Implementation of Ethnomathematics in Jala Jelita Culinary Innovation: A Study of Community Empowerment Based on Local Wisdom in Buntu Bedimbar Village

Abstract

Ethnomathematics is a mathematics learning approach that integrates local culture with formal mathematical concepts. This community service program aims to provide training on the application of ethnomathematical concepts in Jala Jelita food to the people of Buntu Bedimbar Village, Tanjung Morawa District, Deli Serdang Regency. Jala Jelita is an innovation of Malay food mesh bread that contains various mathematical concepts in the manufacturing process. The implementation method includes initial surveys, program socialization, workshops on the practice of making Jala Jelita, identification of mathematical concepts, and evaluation of training results. The activity was carried out by involving 10 participants consisting of PKK women. The results of the activity showed that participants were able to identify various mathematical concepts in making Jala Jelita, including shape geometry (circle, spiral), measurement concepts (measurements, proportions), number patterns in the frying process, and economic calculations in determining selling prices. This training succeeded in increasing public understanding of the relationship between local culture and mathematics, as well as providing economic added value for MSME actors through education-based marketing innovations. The positive impacts achieved include increasing community mathematical literacy, preserving local culinary culture, and developing ethnomathematics-based creative economy potential.
