Abstract

Ethnomathematics is important in recent decades, specifically in the production of gamelan instruments. Therefore, this research aimed to examine the intricate relationship between mathematics and cultural craftsmanship in Sundanese gamelan instruments made at Gong Factory in Bogor, West Java. Ethnographic methods were used to observe and describe the practices of gamelan craftsmen and the data collection process comprised carefully selected artists. These individuals actively acquire data by reviewing relevant material, observing, analyzing, and interviewing. Miles and Huberman's framework for data analysis included data reduction, presentation, inference, and verification. The procedures understood the delicate relationship between mathematics and culture in the investigated setting. The results showed that Gong Factory in Bogor preserved and promoted a unique musical heritage. Furthermore, the instruments were known for exceptional sound quality, serving as cultural relics and didactic tools, as well as teaching visitors about the manufacturing process. The factory preserved culture through the manufacture of gamelan instruments including gong, bonang, and saron. In this context, the craftsmanship used mathematical principles, specifically precise proportions and ratios. The instruments' visual and auditory qualities depended on geometry. The results significantly impacted mathematics education by enhancing cross-cultural connections, improving proportional reasoning and mathematical comprehension, and recognizing the wider relevance of principles. Culture, mathematics, and education were connected, showing that conserving Indonesian musical tradition benefited local and global populations.

Abstract

This research is an ethnographic study using two AI tools (ChatGPT and Gemini AI) to analyze comparatively the different patterns between Javanese and Sundanese batik. The data was obtained from two AI-generated outputs of two prompts focusing on geometric patterns and transformations. The study used a triangulation process by matching and contrasting AI-generated outcomes with previous literature. The findings reveal that: 1) Javanese batik motifs contain more geometric designs, in the other hand, Sundanese batik tends to use more fluid and organic patterns, and 2) the majority of Javanese batik combines both reflection and rotation, whereas Sundanese batik uses translation and reflection. Math properties from both batik designs are inspired by different cultures. Batik patterns from Java represent values such as balance, organization, and class whereas Sundanese batik expresses Sundanese beliefs about respect for nature. It highlights that traditional arts should be integrated into mathematics teaching to better understand and appreciate their role in various cultures.
