Abstract

An experiment to analyze the effect of plant growth regulator α-Naphtaleneacetic Acid (NAA) on somatic embryogenesis moon orchid Ph amabilis (L.) Bl. was 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 0,1 mg/L, 1 mg/L, 2 mg/L, 3 mg/L, and 4 mg/L NAA. The explants were cultured in medium NP without NAA were used as control. The formation of embryogenic callus was observed every day, while the formation of somatic embryo was observed every week for 6 week using a dissecting microscope. The result showed that somatic embryogenesis Ph amabilis (L.) Bl were influenced by plant growth regulator NAA. Explants were cultured in medium NP without NAA didn’t embryo formed, while explantswere cultured in medium NP added with 2 mg/L, 3 mg/L, and 4 mg/L NAA embryo formed at embryogenic callus appear. These somatic embryos formed as an indirect via callus phase.© 2007 Jurusan Biologi FMIPA UNS SurakartaKey words: moon orchid, α-Naphtaleneacetic Acid (NAA), somatic embryogenesis

Abstract

Some actinomycetes which were isolated from Bukit Bangkirai fire forest in East Kalimantan have been identified. Those isoates were also characterized for its cellulolitic and phosphate solubilizing ability. Identification was based on Miyadoh (1997) and Holt (1994) methods. Actinomycetes could be identified by microscopic observation on spores, chain spore, hypha, aerial hypha and its pigmentation. The cellulolitic ability was observed by clear zone ratio in CMC medium and phosphate solubilizing activity by same approach in Pikovskaya medium. From 91 Bukit Bangkirai’s actinomycetes isolates which had been deposited in LIPI Microbial Collection (LIPIMC) were identified as 7 genera (Streptomyces, Nocardia, Microbiospora, Micromonospora, Microtetraspora, Streptosporangium and Actinoplanes). 57,14 %phosphate solubilizing actinomycetes and 38,46 % cellulolitic actinomycetes were detected with clear zone ratio average of 1,48 and 1,59 respectively.© 2007 Jurusan Biologi FMIPA UNS SurakartaKey words: Actinomycetes, spore, chain spore, aereal hypha, phosphate solubilizing, cellulase

Abstract

Neem (Azadirachta indica) is a multifunction plant. Its leaves and seeds can be used as a traditional medicine. One of the benefits of neem seeds is that they can serve as antibacteria. It happens because neem seeds contain certain substances which can impede the growth of Salmonella thyposa and Staphylococcus aureus bacteria. The aims of this research were to find out the efectiveness of soaking neem seed powder in hampering the growth of Salmonella thyposa and Staphylococcus aureus bacteria and to find out the active chemistry compound in soaking neem seed powder based on the result of Tin Layer Cromatografi (TLC). It was an experimental research. Paper disc method was used to find out the impeding ability of soaking neem seed powder toward both kinds of bacteria. The effective concentration is shown by the existence of the biggest barrier area in that concentration. Based on the result of this research, it was known that the barrier’s diameter (didn’t include the paper disc’s diameter ) at Salmonella thyposa is as follow : soaking neem seed powder with 0% concentration (control) = 0 mm, 10.5% = 2.33 mm, 11.5% = 3.0 mm, 12.5% = 18.67 mm, 13.5% = 5.33 mm, 14.5% = 5.0 mm, and15.5% = 4.0 mm. While the barrier’s diameter at Staphylococcus aureus is as follow : soaking neem seed powder with 0% concentration (control) = 0 mm, 10.5% = 2.0 mm, 11.5% = 2.83 mm, 12.5% = 19.67 mm, 13.5% = 4.0 mm, 14.5% = 3.0 mm, 15.5% = 5 mm. Based on qualitative test result with TLC, it was found that the active chemistry compound in soaking neem seed powder are saponin and flavonoid. Based on this result, it can be concluded that soaking neem seed powder can impede the growth of Salmonella thyposa and Staphylococcus aureus.© 2007 Jurusan Biologi FMIPA UNS SurakartaKey words: Neem (Azadirachta indica), Barrier, Salmonella thyposa and Staphylococcus aureus, Paper disc, TLC

Abstract

Several indicators used to evaluate revegetation programs are survival, plant growth, root growth, cover, litter production, natural recolonisation, habitat improvement, microbes, insects, and birds. To study the prediction of the potency of Collembola as bioindicator of revegetated tin-mined lands, population densities on revegetated tin-mined lands under Acacia mangium stands at 0, 3, 7, 9, 12, and 13- years old were measured using pitfall trap method. It was recorded four Collembola species i.e. one belongs to family Isotomidae, two to family Entomobryidae, and one to family Sminthuridae. Population density of Collembola spp. in unrevegetated tin-mined land (0-year old) was significantly different to those in revegetated tin-mined lands. Although population density was higher in the older revegetated tinminedlands with the highest density recorded in 13-year old site (4816 ind. m-2), densities among revegetated tin-mined lands were notsignificantly different. The different population density appears related to organic material, litter either from revegetated plant, or from plant invaders during succession, and soil humidity. This study confirms the prediction of the potency of Collembola population density as bioindicator of revegetated tin-mined lands under Acacia mangium stands.© 2007 Jurusan Biologi FMIPA UNS SurakartaKey words: , Collembola, bioindicator, revegetation, tin tailing, Bangka

Abstract

Plant adaptation to serpentine soils is a system ideal for studies in evolutionary ecology. Serpentine soils are characterized by low calcium to magnesium ratios with Ca at significantly lower concentrations relative to surrounding areas. Although some variation occurs between sites which identified three collective traits: poor plant productivity, high rates of endemism and vegetation type distinct from those of neighboring areas. The several morphological feature characteristic of serpentine-tolerant species is possess xeromorphic foliage, including reduced leaf size and sclerophylls, the stature is significantly reduced relative to counterparts on non serpentine soil and root systems of species growing on and off serpentine sites are often more developed on serpentine soils than on neighboring soils. Serpentine soils are ubiquitous, but patchily distributed and thus promote geographic isolation. Adaptation to edaphic conditions may also begetreproductive isolation. Adaptive mutation might be influenced frequently from related species inhabiting surrounding areas. For the future studies involving serpentine systems merge the fields of ecology, evolution, physiology, and genetics required for serpentine adaptation.© 2007 Jurusan Biologi FMIPA UNS SurakartaKey words: adaptive mutation, endemics, isolation, magnesium, serpentine

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
