Abstract

ABSTRAKFungsi redundan gen-gen ragi Saccharomyces cerevisiae dapat dipelajari melalui fenotip yang ditimbulkan ketika dua gen di rusak sekaligus. Konstruksi double disruptant protein fosfatase ptc2∆ msg5∆ dapat dilakukan dengan metodepersilangan-tetrad analisis. Single disruptant ptc2∆ dan msg5∆ disilangkan, kemudian dilakukan persilangan kembali antara ptc2∆ msg5∆ dengan msg5∆ dan dilakukan tetrad analysis. Hasil penelitian menunjuKkan bahwa hasil persilangan kembali tersebut menghasilkan pola segregasi 2:2 pada media sintetik media tanpa histidin antara ptc2∆ msg5∆ dengan msg5∆ . Hal ini mengindikasikan bahwa konstruksi double disruptant ptc2∆ msg5∆ berhasil dengan baik.Kata kunci: Saccharomyces cerevisiae, tetrad analisis, segregasi

Abstract

Rain-fed swamp is a type of freshwater swamp found in Pampangan Sub district of Ogan Komering Ilir Regency,South Sumatra, characterize by fluctuation of water level related to variation of rain precipitation. This research was carried out in Pampangan swamp by collected phytoplankton samples in 5 different month i.e. May, July, October and December 2011 and February 2012 in order to find out the diversity of phytoplankton in rain-fed swamp. Phytoplankton samples were collected by filtering 100 L swamp water through plankton net and 50 ml of filtrate were used for identification. Water quality parameters such as ph, alkalinity, hardness, conductivity, total-P, total-N, and Chlorophyll-a content also observed. The result showed that phytoplankton community in rain-fed swamp composed of 40 species member of 3 class; Bacillariophyceae (22 species), Chlorophyceae (14 species), and Cyanophyceae (4 species). Key words: Phytoplankton, rain-fed swamp, Pampangan

Abstract

Penelitian perawatan benih ikan gabus (Channa striata) telah dilakukan di Balai Penelitian Perikanan Perairan Umum Mariana, bertujuan untuk mengetahui pengaruh perbedaan padat tebat dan perbedaan volume pakan terhadap sintasan dan pertumbuhan benih ikan. Pada percobaan 1 benih ikan gabus umur 10 hari dipelihara dalam akuarium yang berisi 5 liter air dengan perlakuan 3 tingkatan padat tebar yaitu 4, 6, dan 8 3kor/l diberi pakan Moina sedangkan Percobaan 2 benih umur 10 hari dipelihara dalam wadah silinder berisi 10 liter air dengan padat tebar 4 ekor/l diberi pakan masing-masing 1,2 ml, 1,8 ml, 2,4 ml, dan 3,0 ml moina perhari. Hasil penelitian menunjukan perbedaan padat tebar berpengaruh sangat nyata (P<0.01) terhadap sintasan dan berpengaruh nyata (P < 0.05) terhadap pertumbuhan benih ikan gabus. Perbedaan volume pakan tidak menunjukkan pengaruh nyata (P>0.05) terhadap sintasan dan pertumbuhan benih ikan gabus

Abstract

An experiment was conducted in order to evaluate the effect of differentfertilizer regimes on biological productivity and water quality of limed acid sulfatesoils fishponds. The experiment consisted of 4 different fertilizer treatments i.e.,control without fertilizer input, chicken manure 50 g/m2 /week, chicken manure 75 g/m2 /week, and inorganic fertilizer (6 g of urea + 3.5 g of TSP /m /week), eachtreatment with 3 replications. Result of experiment shows that Inorganic fertilizationgave the highest chlorophyll a concentrations (83.40 mg/m3), and the highest net fishyields 7.53 kg /ha /day), but had a lower water pH than that in control. Ponds whichare fertilized with chicken manure 75 g /m2 /week gave the highest fish survival rate(100%) while in ponds without fertilizer inputs only 3.3 % of stocked fish wassurvived.

Abstract

In this work, the modification of TiO2 nanostructures based on its morphology and crystallinity phase were fabricated using a simple method. Hydrothermal growth method was used to synthesize nanorods and nanoflowers, while nanoparticles was applied using squeegee method. The average length and diameter of the as-grown nanorods were 3.5 and 46-215 nm, respectively. Meanwhile, the average total thickness and band gap value of mixed-phase TiO2 nanostructures were 15.98-24.54 nm and 2.84 eV, respectively. Based on its structural and electrical properties, the fabricated film has great potential to be applied as photoanode semiconductor layer for dye-sensitized solar cells application. Key words: TiO2, Nanostructures, Mixed-phase, Hydrothermal, Squeegee

Abstract

The use of food additive such as borax has a negative effects on health, example the abuse of borax as food additive in the pempek and bakso can be dangerous for human health at Palembang city. The borax or boric acid have toxic effect on all body cells.  The purpose of the  research is to assess the effect of borax on the quantity of mice sperm, how many are the borax doses can cause decrease the quantity of sperm mice. The research  was carried out at laboratory Department of Medical biology, Faculty of Medicine Sriwijaya University Palembang using a Completely Randomized Design. The treatment group give the borax, the control group was administrated by similar volume of aquabidest only. The result showed that borax could significantly  decreased (P<0,05) the number of mice  sperm concentration compared to control  group. As  a conclusion the administration of borax at doses 4 mg/10 gr bw and 6 mg/10 gr bw on male mice by gavage in 35 days can significantly decrease the quantity of mice sperm compared to the control  group. It is suggested  to conduct further studies such as the fertility test  of mice sperm given  borax longer than 35 days by  gavage. Key words:   Borax, The quantity of sperm and Mus musculus

Abstract

Penggunanaan tanaman sebagai obat tradisional diketahui mempunyai lebih banyak manfaat dibandingkan efek samping. Tumbuhan putri malu (M. pudica Linn.) merupakan salah satu alternatif yang dapat digunakan sebagai obat tradisional penyakit kulit. Telah dilakukan penelitian tentang pengaruh ekstrak akar tanaman  putri malu dalam menghambat pertumbuhan bakteri S. epidermidis sebagai salah satu penyebab penyakit kulit. Akar dari tanaman putri malu mengandung senyawa saponin, tannin, alkaloid dan flavonoid. Senyawa-senyawa tersebut digunakan sebagai bahan dasar obat antibakteri. Hasil penelitian menunjukkan bahwa ekstrak akar putri malu berpengaruh sangat nyata menghambat pertumbuhan bakteri S. epidermidis. Pada konsentrasi 90% ekstrak akar putri malu merupakan konsentrasi yang paling optimal dalam menghambat pertumbuhan bakteri S. epidermidis.
