INTRODUCTION

The development of information

systems and technology are now growing

rapidly (Supriyanto, 2005). Along with the

development of these technologies, an

information is not only accessible by using

a PC or laptop media, but it can be accessed

only by using a phone that people often call

it a smartphone.

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 was built in several stages. First,

it was started with designing the UML

which was Use Case Diagram, Activity

Diagram and Sequence Diagram. And then,

it was proceed with designing the

appearance and building the program by

encoding the program in Eclipse. After that,

compilation and implementation using 2.2

AVD were done. This application was also

expected to enhance the students' interest in

learning, particularly in chemistry. This

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

the Samsung Galaxy Mini. In general, the

results showed in the emulator and Galaxi

mini were not much different from the

results showed in emulator 2.1 éclair.

However, Android with a higher version

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,

usaha dan gaya may provide a

breakthrough for the users to learn physics

formulas briefly anywhere. There is a

calculator menu to perform calculations.

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

the planning process of the

introduction application and

learning needs and the potential

user. Verification of problems

occurred before the introduction

application and learning were built

was also conducted to allow an

assessment for the new

requirements.

2. Requirements analysis stage was to

find and analyze user reqirements

both in the form of information or

devices used and the applications

align with user needs, and then

provide the best alternative on the

application used by the user to

facilitate user performance.

3. Planning or designing stage was

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

Figure 2 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.

c. Testing

The tests performed after the

system was completed. It is conducted

internally and externally.

1. Internal

Internal testing is conducted by the

researcher, in the form of error-

checking applications, the smooth

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)

Where the each of weight answer

are:

SS : Strongly Agree (5)

S : Agree (4)

N : Neutral (3)

TS : Disagree (2)

STS : Strongly Disagree (1)

Furthermore, to measure the

percentage rate of Interpretation (P),

i.e. the interval scales (Riduwan et

al, 2007) as follows:

81 – 100 (very strongly)

61 – 80 (strong)

41 – 60 (enough)

21 – 40 (weak)

0 –20 (very weak)
