Ajeg Bali: AI-Based Digitalization of Jejahitan Culture to Preserve Balinese Tradition

Balinese jejahitan is a crucial cultural heritage laden with religious values in every Hindu traditional ceremony in Bali. However, along with the rapid current of modernization and globalization, the interest and understanding of the younger generation towards this mejejahitan tradition are increasingly declining. The complex geometric shapes of jejahitan and their visual similarities to one another often make their preservation feel difficult for today's youth.

The Existence of Balinese Jejahitan Today: A Threat or an Opportunity for Digitalization?

A survey of the youth in Denpasar City shows that 42.5% have low knowledge, 38.9% have sufficient knowledge, and only 14.2% have a good understanding of the types of Balinese jejahitan. This indicates a crisis in cultural regeneration. Cultural digitalization becomes an important solution.

This is where Ajeg Bali, which stands for “Aplikasi Jejahitan ring Bali”, comes to transform a threat into a golden opportunity. This application is a tangible manifestation of the digital transformation of Balinese culture. Remarkably, Ajeg Bali is not just an ordinary application. Behind the scenes, this application is powered by a state-of-the-art Artificial Intelligence model based on Deep Learning and Computer Vision that has been specifically trained using thousands of original datasets of jejahitan images. The result? This application is capable of achieving an extraordinary final accuracy rate of 98.21% in classifying 18 different classes of Balinese jejahitan.

Ajeg Bali presents three main focuses:

1. Smart Recognition: Users can recognize 18 types of jejahitan instantly simply by taking a picture or uploading a photo, thanks to the support of highly advanced Computer Vision (AI) technology with a model accuracy rate reaching 98.21%.
2. Jejahitan Encyclopedia: Users are invited not only to know the names, but also to delve into the philosophical values and specific functions of each jejahitan in Balinese traditional ceremonies through comprehensive descriptions.
3. Practical Guide (Tutorial): Users are facilitated to directly learn to arrange or make the jejahitan through the integration of interactive and easy-to-follow step-by-step YouTube video tutorial links.

Interface Display of the Splash Screen, Home Page, and Balinese Jejahitan Articles

Ajeg Bali is designed by prioritizing user convenience (user-friendly) so that anyone, anytime, can learn about jejahitan without confusion. As soon as the application is opened, users will be greeted with a fresh Splash Screen displaying the application's identity. Next, users will be directed to an interactive Home page. Here, there is a catalog or encyclopedia of various kinds of Balinese jejahitan. Users can directly explore articles on Balinese jejahitan containing descriptions of names, meanings, functions, as well as video tutorials on how to make them to broaden their basic knowledge before starting to take pictures of jejahitan.

Interface Display of Image Capture using Camera/Gallery Upload

This is the main advantage of Ajeg Bali. Do you find jejahitan at the temple or at home but do not know its name? There is no need to bother asking around. Simply open the camera feature within the application, then capture (photograph) the jejahitan, or upload an existing photo from the smartphone gallery. In a matter of milliseconds, the AI model will immediately process the image.

Interface Display of the Classification Results of the Ajeg Bali Application

After processing, the application will display a super comprehensive results page. Users will not only know the name of the jejahitan along with its prediction accuracy rate, but the application will also display an in-depth explanation regarding the philosophical meaning and function of the jejahitan in the upakara. Moreover, Ajeg Bali is also integrated directly with YouTube video tutorials! So, users can immediately watch step-by-step guides on how to make the newly scanned jejahitan.

Ajeg Bali is a tangible example of how advanced technology can be a connecting bridge between the past and the future. When the mejejahitan tradition begins to be displaced by an instant lifestyle, digitalization efforts like this become an innovation in supporting sustainable education. Learning to recognize and make jejahitan is no longer boring or considered outdated, but rather becomes a fun interactive experience right in the palm of your hand.
