Rantau Kermas Village received the National Kalpataru award for the "Environmental Savior" category. Rantau Kermas Village received an Indigenous Forest Decree in December 2016. At that time, it was directly ratified by President Joko Widodo. Long before obtaining the Indigenous Forest Decree, the people of Rantau Kermas had for generations had the initiative to protect and preserve the forest with the Serampas indigenous spatial system in Rantau Kermas Village, namely the existence of 'land of ulu aek' which is a protected area for water sources, Arai namely land that has a steep slope, Ajum Arah land which is intended to be used as agricultural land and settlements. This land designation system is regulated by the Depati who is the customary leader.
The election of Rantau Kermas Village as the recipient of the Kalpataru award cannot be separated from the good management that has been carried out by the community in protecting the forest. The commitment to protect the forest by the people of Rantau Kermas Village can be seen in the customary sanctions given to those who violate the rules, such as a fine of 20 bushels of rice, 1 goat, and Rp. 500.000 in cash.
These customary rules are set and obeyed by all communities. The existence of indigenous forests is very important for the community, especially to prevent the danger of ecological disasters. Located in an altitude area with a steep hilly topography with many tributaries with a fairly heavy flow. With this condition, protecting the forest is very important to protect the forest area.
From protecting this forest, the people of Rantau Kermas get many benefits. Since 2014 this indigenous forest has been managed by a tree caretaker. This program is an initiative of KKI Warsi to involve the public in managing forests. The way the public sends donations for foster trees is worth Rp. 200.000 per year/tree. So far, approximately 815 tree caretakers have been collected in the Indigenous Forest of Rantau Kermas Village. From the care of this tree, the community uses it to improve public facilities. such as rehabilitation of houses, beduk of the village mosque, repair of football fields, and provision of scholarships for underprivileged children and the elderly.
The 'foster tree' program is a form of public involvement to support communities that are already protecting their forests.
