One of them is by changing teaching materials from textbooks to e-books, which is a must as a form of adjustment related to campus conditions that implement full online learning using LMS SIPDA. The objectives of this study are: (1) Producing an interactive e-book on basics statistics based on Realistic Mathematics assisted by the SIPDA LMS developed by using a valid and practical Kvisoft Flipbook Maker (2) To determine the effectiveness of the e-book Basics of Statistics in improving student problem-solving abilities. This type of research is Research and Development with the ADDIE development model, namely analysis, design, development, implementation, and evaluation. E-book development using the Kvisoft Flipbook Maker Application. The results of the e-book development at the needs analysis stage showed that 85% of students needed integrated learning media. SIPDA integrated e-books can increase student attendance and activities by 60%. At the product design stage, the e-book in the form of a word file is converted into a PDF file and then developed using Kvisoft Flipbook Maker by adding videos, images, and other files. The e-book is validated with a validity rate of 92% by material experts and 89% by media experts. The value of practicality is seen from two things, namely: (1) Questionnaire for responses from media experts and two practitioner lecturers, it was found that the e-book developed could be applied in the good category (3.92) and met the practical criteria (80%) used in the online learning era. (2) The student response questionnaire in a small group of 10 people obtained the category Good (3.96) and very practical (85%). The percentage of student response questionnaire results at the implementation stage of the SIPDA class showed a positive response of 87.6%. The effectiveness aspect is seen from the average individual learning completeness of 71.42 with classical completeness criteria obtained by 91. And the N-Gain score was 0.71 in high category.]]>
