that there is a significant positive influence between learning interest with mathematical reasoning ability, and the correlation coefficient of 0.88, which means the relationship between interest in learning mathematics and mathematical reasoning ability is classified as very strong. Therefore, in bringing learning the teacher should make learning that can increase student interest in learning so that students' mathematical reasoning abilities increase

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
