Development of a Professional 3D Pageflip Based E-Module on Radioactivity Material

Abstract


INTRODUCTION
To be able to produce quality human resources, the learning process must contain two very important elements, namely teaching methods and teaching materials.These two aspects are interrelated.The choice of a particular teaching method will influence the type of appropriate teaching materials.To achieve the excellence that students must have, quality teaching materials are needed.A good teaching material at least includes things like study instructions (student and lecturer instructions), competencies to be achieved, subject matter content, supporting information, exercises, work instructions, evaluations, as well as responses or feedback to the evaluation results (Utami & Syahri, 2007).Apart from that, good teaching materials use good and easy to understand language, are presented in an attractive manner and are equipped with pictures, meet the demands of a curriculum that adapts to the needs of student characteristics, as well as developments in science and technology (Ministry of National Education, 2008).
The achievement criteria for the Physics Education study program are that every Bachelor of Physics Education graduate must have good attitudes and values, mastery of knowledge, work skills and managerial abilities.One of the mandatory courses in the Physics Education study program is Atomic and Nuclear Physics.The expected learning outcomes of the Atomic and Nuclear Physics course are for students to be able to discuss the history of the development of atomic theory, the concept of the hydrogen atomic model, quantum theory, basic concepts of nuclear physics, nuclear structure, radioactivity and nuclear reactions.From the description above, it can be seen that the Atomic and Nuclear Physics course requires students to master knowledge.But in reality, students' conceptual mastery of Atomic and Nuclear Physics material is still low, this is reinforced by the low learning outcomes in Atomic and Nuclear Physics courses.To obtain optimal achievement, an attractive learning environment is needed so that students can be actively involved in learning (Putra, Wirawan, & Pradnyana, 2017).
Based on the results of initial observations on independent physics education students in 2013, information was obtained that: students answered that the main subjects in the core physics course were more difficult than atomic physics with a percentage for core physics of 64% and 36% for atomic physics, the most difficult subject of the study.core physics is nuclear reactions with a percentage of 39%.In the learning process, around 64% of students use Power Point media in addition to reference books.About 95% of students also said that they still need other learning resources to support learning at home.According to the opinion of students who have contracted the Atomic and Nuclear Physics course, the average student answered that they were interested in e-modules compared to printed modules with a percentage for e-modules of 56%.One of the teaching materials used in learning Atomic and Nuclear Physics is printed books.Much of the material presented in printed teaching materials is abstract and complicated, so people are reluctant to read and study it (Kuswandari, 2013).
Based on the results of the observations above, it is necessary to innovate learning by developing teaching materials that are easier for students to understand and have an attractive appearance.One of the teaching materials that can be used is non-printed teaching materials that use electronic media, namely electronic modules or e-modules (Syahrowardi & Permana, 2016).Electronic modules are independent learning media that are arranged in a structured manner to make it easier for students to understand study material at home, on campus or anywhere else well.Apart from the language used being easy to understand, it is also equipped with attractive colors, pictures, animations and videos so that it attracts students' interest.to learn it (Rachmah, Rosha, & Vani, 2017).This electronic module uses the 3D PageFlip Professional application in its creation.3D PageFlip Professional is software that can be used to create teaching materials in the form of digital ebooks with 3D effects.This software is capable of changing PDF teaching materials into stunning 3D flash ebooks in various formats such as Exe, Zip, Html, 3DP, screen saver and others (Amalia, 2015).This research is expected to produce a 3D PageFlip Professional-based electronic module on radioactivity and nuclear reactions in the Atomic and Nuclear Physics course.

RESEARCH METHODS
The research carried out is in the form of research and development or in English it is called Research and Development (R&D).Research and Development (R&D) is a process or steps to develop a new product or improve an existing product, which can be accounted for (Sukmadinata, 2013).The development model used in this development research is a model 4D.This research has 3 stages, namely the definition stage, the design stage and the development stage.
The research instruments used to assess professional 3D pageflip-based electronic modules on radioactivity and nuclear reactions include a student needs questionnaire which contains aspects related to the state of learning nuclear atomic physics as well as things needed in learning Atomic and Nuclear Physics.A questionnaire is a data collection method using a set of written statements for respondents to provide responses according to user requests (Widoyoko, 2016).Next is a validation questionnaire for media experts and material experts containing aspects related to the electronic module material.
Data analysis techniques in quantitative research use descriptive statistics, namely statistics used to analyze data by describing or illustrating the data that has been collected as it is without intending to draw conclusions that apply to the general public (Sugiyono, 2016).Quantitative data analysis was taken from media expert validation questionnaire scores, material expert validation questionnaires, and student perception questionnaires.The data obtained was assessed using a Likert scale.The Likert scale is a scale that measures attitudes towards something which is expressed through a series of statements about a tendency, thing, object, situation and so on and asks the respondent to give an answer whether the respondent strongly agrees, agrees, disagrees or strongly don't agree.(Setyosari, 2015).

RESULTS AND DISCUSSION
The results of the development of the electronic module for Atomic and Nuclear Physics using the 3D PageFlip Professional application on the material Radioactivity and Nuclear Reactions obtained research results that refer to the 4D development model.The 4D stages according to Thiagarajan (1974) are define, design, develop and disseminate.In this research, the stages used were only up to the develop stage.The electronic module design looks like the image below:  Ease of Operation 22.
