Abstract

This research about the isolation and identification Vibrio sp from sunu grouper fish (Plectropomus leopardus). This research aimed to observe the amount of vibrio bacteria species based on colony morphology and identificate morphological colony of vibrio isolated from grouper sunu fish (Plectropomus leopardus). Bacteria isolation was conducted by isolate some external organs (lesion on its body) and internal organ (jejenum) from grouper sunu fish (Plectropomus leopardus). Bacteria was grown on selective medium for vibrio, TCBS (Thiosulfate Citrate Bile Sucrose) agar. The incubation time was 24 hours at 30 C then the morphological colony was observed and biochemestry test was done. Morphology characteristic and biochemistry test result was matched with bacterial characteristic on Bargey’s Manual of Determinative Bacteriology. The result showed there are 3 isolate vibrio bacteria that was coded by V1, V2, V3. V1 morphological characteristis was rounded, edge is entire, convex elevation, green colony colour with blue in the center of colony and smooth tekstur. Based on biochemistry test V1 was indetificated as Vibrio parahaemolyticus. V2 morphological characteristic was rounded, edge is entire, tortous elevation, colony colour yellow and smooth tekstur. based on the biochemistry tes V2 was indentificated as Vibrio harveyi. Morphological characteristic of V3 was Irregular; egde is Undulate, elevation hill, colony colour yellow and own the smooth tekstur. Based on biochemistry test V3 was identificated as Vibrio alginolyticus.Key words: Isolation, Identification, Vibrio, Kerapu Sunu (Plectropomus leopardus).

Abstract

Research about Study of Determination Calorie Value in Durian Fruit (Durio zibethinus) has done. This study aims to determine the calorie value of all the materials used. The materials used are durian fruit. Materials will be determined calorie performed on ripe fruit or fresh fruit and fruit that have been dried under the sunlight. Determination of calorie value using two methods: the first method: determination of calorie value by Cobra3 and method II: determination of the calorie value by joule calorimeter. The higher specific heat and heat capacity accordingly calorie value would be even higher.Key words: Specific Heat, Heat Capacity, Calorie Value, Calorimeter.

Abstract

The effect of treatment combination by heat shock (34oC) and starvation medium on embryogenesis induction in microspore culture of selected genotype of Nicotiana tabacum L.cv. Virginia was examined.The microspores which were isolated aseptically by maceration and centrifugation, were cultured on starvation medium (B medium) without sugar and nitrogen during 6 days at 34oC. The culture contained relatively homogeneous population of developed stage microspore (late uninucleate stage). The viability and development of microspore was obsevered. DAPI (4,6-diamidino-2-phenylindole) was used to stain the nucleus. Stained microspores were examined under a fluorescence microscope.The result showed that during stress treatment by starvation and heat shock (34oC) the structure of microspore change into 3 types of embryogenic microspore. Type 1 was identical to the late uninucleate microspore stage; in type 2 the vacuole of microspore was fragmented and peripheral cytoplamic pocket contain the nucleus; and type 3 the nucleus was positioned in cytoplamic pocket in the centre of the microspore.Key words: Nicotiana tabacum L.cv. Virginia, Starvation, heat shock.

Abstract

Lactic Acid Bacteria origin Bacteriocins are protein substances that generally have small molecular weight as well as bactericidal activity that has the potential to be used as biopreservatif to prevent spoilage, and inhibit the growth of pathogenic bacteria in food. Bacteriocins as biopreservatif mechanism is to form holes in the membrane. Effect of cytoplasmic hole formation is the presence of bacteriocins impact that caused the membrane potential gradient changes and the release of intracellular molecules and influx of extracellular substance. The effect causes inhibited cell growth and cell death in the producing process that is sensitive to bacteriocins. Bacteriocins will work actively in the pH range 5-8, and are stable on heating to 80 ° C and the activity was marred by the presence of proteolytic enzymes. Advantages of the use of antimicrobial bacteriocins in mengeliminer ability of pathogenic microbes and food spoilage origin of milk and meat. Application as a therapeutic substance is possible due to its antimicrobial characteristics that are not toxic, capable of inhibiting the low levels and produced by bacteria belonging to GRAS (Generally recognised as safe) which microbes are not a health risk.

Abstract

The aim of this study to determine the effect of feeding commercial rations on the final live weight, feed conversion and "income over feed and chick cost".This study uses 90 mixed sex chicken experiment with strain "Arbor acres" 707 SR. It produced of PT. Satwa Utama Raya (SUR), Maros and maintained for 6 weeks. They treatmented with 3 (three) rations : 1) Rx = feeding  rations manufactured by PT. X, 2) Ry = feeding rations manufactured by  PT. Y and 3) Rz = feeding rations manufactured by PT. Z. There are 5 (five) repetition for each treatment. The parameters are the final live weight, feed conversion and "income over feed and chick cost". The data are processed with a range of RAL and continued analysis of LSD when the results are significant.The result showed that the use of commercial rations are not significant to the final live weight, feed conversion and “income over feed and chick cost.

Abstract

Cassava waste is well known as one’s of agroindustry waste. Cassava waste can caused pollution because its high water. It’s make microorganism can grow well in the waste and produce odor to environt. That’s cause a serious pollution problem if we don’t care to the waste. Cassava waste  potential to be a feedstuff but its low nutrition need some treatment to enhance the nutrition. Cassava Waste high in fiber and low protein. Several research have done to know how far cassava waste can used as a feedstuff. As the research, applied biotechnology to the cassava waste enhance crude protein about 1000% , reduce crude fiber and HCN. The other hand, cassava waste fermented increase amino acids and vitamins. Poultry Feeding cassava waste fermented can support performance and productifity of broiler and laying hens. Kata kunci:Cassava waste, rations, poultry.

Abstract

This article aim to study process design having the character of steady (robust design), in the effort is optimal overall of or response. Applying method merging between inner arrays and outer arrays in one matrixes designs so-called combined arrays can close over insuffiency from products arrays. Taguchi based on the design made by response model as design of experiments integration Taguchi with method of surface of response ( RSM), then determine valuation mean response variance and response based on the response model appraiser. Some bottoms design of experimentses evaluated by using criteria Variance dispersion graphs (VDGs) with amount of appropriate experiment. Application earnings yield indicate that modified CCD have variance slope compared is smaller with bottom design MR. But, from Prediction scale earnings yield Variansi Residual maximum and the average of design augmented MR compared by is smaller modified CCD. So that design augmented MR consider as effort cost effective and time, because amount of point of small relative experiment. However in general both the design is proper consider, if paying attention to earnings yield from minimum variance..  Keyword:Robust-Variance-Dispersion-Graphs ( VDGs), multirespon, combined-array,

Abstract

This research is aim to know the effect feeding of cloves powder (Syzygium aromaticum ) to the performans of the chickens. This research involved 84 broiler chickens that are divided into 4 (four) treatments by the addition of cloves powder of Syzygium aromaticum 0,5%, 0,75%, 1,0%, and 1,25% to the ration. Each treatment was repeated 3 (three) times. Each treatment contain 7 (seven) chickens. Performans that measured are feed consumption, body weight rate and carcas percentation. Data analysis using variance/anova of the Completely Randomized Design (CRD). These results indicate that the addition of cloves powder (Syzygium aromaticum) has no real effect of the Performans of the chickens (P>0,05)
