Environmental Anthropology Study: The Relationship of the Sentani People with the Lake

This article describes the cultural traditions of the Sentani people, an ethnic group that supports water and lake culture, as implied in the phrase "ra phu, ra wally" (I have water, I have life). This phrase states that water, specifically Lake Sentani, is their life. The lake is crucial to their survival, so they practice cultural conservation to preserve it. However, the lake's ecosystem has been disrupted by environmentally unfriendly development. People no longer care for the lake's environment. This occurs because they do not understand the philosophical significance of Lake Sentani for the Sentani people. This research was conducted in Sentani using descriptive qualitative methods with observation and interview techniques.
