I. Introduction
The Information Technology study program laboratory is a place of practice for Information Technology study program students located on the 3rd floor of the Aceh Polytechnic Campus and has 12 different laboratory rooms with different functions. Not only that, this laboratory is also often used by guests as a place for training and testing. However, to see the contents of the laboratory room in the Information Technology Study Program in detail, guests must enter the room to see the details of the room. With the creation of Augmented Reality media, it is expected that guests who use the application can see detailed information on the laboratory room and can see three-dimensional objects in the laboratory room like the original and with this innovation, it is expected to add to the attraction of guests to visit the Aceh Polytechnic campus.
Recognition media that can display three-dimensional objects that are almost identical to the original are needed to make it easier for guests to see the laboratory rooms in the information technology study program. So guests can see three-dimensional objects in each room with Augmented Reality technology. Augmented Reality (AR) can combine virtual objects into a real three-dimensional environment and then project these objects into real time.
II. The Proposed Method/Algorithm A. Flowchart
Designing an application that will display 3D objects in the Information Technology study program laboratory space using Augmented Reality technology. The first thing to do is make a flowchart, create laboratory room objects, prepare supporting tools for Augmented Reality, and

Article history:
Accepted The Information Technology Study Program laboratory, located on the Aceh Polytechnic campus, is a place of practice for Information Technology Study Program students. This laboratory is often also used by guests for training or testing. Therefore, to make it easier for guests to see the details of the room, an Augmented Reality application for the Android-based Information Technology study program was built as a promotional tool and learning media. This application makes it easy for guests to find out the shape of the room, find out the contents of the room and explain videos about the Information Technology study program using a smartphone. Making this application using Blender software is used to create a three- dimensional model of the room, while Unity software is used to create applications.

make a catalog as a tool for Augmented Reality applications later. This application is made using the C # programming language (pronounced: C Sharp).
Fig. 1. Flow chart (Flowchart) Flowchart Description
1. Start When run it will go to the main menu.
2. Main Menu The main menu display has four menu options, namely: Start AR menu, Help menu, About menu, and Exit menu.
3. Scan marker If the user selects this menu, the program will process it to display 3D objects that will be read by the marker that has been designed. On this menu the program will search for the markers that have been provided, if the marker is found then the application will identify the three-dimensional object from the marker, if the marker is not found then the program will continue to look for markers to display the object. If the identification is successful then the program renders the object, this is the process before the program displays a three-dimensional object from the marker. After the program finishes rendering the object, the program will display a three-dimensional object and will display a detailed description of the object.
4. Help If the user selects the help menu, the application will display a page which contains an explanation of how to use the application.
5. About If the user selects the about menu, the application will display information about the application.
6. Exit If the user selects this button, it will exit the application.
III. Method
The method used in augmented reality technology is as follows:
3.1 Marker Based Tracking Method
This method uses illustrations that are black and white and square in shape, and have bold black borders on a white background. In the marker based tracking method, three axes will be used, namely X, Y, and Z with the help of coordinate points (0, 0, 0) and also virtual in 3 dimensions. Here the author uses the Marker Based Tracking method because the marker based tracking method is more suitable for displaying 3 dimensional objects and marker shapes that are easy to recognize by the camera user. A marker is a picture (image) in black and white with a square shape. The computer will recognize the position and orientation of the marker which will create virtual objects in the form of 3D objects[1].
In designing this application, the author uses Blender 3D software to design 3- dimensional space objects which will later be implemented into the application. The features that the writer uses are available in the Blender 3D application itself, making it easier for the writer to design 3-dimensional objects.
3.2 Androids
Andriod is an operating system for Linux-based mobile devices issued by Google Inc. in November 2007. This operating system is open source so that developers can create their own applications for mobile devices as needed[2].
In making this application, the author uses an Android smartphone as a tool to help display and project the Augmented Reality object of the Information Technology Study Program. This application will use the camera on an Android smartphone to display 3- dimensional objects that are late designed in the real world environment.
3.3 Unity
Unity 3D is a game engine software for building 3-dimensional games. The Unity application in application design is used so that the augmented reality application that will be designed can be implemented into an Android smartphone and displays 3- dimensional objects based on each marker that has been designed. With the features that are already available, it will be implemented with 3-dimensional objects that have been made before[3].
3.4 Vuforia SDK
The Vuforia SDK is an augmented reality-based Software Development Kit that uses the screen of a mobile device as a "magic lens" or glass to see into the Augmented world, where the real and virtual worlds appear side by side. This application creates a camera preview directly on the smartphone screen to represent a feature view of the physical world. 3D objects will appear directly on the smartphone screen, so that 3D objects can be seen in the real world. The Vuforia SDK consists of 2 main components, namely the QCAR library and the target management system[4].
3.5 C#
C# is a programming language a new product created by Microsoft which was developed under the leadership of Anders Hejlsberg who has created various programming languages including Borland Turbo C++ and Borland Delphi. C# language has also been standardized internationally by ECMA. As with other programming languages, C# can be used to build various types of applications, such as Windows-based (desktop) applications and web-based applications as well as web services-based applications. C#
was designed to meet the need for a more concise C++ syntax and a 'limitless' Rapid Application Development compared to the 'limited' RAD as found in Delphi and Visual Basic. C# is also one of the programming languages supported by Unity apart from two other languages, namely Java and Book[5].
IV. Results and Discussion
After carrying out the planning stage up to testing, it can be concluded:
A. Main Menu Display
On the menu display there are 4 buttons namely Scan Marker, Help, About and Exit. Scan Marker button to move to the AR camera page, Help button to move to the Help page, About button to move to the About page, and Exit button to exit the

V. Conclusion
After carrying out the planning stage up to testing, it can be concluded:
1. This application can help guests get to know the Information Technology study program laboratory and the objects in it.
2. This application is useful as a promotional media for Information Technology laboratories in the form of 3D Augmented Reality animation.
3. This application is an alternative learning media.
