This study aims to explain the basis of environmental accountability implemented in the Yadnya ceremony in Malakosa Village, Parigi Moutong, Indonesia where majority of the population is Balinese Hindu. The research method employed is qualitative descriptive. This study reveals that the concept of environmental accontability in the Yadnya ceremony in Malakosa Village is based on the Tri Hita Karana values. Tri Hita Karana value is a form of self-reminder and self-control to maintain one’s relationship with God, human, and environment. This concept emphasizes the balance and harmony values which build the concept of environmental accountability in the Yadnya ceremony. In this culture, humans are commanded to care for the surrounding environment. Tri Hita Karana (THK) is one of the local wisdoms of the Balinese people, the heritage of their ancestors (ancestors) based on Hinduitis. The philosophical aspects of THK are sourced in 4 (four) philosophical thoughts, namely: Theocentric, Cosmocentric, Anthropocentric, and Logocentric aspects. Theocentrism is a theory of philosophical thought that everything comes from God. God is the creator of the universe and its contents. Anthropocentric is a theory of philosophical thought that humans are the center point, because complete humans have tri pramana (sabda, bayu, and idep) which are advantages over other living things, namely having the ability to think. Cosmocentric theory of philosophical thought that nature is the center of everything, while Logocentric is a theory of philosophical thought that the term or statement/expression is the source. In this case, Logocentric animates the term or word harmony in THK which is used as an interpretation of the Balinese philosophy of life which is always in process, changing, innovative, and constructive. In this concept, humans become the central point as well as the subject in the implementation of THK in everyday life, especially at the yadnya ceremony in the village of Malakosa.
