Teaching materials are an important component in the teaching and learning process. The development of science and technology and the demands of the curriculum in the era of industrial revolution 4.0 are currently forcing teachers to think creatively using science and technology to create teaching and learning processes that can improve student understanding. The current condition forces more learning to be done online, therefore lecturers must be able to develop practical print teaching materials assisted by video tutorials. With this teaching material, it is hoped that it can help students better understand the teaching material independently because This research was conducted to improve the process and learning outcomes of the Actuarial Mathematics course in the Mathematics Department, Faculty of Mathematics and Natural Sciences (FMIPA) Universitas Negeri Medan. The aims of this study are: (1) to develop an ebook for Actuarial Mathematics using the Sigil application, which is tailored to the achievement of student competence in the Actuarial Mathematics course, (2) to describe the steps and results of the validation of the e-book for Actuarial Mathematics so that it is suitable for learning, (3) describing the effectiveness of the Actuarial Mathematics e-book with the Sigil application on student learning outcomes in the Actuarial Mathematics course. This study uses research and development methods with the ADDIE development model consisting of five research stages: need analysis, planning, development, implementation, and evaluation. The results of this study indicate that based on the e-book content validity test, it was found that Actuarial Mathematics teaching materials were in a good category. The contents of the e-book are categorized both in terms of language use, the accuracy of learning materials, and appearance. Then the expert validity test results show that the material developed in the Actuarial Mathematics e-book is in a very consistent category. Furthermore, student responses to e-books used during learning indicate that e-books contribute positively during the learning process. The learning outcomes of students who use e-books are better than those of students who do not use ebooks. © 2022 American Institute of Physics Inc.. All rights reserved.
