Jayapura – Lake Sentani in Papua is not only a beautiful panorama that welcomes the eyes from the air, but the heart of the life of the indigenous people who depend on the water, land, and the surrounding culture. For the people in Tanah Tabi, this lake is a living space that unites humans with nature and keeps traces of the long history of Papuan ancestors.
The stilt houses by the lake are witnesses of daily life that blends with the rhythm of nature. From the sago forest that is a source of staple food to the tradition of making bark paintings that have been passed down from generation to generation, every corner of Lake Sentani reflects the values of local wisdom and the harmonious relationship between humans and their environment.
Archaeological researchers note that the area around Lake Sentani keeps ancient cultural relics that describe the life of the Papuan prehistoric community. The discovery of artifacts and ancient settlement patterns is evidence that this lake has long been the center of civilization and inter-tribal interaction in the eastern region of the archipelago.
But in the midst of its charm, Sentani Lake is now facing a serious threat. Pollution due to household waste that flows without treatment, the transfer of sago land into residential and industrial areas, as well as nickel mine exploration plans in the surrounding mountains cause great concern. If not controlled immediately, this condition is feared to damage the balance of the ecosystem and erode the cultural values that have been living in the community.
Traditional figures and environmental observers call for the importance of joint efforts to preserve Lake Sentani. They emphasized that protecting the lake is not only protecting nature, but also maintaining the identity and long history of the Papuan people.
“Sentani Lake is a mirror of life and priceless ancestral heritage. If this lake is damaged, then part of the Papuan identity will also be lost,” said a local traditional figure.
Hopes continue to be voiced so that the government, indigenous people, and the young generation of Papua will unite to protect this lake. Through a cultural approach and local wisdom, conservation efforts can be a joint movement to ensure that Lake Sentani remains a source of life and inspiration for a sustainable Papuan future.
