This study aims to analyze: (1) the validity of maple-based integral calculus textbooks; (2) the effectiveness of textbooks that have been designed to increase understanding of students' mathematical concepts; (3) the practicality of textbooks that have been designed to increase understanding of students' mathematical concepts. The method used in this study was research and development (R & D) with the design of the development of the Plomp model which consists of five stages in the form of (1) initial investigation, (2) design, (3) realization / construction, (4) test, evaluation and revision, (5) implementation. The research subjects were the STKIP Soe mathematics education students in the even semester 2017/2018 academic year who took integral calculus courses consisting of 2 (two) classes namely the experimental class consisting of 14 people and a control class consisting of 15 people. Instruments and data collection techniques used in the form of observations, tests and questionnaires. Data analysis using independent sample t test and normalization gain score. The result of this study showed that the calculus integral materials (book) maple based was valid, effective and practical in increasing students’ math understanding concept.
