TLDR: In this article, the authors describe about mathematics communication in RME setting of junior school student in Semarang City, Java, Indonesia using data obtained from the student's work in solving contextual problems on the subject of the ratio and the system of linear equations with two variables.

Abstract: Purpose of this research is to describe about mathematics communication in RME setting of junior school student. Subject of the research were grade 8 students in Semarang City. Data obtained from the student’s work in solving contextual problems on the subject of the Ratio and the subject of System of Linear Equations with Two Variables. The student’s work is categorized into 5 levels (the lowest level (0) to the highest level (IV)). For leveling researchers developed a scoring rubric with reference to the communication of mathematics quantitative criteria for scoring mathematical communication. Data were analyzed descriptivelyquantitative. The work of students was also analyzed qualitatively by referring to Qualitative Analytic Scoring Procedure for communication of mathematics. The results can be expressed are: for subject ratio: 78% level I, level II, 15%, 5% level III, level IV 2%. As for the subject of Systems of Linear Equations with Two Variables: level I: 67%, level II: 18%, level III: 8%, level IV: 7%. Both of subject in level V were not achieved.
