The purpose of this study was to determine the potential of fluorescent pseudomonads on some carrier with the addition of stabilizer glycerol in controlling Blood Disease Bacteria invitro. The experiment was conducted from May to July 2013, housed in the Laboratory of Plant Physiology, FMIPA UNP. Parameters measured were the amount of inhibition zone diameter fluorescent pseudomonads in controlling BDB CAS3 invitro. Observations preservation is done every 10 days until a preservation period of 60 days. This study is an experiment in completely randomized design (CRD) with 9 treatments and 3 replications. The treatments were fluorescent pseudomonads carrier CAS3 on tapioca (glycerol addition of 0,03 mL, 0,04 mL and 0,05 mL); carrier CAS3 fluorescent pseudomonads in rice flour (glycerol addition of 0,03 mL, 0,04 mL and 0,05 mL); carrier CAS3 fluorescent pseudomonads on talc (glycerol addition of 0,03 mL, 0,04 mL and 0,05 mL). Inhibition zone diameter data were analyzed using ANOVA at 5% significance level and continued with DNMRT test at 5% significance level. The results showed that the large inhibitory zone formed around the Blood Disease Bacteria vary. Results of analysis of variance on the preservation period of 10 days was significantly different at DNMRT further test, with the largest inhibition zone that is in treatment F (6,41mm) and the lowest in treatment I (1.15mm), whereas the preservation period of 20 to 60 days is not significantly different. All types of fluorescent pseudomonads carrier Cas3 potential in controlling Blood Disease Bacteria invitro.Key words : pseudomonad fluoresen, Blood Disease Bacteria, Glycerol

This research has successfully designed an instrument to measure air pressure, namely, DT-Sense Barometric Pressure and Temperature (DT-SBPT). DT-SBPT is a smart sensor module on the basis of HP03 sensor. Data were collected using direct and indirect measurement. Direct measurement was done toward air pressure. Indirect measurement, however, was applied to determine the exact and accuracy of the measurement of air pressure. Data were analyzed by using two ways, namely statistic and graphic ways. The result of the research shows that DT-SBPT has high appropriateness and accuracy, which is 0.99. The air pressure around earth surface decrease linearly when the height increase.Keywords: air pressure, smart sensor module

This research theoretically describes the molecule n2 p2 with cemetery group d-h using ab initio /STO-3 G that is included in the package of HyperChem Pro.6.0. this study also discusses the effect of atom toward electronic features and the structure that is formed from molecule n2 p2. Moreover, this research investigated the effect of cemetery group n1-P2 toward molecule stability n2 P2. Research findings revealed that loop n1-P2 or loop P2-P3 could be single loop, double loop, and even triple loop. For the optimum result, the most stable molecule was CIP (E=993242,9375), that is the optimum result of CIPPCI. However, the most unstable molecule was PP (E=423494,6563), that is the optimum result of HPPH. In one group from top-down or in a period form left-right, total energy seems decrease. In other words, n2 P2 was seen more stable. Key wordS :Ab initio, molekul n2P2, grup simetri D~h

This study aims to determine the effect of the concentration of semi-solid electrolyte/polymer gel and determine the effect of the dye absorption technique on TiO2 paste the resulting DSSC efficiency. The results obtained by XRD characterization of TiO2 crystal phase is anatase and rutile TiO2 with a crystal size of 30.27 nm. Based of testing the light absorption of dye extract of purple sweet potato is known that the spectrum of the dye can absorb light at 533 nm wavelength maximum. The result of the conversion of sunlight into electrical energy obtained the highest value is at the highest PEG concentration at 0.1 M is 0,38% for TiO2 paste is mixed directly with the dye and 0,23% for TiO2 paste soaking in the dye for 24 hours using an electrolyte semi-solid/gel polymer with an area of 1 cm2.Key words: anthocyanin, DSSC, semi-solid electrolyte, FTIR, UV-Vis, XRD

This study aimed to see whether there are differences in the profile line image and the linear attenuation coefficient in the urine baby boys and baby girls who drink only breast milk alone and additional milk with computed radiography, and relation to differences in impurity law. The study was conducted in the x-ray radiology Hospital National Stroke Bukittinggi. The study sample consisted of urine male and female babies who drink only breast milk and urine only baby girls and boys who drank ation and additional milk. CR image retrieval is performed three days (22, 25 and 26 September 2014) with a voltage variation of 50 and 60 kV and 100 mA using a strong current and exposure time of 5 ms. The image was analyzed visually, and physical image quality. The results showed that visual image acquisition of the third day and with two different voltage variations indicate that there are differences in the brightness, contrast and sharpness of the image. Analysis of image quality (based grafi line profile image) shows the pattern of the same line profile image on the third day of taking images at a voltage of 60 kV. Physical Analysis of the image showed that the urine samples tested had a pattern of linear attenuation coefficient value equal to the voltage of 60 kV on three different days. Linear attenuation coefficient values greatest U1 and U3 linear attenuation coefficient on the third day of the smallest image retrieval. The big difference in the value of the significant linear attenuation coefficient between U1 and U3 sample is related to differences in the urine purification unclean baby boys and baby girls.Key words: baby boy urine, urine baby girl, computed radiography, law unclean in Islam

The effects of black tea extract on mice fertility was studied in twenty four (n=24) sexually matured male mice. Mices were randomly divide into four (4) groups of six (6) mices per group. The experimental groups ware treated as follows: Group I treated with no received treatment, Group II with 1,25 %, Group III with 2,5 %, and Group IV with 5 % black tea extract. The extract was orally administered 1 ml/100 g body weigh for 35 days. The epididymis weight, sperm count, motility, viability and normal sperm morphology changes were determined. The epididymis weight, sperm count, motility, viability and normal sperm were decreased. Treatment with highest dose 5 % of the extract resulted in a significant decreased when compared to the control. Result showed that black tea extract has potential for use as antifertility for animal in future.Key words: black tea extract, mice fertility
