This study was aims to determine the viability of chitinolytic bacterial isolates in some carrier media and to know the potential of chitinolytic bacterial isolates in various carrier media in controlling the disease of sprout caused by F. oxysporum and S. rolfsii on red pepper plant. The method used by measuring the viability and ability of bacteria in growing media and carrier media on MGMK media after storage of carrier media for 90 days. Bacteria NR09 has good viability on peat carrier media and palm oil bunch compostÂ and has the potential to inhibit attack of pathogenic fungi S. rolfsii and F. oxysporum.

The aim of this study was to assess the percentage of local duck spermatozoa morphology (Anas platyrhynchos) for 6 days of storage in three storage mediums combining various egg yolk (EY) concentrations.This experimental study applied three combinations of factors as treatment. Medium (Tris, PBS or Ringer lactate), egg yolk (EY) concentration 0,5,10,15 or 25% and storage time (0,1,2,3,4,5,6 day). Spermatozoa obtained by sequence method, ejaculate or sperm obtained in swim up in medium, swim up spermatozoa were used for treatment in storage medium according to treatment and assessed before and after morphology of storage in refrigerator temperature (50 C). The results showed that spermatoza morphology was significantly different (P <0.01) between 15 treatments. The medium factor and concentration of EY significantly (P <0.05) affected the morphology of treatment spermatozoa. The highest percentage of highest post-preservation spermatozoa morphology for six days was obtained in 5% yolk treatment in PBS medium (5EYPBS). This study proves that egg yolk cryoprotectants are good for maintaining the morphology of local duck spermatozoa.

The effect of sulphuric acid fermentation of processed palm oil bunch hydrolysis and on ethanol and sugar production was conducted. The aim was to investigate the hydrolytic optimum required by Saccharomyces cerevisiae for ethanol and sugar production. About 12.5 g powdered palm oil bunch was used in this experiment. The powder was hydrolized several times using sulphuric acid in several concentration. Sugar, product ofÂ hydrolysis, was detected every one hour using spectrophotometer. The sugar was fermented by Saccharomyces cerevisiae and incubated for several days. Results showed that 2-4% sulphuric acid was oprimum concentration for 30 g/L sugar production. The highest ethanol production 4.94% occurred after two days fermentation.

This research objective is to identify the effects of wungu leaf extract (Graptophyllum pictum L. Griff) on the fertility index and spermatozoa of normal morphology in male rat ( Rattus novergicus.L). Fifteen male and 45 female rats of 9 to 10 weeks old were used as research samples. The fifteen male rats were divided into five treatment groups of wungu extract dosage: control I (0mg/KgBW), control II (0.5ml olive oil), dosage 1 (100mg/KgBW), dosage 2 (200mg/KgBW), and dosage 3 (400mg/KgBW) for 60 days. The extract was given orally and each group consisted of three test rats as repetition. On the day 55 to day 60, each test male animal was mated with three female rats. After 60 days, an observation was done to 15 male and 45 female rats to identify fertility index. Normal spermatozoa morphological observation with microscope. The data obtained were tested by Analysis of Variance Test (ANOVA ? = 0.05) and Duncanâs Multiple Range Test (DMRT). Based on the observation and statistical analysis, it was found that wungu leaf extract of different dosages did not give significant effects on fertility index but have significant effects on spermatozoa of normal morphology. This was proven by the fact that the higher the dosage given, the worse the spermatozoa of normal morphology. Based on Linear Regression Analysis, it was found significant correlation between dosage variation extract of wungu leaf and fertility index, and number of normal spermatozoa.

The aimed of this research was to investigated human intestinal bacteria (Streptococcus faecalis, Eschericia coli, Salmonella Sp., and Vibrio fischeri), to investigated dose of tartrazine, and to investigated biotransformation of tartrazine by human intestinal bacteria (Streptococcus faecalis, Eschericia coli, Salmonella Sp., and Vibrio fischeri). The method of this research was experiment with significant correlation to investigated biotransformation of tartrazine by human intestinal bacteria (Streptococcus faecalis, Eschericia coli, Salmonella Sp., and Vibrio fischeri). This study is primarily focussed on made bacteria medium, made standart inoculums of bacteria, and evaluation for activity of human intestinal bacteria (Streptococcus faecalis, Eschericia coli, Salmonella Sp., and Vibrio fischeri). The results obtained were attributed to the human intestinal bacteria was used in this research was biotransformated tartrazine. From the results that had been increase dose of tartrazine correlation with increase biotransformation by human intestinal bacteria. Highest dose of tartrazine was 15 mg, and highest biotransformation by Vibrio fischeri, which rate of zone decolourisation diameter was 1,22 cm, and rate of zone decolourisation was 1,44 cm2. Statistically showed significantly in correlation dose of tartrazine with rate of zone decolourisation (0,001 < P < 0,05), but statistically showed non significantly in correlation bacteria with rate of zone decolourisation (0,05 < P < 0,268).

The study of extract and fraction of Peperomia pellucida (L.) Kunth., herbalâs against several dermal pathogenic bacteria have been carried out in Research Laboratory of Pharmacy Department and Microbiology and Micology Laboratory Biology Department Faculty Mathematic and Natural Sciences Andalas University and Regional Medical Laboratory Center in Gunung Pangilun Padang from July until October 2007. Three kinds of dermal pathogenic bacteria were used : Staphylococcus aureus, Staphylococcus epidermidis and Proteus vulgaris. Antimicrobial activity was determined base on their MIC (Minimal Inhibitory Concentration) and MBC (Minimal Bactericidal Concentration) through dilution method that used âMicrotiterplate 96-wellâ. The Result showed that the best activity of herbal extract was against Proteus vulgaris (MIC 7,81 ppm and MBC 125 ppm). The most active fraction was showed in n-hexane against Proteus vulgaris (MIC 0,63 ppm and MBC 250 ppm), the etil acetat fraction (MIC 2,50 ppm and MBC 500 ppm), while the activity of n-butanol and aquaeous fraction (MIC 5 ppm and MBC 500 ppm, respectively).
