Android-Based Augmented Reality Application for Batak Musical Instrument Recognition

Abstract

Indonesia’s vast archipelago has given rise to a rich diversity of ethnic groups and customs. This diversity is reflected in the country’s many languages and cultural expressions—one of the most distinctive being music. Traditional music is typically performed with instruments that have been used for generations, although in some regions modern instruments are also employed to accompany traditional pieces. In North Sumatra, particularly within Batak Toba culture, several traditional instruments are commonly used to accompany dances and ceremonial events. These instruments are often considered indispensable for customary ceremonies. However, as time passes, public awareness and appreciation of traditional musical instruments have declined. Augmented Reality (AR) is a medium that blends images, video, audio, and text into the real-world environment, allowing users to feel as though they are directly experiencing what they see. The development of AR technology on smartphones can greatly help students learn about Batak Toba musical instruments. This study presents the design of an Android-based AR application for recognizing Batak Toba traditional instruments. The application features three-dimensional visuals that correspond to the actual instruments, concise textual descriptions, audio explanations, and samples of each instrument’s sound. Overall, the “Android-Based Augmented Reality Application for Batak Toba Musical Instrument Recognition” was implemented effectively according to the proposed concept and design. The application was developed using the C# programming language, Unity 3D for application development, Blender for creating 3D objects, and Adobe Photoshop CS3 for logo design. This AR application offers a new and engaging way for students in Indonesia—especially in North Sumatra—to access concise information about Batak musical instruments.
