The increasing number of the world's population, especially in Indonesia, has led to an increase in the need for clothing and shelter. In order to fulfill these needs, communities carry out massive exploitation of forest resources. This exploitation action is in the form of changing or converting forest land into food land or residential land for the community. This activity results is reduced carbon absorption land and an increase in greenhouse gases in the atmosphere or well known as climate change. So, it is necessary to protect and manage the environment, one of which is through environmental communication in local cultural traditions. In this case, communication is believed to provide a platform that is able to facilitate the process of exchanging information, knowledge, and wisdom. The good synergy between the government, environmentalists, as well as local cultural traditions that have long been developed and preserved in the community is expected to be an action to mitigate global climate change. This study was used qualitative research methods and data collection was done through interviews, observations, and documentation. The results showed that the local cultural tradition known as sidekah turun ton is a tradition carried out by the Karang Bayan indigenous community once every 8 years in order to maintain the harmonization of nature and humans. The tradition of preserving the forest is one way to communicate the importance of protecting the environment for the survival of the community in the future.
