This research was derived from the low ability of students' problem solving. One of the factors was the students didn't understand the problem of mathematics related to real life and the development of learning media like students' worksheet had not been optimal yet in school. From that case, one of the efforts done was by using students' worksheet based on Contextual Teaching and Learning (CTL). The purpose of this research is to describe the characteristics of mathematical worksheet based on

... TL to improve the problem solving ability of students on the Two Variable Linear Equation System (SPLDV) context in junior high school that fulfills the criteria of valid valid, practical and effective. This research used plomp development model. The plomp model consists of three phases, namely preliminary research, prototyping and assessment phase. Based on the development has been conducted, acquired Mathematics Students' Worksheet based on CTL on the SPLDV context in junior high school valid, practical and effective.
