Sasak Ethnomathematics: Unveiling Mathematical Wisdom in Lombok Culture explores the fascinating relationship between mathematics and the cultural heritage of the Sasak people of Lombok Island, West Nusa Tenggara, Indonesia. This book reveals how mathematical ideas are embedded in traditional knowledge, everyday activities, cultural practices, and community life. By connecting mathematics with local wisdom, it challenges the perception that mathematics exists only in formulas, symbols, and classroom instruction. Through ten comprehensive chapters, this book examines diverse mathematical concepts within Sasak culture, including traditional counting systems, geometric principles in bale architecture and mosques, measurement practices in agriculture, patterns and symmetry in traditional weaving, and mathematical reasoning in customary exchanges. It also investigates the mathematical dimensions of merariq, begibung, peresean, and calendrical traditions associated with Wetu Telu, demonstrating how mathematical thinking is connected to social relationships, cultural values, spatial reasoning, and temporal understanding. Beyond documenting cultural practices, this book presents ethnomathematics as an interdisciplinary approach that bridges mathematics, anthropology, education, and cultural studies. It emphasizes that local communities possess valuable forms of mathematical knowledge developed through generations of practical experience, observation, creativity, and interaction with their environments. These perspectives provide opportunities to reconsider mathematics as a living form of human knowledge shaped by cultural and historical contexts. This book is particularly valuable for mathematics teachers, university lecturers, students, researchers, and cultural practitioners interested in developing culturally responsive education. It offers insights for designing contextual learning materials, ethnomathematics-based activities, project-based learning experiences, and interdisciplinary research. By incorporating Sasak cultural heritage into mathematics education, educators can help learners understand abstract mathematical concepts through meaningful real-world.
