ABOUT US
The Hariara Institute is dedicated to environmental conservation and education in the Lake Toba area. Its name, “Hariara,” is derived from the Toba Batak language, referring to a large and sacred tree. In Latin, this tree is known as Ficus drupacea and holds deep philosophical significance for the Batak people, symbolizing a prosperous life. The Hariara tree represents the harmony between nature and humanity, with each part of the tree carrying its own meaning: the leaves symbolize protection from danger, the stem signifies good fortune and blessings, and the roots embody unity between people and the natural world.
