This study examines the role of Mandar women in crafting Layar Karoroq (Sails from gebang leaves) during the sea cucumber trade era, beginning in the 17 century-a multi-ethnic maritime network linking the Indonesian archipelago to northern Australia. Mandar women's skill in processing gebang leaves into sails was essential for long-distance voyages, fostering ethnic collaboration and advancing maritime commerce centered in Makassar.
Using an ethnographic approach, this research combines historical analysis, interviews, and observation to examine sail-making techniques. Findings show that cross-ethnic collaboration forged a shared seafaring identity, enriched by friendship with Aboriginal communities. Through cultural revitalization and sustainability theories, this study highlights preservation efforts through youth education, ensuring the relevance of this maritime heritage.
