Application of Augmented Reality-Based Solar System Recognition Using Metaverse Studio

Learning media is currently developing with various innovations, especially in utilizing information technology. One of the technologies used for the learning process is Augmented Reality (AR). The purpose of the research is to provide alternative learning media using information technology, especially focusing on the use of AR. The learning that will be developed in this case is learning aimed at children to introduce learning about the solar system using interactive AR. The content of the learning media developed includes several things, namely learning the solar system and quizzes to test children's knowledge about the solar system. The research method used in developing learning media uses the Research and Development (R&D) method. The application development process can be done by adding features. The results of this study produce an AR-based application that describes learning the solar system in 2D/3D form and is equipped with a quiz to train children's knowledge.

1 Introduction 56 bonds, the periodic system and some other materials in 2D/3D form. The benefits of using AR can motivate students in learning basic chemistry. This is because students can interact with the developed application.
Research conducted by Rianto has developed an AR application to introduce traditional musical instruments, especially Lampung traditional musical instruments [6] .
The AR research used in addition to the learning model was carried out by Dwi.
In his research, he developed an AR application for building recognition. The usefulness of this application can be to introduce students to introducing building information on campus [7] .

Research conducted by Alifah developed an AR application about the Tapis
Fabric Textile Museum. This application is used to provide information about the collection of tapis cloth which is one of Lampung's cultures [8] .
Research conducted by Ilhami Arsyah developed an AR application for a 3D house model.
This application is used to help buyers find information on houses to be purchased and make it easier for home sellers as a promotional medium to consumers [9] .  [10] .
Research conducted by Avief Barkah & Agustina designed interactive learning media using AR technology for the introduction of temples in the Malang area [11] .
AR applications can be used as an alternative learning media to introduce the planets in the solar system to children. Applications built using AR technology that are simulated in 2D/3D forms can provide information to children about the planets in the solar system. Learning media packaged using AR technology can provide knowledge to children on the material being taught. The use of AR technology makes the material more The use of the Gometa application in the development of Augmented Reality as a learning medium has been carried out by Lestari [18] and Andika [19] . The research conducted by Lestari discussed the introduction of medicinal plant learning media and Andika's research explored the introduction of animals.
Based on the introduction and the literature that has been described in the introductory section above, in this study developing learning media applications that use information technology, especially focusing on the use of AR. The learning that will be developed in this case is learning aimed at children to introduce an interactive AR-based solar ssystem.
The content of the learning media developed includes several things, namely learning the solar system and quizzes to test children's knowledge about the solar system.
The application was developed using the Gometa online application to display objects in 2D/3D form. AR applications developed with Studio.Gometa.io can be seen using the Metaverse Studio application on smartphones.

Figure 1. ADDIE Stages in the R&D method
This research will produce an AR application that describes the planets in the solar system in 2D/3D form developed using the Gometa application. Fig. 2 display The results of the development of the Augmented Reality application using studio.gometa.io can be seen using the Metaverse application. Metaverse application is an android-based application. Fig. 3 Metaverse application display on android.

Linking Scene
The initial process of making the application begins with making information about the solar system in the form of a scene. Scenes that have been created will be assembled into one interconnected unit. The step to connect a scene with another scene is to select a button that contains a menu and is related or connected to another scene. Fig.   4, an example of a related scene.

Handling text input from the user
The developed application is also equipped with a scene containing a list of questions/quizzes. Before answering the question, the user must enter the name data. The process of designing input from the user uses the command / block save text feature. The process of using the save text block feature is shown in Fig. 5.

Figure 5. Handling text input
Handling text input from the user is by adding a block save text feature by connecting the display scene with the keyboard with the usual scene. In Fig. 5 above, between the 2 scenes, there is a save text block to retrieve the name data in scene 10 then it is stored with the name key in the save text block and the data is retrieved in scene 11 with the ${props.nama} command.

Creating a Quiz Scene
The purpose of the quiz scene is for users not only to study the solar system but also to work on questions to determine the extent of the child's ability to understand the material of the solar system. The process of making the scene is in Fig. 6.

Augmented Reality Application Results at studio.gometa.id
The solar system application design is designed and packaged in scenes. Scene contains data about the planets and each scene will be connected to each other to form a unified solar system application. An example of the front page of an application developed in the form of a scene is presented in Fig. 7.

Planet App Publication
The process so that the Augmented Reality application developed can be accessed by users by first doing the publishing process. The results of the publishing process are in Fig. 9.  The results of the scanning process, users can see the appearance of the solar system application in 2D/3D in Fig. 12.

Conclusions
Augmented Reality-based introduction to the solar system can be an alternative learning media. The use of AR is expected to make it easier for children in the learning process, especially the material to recognize and understand the planets in the solar system. The solar system augmented reality application was developed using the Gometa application. The development process is distinguished in the form of interconnected scenes and to see the results of the developed application, it can be seen using the Metaverse application on the smartphone.
