Abstract : Provide a clear and concise summary of the study, including: purpose, methods, key findings, and main conclusions. Piodalan is one of the sacred ceremonies in Balinese Hinduism that serves as an implementation of Dewa Yadnya, namely a sacred offering dedicated to Ida Sang Hyang Widhi Wasa and His manifestations. This study aims to analyze the philosophical meaning of the Piodalan ceremony, describe its implementation in the daily life of Hindus, identify the Hindu literary sources underlying its practice, and examine the challenges and solutions related to its preservation in the modern era. This study employs a qualitative descriptive method using a library research approach. Data were collected through the review of books, scientific articles, Hindu scriptures, and other relevant literature. The findings indicate that Piodalan is not merely a religious ritual but also embodies spiritual, social, cultural, and ecological values reflected in the concept of Tri Hita Karana, which emphasizes harmonious relationships between humans and God (parhyangan), among fellow humans (pawongan), and with the natural environment (palemahan). The implementation of Piodalan involves a series of ceremonial stages supported by various offerings (banten) as symbols of devotion and gratitude. Furthermore, the ceremony is grounded in Hindu teachings contained in Lontar Sundari Gama, Catur Marga, and Sruti and Smrti literature. However, modernization and globalization have posed challenges, including declining spiritual understanding among younger generations, reduced community participation in ngayah activities, and environmental concerns regarding ceremonial materials. Therefore, strengthening religious education, promoting community participation, and implementing environmentally sustainable practices are essential strategies to preserve the meaning and continuity of the Piodalan ceremony in contemporary Hindu society.
