An Augmented Reality Virtual Guide Museum Multatuli Rangkasbitung Based on Android

— Multatuli Museum has been established for several years and is visited by many tourists. However, in practice the Multatuli Museum often lacks museum guides when there is an increase in visits, so that visitors who are not accompanied by a tour guide do not get complete information. In addition, the lack of interest of the younger generation in visiting museum attractions so that by applying Augmented Reality technology to the Multatuli Museum is expected to attract visitors, especially the younger generation. Augmented Reality (AR) is a technology that is able to insert 3D and 2D objects into a real environment in real-time to display a Virtual Guide at the Multatuli Museum. The author creates an animation in the form of a virtual guide for the Multatuli Museum using Blender software to create 3D animations and using Unity software to build the application as well as the Vuforia extension for Unity with C# programming language. The author uses the prototyping method as the application development method and uses the Unified Modeling Language (UML) as the system design. This research produces an Augmented Reality Application that can be used on Android smartphones. This application is capable of displaying 3D animations that provide information about the showrooms in the Multatuli Museum. Based on black box testing all features in the application are 100% running well. with this application visitors feel helped when the tour guide is limited and feel happy because there is still a Virtual tour guide who helps in the museum.

INTRODUCTION Technological developments are currently developing in all fields, including tourism, and one of the technologies currently developing is Augmented Reality (AR) Technology which is entering a new phase that allows for increased user experience to the perception of reality. Augmented Reality (AR) is a combination of real and virtual objects in a real environment, running interactively in real time and there is integration between objects in three dimensions, namely virtual objects integrated in the real world. [1] [2]Information about objects and the environment around us will be added to the Augmented Reality system, which will then be displayed on the real-world layer in realtime as if the information is real. [3]Then, these virtual objects are projected in real time directly through media in the form of markers or markers directed at the camera. [4]The Multatuli Museum is one of the museums in Rangkasbitung, Lebak Regency, but when visiting the Multatuli Museum visitors have difficulty finding information about the available showrooms because there is no tour guide in the museum, there is only one officer who receives visitors. A Tour Guide is a person who provides explanations and pointers to tourists and other travelers about everything that they want to see, witnessed by the tourists concerned when they visit a particular object, or area. [5]In addition, the lack of interest of the younger generation, especially in Lebak Regency, in visiting the Multatuli museum is one of the factors for the lack of visitors to the Multatuli museum.
Based on the above background, the author develops and implements an Android-based Augmented Reality Virtual Guide Museum Multatuli application. Android is an operating system developed for Linux-based mobile devices. [6]This application is developed uses Blender software to create 3D animations, Unity software to build its applications and Vuforia Engine extensions the most widely used platform for AR development, with support for phones, tablets and VR glasses with C# programming language. [7]The system development method used is a prototype which is a system development method where the results of system analysis are directly applied to a model without waiting for the entire system to be completed, producing a prototype of the software that is used as an intermediary between developers and users to interact. [8]System design using UML (Unified Modeling Language) is a language based on graphics/images for visualizing, specifying, building, and documenting a software development system based on OO (Object-Oriented). [9]In this study, the authors started the stages of data collection through observation, design, implementation and testing. The test used is Black Box testing is a software testing technique that focuses on the functional specifications of the software. [10]In addition, testing the quality of the system that was built was done by distributing questionnaires to respondents, managers and visitors to the Multatuli museum.
The research used as a reference is research [11]Augmented Reality-Based Learning Application in the Wudhu Guide for Children, this application is able to increase the average value of student learning outcomes. Study [3]Application of Augmented Reality Applications for Android-Based Baby Stimulation Recognition, this research is able to make it easier for parents to stimulate their babies properly. Study [12]Application of Augmented Reality Technology in Android-Based Home Catalog Applications. This study concludes that this application makes it easier for buyers to see a house virtually in the catalog provided before buying a house. Study [1]Augmented Reality Markerless Tour Guide System Utilizing GPS Based Tracking With Android Platform". This research provides ease of use and can be used anywhere because it is applied in Android smartphones. As well as research [13]Tour Guide Application Using Android-Based Location Based Service (LBS) Method (Case Study in Ende Regency -East Nusa Tenggara). The result of this application is that it can provide directions or routes to tourist sites, hotels, and restaurants in Ende Regency.
Therefore, one way to increase the attraction of young generation visitors to the Multatuli Museum is to combine Augmented Reality technology with objects in the Museum so that the enthusiasm of the younger generation to visit the museum becomes greater.

RESULTS AND DISCUSSION The results of this study include: A.

Data collection
As an illustration of the system currently running at the Multatuli Museum, it can be seen in Figure 3 below: Use case (UC) diagrams, explain visually the context of the interaction between the actor and the system. Each use case states a specification of the behavior (functionality) of the system being described that is needed by the actor to fulfill his goals. [15]The following is the use case diagram of the application: Figure 4. Use case diagram In this use case there is only one actor, namely the user who is a passive actor who can only use this application. the user scans using an AR camera to visual objects in the form of image targets that are available in each room. Next the system will process according to the target image that has been planted on the android system, when the system recognizes the appropriate target image, the display on android will display 3D animation objects complete with audio related information about the room the user is going to, including Image Image 1 to 7.

Application Installation
Before operating an application that uses Augmented Reality techniques on the Android platform, it is necessary to make sure we already have an Image (marker) which will be used as an object to be scanned by the AR camera. To operate this application, it can be done directly by opening the application that is already installed on the Android platform.
To install the Augmented Reality Museum Multatuli application on Android devices, you can do 2 ways: a). Building directly through the Unity Application provided that the Android device must be in developer mode and enable usb debugging mode, so that the device can be read by Unity b). Direct application installation that the author has uploaded via: https://drive.google.com/file/d/10AIckMWlmmtSo qI62O1VorI_HB3rO0Vi/view?usp=sharing. Or you can directly scan the QR Code below: When 3D animation appears on the display, then the information in each room in the museum in the form of audio will be played. Information in the form of audio can be heard clearly, but it is recommended to use a headset so as not to disturb other visitors.
Following are the results of images for each room from rooms 1 to 7 in each museum with different audio information for each room. Image Target is a visual object that is used by AR as a marker when 3D objects are displayed on the display. The image targets used in this study can be seen in the following figure: The name Multatuli is taken from the pen name of Eduard Douwes Dekker when writing the novel Max Havelaar. This museum has a land area of 1834 square meters and a building area of approximately 314 square meters. With 7 exhibition rooms consisting of the Welcome room, the room for the early arrival of Europeans to the archipelago, the Forced Cultivation Room, the Multatuli room, the Banten room, the Lebak room, and the temporary Museum room.
