Ekspedisi 80 Gunung Arjuno 3339 Mdpl Menumbuhkan Kehijauan di Jalur Sumber Brantas Cangar

The 2023 forest fire on Mount Arjuno burned more than 3,315 hectares of land, threatening biodiversity and damaging the balance of the local ecosystem, including the loss of large trees and a decline in soil quality. In response to these conditions, the 80 Gunung Arjuno 3339 Mdpl Expedition was initiated as a form of community service aimed at restoring the ecosystem through tree planting along the Sumber Brantas–Cangar hiking trail. This activity involved collaboration between the Forestry Service, the Naval Academy, the Indonesian National Armed Forces, the community, students, and volunteers. The implementation method included preliminary studies, procurement of local tree seedlings such as mountain pine and eucalyptus, structured planting along the hiking trail from post 2 to post 3, and post-planting monitoring by Tahura Raden Suryo. A total of ±300 participants planted around 600 trees in this expedition. In addition to planting, participants also carried out mountain clean-up activities. The results of the activities show that tree planting can reduce the risk of erosion and improve soil structure after fires, as well as encourage community involvement in sustainable environmental conservation. This activity proves the importance of cross-sector synergy for effective and sustainable environmental restoration.
