Abstract

The plant Akway (Drimys beccariana.Gibbs) is endemic to Papua and is frequently used traditionally by the Arfak tribe as a medicinal plant. We extract the plant by maceration with ethanol. The antibacterial test is done by Agar diffusion method. As microba test we used Escheresia coli and Bacillus subtilis. Result obtained from fitochemistry skrinning of the leaf and bark contained alkaloid, flavonoid, steroid, tannin, glikosida, saponin, triterpenoid, steroid and fenolik. Concentration of active substances from the leaf are flavonoid (0,3680%) and tanin (10.33 %); while from the bark flavonoid 18.35% and tanin (27.65%). Antibacterial test showed that the plant could be used as an antibaterial substances. The test showed a moderate up to a strong blocking against Escherecia coli (a gram negative bacteri) and Bacillus subtilis (a gram positive bacteri). Thus it could be concluded that the Akway plant contain a substance with a bacteriostatic nature that could block the activity of the bacteri.

Abstract

Sponges are one of the components that compose coral reef which have a potential bioactive substance that has not been utilized. Sponges are generally able to survive in marine waters were nutrients are poor because of associations with other organisms, especially bacteria. This study aimed to isolate and characterize bacteria (endosymbiont and ectosimbion) that produce antimicrobial compounds, and analyze genetic diversity based on Amplified Ribosomal DNA Restriction Analysis (ARDRA). The results of isolation obtained 138 bacterial isolates, which are 70 endofit isolates and 68 surfaces isolates respectively. The results obtained, based on antimicrobial test, was 32 bacterial isolates (45.71%) of the total bacterial isolates that have endofit antimicrobial activity, whereas on the surface bacteria, 20 bacterial isolates (29.41%) of the total surface of the bacterial isolates also have antimicrobial activity. Genetic diversity was carried out on 30 isolates that has the best antimicrobial activity. Amplyfication of 16S rRNA gene is done using specific primers, 63f and 1387r. The profile of 16S rRNA gene band shows a high diversity, which is generated after cutting with three restriction enzymes i.e. RsaI, HaeIII and HinfI. The three restriction enzymes have different cuts and properties. Construction of phylogenetic trees based on analysis of Amplified Ribosomal DNA restriction, grouped 30 isolates from the sponge Jaspis sp. which have a microbial activity on seven filotipe. This grouping is based on the similarities cuts of sites of each isolate after restriction by three different restriction enzymes.

Abstract

Preparation and bio-ethanol analysis of sago (M. sago) starch from Papua have been carried out. The preparation of bioethanol was conducted by hydrolysis, fermentation, distillation and purification. The length of fermentation applied is 3, 4, 5, 6, 7 and 8 days. Bioethanol then was analyzed qualitatively and quantitatively. Qualitative analyses were boiling point and molecular weight determination. Quantitative analyses were determination of the volume of bioethanol content and the composition of bioethanol of every length of fermentation. Based on the qualitative analyses, the samples obtained was ethanol with boiling point of 79 oC and molecular weight of 46 gram/mol. Whereas, based on the quantitative analyses, the more the length of fermentation, the more volume of ethanol obtained and the composition of ethanol increased, with the optimum of the fermentation length was 8 days and the volume ethanol obtained was 123.5 mL, in addition the composition of ethanol at fermentation length of 8 days was 100%.

Abstract

Studi morfometrik telah dilakukan dengan mengukur 32 karakter dari 176 spesimen Dobsonia dari Papua. Spesimen-spesimen Dobsonia diwakili oleh enam OTU, yaitu G, B, R, E, SP1, dan SP2. Analisis univariat menghitung seluruh spesimen dewasa yang terdiri dari 171 karakter badan dan sayap dan 176 karakter tengkorak dan gigi pada enam OTU tersebut. Selanjutnya digunakan uji-t dan PCA untuk menghitung G, B, dan R, sedangkan tiga OTU lain (E, SP1 dan SP2) tidak dihitung tetapi ikut diproyeksikan ke dalam scatter plot. Hasil uji-t (p<0.05) menunjukkan ada seksual dimorfisme pada D. minor dan D. beauforti. Pemisahan D. magna, D. minor, dan D. beauforti nyata pada karakter badan, sayap, dan gigi berdasarkan PCA. D. emersa terpisah dari spesies lainnya pada karakter badan dan tengkorak. Hasil scatter plot pada SP1 dan SP2 mengelompok dengan D. beauforti pada semua karakter (badan, sayap, tengkorak, dan gigi). Sebanyak 32 karakter yang diukur didapatkan karakter taksonomi yaitu WT, HB, dan TV untuk karakter badan; FA, TIB, dan DIG1P untuk karakter sayap; ONL, POW, PL, dan MH untuk karakter tengkorak; I2M2, M2M2, WM1, dan LM1 untuk karakter gigi. D. minor yang telah ditemukan di Pulau Waigeo tahun 2007 merupakan catatan baru penyebaran spesies ini, sebelumnya hanya tercatat di daratan utama Papua dan Pulau Yapen.

Abstract

Ectoparasites are species of parasites that live on the outer surface of the body of an animal. They grow and are very dependent on the life of the host. The acarina complex includes predaceous mites of infinite variation, mites associated with plants and other animals and using a variety of organic substrates as food. The result from the identification showed that acarina parasite on white snake comes from the order Parasitiformes. The acarina encountered in snake’s skin inhabit the dorsal scales in lanes or take advantage of the gaps between scales from the posterior head to the scales near the cloaca.

Abstract

Effect of four types of diluentss and four concentration of DMSO (5%, 10%, 15% and 20%) against the motility of African catfish sperm were evaluated after storage at freezing temperatures. The steps in preparation the 16 treatments combination of the diluents are preparation of diluents, mixing diluents with DMSO, packing of semen into 0.3-ml straw, equilibration of semen at 4 °C for 30 minutes, freezing of semen in nitrogen vapor liquid at a height of 6.5 cm for 10 minutes, and subsequently storage of semen in liquid nitrogen (-196 0C) for further analysis of post-thawing motility (PTM). The result showed that the highest level of motility of spermatozoa was in treatment P1D15 (45.7 ± 4.3%) and the lowest was in treatment P2D20 (14.5 ± 13.2%). The best diluent in this observation was diluents containing NaCl, KCl, CaCl2 and NaHCO3. The best concentration was DMSO 15%. While the best interaction between the concentration of DMSO diluents is P1D15 treatments containing NaCl, KCl, CaCl 2 and NaHCO3 with a combination of 15% DMSO concentration. The conclusion of the research is that diluents containing NaCl, KCl, CaCl2 and NaHCO3 with a combination of 15% DMSO concentration can be used in cryopreservation of African catfish semen.
