Coconut leaves that are still yellow in Javanese called Janur Kuning are decorations that are a sign of family party events such as weddings or other parties. Janur Kuning is usually installed as a sign of the entrance to the party.
Janur Kuning is made from young coconut leaves which are said to symbolize hope for the family who is holding a party. Hope of happiness of course.
For the Javanese people, it has been a hereditary tradition since the time of their ancestors that every wedding ceremony is always marked by the installation of yellow coconut leaves.
