ABSTRACT
The aim of design and building Fisikandroid application is presenting an education application based on mobile android that contains physics formulas with more attractive material so it will easy to be understood by students. Trial application respondent is students of SMA N 2 Sukoharjo. Methods of data collection are questionnaire and comparison of pretest result. The end result of this research is an educational application based on mobile android that contains the physics formulas of class X, which presented more attractive and easy to be understood by students. It is proved from the questionnaire that 86.67% of respondents agreed if this application has elements of education, 96% of respondents stated this is an attractive application, 82.67% respondents agreed the information in this application is easy to understand, and 86.67% of students experienced increases in value after using this application which means that this application can improve students understanding of the material presented.

INTRODUCTION
The development of information systems and technology are now growing rapidly (Supriyanto, 2005). Along with the development of these technologies, an
A smartphone is supported with a default operating system, one of the operating systems that is growing now is the android (Safaat, 2011). Android is an operating system for smartphones which is developed by Google. The open sources have the impact on the increasing number of users and developers significantly (Huda, 2012).
Physics is one of sciences that studies the universe. Due to the implementation of physics are found in everyday life, physics becomes the basis for future technological mastery (Indrajit, 2009). Conceptually, physics contains many formulas that make students are not interested to learn or memorize and understand it. Moreover, the complicated questions cause physics becomes the difficult subject (Sugiharti, 2005). Because of the reason, presenting the materials and physics formulas attractively and colorful with additional video animation are attempted to increase students’ interest in
learning physics and to make the students more understand the materials.
Therefore, the author raised the title “Physics Formula Application Based on
Mobile Android for Tenth Grade High School”.
LITERATURE REVIEW
According to Wijaya (2012), in his journal entitled "Aplikasi Kimiandroid Pada Ponsel Berbasis Android ",
kimiandroid application is an educative application to help the learning activity, especially in chemistry. Kimiandroid
application had been tested, and it could run quite well on the Samsung Galaxy Mini GT-S5570 Android operating system 2.2 or Froyo (Frozen Yogurt).
Meanwhile, according to Aripurnamayana (2012) in his journal entitled "Rancangan Dan Pembuatan
Mobile Learning Berbasis Android (Studi Kasus: Pembelajaran Sejarah Di Smp)", some alternative methods in relation with the modification in teaching history need to be developed. One of the methods that I think could be applied is the use of audiovisual media via mobile learning. The purpose of this study is to develop eighth grade students’ interest in history and as the
interactive media in learning history which is more interesting. The try out had been done on the emulator 2.1 and emulator 2.2. The program implementation was done on has faster speed access.
In manuscript publication entitled
"Perancangan Aplikasi Rumus-Rumus
Fisika Berbasis Android" compiled by Latif (2012) said that to make it easier for students to learn physics formula, then it needs a new method which is easier and more enjoyable so that it can increase students’ interest in learning. Learning
media that are moveable (easy to carry around) would be more effective. The design of this Android system was accomplished by designing the UML, using case diagrams, class diagrams, and sequence diagrams, designing ERD, designing database, and designing graphic. The results of this study is the use of mobile media in conveying information about the discussion of physic materials such as
massa jenis, kalor, pemuaian, kelajuan,
There is also a menu of test questions used for exercising after learning or reading material.
In the journal entitled "Rancang Bangun Model Pembelajaran Fisika SMA
Dengan Flash (Studi Kasus Gerak Benda)"
by Santi, et al, (2009), the multimedia aspects supported an application in the manufacture of instructional applications. This was because multimedia was the integration of audio, video, text, animation and graphics in a digital interactive environment. This study built a Physics Teaching Tool Application using Macromedia Flash 8, which can assist in the learning process. This study provides a good interface learning materials which is user-friendly and also creates a way to keep children from the saturation while studying.
RESEARCH METHODOLOGY
a. SDLC (System Development Life
Cycle)
The research method used is SDLC (System Development Life
Cycle), a method that describes the system development life cycle in the design and development of information systems. SDLC has had several phases, starting from beginning stage up to the last stage and back again to the beginning stage form a cycle or life cycle (Jogiyanto, 2005).
Figure 1 Flowchart SDLC
The stages of SDLC methods are: 1. Requirements definition stage was
was also conducted to allow an designing the user interface which includes appearance, content and the design of Physics Formula Application Based on Mobile Android for Tenth Grade High School complete with the exercises and evaluation to measure users’ level of understanding the material. 4. System development stage or
program coding was the implementation phase of the design stage done by using a supporting software programmer. This
instructional media application development used Eclipse Helios 3.6.2 software.
5. Testing system was the try out or testing stage of the learning media
application before the application can
be used fully. The purpose of testing
was to make the system run smoothly
and free from errors, and the result can
be accordance with the design and user
needs.
b. Designing
The UML designing only includes the Use Case designing. Based on the analysis of learning needs of the media system, a use case of the system that will be built can be made. The Use case itself includes, use case diagrams, actor definitions and use case definition. 1. Use Case Diagram
Use case diagram is used to illustrate the facilities given by this application for the users. The users consist of teachers and students. "Figure 2 Use Case Diagram" explains that the user as an operator get the full facilities to open and operate any information and evaluation exercises provided in the
Fisikandroid application. This application has a static character and not uses the database as the data storage media so the user cannot change the content of information and practice questions.
2. Actor Definition
Describes the facility that can user get from Physics Formula Application Based on Mobile Android for Tenth Grade High School. User is the people who have to access the information of application and do the exercises and
evaluations that are available in the application.
3. Use Case Definition
The following is the use case definition that includes Physics formula materials and evaluation. a) Physics Formula Materials
In this section the users can open the materials of physics formulas with example of the questions.
b) Exercises and Evaluation Test In this section the user can do the exercises and evaluation to measure the level of understanding of the material.
application while operating, as well as make improvements performance less than the maximum.
2. External
External testing in this research divided in to three ways there are by comparing the exercises result before and after using this application, by using questionnaires and by testing the system itself. Formula to calculate score of questionnaires
Ideal Score / Maximum Score
(SMax) = 5 x n = 5n (SA) Minimum Score (SMin)
1 x n = n (SDA) n = total respondents
Score (S) = ∑ (Total Respondent Answer Voters x Weights Answers) Interpretation percentage (P) percentage rate of Interpretation (P), i.e. the interval scales (Riduwan et al, 2007) as follows:
81 – 100 (very strongly)
