The antioxidant properties of methanolic extract of T. copelandii Elmer bark have been evaluated by using free radical (DPPH) scavenging assay, reduction power and Ã-caroten bleaching assay. Ascorbic acid (vitamin C) and âbutylated hydroxytolueneâ (BHT) were used as positive control or antioxidant standard. Total phenolic content was estimated by using Folin-Ciocalteu reagent and expressed in gallic acid (Gallic Acid Equivalent), while total flavonoid content was estimated by using aluminium chloride reagent and expressed in routine (Routine Equivalent). The result shows antiradical activity of extract on concentration 40 Âµg/ml was 89.96%, lower than vitamin C (95.61%) but higher than BHT ((52.25%). The reducing power of extract on concentration 50 Âµg/ml has absorbance value 0.644 lower than vitamin C (0.769), but higher than BHT (0.475). During 2 hours incubation, extract on concentration 50 Âµg/ml inhibited Ã-caroten bleaching 69.46% higher than control negative (35.81%), but lower than BHT (85.99%). Estimation of total phenolic and total flavonoid content showed that extract contained 350.40 Âµg (GAE)/g extract and 277.50 Âµg (RE)/g extract respectively. The antioxidant properties may be attributed to the presence of phenolic and flavonoid compounds present in the extract.

Pangumbahan coastal area is one of many important nesting sites of the green turtle (Chelonia mydas Linnaeus) in Indonesia. This area is mainly comprises of disturb coastal old secondary forest. Some sites along the seashore were converted into fishpond, dry land agricultural and other was destroyed for other uses or as an open unproductive areas. However this area has a still plays an important role especially for the conservation of green turtle habitat and also for the ecosystem stabilization of the coastal area in general. Floristic research was conducted on September 2009 to investigate the existing vegetation structure and composition along the seashore using transects method.The Ã¢â¬Åpoint center quarters methodÃ¢â¬Â was used to calculate the importance value of the vegetation on every turtle nesting sites. The important natural species vegetation communities in the area were comprises of herbs, shrubs and trees species. Ipoemoea pes-caprae (L.) R. Br and Spinifex littoreus (N. L. Burman) Merrill as a first layer coastal line plant community that play as an important herbs species which creeping grown on the white sands coastal surface. The second layer comprises herbs, small trees and shrubs such as Pandanus tectorius Parkinson ex Zucc, Crinum asiaticum L. and Callotropis gigantea R.Br. The second layer species plays as a vegetation community which covering and protecting the green turtle nest site from the direct sunshine, running of big wave and heavy rain water. Terminalia catappa L., Calophyllum inophyllum L., Barringtonia asiatica (L.) Kurz. and Hibiscus tiliaceus L. as a big crown tree community grown covering on the most behind as a back layer of coastal line which play as shading trees of the second layer species community, especially to stabilized humidity and temperature of the sand and the environment. The vegetation structure and composition of the old secondary coastal forest of Pangumbahan was described to understand the detail role and function of the vegetation species in this area.

Indonesia has great potentila in terms of community forest reaching more than 42 million ha. This potential, however, is still unwellmanaged so that is couldnt be a main source of farmersincome. In fact, according to argo ecology system; community forest can be cultivated by introducing promising intercrops in order to deliver more benefical effect. To overcome this problem, a reseach aiming to obtain potential models for community forest and spice crops intercropping pattern based on agro ecological zone was conducted from Â August to December 2000. The reseach was carried out on 1.000 ha of partnership-based community forest (Paraserianthes falcataria) in Lengkong and Tegalbuled Sub district,sukabumi Regency, West Java province. the objectives of the research were achieved through survey method in gathering primary and secondary data. The data were analyzed by using Expert system Program (version 3.2.2.) and Framework of Land Evaluation. the results showed that the community forest explored was devided into 6 agro ecological zones with 5 recommended-landuses. Those are forestry (Zone I), palntation (Zone IIlax and IIbx), agroforstry (zone IIIax and IIIbx), and upland cultivation (Zone IVax2). According to microlimate condition under P.Falacataria trees, bushy pepper (Piper nigrum) is the most promising intercorps. Meanwhile, framework of land evaluation revealed that Zingiber officinale, Amomum cardamomum, and other Zingiberaceae species were marginally suiltable accompanied by heavy texture as the main constraint. In short, the potential models were (1) P. falactaria + A. cardamomum; (2) P.falactaria + P.nigrum. (3)Â P.falactaria +Â Z.officianale and (4)Â P.falactaria + Zingiberaceae (Curcuma xanthorizza, C.domestica, and Kaemferia galanga). Model (1),(3) and (4) would be more suitable on zone IIIax,IIIbx, and IVax2, whereas model (2) should be on zone IIIax nad IVax2.

Research on gall (including field and laboratory observations and field collecting) have been conducted in the Mounts Gede Pangrano (MGPNP) and Halimun Salak National Parks (MHSNP). This research focused on gall shapes, host plant species, and parts of the host plants infected by galls. The result showed that there were 169 gall numbers in MGNP and 127 numbers in MHSNP have been collected. Distribution of plant species infected by the galls were rather same in the both conservation areas. In MHSNP seven families mostly infected by galls: Araceae, 4 species of 5 gall numbers collection in the family (=4/5), Elaeocarpaceae (5/5), Euphorbiaceae (7/9), Lauraceae (8/11), Moraceae (6/7), Melastomataceae (4/4) and Rubiaceae (9/12). In MGPNP the composition is only fairly different: Araliaceae (4/6),Euphorbiaceae (8/13), Lauraceae (9/12), Melastomataceae (5/6), Moraceae (13/22), Myrtaceae (9/11) and Rubiaceae (6/13). At least 23 gall shapes were found in both locations. The most common shape of galls found in MGNP was irregular, while in MHSNP was globular.Galls were mostly (90%) collected from leaf including peduncles and leaf venations. The other parts included twigs, branches, stems, flowers,and fruits. The most common insect found investing galls (i.e. insect gallers) was the midges (54.4%) followed by mites (18.5%), psyllids (11.1%), thrips (6.3%), coccids (1.9%), and aleurodes (1.9%).
