DEVELOPMENT OF INTERACTIVE TEACHING MATERIALS (3D PAGE FLIP) ON SCIENCE LEARNING FOR JUNIOR HIGH SCHOOL STUDENTS IN KECAMATAN PINGGIR-MANDAU

This study aims to: a) to find out the validity of interactive teaching materials (3D Page Flip) by experts, b) to find out the validity of interactive teaching materials (3D Page Flip) by the audience. In this study also using a limited method (RnD), namely Limited Research and Development, namely by using two media experts and 10 junior high school students in The District Edge-Mandau grade VIII. The process of media development starts from media planning, media creation according to design, experiments and also revisions of the results of the experiment, in the process of developing interactive learning media (3D Page Flip) requires an application assistance in its implementation of 3D page flip application. In this study the instrument was given to two expert lecturers with a result of 81.6% with valid validation, feasible, appropriate and without revision. Instruments were also given to an audience of 10 junior high school students in grade VIII at SMP Subdistrict PinggirMandau with a validation score of 95% with very valid results, very suitable and without refisi. The conclusion of this research is interactive teaching material (3D Page Flip) in science subjects in junior high school grade VIII semester 1 can be used as teaching materials in junior high school.


Introduction
Teaching and learning activities consist of three important components, namely students, teachers and teaching materials. In the attachment permendiknas No. 16 year 2007, that teachers as professional educators are expected to be able to develop teaching materials. To achieve an optimal teaching and learning process, teaching materials are one of the important things Teaching materials that have been the teacher's hand obtained from the publisher. So that the teaching material is less interesting because of the lack of animated images and animations that make students more happy to learn it (Hidayatullah, et al. 2013).
Nowadays, there are interesting teaching materials where many animated animations can visualize abstract concept concepts, so that students can get an idea of abstract concept concepts in the teaching and learning process (Harjadi and Sulisworo, 2014).
Teaching materials can provide good benefits for teachers and students, namely (a) making teaching and learning activities more interesting, (b) fostering students' desire to learn independently with teacher guidance, (c) students easier to understand each competency (d) teaching materials developed by the teacher more in accordance with the needs of the students. (Ministry of National Education, 2008).
Nowadays, the teaching and learning process must be able to follow the development of science and technology to train learners to master not only knowledge but also, concepts, scientific principles and also skills, one of which is teaching materials (3D Page Flip).
Teaching material (3D Page Flip) is a sheet of sheet paper containing material with images and also videos that can increase the interest of students to learn the teaching material (Nurseto, 2011).
Teaching materials (3D Page Flip) have several advantages such as: it can present material in the form of words, images and videos equipped with attractive colours (Suslilana and Riyana, 2008).
But teaching materials (3D Page Flip) has disadvantages namely: need a sophisticated gadget or have to use a Pc to access it (Wahyuni et al, 2014). This teaching material (3D Page Flip) is a very suitable teaching material applied to science subjects because in the process of teaching and learning images and video are needed in real life to improve students' understanding (Hayati, 2015).

Research Method
This type of research is (RnD) limited i.e. Limited Method Research and Development. The resulting product is learning media (3D Page Flip) in science subjects in junior high school in Pinggir-Mandau Village.
The This trial phase is carried out to find out the feasibility of teaching materials to be developed. This stage is carried out to validate the product by the material expert, as well as the student. e. Product revision At this stage, revision of teaching materials based on input on the trial.
Data collection instrument was with expert research sheet and student response questionnaire sheet used to find out student's response on the efficiency of teaching materials (3D Page Flip) science. The technique used in analyzing data by experts to validate learning media (3D Page Flip) is to use validation sheets.
Expert validation was conducted by two lecturers from the Science Education Study Program, Medan State University, namely Mr. Aristo, S.Pd., M.Pd. and Mr. Halim Simatupang, S.Pd., M. Pd. And audience validation involving 10 students from junior high school in Pinggir-Mandau subdistrict from the results of student post tests

Result
This research produced learning media products (3D Page Flip) in science subjects in junior high school. Learning media (3D Page Flip) is a book containing materials, images, animations, and also videos in the form of soft copy.
In learning media (3D Page Flip) was developed as a whole starting from: a) cover; b) table of contents; c) list of images; d) table list; e) observing activities; f) sample questions; g)practice questions; h) video.  Audience validation data is data used to determine the effectiveness of teaching materials (3D Page Flip) science and its implementation in junior high school students, from pretest results and also post tests and student response questionnaires. Pretest and post test questions are the same as the number of 10 multiple choice questions against the developed learning.
Based on table 2, it can be seen that the percentage percentage of student responses is very valid, very effective and can be used without revision

Conclusion
Based on data obtained from the development of learning media (3D Page Flip) in science lessons in junior high school in Pinggir-Mandau subdistrict it can be concluded that: 1) the development of interactive defense media (3D Page Flip) in science subjects get validation test results of 81.6% of this media shows this learning media is valid. 2) Interactive learning media (3D Page Flip) IPA based on respondent audience get results of 95% this indicates that the development of interactive teaching materials IPA very valid and can be used without revision.
