Abstract

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.

Abstract

Osteochilus is a genus of fish with large lips,everted, sucker-like, covered with more or less folds of plicae bearing numberous unicellulair keratinous projections or uncuil. The structure of thr lips Osteochilus is divided into three from i.e. ectomorph, mesomorph and endomorph, based on the length and shape of plicae on the lateral portion of the upper lip, the distribution of uncuil and taste buds on the plicae , also from the size and shape of uncuil. Osteochilus partlilineatus is a small fish which has a nice colour patteern, so it is potential as an ornamental fish. it has an ectomorph lips, which the structure of plicae,uncuil and taste buds. The from of the taste buds redemble the rose flower which are very different with the structures of that 7 other Osteochilus that were examined by Roberts using scaning Electro Microscope (SEM).

Abstract

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  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) P.falactaria + Z.officianale and (4) 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.

Abstract

Steem root disease caused by Fusarium oxysporum Schl. f. sp. Vanillae (Tucker) Gordon represent one internal issues of vanilla development (Vanilla planifolia Andrews). To obtain resistance clone to the disease, it can exploit resource of wild vanilla (V. albida B. L Syn) through crosses. Hybrids which were interspecific crossed generally were sterile. To overcome sterility problem of the hybrids, chromosome doubling was made by colchicine application. Explant used globular structure of proembryo from F1 seed result from a cross between wild vanilla of Ciamis as female parents and cultivated vanilla clone of Ciamis as male parent. Concentration level colchicine used were 0.00%, 0.05%, 0.10%, 0.20% and 0.25% with period of treatment of 3 and 6 days. After colchicine treatment embryo cultures were subcultured into new mwdium that was basal media Murashige-Skoog enriched with 2.5 mg/l BAP. Result of the experiment showed that colchicine treatment,globular structure were F1 embryo tending to inhibit early regeneration. The cultures showed variabilities from treatment of colchicin 0.20% during of 6 day and 0.25% for 3 days. Phenotypic performance of the chromosome doubled hybrids showing great variation in color and vigor of the culture. Tetraploid plant(2n=4x=64) was obtained from the colchicine treatment of 0.25% for 6 days. Chromosome addtion was followed by improvement of cell dimensions and organ magnification.
