Abstract

CITES (Konvensi PerdaganganInternasional Flora dan Fauna yang TerancamPunah) telah ditetapkan tahun 1973 diWashington. Indonesia telah meratifikasinyapada tahun 1978. Namun ternyata publikasimengenai pelaksanaan CITES di Indonesiayang lengkap belum ada. Sehingga terbitnyabuku ini: “CITES Implementation in Indonesia“ perlu kita syukuri. Buku ini cukup lengkapmembahas mengenai pelaksanaan konvensiperdagangan internasional jenis jenis Flora danFauna yang terancam punah di Indonesia.Sayangnya buku ini baru ditulis dalam bahasaInggeris.

Abstract

The objective of this research was to prove that galangale rhizome (Alpinia galanga L. Swartz) can be used to preserved “pindang” tuna fish (Euthynnus pelamis L.). The fish were cooked by galangale rhizome solution (the concentration were 0, 50, 100, 150, 200 mg/l b/v) for15 minutes. Then, the fish were stored in box, three fishes /box, and stored at room temperature for 6 days. Every day, The quality of fish were measured as colour, rubberness, taste, odor, total of bacteria and fungi. The result showed that there were decreased of the fish quality, spoilaged, and many fungi and bacteri growth after two days, and the level of spoilage of fish was influenced the increasing of galangale rhizome concentration. It concluded that the galangale rhizome can not use as “pindang” tuna fish preservative.

Abstract

The research of insecticide effect to the growth of genus Chlamydomonas had been done.  Research was experimental study with block random design to 9 concentrations of chlorpiriphos containing insecticide in Beneck and soil water media i.e. 0 (control), 0.05, 0.10, 0.15, 0.20, 0.25, 0.30, 0.35, and 0.40%.  Observations were done for 35 days.  Friedman test showed that there were some effects of media and insecticide concentrations on cell numbers of Chlamydomonas (cell/ml) in culture (p>0.05).  Dunnets test showed that mean of cell numbers of Chlamydomonas (cell/ml) differ (on p>0.05) and very differ (on p>0.01) on every concentrations in Beneck and soil water media.  Insecticide could reduced the cell size of Chlamydomonas, yet increased the number of cells on 0.05--0.30% concentrations in Beneck medium, and 0.05--0.20% concentrations in soil water medium.  On peak culture, insecticide with 0.10% concentration produced the highest cell numbers i.e. 21,179,167 cell/ml in Beneck medium, and 4,087,500 cell/ml in soil water medium.

Abstract

A total of 6 fungi isolates of growing at pH 9 and 2 isolates on pH 10 with amylolytic indexes 0f 0.07-1.42 have been isolated from cassava starch liquid waste. Two isolates having the highest amylolytic index were identified as Aspergillus sydowii K10 (1.42) and Aspergillus versicolor L30 (1.4). Both A. sydowii K10 and A. versicolor L30 were described as alcalotolerant for being able to grow with range pH 5-10. The optimal -amylases production of A. sydowii K10 and A. versicolor L30 was obtained after 4 and 3 days of incubation at 300C. The optimum of -amylase activity from A. sydowii K10 was at 400C and 700C, and pH 6; while those from A. versicolor L30 was at 500C and pH 6 respectively. Both A. sydowii K10 and A. versicolor L30 could produce glucoamylase. The optimum of glucoamylase activity from A. sydowii K10 was at 400C and pH 5, while those from A. versicolor L30 was at 500C and pH 5 respectively.

Abstract

A study on genetic variation of the high mountain fruit bat (Chironax melanocephalus) was conducted in Gunung Halimun National Park. DNA total from liver tissues were extracted and fragment of the 12SrRNA gene region of mitochondrial DNA were amplified by Polymerase Chain Reaction (PCR). Nucleotide sequence of the PCR products were determined by automated sequencer. Seven haplotype were found among 20 individuals from 6 localities, namely: South Halimun Mountain, Kendeng Mountain, Botol Mountain, Pasir Cangkuang Mountain, Kencana Mountain, and Buligir Putih Mountain. Haplotype diversity and nucleotide diversity were 0.76 and 0.0222. DNA distances values ranged from 0.0028 to 0.0202.

Abstract

Penelitian tentang penyerbukan dan sistem reproduksi Ranunculus japonicus telah dilakukan di kebun botani Universitas Osaka City, Katano, Osaka, Japan. Hasil penelitian menunjukkan bahwa putik R. japonicus lebih dahulu masak daripada benang sarinya (protogyny). Pada tumbuhan ini terjadi ketidakcocokan silang sendiri (self-incompatible). Tumbuhan ini tidak mengalami penyerbukan sendiri (selfing) dan juga tidak membentuk biji tanpa pembuahan (agamosper my), tetapi melakukan penyerbukan silang (out-crossing) dan membutuhkan perantara (pollinator) untuk pembentukan bijinya.
