ABSTRACT
The 3-dimensional animation designed and presented as learning media has grown rapidly nowadays, 3dimensional animated characters in regional musical instruments can be one of the learning media for the general public especially children.
How to present different learning 3-dimensional animation content, can attract the general public and children to learn, one of them using augmented reality technology.
Augmented reality is the practice of combining image media with a 3-dimensional object that brings out 3- dimensional objects from cyberspace to the real world.
This way can be a form of learning, where users can see and understand that learning can be conveyed through efficient learning, in the concept of augmented reality, users not only play with this application but can Learn knowledge about regional musical instruments in Indonesia.
Development of the learning system of Multimedia applications regional musical instruments in Indonesia using Augmented Reality technology is able to provide knowledge in learning that is not only in general public but also for children Children who want to add insight into the knowledge of regional culture art, especially local musical instruments in Indonesia.
Keywords: Multimedia Learning.

INTRODUCTION
The Indonesian nation is a very large nation with its diversity with ethnic, cultural, language and religious In this diversity.
Indonesia is a country that is very rich in the uniqueness of it.
Technology is a tool that many people use to facilitate and fulfill their individual needs.
Augmented Reality (AR) is a technology that combines two-dimensional or three-dimensional virtual objects into a real three-dimensional environment and then projects the virtual objects in real time .
Nowadays AR is growing and start many applications and libraries that can be used to develop AR.
The less interest in learning the general public especially children due to the development of entertainment technology that precisely Increasingly presenting interesting and interactive things such as cartoon movies and 3D While the learning media that is currently used is still dominated by books that contain writings and drawings only.
Technology 3D image is widely used for the entertainment industry that is indeed more attracting interest from children and the general public.
With the existence of AR technology, materials in the educational world that looks boring can be simulated and created 3D objects so that the general public especially children can directly interact with the AR object.
The use of an Augmented Reality technology-based trainer is very useful in enhancing the teaching learning process because Augmented Reality technology has entertainment aspects that can inspire learners to understand of material delivered through 3D visual representation by involving user interactions in Augmented Reality It is hoped that the learning Media application of regional musical instruments in Indonesia using Augmented Reality technology can create new learning tools and methods to understand Indonesia's custom and culture.
Interactive and interesting and can help convey information about regional musical instruments in Indonesia.

SYSTEM ANALYSIS AND DESIGN
In designing this application the author uses a system modeling language called UML or Unifide Modeling Language consisting of Use Case diagrams.
Activity diagrams.
Class diagrams, and Sequence diagrams.
Here's a description of the UML or Unified Modelling Language.
USE CASE DIAGRAM
Here is a view of Use Case diagrams Media Application Learning local musical instruments in Indonesia using Augmented Reality technology :
Figure 1.
Use the system Diagram Case In Figure 1 Use Case Diagram, this section describes each description of the Use Case Diagram performed by a user/user.
Start from the process of selecting Start Scan, help, about, and exit.
Users start to log in using the application and the system will perform marker detection.
Once the marker is found then the system renders the object.
In the Help menu will be displayed page how to use this AR application.
While on the menu about the AR application will be in display information about the developer of the application.
The exit Menu is used if the user wants to exit the USE CASE DIAGRAM Figure 2.
Activity Diagram In Figure 2.
Activity Diagram, the activity process of the Start menu diagram scan starts when the user opens the application by tapping the app icon, then the system displays the app's home page.
After that the user selects the Start menu scan, then the system detects the camera.
If the camera is not detected then the process is complete, while if the camera detected the user will show marker.
If marker is not shown then the process is complete, while marker indicated system detects marker.
If the marker is not detected the process is complete, whereas if the marker detected the system will render the object.
The object and sound will display if the system finishes rendering the object.

CLASS DIAGRAM
A diagram Class is a specification that if an instantiation will result in an object and is the core of an objectoriented development and design.
The Class describes the state .
ttribute or propert.
of a system, while offering a service to manipulate that State .
ethod or functio.

SEQUENCE DIAGRAM
Figure 4.
Sequence Diagram In Figure 4, described smartphone will detect the camera, if it has been detected then the user will show the marker book towards the camera, then the camera will look for objects in the database, if available, it will render the object then displayed into 3-dimensional object on the smartphone screen.
SYSTEM IMPLEMENTATION
1 System Analysis System analysis is the development of early phases used in decrypting and elaborating the whole parts into the Components section in order to identify and evaluate an application to know the barriers Happen.
And the expected needs of the learning Media application of regional musical instruments in Indonesia using Augmented Reality technology can run in accordance with its functions.
2 Hardware Based on the literature study on AR technology development projects, the minimum hardware specifications required by the developer for AR technology are as follows:
Processor Intel Core i3 or so on.
II.
Minimum RAM 2 GB i.
Optimum uses VGA Card with the ability to render 3D graphics, such as Nvidia GeForce 6x or ATI 1x While the minimum hardware specifications required by the user for the AR technology are as follows:

Smartphone or tablet with the minimum Android operating system Jelly Bean.
It has a camera to capture imagery that is then processed by applications already installed on the smartphone and has a minimum RAM of 2 GB.
3 SOFTWARE
The software required by the developer tbuild the application is as follows:
Windows 10 Home Operating system.
Blender 3D Animation.
Vuforia SDK dan JDK.
Unity 3D
Photoshop 2020
CorelDraw
Wondershare Filmora
OBJECT IMPLEMENTATIONS
After analyzing the system, the next step is to implement 3D objects using Blender 3D and Unity 3D software.
Blender Application used is Blender 3D.
This 3D object creation implementation uses blender 2.
79 software.
Following is the image that generates the implementation of 3D object creation in the blender.
In Figure 6 is 3D object modeling from regional musical instruments in Indonesia using Blender 2.
79 software.
The first step is to create a 3d object from a hand.
The hand 3d objects function to create moving animations like playing a musical The object created originally was just a plain texture with no color.
Here's the 3d object view from hand.
Figure 5.
Hand Objects 3D After creating the hand 3d object, then the next step creates a 3d object from the musical instrument.
Here's an example of one of the 3d objects from a siter instrument.

After the 3D object modeling stage, the next step is to make the process of adding skins to the 3D object and imported into the prepared Unity project.
Figure 7.
Imported 3D Object display Figure 7.
It is a 3D object that has been imported into the Unity project.
At this stage there are also several settings to adjust the layout of the 3D objects, the direction of the camera, and the lighting.
USER INTERFACE IMPLEMENTATIONS
The design of an application display interface from the Learning Media application of regional musical instruments in Indonesia using augmented reality technology is implemented using the features found in Unity 3D.
