Abstract :
This research aims to produce student Worksheets (LKPD) the integration of Islamic are material equations and linear inequalities of one valid and practical variable. The method that researcherdo is development used modified Research and Development (R & D) so, there are several stages, namely: (1) Potential and Problems; (2) Data Collection; (3) Product Design; (4) Design Validation; (5) Design Revision; (6) Product Testing; (7) Product Revision; (8) Final Products. This product trial was carried out in class VII of Abdurrab IT Middle School with 26 students. The data collection instrument in this study was the LKPD validation sheet with three validators, namely two mathematics lecturers at FKIP UIR, and one educator fromschool, the educator's response sheet, and the student's response sheet. The data analysis technique used are descriptive analysis that describes the validity and practicality of the LKPD developed by researcher. The results of the three validators obtained a percentage of 83.78% with valid criteria. Then,the results of practicality the first meeting obtained 83.09% with very practical criteria, Meeting II obtained 86.81% with very practical criteria, Meeting III obtained 79% with practical criteria, meeting IV obtained 83.21% with criteria very practical. Based on the results of the study it can be concluded the research on the Development of Student Worksheets (LKPD) Based on Islamic Integrated Problem Based Learning in the material of Equations and Linear Inequalities in One Variable of Class VII Middle School is validity and practicality.
