Palms diversity, composition, and density in six selected sites of 15 rectangular plots of 100 x 20 m were successfully studied.The sites are in Kasepuhan Ciptagelar, which located in the Gunung Halimun Salak National Park in West Java.The sites are in the disturbed primary submontane forest at 800 to 1400 m altitude. Ethnobotanical observations made in some of the villages in Kasepuhan Ciptagelar proceeded through informal unending open interviews involving some traditional elders, prominent communities, and handicraftsmen. There is no species addition to the park from the Kasepuhan Cigelar. Three species of rattans(Calamus polysiachys, C. burcklanus, and Korthalsia laciniosa) are added to the park from Cibedug, Leuwijamang, Ciptarasa, and Cikidang. Young leaves of Daemonorops rubra are used for traditional Inner Baduy cloth. The use of C. javensis canes for bracelets and rings, and the infructescence of Plectocomia elongala for decoration are new findings.

Terminalia is the second largest genus of Combretaceae family, consists of 200 species distributed in the tropics and subtropics. Many species of Terminalia are well kown in traditional medicine Â in several countries of Africa and Asia. In this study, bark extracts of four species of Terminalia (T. catappa, T. citrina, T. bellirica and T. macadamii) were evaluated for their in-vitro anti-inflammatory and antioxidant activity. Determination of the anti-inflammatory activity was carried out using red blood cell membrane stabilization assay and the antioxidant activity was carried out using DPPH free radical scavenging and ferric reducing power assay. Estimation of total phenolic Â content was carried out using Folin-Ciocalteu reagent, while Â total flavonoid content using alumminium trichloride reagent. The results showed that extract of T. catappa has the most potent anti-inflammatory activity (IC50= 97,83Â±0,0100 ?g/mL) and the most powerful Â antioxidant activity of DPPH free radical scavenging (IC50= 21,8900 Â± 0,0264 ?g/mL) and ferric reducing power (IC50= 87,1533 Â± 0,04163 ?g/ mL). The weakest anti-inflammatory activity was T. citrina extract (IC50= 159,35Â±0,0200 ?g/mL), whereas T. bellirica extract demonstrated the weakest antioxidant activity of Â DPPH free radical scavenging (IC50= 44,4867 Â± 0,0153 ?g/mL) and ferric reducing Â power (IC50= 140,89Â±0,04 ?g/mL). The extract of T. citrina has the highest content of total phenolic (84,8167 Â± 0,53407 mg GAE/g) and flavonoid (23,1200 Â± 1,7149 mg RE/g) while the T. macadamii extract has the lowest content of total phenolic (24,3700 Â± 0,0173 mg GAE/g) and flavonoid (13,2667 Â± 0,3386 mg RE/g).

Some plant species growing in the contaminated areas, indicated high tolerance and potentially affective in accumulating pollutants. These plants can be utilized as hyper accumulators for cleaning up contaminated sites. This research aims to examine plants that grow under Hg contaminated media and to analyze their potency as hyper accumulators. Two pioneer plant species Enterolobium cyclocarpum (Willd.) Griseb and Centrosema pubescens Bent. that proven tolerant and dominant at contaminated sites of gold mine were examined in this research. The plants were grown in liquid media added with mercury (HgCl2) with different level of concentrations 0 ppm, 10 ppm and 20 ppm. Chelate Ammonium Thiosulphate [(NH4)2S2O3] was added with concentration levels of 0 ppm and 20 ppm. Plant performances, cellular responses, Hg accumulation in the plant were assessed. The results revealed that the growth of both plant species decreased with the increase of Hg contamination level. The presents of chelating agent improved adaptability of the plants, indicated by the increase of biomass production and Hg content in the plants, even at the highest level of Hg concentration (20 ppm). Cellular responses showed at 20 ppm Hg, indicated by the decrease of both the number and the size of epidermis and pith cells. Accumulation of Hg in the plants increased with the increased of Hg concentration in the media. Mercury accumulation in both plant species were more concentrated in the root system rather than the shoot.

Indonesias plant diversity potentially as natural dyes. A general process in dyeing with natural dyes needed mordanting workmanship on the material to be dyed/stamped. The process of mordanting is done by immersing the material into the metal salts, such as aluminum, iron,tin or chrome. Amid fears of negative impacts caused by dyes and synthetic mordant to health and the environment, people begin to look back the use of natural dyes. So far, the material used for mordanting is alum; though Loba tree (Symplocos fasciculata Zoll.) is one type of plant that can be useful as mordant but today not many people knows the role of this plant. This paper aims to determine the S. fasciculata role and its use as mordant for natural dye textiles. The method used was interviews with parties concerned. The results of this research is aknowledge on S. fasciculata role as a mordant as local wisdom in traditional Balinese weaving. Plant parts that may be used are leaves and inner bark. Conservation efforts is eagerly continued by Eka Karya Bali Botanic Gardens-The Indonesian Institute of Science (LIPI). Currently two species (among 250 naturally grow) of Symplocos conserved at Eka Karya Bali Botanic Garden-LIPI.

The Study of soil arthropoda diversity in Upper Katingan River area was done in five different forest types i.e. 4 natural forest (With different vegetation) and one industrial tree plantation (HTI). The research site belongs to the PT Dwima Jaya Utama a consession timber in Central Kalimantan. Pitfall traps and soil litter samples were used to collect the arthropods and insect specimen. Twenty pitfall traps were set along 2 transect with 100 m length in each site and were operated forfour day. five soil-litter smaples of two litter were collected from each site. Soil-litter samples were examined in Berlese funnels for two weeks to sort the animals from debris. Identification was done based on the morphological appearce (morphospecies) and some taxon was determined up to order and/of family name. The results show that the most dominated taxon were collembola consit of 103 species from 13 families, and Coleoptera (33 species, 11 families). The most dominated taxon from Class Arachnid was Acarina (11 taxon) and Araneae (7 families). The Kilometer 33 (PUP) area has the highest species richness and abundance, whereas the Industrial Tree Plantation (HTI) has the lowest one of soil Arthropods. Based on the role of Arthropods on the forest floor, the most dominated group was decomposer and followed by predator and phytophagous. The unknown group mostly was consist of juveniles.
