This study aims to describe the problem-solving skills of seventh-grade students of junior high school by using a realistic mathematics approach on integers materials. This study was conducted qualitative descriptive research. The subjects of this study were class VII-B students of Junior High School of Nusantara Lubuk Pakam in the Academic Year of 2018/2019. They were 36 students. The instrument of data collection in this study was conducted by problem-solving skills test which included four indicators consisting of comprehending the problem, making plans, implementing the plan, and re-checking the results obtained. The integers test material consists of (1) The recognizing and comparing integers; (2) the addition and subtraction of integers; and (3) the multiplication and division of integers. The results of the study state that the average overall problem-solving skills of students in integer material increases. This can be seen from the percentage of the average score of the overall problem-solving abilities of students from 3 subtopics on integers material. In subtopic 1 were 72.31 %, subtopic 2 were 78.61 %, and subtopic 3 were 81.41 % © Published under licence by IOP Publishing Ltd.
