e-ISSN: 2540-8348 p-ISSN: EFFECT OF USING E-BOOK BALANCING ECOSYSTEM BASED ON CHARACTER EDUCATION (RELIGIOUS VALUES) ON STUDENT LEARNING ACHIEVEMENT

This study aims to determine the effect of using e-book balancing ecosystem based on character education (religious values) on student achievement. This study used experimental research methods and the design used was a quasi-experimental design using post test only control design research. The sample to be used is 40 students of fifth grade Elementary School which are divided into two classes, namely the experimental class and the control class. The data collection techniques used were tests, documentation and observation. After conducting the research, it can be analyzed that the learning achievement scores of the two classes are higher in the experimental class than the control class. After testing the hypothesis (T-test), the results obtained are T count = 3,315> T table 1,686 then H 0 is rejected and H 1 is accepted. Thus, it can be concluded that there is an effect of the application of a character education (religious values) -based ecosystem balance e-book on the learning achievement of fifth grade elementary school students. This can be proven from the posttest value obtained, from the results of statistical tests by obtaining t count (3,315) ≥ t table (1.686). Because 𝑡 𝑐𝑜𝑢𝑛𝑡 ≥ 𝑡 𝑡𝑎𝑏𝑙𝑒 then H 0 is rejected and H 1 is accepted. So that there is an effect of the application of the e-book balancing ecosystem based on character education (religious values) on the learning achievement of elementary school students.


INTRODUCTION
Indonesia is a Pancasila State which means that Indonesia has Pancasila in an effort to maintain the unity and integrity of the nation. The diversity that exists in Indonesia is the hallmark of the Indonesian nation. One of the values contained in Pancasila is the divine value.
This shows that Indonesia is a religious country that always involves divine values in all aspects of life. Divinity is listed in the first sisal Pancasila which reads God Almighty.
Giving religious values is also one of the main things in learning. This is evident in the curriculum currently used in Indonesia, namely the 2013 curriculum (Fahmy, 2015:112) that religious values are the first Core Competencies for students to master. The material and information given to students are expected to always prioritize and integrate religious values. e-ISSN: 2540-8348 p-ISSN: 2088 The giving of religious values is also reflected in the character education given to students. The importance of character education in education is needed for the formation of a dignified character to become a better human being (Sukma, 2017: 184-198).
Recently, we have often encountered in national news that there are often problems related to character problems in children and adolescents (Snyder, 2013: 50-58). The provision of character education from an early age is expected to be able to shape better humans and be able to prepare themselves to socialize in society. Family is the smallest scope that can provide character education for children. After that character education is provided by schools and communities (Shoshani, 2019: 86-102).
Schools have an important role in shaping character education because children have many characters that teachers can develop (Rolina, 2014: 170-174) so that teachers must be creative in order to develop character in children. The provision of character education in schools can be implemented in teaching and learning activities. At the time of the Covid-19 pandemic, many children's learning activities were carried out at home. So that teachers must have creativity in using learning tools that students can use from home and can provide character education to children.
Information and communication technology that is so fast can make it easier for teachers to do learning (Waheed, 2017: 368-379 ) to carry out distance learning for students.
On the other hand, the existence of increasingly advanced education has created new generations that are smart and promising for the future of the nation. One of the factors that influence students' understanding of the material presented is the availability of learning facilities. The learning facilities in question are books as teaching materials and learning media that can help students in learning in class. Student teaching materials also need to be the main focus of the teacher. e-ISSN: 2540-8348 p-ISSN: 2088-3390 E-books are learning media that can be used by teachers in accordance with the development of information and communication technology. E-books are books that can only be opened via electronic media including by using a smartphone so that e-book storage is more flexible and more compact than printed books. With the e-book students will be more happy and motivated in learning (Lai, 2015: 57).
The use of e-books can make it easier for readers to learn something because by using e-books, readers will find what they want to learn (Korat & Or, 2010: 139-154. ). E-books have several advantages that printed books do not have, including e-books that are not as easily damaged as printed books. Previous research has shown that the use of e-books in learning is well accepted by students and parents so that their existence can provide solutions for distance learning that is currently being implemented due to the Covid-19 pandemic.
E-books equipped with character education will be able to realize the ideals of education, namely to educate and shape / develop the character of students to become good human beings and ready to enter the community. In addition, with the e-book, students will better understand and be able to analyze existing material to be able to find the right solution in every life problem. With this character-based education, it is hoped that it can provide more achievements for children to develop knowledge and develop their character. Learning using e-book media can be done anywhere, both at home and at school. Because in this e-book the balance of the ecosystem based on character education (religious values) is accompanied by a worksheet that can activate the role of students in learning because learning is constructive.

In this study, using a Quasi Experimental Design with this type of research is Post test
Only Control Design. The population in this study were students of fifth grade total 76 students who were in four elementary schools. The sample to be used is 40 students of fifth grade Elementary School which are divided into two classes, namely the experimental class and the e-ISSN: 2540-8348 p-ISSN: 2088-3390 control class. The sampling technique used is cluster random sampling. This study used two classes, namely the experimental class and the control class selected randomly or randomly.
The data collection techniques used by researchers in this study were tests, documentation, and observations. In this study, two data analysis techniques were used in this research, namely the feasibility test of questions and data analysis. In the item feasibility test, there are 4 tests including the first, namely the question validity test, in the question validity test the researcher uses IBM SPSS 25 to help with calculations. The second is the reliability test, with the formula: The question is said to be reliable if r count is greater than r  were data on student scores at the end of learning from cognitive, affective and psychomotor learning outcomes, which then the value data researchers would use to test the research hypothesis. The following is data on student cognitive, affective and psychomotor learning outcomes from the experimental class and the control class. The conclusion from the learning outcome data of the experimental class and the control class above regarding the average value of cognitive, affective, and psychomotor learning outcomes can be seen that there are differences in the scores obtained by students between the experimental class and the control class.  Learning using a character education-based ecosystem balance e-book has an influence on the learning achievement of fifth grade elementary school students. By learning using ebooks, the learning achievement value is better than learning not using e-books. So that the use of e-books is now increasingly popular among the public (Jones, 2011: 5-22). In addition, learning to use e-books can increase the speed in understanding a text compared to reading printed books (Huang & Liang, 2015: 864-876 ). One of the factors that can affect the speed of understanding of reading is because students feel happy in learning to use e-books (Lai, 2015: 57).

CONCLUSION
Based on data analysis and discussion of research results, it can be concluded that there is an effect of the application of a character education-based ecosystem balance e-book on the learning achievement of fifth grade elementary school students. This can be proven from the posttest value obtained, from the results of statistical tests by obtaining tcount (
