Abstract

Indonesia has been gifted with a wide range of diverse cultures from Sabang to Merauke, making Indonesia one of the biggest country with multi ethnic groups, races and cultures. Meanwhile, a lack of information that can be accessed by the students causing a big issue that needs to be addressed. The information of Indonesian traditional clothing is very limited, which has been represented as a characteristic of tribe and culture in each region and also used in the traditional ceremony. Therefore, this study aims to develop an Android-based educational game of traditional Indonesian clothing. The method used in this study was Research and Development approach. The results of this study showed that developing an educational game "Introduction to Traditional Clothing in Indonesia" on the Android platform,that provided information to users about any traditional musical instruments in Indonesia, helped students to recognize the particular culture through its traditional clothing as it could give an insight to them. From the results of testing carried out with the black box method, it could be concluded that this application enabled to function well and provide the beneficial information to user about the traditional clothing.

Abstract

The importance of preserving Sumatra batik motifs as a cultural heritage is facing major challenges in the digital era. The problem of this research lies in the difficulties in digitalizing and commercializing batik motifs effectively and maintaining authenticity and cultural value. This article aims to explore the use of the Turtle Graphic as a tool for digitalizing and down-streaming Sumatra batik motifs. Turtle graphics were initially crafted as an instructive instrument for educational settings, paving the way for teachers to demonstrate drawing concepts. On a different note, it also serves convenience to coders needing graphic output - offering them a solution without necessitating more complicated or external libraries in their projects. The research method involves applying graphical programming (using Turtle graphics) to produce digital representations of batik motifs. The technical aspects of digitization implemented in the Turtle Graphic are (1) data identification, which is done by creating a table to select motifs that are currently rare; (2) motifs that have been identified are revitalized through making simple sketches; (3) sketches are made in digital Turtle Graphics to make it easier for MSMEs to document and implement into prototype batik models. One example of the batik motif used in this research is the Daun Sirih Melayu batik motif. This batik motif often uses images of betel leaves that are intertwined and sticking out.  The Daun Sirih Melayu batik motif was chosen as a representative example because the philosophical meaning of the betel leaf batik motif symbolizes a form of respect. Betel leaves are also important in tradition, especially at proposals, weddings, traditional title awards, and other events. The research results show that Turtle Graphics can simplify digitalization. These contribute to the preservation and socialization of Sumatra batik and support the sustainability and popularization of batik in an increasingly digital global context.  Academics can also use this research as a basis for further research, while for MSMEs, it is a good opportunity to implement it in batik centers in the archipelago, especially on Sumatra island.

Abstract

Using the Turtle Graphic algorithm to digitize and develop Sumatra batik motifs is an innovative step in preserving local wisdom. This algorithm, which was originally used in graphics programming to educate children about computer concepts, is now being utilized to design and reproduce intricate and detailed batik motifs. The problem is that most existing batik motifs have not been digitally stored. Therefore, the purpose of the research here is to digitize Sumatra batik motifs using the Turtle Graphics algorithm. Turtle graphics utilizes command-based programming principles to draw geometric shapes. As an icon for North Sumatra Province, the basic motif of the existing water tower batik is the focus of this pattern accuracy. It is documented using a Python program that uses the turtle graphics algorithm, and a new Sumatran batik motif design is created from this basic motif. The benefits of research results with this approach are that designers can digitally modify and reproduce traditional batik motifs. This algorithm allows the drawing of patterns with high accuracy, making creating consistent and precise motifs easier. This digitization process also helps document and preserve batik motifs. The use of this technology not only speeds up the design process but also provides wider access to the younger generation and the international community to appreciate and learn about Sumatra batik. By integrating modern technology and local wisdom, the digitization of rare batik motifs has the potential to strengthen cultural identity and increase the economic value of traditional batik products. The specific steps in the motif digitization or pattern-making process are as follows: determine the motif to be digitized, select the starting point of the moving turtle, determine the turtle's direction of motion in relation to the curve to be formed, execute the program, and if the turtle curve does not move in the desired direction, change the program and execute again until the turtle motion curve matches the desired curve. This process is repeated multiple times.

Abstract

Sumatran batik has motifs that have deep meanings adopted from everyday life, and many are already rarely produced.The problem in this study is how the process of revitalizing Sumatran batik will be downstream into the creative industry. The purpose of this study is to create a digital revitalization model for rare Sumatran batik motifs, with a focus on their integration into the local creative industry, which can increase cultural awareness and increase market potential in the creative industry. The method used is descriptive qualitative with a visual language approach. The sample in this study is a digital batik with a sample of the Tarok-tarok Boraspati produced by MSMEs. Results show that digitizing batik motifs not only maintains visual authenticity but also enables scalable and market-relevant innovation, contributing to cultural preservation and creative economic growth. The main result is a structured batik composition that maintains the identity of the main motif while enabling wider commercial applications. This approach offers a replicable model for other cultural regions that aim to combine heritage with innovation and increase global cultural visibility through the creative industry.
