Abstract

The aim of this research was to know the effect of length of A3-51 probiotic  supplementation  to the number   of   intestine   Enterobacteriaceae.   Research   used   experimental   method   using   Completely Randomized  Design  which  was  based  on  4   treatments  i.e.  La  (without  probiotic),  Ll  (probiotic supplementation for 7 days), L2 (probiotic supplementation for 14 days), L3 (probiotic supplementation for 21 days). Each  treatment was repeated 3 times. The result showed that the length period of A3-51 probiotic   supplementation  very   significantly  (P<0,01)  increased  the  intestine   Enterobacteriaceae number. However, in the same time the amount of pathogenic Enterobacteriaceae decreased. In addition, probiotic supplementation improved protein, fat, and carbohydrate digestions.   Key words: Enterobacteriaceae, intestine, probiotic, nutrient digestibility

Abstract

ABSTRACT: Changes in the development of the built area of ??Kota Pariaman can be seen in 1982 covering an area of ??269.42 Ha, continuing to grow to 493.71 Ha in 2003. According to the developer, the growth of the built area in Kota Pariaman is influenced by economic factors (profit) and safety and comfort factors, namely considering safe areas from the tsunami disaster and free from flooding. While the community believes that the influencing factor is the proximity factor to public facilities and social facilities because of the completeness of the types of facilities many are located in the city center as well as the accessibility factor of the downtown area which has infrastructure conditions the good one. The problems in this study are; a) how is the carrying capacity of the North Pariaman District and b) how the direction of land development plan is in accordance with the carrying capacity of the land. The research objectives are a) analyzing land capability and b) formulating direction for land development plan in accordance with land capability in the District of North Pariaman. This type of research is descriptive research, GIS analysis methods and map overlays and analysis of land capability and land carrying capacity. Based on the physical condition of North Pariaman Subdistrict, Pariaman City, Land capability class 3 is a medium development capability class (C) and a maximum land cover ratio of 20%, the development direction is to limit the area built up and directed for non-settlement cultivation

Abstract

This study explains the Indonesian economy recently experienced a weakening or slowing in the first quarter of 2015 that showed economic growth of 4.7 percent. It is certainly believed to be caused by internal and external factors, which impacted on the Indonesian government spending either in 2015 or in 2016. This study uses time series data. Furthermore, stationary and cointegration tests were analyzed using multilevel regression model with Ordinary Least Square (OLS) and an Error Correction Mechanism (ECM) model. The results of this study will determine the internal and external factors that strengthen or weaken the relationship between the economy and government spending in Indonesia. Thus, based on these findings, policy in overcoming economic difficulties can be determined and local and central government budget for 2016 can be established.

Abstract

Probiotic is live microbial cells supplementation that has beneficial effect to the host. Feeding adult pigeons (Columba livia) with food supplemented with probiotic, Lactobacillus sp., at concentration 106,108, and 1010 cells g-1 respectively have been done in order to improve the immunologic quality of the squabs. Immunologic response namely the number and activity of kidney’s macrophage were examined. Also, the pathologic signs which developed following artificial infection by intramuscular injection with Escherichia coli suspension was examined. The result indicated that adult pigeon feed with food containing probiotic have beneficial effect to the squabs (through cropmilk) by improving their immune response namely increasing the number of kidney’s macrophage and their in vitro phagocytic activity. Also, it reduced the E. coli population in the squabs’ gut. (Animal Production 6(2): 11-124 (2004) Key Words: pigeon squab, probiotic, Lactobacillus sp., immune response

Abstract

Objectives of this research was to know the effect of probiotic A3-51 supplementation on food to the total number of bacteria in kidney and mortality of Oreochromis niloticus after challenge test with Aeromonas hydrophila and Aeromonas salmonicida achromogenes. This research was consisted of two experiment, the first was to know the highest immunity level of fish based on the number of macrophage and its phagocytic activity. Meanwhile, the second was to know the immunity level of fish challenged with A. hydrophila and A. salmonicida achromogenes by intra-peritoneal injection. The experiment used Completely Randomized Design in triplicates. The result from the first experiment showed that the highest non spesific immune system response, by means number of macrophage, was found 21 days treatment. The second experiment showed that the highest total number of bacteria in kidney and mortality level were 20.23 x 108 cells/g and 46.67%, respectively, both was found in control fish injected intra-peritoneally with A. salmonicida achromogenes.

Abstract

Probiotik Aeromonas sobria A3-51 terbukti telah mampu menekan insiden infeksi Aeromonas hydrophila dan A. salmonicida pada berbagai jenis ikan in vitro. Aplikasi melalui pakan mengalami banyak kendala oleh sebab itu dicari metode alternatif dengan menggunakannya untuk memanipulasi komponen mikroba penyusun perifiton pakan alami ikan pada substrat bambu. Dari penelitian yang dilakukan terbukti A. sobria A3-51 mampu mempengaruhi karakter biofilm perifiton serta mikroba pada lingkungan perairan ketika dilakukan di kolam tanah. Faktor lingkungan cukup berpengaruh pada kualitas air seperti penetrasi sinar matahari, pH, dan suhu. Hasil analisis proksimat menunjukkan bahwa protein perifiton cukup tinggi mencapai 22,88%-27,90% sehingga potensial digunakan sebagai bahan pakan pengganti. Adapun dari aspek imunitas, terbukti A. sobria A3-51 mampu menghambat pertumbuhan beragam bakteri Gram-negatif patogen ikan. Ketika dilakukan pengujian secara in vitro terhadap ikan tilapia, hasil belum menunjukkan bukti bahwa perifiton mampu meningkatkan derajat imun ikan tilapia berdasarkan gambaran darah

Abstract

Gold in nature is covered by rocks which contain sulfide minerals such as pyrite, chalcopyrite, arsenopyrite, and others sulfide minerals. Chemolithotrophic bacteria have the ability to oxidize the sulfur compounds and can be used in the process of releasing gold from carrier rocks which contain sulfide minerals. This research aimed to explore and identify the chemolithotrophic bacteria from gold mining areas as well as determine their potential for sulfur oxidation. The methods used in this study were exploring the potential of bacteria in sulfur oxidation and describing the variety of bacteria that were isolated from gold mining areas by 16s rRNA identification. The results showed that there were six isolates from isolation with Starkey solid medium, i.e. Bl-1, B1-2, B1-3, B1-4, B1-5 and B1-6 that were similar to Paenibacillus sp., Enterobacter ludwigiis train E8-13, uncultured Burkholderia sp., Uncultured bacterium clone N4.5, Bacillus subtilis strain CICC 10023, and Bacterium enrichment culture clone 02 respectively. The B1-3 isolate showed the highest increase of sulfate compound in the medium (8.04 % at 649.55 ppm). This indigenous bacteria will be able to be used to release gold from rock which contains sulfide minerals and reduce the use of hazardous chemicals commonly used in gold mining.
