Abstract

An ecological research on some endangered medicinal plants in Ranu Pani, Senduro and Pronojiwo Resort, Bromo Tengger Semeru National Park, East Java was conducted on July 2006. Nine study areas were chosen inside the forest of national park and one site at the enclave area (non-forest area), covering a wide range of plant association, abundances, forest and habitat types, and altitudes. A systematic parallel line sampling method using quadrat technique was employed and total area sampled were 1 ha. The total of 13 medicinal plant species were found in quadrats and there were three species i.e. Euchresta horsfieldii (Lesch.) Benn., Cinnamomum sintocBl., and Alyxia reinwardtii Bl. known as endangered species which seemed to have a tendency for cluster distribution. Instead of being discovered inside the conservation area, an endangered species, Pimpinella pruatjan Molkenb., was found at an agriculture land in the adjacent area. The Shannon-Weaver diversity index was 1.10 with Evenness value of 0.99. Based on contingency table constructed from the sampling result, we found no single association between the endangered medicinal plant species. Habitat, conservation status andpotential threats of the four endangered species are also briefly described.© 2007 Jurusan Biologi FMIPA UNS SurakartaKey words: endangered medicinal plant, ecology, diversity, conservation

Abstract

Dengue virus infection is the main cause of morbidity and mortality in the tropical and sub-tropical countries of the world. Clinically it may manifest as asymtomastic, undifferentiated fever,dengue fever,dengue haemorrhagic fever and dengue shock syndrome cases.. The mechanism underlying the disease with severe complication is not clear yet,however it has been previosus reported that primary andsecondary infections of dengue virus play an important role in the patogenesis of this diseases. Early diagnosis of dengue virus infection has a great contribution for appropriate management of the disease, especialy for the prognosis of the patient. Laboratory investigations for such cases will be methods on serological investigation as well as virus isolation and identification.of dengue virus infection could be madeby detection of specific virus ,viral antigen,genomic sequence and or detection of antibodies. These methods are sensitive and precise for detecting dengue virus infection,but there need special equipment,costly and detection of IgM and IgG often positive or negative false the dengue virus in the blood stream There for, this study was performed in order to develop a method to detect dengue virus antigen on the monocytes using Streptavidin biotin technique. The result of Streptavidin biotin study demonstrated that 32 sera from patient suspectedwith DHF 78,1% were positive DHF,and 21,9% were negative DHF. These results are consistent with the result from WHO criteria as standard .The Chi Square analysis showed that the presentage of sensitivity and specificity of Streptavidin biotin methode were 88% and 87,7% respectively. In conclusions ,immunocytochemistry method using streptavidin biotin technique could be used as a method to detect antigen dengue virus on monocytes in the serum patient suspected with DHF. This technique has high sensitivity and specivicity andconsistent with the clinical WHO criteria for DHF,© 2007 Jurusan Biologi FMIPA UNS SurakartaKey words: Dengue Haemorrhagic ,Monocyte , Steptavidin biotin

Abstract

Burung Island is one of many islands in the Karimunjawa Islands that belong to Karimunjawa National Park conservation area. The purpose of this study is to discover the structure of bird community especially the species diversity and its habitat structure in Burung Island. The study was conducted on June 2006, November 2006, and June 2007 in Burung Island. The study was conducted by using point count method. The radius of each point is approximately 20 meters, while the time interval of observation on each count is 10 minutes. Thedistance between each point in this study is 100 m. The habitat observation was conducted by using habitat profile of tree cover vertical structure which was done descriptively by looking at the function of cover level to the present of bird or the relation between level and the present of bird in that location. The study’s result indicated that there are 15 recorded bird species from 10 family in the location, in whichfive species (five family) among them are protected by the government, which are Sterna sumatrana, Egretta sacra, Nectarinia jugularis, Caloenas nicobarica, and Falco moluccensis, and two of them were included in CITES (Convention on International trade in Endangered Species) appendices 1 and 2, which are Caloenas nicobarica and Falco moluccensis. The highest values of species diversity index (H’) and evenness index (E’) can be seen from the observation’s result of June 2007, which are 1.8837 and 0.836. The habitat of Burung Island is very suitable for Caloenas nicobarica, Egretta sacra, Sterna sumatrana, and Sterna bergii as a place for breeding. The use of vegetation level by bird in Burung Island is dominated by the use of low and base levels.© 2007 Jurusan Biologi FMIPA UNS SurakartaKey words: Bird, community, Burung Island, Karimunjawa National Park

Abstract

Research to analyse protein synthesis during somatic embryogenesis of moon orchid Phalaenopsis amabilis (L.) Bl has been carried out. One year old of plantlets were used as explants sources. Basal leaf of these explants were cultured in medium New Phalaenopsis (NP) added with 2mg/L NAA during 1 day (P1), 2 days (P2), 4 days (P3), 6 days (P4), 8 days (P5). The explants were cultured in medium NP without NAA were used as control, during 1 day (K1), 2 days (K2), 4 days (K3), 6 days (K4), 8 days (K5). Analysis of the protein synthesiswas observed by electrophoresis using SDS-PAGE method according to Maniatis et al. (1982). The measuring of protein bands used the densitometer. To detect the specific protein which possible function in controlling embryogenesis by comparing profiles of leaf protein which cultured at NP media added NAA and without NAA. The analyses of protein profile were done at the culture of day 1, 2, 4, 6 and 8 after inoculating. Result of the research indicated that a protein of 14 kDa was detected in the explants were cultured in medium NP added NAA only, and it was not detected in explants were cultured in medium NP without NAA. This protein probably embryonic protein has a function to control embryogenic callus initiation. A protein of 16 kDa was detected in the explants were cultured in medium NP added NAA and without NAA. This protein is possibly siklin has a function to regulation of cells proliferation during embryogenesis.© 2007 Jurusan Biologi FMIPA UNS SurakartaKey words: Phalaenopsis amabilis (L.)

Abstract

To examine the phosphatase alkaline activity of VA mycorrhizal fungi in the rizhosphere and in root, teak seedlings inoculated spores of VA mycorrhizal fungi were grown in sterilized soils. Teak seedlings were fertilized with NPK fertilizer consisting three levels, i.e. 0; 0.0625; 0.125 g per seedling. Phosphatase alkaline in rizhosphere was measured in terms of pNP on soil dry weight basis, meanwhile alkaline phosphatase activity in roots were quantified in using method developed by Tisserant. The results showed that alkaline phosphatase activity increased on inoculated seedlings compare to with uninoculated. NPK fertilization of 0.0625 g per seedling and inoculation on teak seedlings showed alkaline phosphatase activity in range 90-201 EU, and in roots indicated in range 14-72%. Gigaspora sp inoculation on teak seedlings was showing the highest of alkaline phosphatase activity. Increasing phosphatase alkaline activity relevant to hyphae growth, and increasing of root infection decreased alkaline phosphatase activity. Arbuscular mycorrhizal inoculation increased seedling dry weight.© 2007 Jurusan Biologi FMIPA UNS SurakartaKey words: teak, alkaline phosphatase activity, Gigaspora sp, Glomus sp

Abstract

Meru Betiri National Park is located in southern part of East Java Province. Inventory of orchid species was conducted to study orchid diversity in Meru Betiri National Park, especially in Bandealit coastal area. Observation of orchid within host trees was also done to study the preference host trees for orchid growth. It was recorded that there were 25 orchid species belonging to 20 genera. Twenty species of which are epiphyte and 5 species are terrestrial. The most common epiphyte orchids were Pomatocalpa latifolia, Pomatocalpa spicata, Rhynchostylis retusa, Micropera pallida and Grosourdya appendiculata. While terrestrial orchid was only found in a small number, with common terrestrial orchids were Corymborkis veratrifolia and Goodyera rubicunda. The most preference host trees for epiphyte orchid were Tectona grandis (Teak), Clausena indica, Lagerstroemia speciosa, Mangifera indica (Mango), but there is no specific relationshipbetween host trees and epiphyte orchid© 2007 Jurusan Biologi FMIPA UNS SurakartaKey words: orchid, host trees, Meru Betiri National Park

Abstract

The objective of this research was to determine the silk characteristics of Jedung silkworm reared on Senggugu food plant. Cocoon characteristics examined was the weight of cocoon and the value of Shell Ratio (SR). Meanwhile, the characteristics of fiber conclude the tensile strength, the elongation and the moisture absorption. The results showed that the range of cocoon weight was between 5.849 + 0.378 g. If it is compared to other cocoon reared on other food plants, the cocoons from Jedung silkworm were less weight. This wasprobably because of the characteristics of Senggugu leaf that was thinner and less water content which will produced cocoon with less weight. The lower weight of cocoon could affect to the value of measured SR. The value of SR was 9.828 + 1.475 %. The good range of SR value is between 19-20 %. The tensile strength was 14,444 + 5.270 g per denier. The good range of tensile strength is between 2.6 to 4.8 g per denier. The elongation was 2.184 + 2.168 %. This study showed the elongation was lower compared to other characteristics ofgood fiber with value more than 18 %. The moisture absorption varies between 20.214 + 0.618 %. It will cause fabric made from this material were considered cooler to wear, so that relatively good from the side of convenience.In general, characteristics of the fiber were relatively good. Therefore, it needs higher effort to increase weight of cocoon and the elongation of fiber.© 2007 Jurusan Biologi FMIPA UNS SurakartaKey words: characteristics of fiber, Jedung silkworm, Senggugu food plant
