Multimedia Design for Geometric Optical Material Using Professional Adobe Flash CS5 Software

Abstract


INTRODUCTION
In the teaching and learning process in higher education, the presence of learning media is seen as one of the factors that can increase the effectiveness of the learning process.An educator must be able to master the methods and selection of appropriate media in teaching (Emda, 2011).The development of educational technology cannot be separated from the development of technology in general (Haryoko, 2009).This is because media has a function that can directly and indirectly influence students' motivation and interest in learning and the meaning of learning materials will be clearer (Arsyad, 2013).If you only use textbooks and whiteboards, this goal will be difficult to achieve.The word "Media" comes from Latin which is the plural form of "medium", literally meaning intermediary or introduction (Tejo, 2011).Media is anything that can convey and channel messages from sources in a planned manner so as to create a conducive learning environment where recipients can carry out the learning process efficiently and effectively (Mudani, 2013).This also allows learning goals to be achieved which ultimately can improve the learning process and outcomes.
Basic Physics course material requires supporting media as a complement to student textbooks because many concepts are only outlined in text, pictures and formulas, especially Basic Physics II.
However, based on the author's knowledge, not much media has been created for Basic Physics II, especially for Geometric Optics material.Geometric Optics itself is a branch of science that studies light, the properties of light propagation, such as reflection, refraction, and the principles of the path of rays.To describe how light and the properties of light propagate, media is needed that can describe and show it clearly and can be accepted by students.
One of the learning media that is popular with students is computer media.However, among the many computer software, Adobe Flash was chosen because it has many complete supporting features.Adobe Flash CS5 has several advantages with its newest features where the software has added and changed commands to make it easier for users to manage animations (Budi, 2013).The new version of Adobe Flash Professional is Adobe Flash Professional CS5.This version is much better than the previous version because Adobe Flash Professional CS5 has several advantages with its newest features where the software has added and changed commands to make it easier for users to manage animations.Therefore, the author tries to express the concept of Geometry Optics in a learning media using light material which usually appears as a group of light rays or also called light beams (Young, 2003), with the Adobe Flash Professional CS5 application so that the theory can be used.visible and accepted by students.
To express the concept of Geometric Optics in a learning medium using the Adobe Flash Professional CS5 application means that the author will carry out research in the form of R & D (Research and Development), where this research is carried out to develop a new or existing product and test its effectiveness.these products (Sugiyono, 2014).

RESEARCH METHODS
The research carried out is in the form of research and development or in English it is called Research and Development.Development research is research used to produce certain products and test the effectiveness of these products (Sugiyono, 2014).The development model used in this development research is a procedural model.Setyosari (2010) explains that, "A procedural model is a descriptive model that describes the flow or procedural steps that must be followed to produce a particular product."In this model research, there are three stages that must be passed, namely the initial stage (preparation), the creation stage (development), and the evaluation stage.Next, the questionnaire was analyzed using validity, reliability and scale analysis.Validation is a measure that shows the levels of validity or validity of an instrument (Arikunto, 2010).

RESULTS AND DISCUSSION
The following is an analysis of the needs and characteristics of students at Jambi University Regular Physics Education Study Program (1) The teaching and learning process takes place in the lecture room.There is a lack of learning media that supports the learning process, especially in Geometric Optics material (2) Students already have the skills to use various electronic devices , computer or laptop.(3) The characteristics of students at Jambi University are diverse.
The formulation of this learning objective is based on the GBPP used by the Jambi University Physics Education Study Program.Based on the GBPP, the learning objectives are: a.General Instructional Objectives: After completing this lecture, students are expected to be able to apply various concepts of temperature and heat, thermodynamics concepts, concepts and properties of waves, optics, and basic physics in simple physics problems.b. Specific Instructional Objectives: Students are able to explain various Optical concepts geometrically which include the reflection of light in a flat plane, a curved plane (mirror), the refraction of light in a flat plane and a curved plane (lens).
The main points in this media include reflection of light on a flat plane, reflection of light on a curved plane (mirror), refraction of light on a flat plane and refraction on a curved plane (lens).The results are shown in the following pictures: The results of the validation of learning media for the Basic Physics II course with Geometric Optics material using professional Adobe Flash CS5 software by a team of experts in stage I can be seen in table 1 below: Based on the results of the media validation, the validator suggests improving the media in the following aspects.Material in the media, don't blame the concept.Use simplified sentences.Match the animation with existing animation descriptions.Tidy up the animation and captions.Use several colors and shapes in the media design and adjust the background to the title.material, Use animation that does not distort the concept, Set media colors that are appropriate and not dark, Writing is adapted to EYD and Indonesian and Simplified sentence construction.
After carrying out revisions according to the validator's suggestions in stage I, stage II validation was carried out again.Results of validation of learning media for the Basic Physics II course with Geometric Optics material using professional Adobe Flash CS5 software by a team of experts.From the results of stage II media validation, it can be seen that all validators have checked 'yes' on all aspects of the media validation questionnaire.This means that the learning media for Basic Physics II courses with Geometric Optics material using professional Adobe Flash CS5 software is declared suitable for use.

CONCLUSION
Designing learning media for Basic Physics II courses with professional Adobe Flash CS5 software on Geometric Optics material by analyzing student needs and characteristics, formulating learning objectives, formulating material points, compiling evaluation instruments, compiling media manuscripts/prototypes, carrying out expert validation, carry out trials and revisions.The learning media for the Basic Physics II course with professional Adobe Flash CS5 software on Geometric Optics material can be said to be in the good category.
