    Abstract

    Kemampuan komunikasi matematis merupakan salah satu kompetensi penting yang perlu dimiliki siswa dalam pembelajaran matematika, karena berperan dalam mengekspresikan ide, memahami konsep, serta menyampaikan pemikiran secara logis dan sistematis. Namun, berbagai penelitian menunjukkan bahwa kemampuan ini masih tergolong rendah pada sebagian besar siswa. Salah satu faktor internal yang diduga berpengaruh terhadap kemampuan komunikasi matematis adalah self-efficacy, yaitu keyakinan individu terhadap kemampuannya dalam menyelesaikan tugas tertentu. Penelitian ini bertujuan untuk menganalisis pengaruh self-efficacy terhadap kemampuan komunikasi matematis siswa SMA pada materi statistika. Penelitian menggunakan pendekatan kuantitatif dengan metode korelasional. Instrumen penelitian terdiri dari angket self-efficacy dan tes uraian untuk mengukur kemampuan komunikasi matematis. Data dianalisis menggunakan regresi linear sederhana. Hasil penelitian menunjukkan bahwa terdapat hubungan positif antara self-efficacy dan kemampuan komunikasi matematis siswa, dengan kontribusi sebesar 9,4%. Artinya, semakin tinggi tingkat self-efficacy yang dimiliki siswa, maka cenderung semakin baik pula kemampuan komunikasi matematisnya. Selain itu, ditemukn juga bahwa terdapat hubungan positif antara self-efficacy tinggi dan kemampuan komunikasi matematis siswa dengan kontribusi sebesar 18%. Namun, ditemukan bahwa self-efficacy rendah dan sedang tidak memberikan pengaruh yang signifikan secara statistik. Peneliti selanjutnya dapat mengembangkan hal yang belum dilakukan dalam penelitian ini. Mathematical communication ability is one of the essential competencies students need in mathematics learning, as it plays a role in expressing ideas, understanding concepts, and conveying thoughts logically and systematically. However, various studies show that this ability is still relatively low among many students. One internal factor suspected to influence mathematical communication ability is self-efficacy, which refers to an individual's belief in their ability to complete specific tasks. This study aims to analyze the effect of self-efficacy on senior high school students’ mathematical communication ability in the topic of statistics. A quantitative approach with a correlational method was used. The research instruments consisted of a self-efficacy questionnaire and an essay test to assess students’ mathematical communication skills. Data were analyzed using simple linear regression. The results revealed a positive relationship between self-efficacy and students’ mathematical communication ability, with a contribution of 9.4%. In other words, the higher the students’ self-efficacy, the better their ability to communicate mathematically. Additionally, the study revealed a positive relationship between high self-efficacy and students' mathematical communication ability, contributing 18% to the explained variance. However, it was found that low and moderate self-efficacy levels did not significantly affect communication ability. Future researchers may explore aspects that have not been addressed in this study.
