<![CDATA[This study examines the mathematical representation of junior high school students in solving AKM problems in terms of mathematical ability. Mathematical representation is a form of presenting one's ideas mathematically in verbal, symbolic, and visual forms. This study aims to describe the mathematical representation among students with different mathematical ability categories. This type of research is qualitative research with a descriptive approach to collect and interpret data. The research subjects involved three junior high school students in grade VIII each having high, medium, low mathematical ability. Data collection methods include math ability tests, mathematical representation tests, and interviews. The data obtained will be analyzed by reducing data, presenting data, and drawing conclusions. The results showed that high ability students fulfilled all aspects of mathematical representation. Students presented the graph appropriately, built the straightline equation correctly, and communicated the answers clearly and logically. Medium ability students also fulfill every aspect of representation, presenting the graph appropriately according to the data given and constructing the straightline equation correctly. However, in communicating the answers, the explanations given were still less systematic and sometimes did not cover all the stages needed in problem solving. Meanwhile, low-ability students only fulfill the visual representation aspect by making a graph according to the data, but have not been able to use it as an analytical tool. Students also had difficulty in constructing straight line equations and drawing correct conclusions.]]>
