Abstract: Diet is a control of eating habit for someone to achieve the objectives of the diet itself, either to lose weight

or to gain weight. The number of calories from the food we eat every day, determine whether a diet that we

do may lose body weight or increase body weight. But not everyone can control their daily calorie

consumption, because of that, many people have problems of overweight or obesity. Therefore, a mobile

application that can calculate a person's daily caloric intake, can help someone to achieve their diet goal.

The research purpose is to make a mobile calorie counter application based on Android operating system.

The application is developed using a Rapid Application Development (RAD) methodology, the Java

programming language has been used to develop the system, while SQLite has been used for database

development. This application can run offline without an Internet connection. This application has five main

features, namely the body mass index calculator, total daily energy expenditure counter, the body fat

calculator, daily calorie intake counter and foods calorie list. Therefore, user can get a variety of information

about diets and calories, so it can help them to achieve their weight loss goal.

1 INTRODUCTION

In the modern society, many people who work in an

office environment prone to suffer an obesity (Kania,

2014), due their working habit of sitting in front of

computer all day.

According to Dr. Ita Muharram Sari SPS as a

consultant of the meetdoctor.com, office work

patterns that require workers to sit for hours,

becoming one of the factors of their lack of physical

activities. The difficulty of controlling their diet and

lack exercise has an impact on the many people.

Because of bad diet and lack of exercise, many

people suffer from overweight and obesity.

Lack of knowledge about a healthy diet is also

the cause of overweight. Whereas all the necessary

resources can now be accessed easily. Developments

in information technology should help solve this

problem. With the rise of communication devices

usage, every people now can access all kind of

information.

Now lot of people already owned a mobile device.

According to eMarketer in 2014, mobile phone users

in Indonesia reached 38.3 million users. Cell phone

or mobile phone is now progressing very rapidly (H,

2012). Initially, a mobile phone may only be used to

make a voice calls or send and receive short

messages. But everything is change after discovery of

smartphones. Therefore, development of an

application to help people learn a healthy diet,

exercise and a way to help them losing weight can be

done.

2 RELATED WORK

There are many similar works which research on

mobile health information systems for example (Rao

& Krishna, 2015), they proposed a design of mobile

health for android applications. In (Hariadi,

Khotimah, & Wiyono, 2015) and (Doukas, Pliakas,

& Maglogiannis, 2010) also proposed a nutrition

information systems mobile based.

2.1 Body Mass Index (BMI)

The number of calories from the food we eat every

day are determine whether a diet that we do can lose

weight or increase weight. Basically, to achieve a

weight loss then one must adjust the diet and daily

routine, so that the calories used by the body is more

than the calories absorbed by the body. When the

calories taken into the body is greater than the

calories used by the body to eat excess calories will

be stored by the body in the form of fat reserves,

which will have an effect on a person's weight gain.

The first thing to be done to determine that a person

has a healthy weight or not is to calculate the body

mass index (BMI). BMI is the ratio of weight divided

by the square of one's height, which can be calculated

as (Budianto, 2010):

(1)

Generally, the result will be of little value for

skinny people and has greater value for obese

people. Classification of value can be seen in the

following table:

Table 1: BMI Table

BMI Clasification

< 14,9 Severly Underwight

15 - 18,4 Underweight

18,5-22,9 Normal

23 - 27,5 Overweight

27,6 - 40 Obese

>40 Severly Obese

2.2 Basal Metabolic Rate (BMR)

After calculating the BMI, then we know the

condition of our body. Next stage is to calculate the

daily calorie intake of our body by using the BMR.

BMR is the amount of energy or calories needed by

the body in a state of rest. So at the moment we do

not indulge the body also requires a certain amount

of energy or calories to use to keep our body function

properly. The number of calories or energy is only

able to run the organ - a vital organ in our body. The

higher the person's body muscle mass, the higher the

energy or calories your body needs to keep it in a

stable condition.

There are several formulas for calculate these

BMR. This time it uses the Mifflin-St Jeor equation.

This equation can be seen in the formula 2 (Budianto,

2010).

(2)

BMR calculations are different for each person

depending on their physical activity. Therefore to

get the more precise calculation, the results of BMR

calculation using the table above should be

multiplied by a factor of activities in accordance

with daily activities - day, i.e:

 1.2 for people who are inactive (little or no

exercise at all)

 1.375 for people with mild activity (light work

or exercise 1-3 times a week)

 1.55 for people with moderate activity (work

is being or sports 3-5 times a week)

 1.725 for active people (heavy work or

exercise 6-7 times a week)

 1.9 for people who are extra active (very hard

work or jobs that require heavy physical

labor)

2.3 RAD Method

System development method that being used is RAD

(Rapid Application Development) (Kenneth E.

Kendall & Kendall, 2007), This model was made by

James Martin to make the system faster without

compromising quality (Pressman & Maxim, 2014).

3 SYSTEM DEVELOPMENT

3.1 Requirements Planning Phase

3.1.1 Selecting Gather Information About

Diet

The purpose of gathering information about diet are

as reference information about what is needed in the

process of weight loss. What should be known about

the user's body calories needs and calories from

foods and beverages consumed. So that the authors

can present information in accordance with user

needs to support weight loss program (Kumalasari,

2008)(Samudra, 2013). The authors conducted a

search of information by spreading the questionnaire,

seeking information from the Internet, the authors

also do direct observation by executing the process

of weight loss.

3.1.2 Questionnaire

At this stage the researchers made a survey

questionnaire. The questionnaire contains 14

2541

questions relating to the behavior of respondents in

the diet. Of the 38 respondents was only 11 people

(29%) who know the needs of daily calories, and

only 9 (24%) who know how to calculate daily

caloric needs of the body. Number of food calories

are important for regulating a person's weight, but

based on the questionnaire only 8 people or 21% of

the total respondents know the calories of food they

eats. From the results of the questionnaire author can

know the needs of the application features.

3.1.3 Identification of Application’s

Features

The next stage is to identify what features are needed

inside the application. Based on the collection of

information through observation and questionnaires,

the authors conclude that the features that are

required are as follows:

 Features of the user to store the required

information, such as weight, height, and age.

 Features to calculate body mass index (BMI)

 Features to calculate daily caloric needs of

the body.

 Features to calculate the amount of body fat.

 Information on calorie foods and beverages.

 Features to display information about the

number of calories that have been consumed

by the user.

 Record or log of food and drinks that have

been consumed.

3.1.4 Requirements Identification Prototype

System Requirements

 The application is able to

provideinformation about the daily caloric

needs of the user easily.

 The application is able to provide

information about the foods’s and

beverage’s calories that user consumed

based on database of food and drinks

provided.

 The application is able to provide

information about calorie of foods or drinks

based databases provided

3.2.3 Construction Phase

At this stage, the coding of the design of the system

have been performed. The Java programming

language has been used to develop and XML has been

used to display the layout. The authors use SQLite as

a database, it is because SQLite is available by default

on android, and can be used easily by simply import

them as a library in the android development tool

(ADT) (H, 2012). Applications used as ADT is

Eclipse Juno with support of Software Development

Kit (SDK).

3.3 Implementation Phase

Before the application is implemented directly on the

android device, the application must be free of bugs.

The bug could occur because of an error when the

application coding, logic errors, or also can be caused

by devices that do not support.

In this phase there are some steps done, namely:

 Write Java source code, at this stage the tools that

being used is the application development

software for Android, the Android Development

Tools (ADT) in the form of Juno Eclipse and the

Android Software Development Kit (SDK).

 Packaging process data by using the facilities

provided by SDK and Eclipse.

 Running the application on android device, to

perform testing on an android device directly,

and make repairs when needed.

4 CONCLUSION

4.1 Conclusion

Based on the research and design of this, it can be

concluded:

 This application is designed to help users to

determine the condition of the body, as well as

the number of calories needed to tell users how

much calories from food eaten.

 The application is designed using eclipse

program, and runs on smartphones that use the

Android operating system.

4.2 Future Works

Applications built certainly still have many

shortcomings, therefore there are some things that

might be developed for these applications to be better

and more useful, namely:

 Applications can be developed so that it has an

online update system. System update function to

add food database and data on the number of

calories contained.

 Applications are still running on the Android

operating system only. For future development

may be made on other operating systems (e.g.

IOS).

 Added a menu that gives information about the

types of diet that exist, and how to run it.
