Abstract

Polyphosphate accumulating bacteria play  important key role on biological phosphorous removal. Activated sludge originated from wastewater treatment plant for drinking water production acclimated with anaerobic-aerobic phase in sequential batch reactor continuously succeed to establish microbial community that are able to adsorb glucose and acetate under anaerobic condition.  Acinetobacter calcoaceticus S1 was an isolated bacterium from community performing organic substrate absorption. S1 is able to adsorb glucose and acetate under anaerobic condition. During substrate absorption an increase of orthophosphate in bulk solution indicating phosphate released out of cell. Reduction of glycogen and polyhydroxybutirate (PHB) took place under anaerobic phase. S1 is a community member of anaerobic-aerobic system for removal of phosphorous in influent wastewater.

Abstract

Gelatik Jawa (Padda oryzivora L) merupakan salah satu spesies burung yang terancam punah dan perlu dikonservasi. Salah satu penyebab kepunahan adalah ketidakmampuan spesies tersebut untuk beradaptasi dengan perubahan alam sekitarnya yang dapat ditunjukkan pada perubahan  ciri biokimiawi individu seperti indeks hematologis. Penelitian ini bertujuan untuk mempelajari apakah ada perbedaan indeks hematologis pada empat subpopulasi gelatik Jawa   di Jawa Barat, Jawa Timur, Bali Utara dan Bali Selatan.  Hasil penelitian menunjukkan bahwa indeks hematologis  darah  gelatik Jawa dari empat subpopulasi  tersebut dengan bobot badan  antara 21-30 g, memiliki  nilai rerata eritrosit 5,00±0,60 x 106/mm3; leukosit 2,35±0,86 x 103/mm3; PCV 61,32±11,62%; limfosit 58,25±17,32%; heterofil 35,93±15,72%; monosit 3,05±2,98%; dan basofil 0,05±0,21%.  Ratio heterofil terhadap limfosit (H/L) burung tidak meningkat seiring dengan meningkatnya suhu lingkungan. Diduga hal tersebut disebabkan gelatik Jawa sudah beradaptasi dalam waktu yang relatif lama terhadap lingkungan lokal.

Abstract

Sandalwood  (Santalum album L.)  is known as a fancy plant. Since they have  high economic value, it often over exploited.  As a consequence, the population  dramatically decreased  in their habitats.  Some efforts  have been  done  to conserve  this plant  in order to prevent their extinction, i.e.  seedling multiplication.  As a  hemiparasitic plant,  sandalwoods  need other  plants for a host which grow  around.  Therefore, determining of the the primary host is a necessary aspect in multiplication  of  sandalwood seedling.  This study  used  three  species  plants  to serve sandalwood seedling   as  primary host  in pot cultures consist of local leucaena (Leucaena glauca), vilosa (Acacia villosa)   and calliandra  (Calliandra  calothyrsus).   The results  of this study indicated   that A. vilosa  is better for a primary  host  than  L. glauca and  C. calothyrsus as well. Number of  root connection  between  sandalwood seedlings   and their hosts  have a close correlationship   to  the leaf  number  and the  sandalwood seedling   dry weight, whereas no significant correlationshifp to their height.

Abstract

The presence of some genetic markers related to malaria as hemoglobinopathies, enzymophaties and ovalocytosis in populations of Lesser Sunda Islands  are presumed to be quite high, since this archipelago is mostly malaria endemic. To elucidate the problem, a series of observations had been done among  579 blood samples which were collected from five different populations (Balinese, Sasak, Sumbawanese, Sumbanese,  and Alorese) representing inhibitant of Lesser Sunda Islands. In this paper we present the distribution of Southeast Asia Ovalocytosis (SAO) which was detected  by microscopic examination of the red blood cell morphology. Among these, 38 subjects were suspected as SAO whereas the incidence ranges from 2.2% in Balinese to 15.7% in Alorese.  It was predicted that the high incidence of SAO in Alorese might be associated with malaria selection to compensate the absence of hemoglobinophaties in this population.

Abstract

This study aimed to obtain binary vectors carrying  cryIB-cryIAa hybrid gene suitable for Agrobacterium-mediated transformation of two Indonesian rice cultivars, Rajalele (Javanica) and Cisadane (Indica).  Introduction of hybrid Bt toxin, encoded by cryIB-cryIAa hybrid gene with different binding receptor in the insect gut driven by maize ubiquitin promoter, was intended to reduce the possibility of the appearance of stem borer resistant to Bt toxin. A HindIII fragment containing the ubi cryIB-cryIAa hybrid gene was excised from pBKS ubi cryIB-cryIAa and cloned into the HindIII site of binary vector pCAMBIA 1301, 1303, or 1304.  Restriction analysis of recombinant plasmids confirmed the insertion of the gene and demonstrated that the gene inserted in two orientations. The recombinant plasmids were transformed into electrocompetent Agrobacterium tumefaciens EHA105 by electroporation.  Embryogenic calli of Rajalele and Cisadane were co-cultivated with A. tumefaciens EHA 105 harbouring binary vector pCAMBIA 1301, 1303, or 1304 containing ubi cryIB-cryIAa. GUS histochemical assay revealed that high transformation efficiency (75-100%) on both cultivars were obtained from embryogenic calli transformed with pCAMBIA 1303 or 1304.

Abstract

The aims of this study  were to identify the growth curve of  B. amyloliquefaciens on  corn-starch and non corn starch addition media,  number of cells  and production of a-amylase on variety initial pH during the stationary phase. The growth curve of B. amyloliquefaciens was made using the water optical density on both  medium which has inoculated by microbes. The experimental design for the a-amylase production was factorial completely randomized design (6 x 3 x 3). There were two factors included in this study i.e. initial  pH of the media ( 5,  5.5,  6,  6.5,  7 and 7.5) and incubation times (16, 18 and 20 hours). The results showed that B. amyloliquefaciens growth curve on medium with corn starch was slower than on medium without corn starch. Production of  a-amylase and number of cells were having similar patterns in all treatments, i.e. increased until optimum pH and incubation time were reached. The number of cells and a-amylase production were optimal at pH 6.5 for 18 hours incubation whereas the number of cells  (about 2.8542 x 108 cells/ml)  and a-amylase production (1.4467 units/ml) were optimal at pH 6.5 for 18 hours  incubation.

Abstract

National Park is a nature conservation area has a wild  ecosystem and managed by zone system. Baluran National Park (BNP) is one of conservation area in Indonesia covered 25,000 hectare consists of 420 hectare of Bekol’s savanna and 150 hectare of Bama’s savanna. From  4.345 grass-feeding mammal  in BNP, it has estimated that their total weight about  777,000 kg  and  the total feeding need  about 77,700 kg  per day. On the other hand, the biomass of the grasslands only 86.125 kg/ha/day, and both Savannas could only produce biomass about 40,478.75 kg  per day which was  not enough to support the daily animal feeding. Decreasing of the biomass in BNP was assumed as a result of habitat destruction by animal step printings.  The purpose of  this study is to know the effect of animal step printing to the biomass production.  Samples was taking from April to December 1999 using quadrates method which was applied following the animal step printing and the control (non-stepped area). The plant samples were kept in plastic pocket and then identified  in the laboratory. The total  number of quadrates could be detected in this study were 150.  From this study it was concluded that  Grassland which was stepped by banteng, water buffalo and deer  decreased the number of plant species  until 38.88%, 27.27% and 18.18% respectively.

Abstract

Purwodadi Botanical Garden has more than one hundred collection of cultivated bananas. The major problem in keeping their existency is  the occuring of  Fusarium wilt disease  which was commonly controlled by pesticide or eradication to terminate the infectious cycles. Trichoderma and Gliocladium were frequently used as antagonist fungus in controlling the Fusarium wilt disease in kenaf, tomato or  the other plants. So,  this study aims was to know the  potency of Trichoderma and Gliocladium on Fusarium growth inhibition. The experimental design was done by Randomized Complete Design Factorial using three factors i.e. antagonist fungus, Fusarium and growth distance. The level of retardation was measured by the growth distance of Fusarium  that interacted to antagonist fungus and data analysis were conducted  by Analysis of Variance (ANOVA). The results showed that Trichoderma has higher inhibition than Gliocladium and the highest inhibition occurred at 1 cm  distance of inoculum which was performed on Fusarium 4 (77.78%). There was not any significant differencies between Fusarium 1 with Trichoderma (73.55%) and Fusarium 2 with Gliocladium (73.33%). At 2 cm distance, the highest inhibition occurred in Fusarium 3 by Trichoderma (72.71%), which  was not significantly different with Fusarium 1, 2 and 4. While at 3 cm distance, the highest inhibition on Fusarium 4 by Trichoderma  was 51.11% and not significantly different from Fusarium 1, 2 and 3.
