Abstract

A methanol soluble fraction extracted from Kayu Manik leaves (Trema orientalis) from Seluma, Bengkulu, exhibited an antiradical activity 69.73% (scavenging activity of the stable 1,1-diphenyl-2-picryl hydrazyl (DPPH) free radical) that was almost similar to that of 1 mM ascorbic acid. On the other hand, the iron chelating activity was 40.74%. We believe that it would be useful to take the results as an alternative for processing industries and can be observed as a good source of new agent for iron chelator.

Abstract

A bird is a wildlife which could be found almost in any vegetated environment. The existence of a bird in one area is very important because it could affect the presence and distribution of plant species. This study aims to determine species composition, attendance of birds, evennes, species diversity, and the dominance of birds in Saembawalati Swamp Forest. The study was conducted from April to June 2013. Data collection was carried out using line transect method. After conducting the research in Saembawalati swamp forest, it was found 34 species of birds from 15 families, swamp forest habitat tree vegetation zones have indeks values species diversity (H) = 2.75 and evenness (E) = 0.11 and swamp forest habitat zones has turf vegetation index values species diversity (H)=3.00 and evennes (E) = 0.10. There were four species of birds that are always found in the swamp forest of Saembawalati; Egretta garzetta, Gallinula chloropus, Phaenicophaeus calyorhynchus, and Amaurornis phoenicurus. Hence, Saembawalati swamp forest was dominated by four species of birds; Bubulcus ibis, Egretta garzetta, Dicrurus hottentottus, Phaenicophaeus calyorhynchus.

Abstract

Indonesia is a tropical that has vast forest regions. The existence of the forest region is national asset must be managed continuously and developed to the better way so that they can be sustainable utilized. Herbal plant is a kind of forest product non wood which useful for ecology, social-cultural, or economic that must be managed as long as the utilization rationally to nowadays generation needs and the fature. The objective of the research was to find out the difersity of herbal plants located in preserved forest utilised by Tindoli people at Tindoli village of South East Pamona Sub District Poso Regency. The vegetation analysis method in the field was multi plots method which purposively done. The vegetation specimen taking was done by emloying 20 plots specimen located in spread. The size of the observation plots was 20m x 20m made as 20 plots that the whole wide of observation plots was 0.8 ha. The research result done in preserved forest at Tindoli Village of South East Pamona Sub District Poso Regency found that there were 25 kinds of herbal plants including 21 familes. For each of tree vegetation level, it was obtained the kind of diversity index 1.87, pople vegetation level 1.96, stake vegetation level 1.76, seedling vegetation level and plants 2.43. based on the index calculation of herbal plants diversity at the preserved forest in Tindoli Village from herbal plants of seedling level and underground plants, stake level, pople level, they were generally categorized low.
