INTRODUCTION
The Directorate General of Higher Education (2009) said that textbooks are handbooks for subjects written and compiled by experts in related fields and fulfilling the rules of textbooks. In the field of education, textbooks are closely related to the learning process and curriculum. Textbooks are a means for implementing education and learning. During learning, the teacher can manage learning activities with the help of books. Students or students can participate in learning activities through book means.
Sports Nutrition Science is one of the compulsory subjects in the Physical Education Study Program and Recreation IKIP Budi Utomo Malang. Sports Nutrition Science is the study of the relationship between food management and physical performance that is beneficial for health, fitness, child growth and sports achievement development, especially for sportsmen. The subject of Sports Nutrition Sciences aims to understand the relationship between nutrition, lifestyle and physical performance. Athletes must have appropriate nutrition to obtain optimal health and physical abilities so as to enable them to endure hard physical training and be able to maintain a good appearance during the game.
Interviews with students of the Health and Recreation Physical Education Study Program showed that 80% of students were less interested in sports nutrition courses. They consider the subject of Sports Nutrition to have nothing to do with the world of sports. This fact makes the lecture in Sports Nutrition less meaningful. Most PJKR students consider Sports Nutrition as a difficult subject. It is not surprising that the results of the Sports Nutrition Science study of the PJKR Study Program students, especially at the IKIP Budi Utomo Malang, are still relatively low. Each semester final examination Minimum Completion Criteria (KKM) is only 45% to 55%.

METHODS
The development of this Sports Nutrition Science teaching book refers to the 4D model developed by Thiagarajan, et al. (1974) which consisted of 4 stages, namely Define, Design, Development, and Disseminate, which were modified to be adapted to this study.

Define Stage
At this define stage, conduct an instructional needs analysis needed for the development of textbooks which includes steps: (1) Analyzing basic competencies in Sports Nutrition Science courses, (2) Identifying learning problems, and (3)

ABSTRACT
This study aims to determine the results of the feasibility of the material aspects and media of sports nutrition teaching textbooks. This research is a research on the development of sports nutrition science textbooks. The development of the teaching book on Nutrition Sports Science refers to the 4D model developed by Thiagarajan, et al. (1974) which consists of 4 stages, namely Define, Design, Development, and Disseminate, modified to be adapted to this study. This textbook is tested by material and media experts. The instrument used is an expert validation instrument. Based on the results of the study it can be concluded that the Sports Nutrition Science textbook was declared fit for use as a sports Nutrition Science textbook by material and media experts.

Design Stage
The design phase was carried out to produce an initial draft of the Sports Nutrition Science textbook.

Stage of Develop
This development phase aims to revise the initial draft textbook that has been prepared at the design stage. The revision is based on the validation process carried out by material and media experts. After the validation and revision is complete, a development test is carried out which includes individual testing, small groups and Classroom Action Research (CAR).

Disseminate stage
In this desiminate stage, dissemination of textbooks to be used in lectures on Sports Nutrition, especially for Health Physical Education Study Program and Recreation IKIP Budi Utomo Malang.

Feasibility Sheet Data Analysis
Descriptive statistical analysis was used to process data obtained from student validation sheets and assessment questionnaires. Data will be converted in percentage form with the following formula: xi Information: P = Percentage of each criterion x = Score for each criterion xi = Maximum score for each criterion

RESULTS AND DISCUSSIONS
This textbook is validated by material and media experts. The results of the assessment of each validator are calculated and made in the form of percentages. The assessment results indicate that the assessment of the feasibility of Sports Nutrition Science teaching books by material experts is "very feasible" and the feasibility assessment of Sports Nutrition Science teaching books by media experts is "feasible". In addition to assessments in the form of numbers, material experts and the media provide several suggestions as a reference for the revision of textbooks. Suggestions/comments from Media Expert as in the following table 3.

CONCLUSION
Based on the results of the study it can be concluded that the Sports Nutrition Science textbook was declared fit for use as a sports Nutrition Science textbook by material and media experts.
