STRUKTUR VEGETASI DAN SIMPANAN KARBON HUTAN RAKYAT DESA SAMBAK, MAGELANG, JAWA TENGAH

The private forest is forests that are developed on private-owned land rather than in forest areas. The diversity of plants making up private forests depends on the interests of each owner. One of the sustainable private forest practices is in Sambak Village, Kajoran District, Magelang Regency. It can be seen from the high level of population participation in planting forest plants on their lands. However, there is a lack of information about the vegetation structure was planted in the Sambak Village private forest. The calculation of carbon stock in private forests is carried out to reveal the role of private forests in carbon sequestration. Data collection techniques using the transect method with an observation plot measuring 20x20 m with a distance between plots of 50 m. The method of calculating carbon stock is using a non-destructive method by estimating carbon stock based on the diameter and height of the tree. The results showed that the composition of the plants making up the private forest vegetation consisted of 24 species from 16 families. These results are consistent with the calculation of the highest importance value index achieved by Falcataria falcata (L.) Greuter & R.Rankin (70.67), Swietenia macrophylla King (52.18), Cocos nucifera L. (37.53), and Artocarpus heterophyllus Lam. (25.21). However, the calculation of carbon stock shows that the highest potential carbon storage is owned by Cocos nucifera L. which is 1034,07 ton C/ha. The total carbon stock of Sambak Village private forests is 3499,89 ton C/ha.
