Abstract
Cultural context is rarely used in learning mathematics. In cultural education, it has become one of the goals of mathematics education that education is both a form and a product of culture. The purpose of this study is to understand the design of an instrument to test students^ mathematical literacy skills in geometry plane figures based on Malay culture and to analyze students^ mathematical literacy skills of students based on Malay culture. This study follows descriptive qualitative research. The sample of this study includes students of XII MA Private Hj. Siti Julia Secanggang, Langkat. Test validity, test reliability, level of difficulty, and discriminating power were declared feasible by using the SPSS program. Expert validation was carried out by lecturers in the mathematics education study program and teachers in the field of mathematics studies. It was found that the instrument for testing students^ mathematical literacy skills was valid in terms of content, language, and constructs. The results of the Malay culture-based students^ mathematical literacy test results obtained an average score of 84.25 with the lowest score of 70 and the highest score of 95.
