Development of Endomycorrhizal Fungi Inoculum Production by Using Mycorrhizal Helper Bacteria as a tool for Increasing Inoculum Quality (2010)
by: S. W. Budi, N. L. May

Eight isolates bacteria were isolated from surface sterilized endomikoriza spores of Gigaspora sp and six isolates bacteria isolated from Glomus sp. Enzymatic activity test showed that there were seven isolates that produce cellulase and protease activity that is GG1, GG3, GG6, GG7, GL2, GL4 and GL6. The tests to  the antagonists against fungal pathogens and stimulation of endomycorrhizae hyphal development of Gigaspora sp  in vitro and their application in the production of AMF inoculum showed that there we...

Effect of Microwave Treatment to the Enzyme Susceptibilities in Saccharification of Sago Pith (2010)
by: T. C. Sunarti, A. Meryandini, N.Richana

Composition of dried sago pith was mainly starch and fiber components.   Direct conversion of sago pith into glucose will reserve the water  and save the energy for starch extraction and starch drying.  This research developed the saccharification process of sago starch and fiber directly from sago pith by using microwave heating treatment and enzymatic process, and produced fermentable sugars.  Conversion process included the pretreatment by microwave heating in water; starch, cellulose and hemicellulose hydrolysis int...

Callus Induction Of Cottonii Seaweed (Kappaphycus alvarezii (Doty) Doty) Colleted From Natuna Islands, Riau Islands Province (2010)
by: E. Sulistiani, D.T. Soelistyowati, Alimuddin, S. A. Yani

The objective of this study was to obtain the optimal medium for callus induction from thallus explants of K. alvarezii. Before cultured, Cottonii seaweeds collected from the Natuna Islands (Riau Islands Province) were acclimatized in greenhouse and in semisterile culture in the laboratory. Sterilized explants were cultured on PES and Conwy media solidified with 0.8% Bacto agar. In each of these media were added two combinations of plant growth regulators i.e. BAP+IAA and BAP+NAA. The
concentrations of BAP used were 0, 0.5, 1 mg/l, the con...

Mitochondrial DNA Analysis of Genetic Diversity in Sumatran Elephant (Elephas maximus sumatranus) Populations (2010)
by: S. Sulandari, M.S.A.Zein

A research on Mitochondrial DNA analysis of genetic diversity in Sumatran elephant (Elephas maximus sumatranus) was conducted in this study.  A 630 bp segment of mitochondrial DNA was amplified on 105 samples of Sumatran elephant from 5 locations in Sumatera (Bentayan, Sugihan, Bukit Salero Lahat, Seblat, Way Kambas) using a set of primers: MDL3 (5’-CCCACAAT-TAATGGGCCC-GGAGCG-3’) and MDL5 (5’-TTACATGAATTGGCAGCCA-ACCAG-3’). The objectives of this study is to generate mitochondrial DNA D-loop sequences for al...

Development of Molecular Marker for Sengon (Paraserianthes falcataria) Resistant to Stem Borer (2010)
by: U. J. Siregar, A. S. Wulandari

Establishment of monoculture Sengon (Paraserianthes falcataria) plantation in wide area has posed a high risk of attack from pests and diseases. The main pest, which was reported destroying Sengon plantation is stem borer (Xystrocera festiva). Although most Sengon trees are susceptible to the pest and disease, some resistance trees were reportedly present and survived among seriously damaged plant populations. In order to investigate whether such resistant individuals have different genetic background from susceptible trees, a...
