Indonesian people have their own way to protect their environment. In protecting the environment, the Javanese people carry out the norms, values, or rules that have been passed down through generations.Local wisdom is the values or behavior of the local people in interacting wisely with the environment in which they live. Local wisdom is built as guidelines, controls, rules, and signs to behave between humans or with nature. It contains the noble values of the community to protect and manage the environment in a sustainable manner. The noble values are believed to be true by the community and become a reference in daily actions and behavior. This illustrates that Indonesia is a nation that cares about nature and upholds ancestral traditions. The following are some examples of local wisdom that exist in Indonesian society:

Usually, for one or two years. When it is taking place, people are prohibited from taking certain marine animals of high economic value such as sea cucumbers, lola (a type of sea shell), batulaga (a type of sea snail), and lobster. The closing begins with a traditional ritual using the symbol of a coconut. Sasi Enggama is hereditary by people who live in the coastal areas of Kaimana.
