1. Introduction

The development of information technology (IT) is more advanced and growing. It is also accompanied by the increasing needs of the community for technology and information. The information received is easily accessible from various locations, which can also be easily consumed by the community through technology. The development of multimedia technology also quickly offers a major change in the current human lifestyle [1]. Another supporting factor is the increasing use of smartphones, especially those based on Android. The Android operating system is an operating system on smartphones that are freely available for commercial or noncommercial use [2]. The Android operating system was introduced in 2008. Android continues to grow because it has advantages of open source and Android also offers many tools for building software that offers possibilities for application development [3].

Currently, the learning media for children in Android software is still limited such as learning letters, numbers, animals, and simple calculations for children. These apps usually offer only one learning material, such as an app for learning a letter or an app for learning numbers. Seeing these conditions would be better if learning materials are combined and used as a medium of learning for children, to facilitate the children learn letters, numbers, animals, and simple calculation [4]. Therefore the application built under the name “Homy Kid Lesson” by providing features with music and animation to help children recognize letters, numbers, and animal names in a fun way, and also do simple calculations (addition and subtraction) of course with interesting and interactive images. The goal of this Homy Kid Lesson application to help the children to know numbers, recognize letters, recognize animal names, and to perform simple calculations. The benefits of this application increase the ability of children to recognize letters and numbers early, increasing the knowledge of animal names, introducing how to spell the letters and numbers to children also train the child’s ability to simple counting and introduced the method of learning with electronic media.

2. Methodology

Mobile learning in pre-school education has potential benefits suggested by Mike et. al [5]. With the implementation of a systematic study, researchers wanted a positive impact on the use of mobile devices and ICT (information and communication technology) in kindergarten, not only of computers in the classroom but also on the technology used to assist teachers. The main concern is how to maximize the benefits of this instrument to improve the children’s experience of ICT in education.

Mobile application for teaching mathematics has been proposed by Zaranis et. al [6] in kindergarten to helps students more active in learning and improve their initiative and opportunity for self-study. It shows that mobile application is very effective in increasing the motivation of kindergarten students for this is the position of kindergarten students to organize what, when, and where they learn. It becomes an easy platform for learning.

The basic functional requirements for mobile apps for children with special needs is proposed by Kraleva et. al [7]. This issue became very important in the last years because an increase in the number of children with special needs on a worldwide scale is observed and at the same time the increase in the use of mobile technologies.

Research design-based method proposed by Soykan et. al [8] developed for students and teachers in teaching concept skills to develop disabled students and to examine the process of developing software based on the infrastructure of operant conditioning theory. Their design-based research method developed for students and teachers in teaching concept skills to developmentally disabled students and to examine the process of developing software based on the infrastructure of operant conditioning theory.

Analysis of this type of application is done by analyzing similar apps that have been developed before. It gets an overview of these applications and gets additions so that apps can be made better. A comparison of these applications is shown in table 1.

Table 1: Comparison with Similar Applications

The development combines three different levels for the system integration, framework, and structure of the game. On a conceptual level, a game is considered as a system (i.e. a set of interrelated elements). A game is designed by specifying certain relevant factors, taking into account the two fundamental dimensions of space and time: the space dimension overs the static configuration of gaming locations (virtual) and includes associated objects, attributes, and relationships, and its evolution over time covers the game dynamics. On a technical level, the framework describes the basic architecture of the game development system which describes the system and its tools for developing the places, objects, actor roles, and scenarios of the video game. On a practical level, i.e. the structure of the game, the options offered to the players, and the multimedia representation of the game environment. The research method used in this study is shown in Figure 1.

Figure 1: The research method used in this study.

The proposed app uses a model of Agile Extreme Programming (XP) [9], which has stages of development as follows: Planning, that focus to get an overview of the functions and application software through communication with the user. This phase consists of several parts: literature studies, questionnaires, interviews, and analysis of similar applications. Results of communication with the user later collected in an index of stories in which each point of the index is determined to build priorities. The design stage aims to build the pattern of the logic of a system based on a result of communication with the users. It provides a kind of design in the development of applications, namely the application design, system design using CRC maps are then formulated in UML9 also build user interface design using a storyboard. Coding, first make a unity check to test the system to be implemented and write application code on the XP model applies the concept of paired programming. Testing at this stage on XP also carried out at the coding stage is with unit tests. After each module in the unit test, the final process test this application by using Eight Golden Rules Theorem [10] as an acceptance test.

Based on the results of the questionnaire and the questionnaire obtained, several conclusions can be drawn. Most respondents agreed that the introduction of numbers, letters, and names of animals is important for young children. Most respondents agreed that early childhood children should be taught simple calculations (addition and subtraction). Some respondents answered that the method of learning while playing is very well used in providing educational insight to early childhood. Some respondents think that the application of education can help in providing educational insight into early childhood. Respondents on average agree that the educational applications of mobile devices can increase interest in learning in young children. The average respondent said that the age range of 3-5 years is the ideal age to provide educational insight to early childhood because in this age range the child is experiencing growth and development which is often referred to as “Golden Age”. Respondents said that to increase motivation to learn in young children must be done with an attractive and attractive environment as well as a supportive environment. Respondents gave positive responses to educational applications that could help in providing educational insight into early childhood. The app will add music and animation functions to make it easier for children to recognize the letters, recognize the numbers. It will add animation to introduce the names of the animals. The survey results showed that as many as 105 respondents answered that letter recognition is important for early childhood. With so many respondents assessing the importance of this, the application will present a letter recognition feature for toddlers. As many as 105 respondents answered that the recognition of numbers is important for early childhood. With a fairly dominant number of respondents, this application will present a number recognition feature for young children. The survey results showed that as many as 105 respondents answered that the recognition of animal names is important for early childhood. With the results obtained, the application will present the name recognition feature for early childhood. The survey results showed that 77 respondents answered that early childhood should be taught simple calculations. From the viewpoint of quite a lot of respondents, the application will present a simple calculation feature for young children. Figure 2 shows the use case for the application.
