Abstract

This research aims to find out the quality of curled satay in terms of Staphylococcus aureusthat are spread around in the traditional markets of Karangasem, Bali. Samples of the curled satay were taken from the 4 regions in Karangasem (Selat, Rendang, Sidemen, and Seraya), every region takes 1 traditional market and every market are owned by 2 salesman. The method used in this study is the method of Platting Method (Pelczar and Chan, 2005).  The results shows that the highest of curled satays in traditional markets of Karangasem is found in S. aureusbacteria was obtained for up to 73 x 102 CFU/g found in Sinduwati market, Sidemen on salesman 1 and 57 x 102 in Seraya Tengah market, on salesman 1. Based on the tests that has been done shows that a number of curled satay sold in traditional markets of Karangasem, Bali has exceeded the threshold amount Indonesian National Standard. The maximum lilit of microbial impurities in satay ready consumption for S. aureusbased on Indonesian National Standard is 102CFU/g.

Abstract

Escherichia coli O157:H7 and Staphylocccus epidermidis are bacteria that can cause disease in humans. Alternative control efforts are very important because the use of antibiotics can cause adverse side effects. This study aims to obtain extracts of white galangal (Alpinia galanga L.) in inhibiting the growth of E. coli O157:H7 and S. epidermidis. In this test, white galangal extract was macerated with three solvents at different polarity levels (96% ethanol, n-hexane and ethyl acetate). The ability of white galangal extract in inhibiting bacteria was tested using the Kirby Bauer method (paper disc). The concentration of galangal extract tested was 0%; 5% ; 10% ; 15%; 20% (w/v), control (ciprofloxacin) and MIC (Minimum Inhibition Concentration). To determine the toxicity of the extract, the LC50 test was carried out. Meanwhile, to determine the class of compounds contained in the galangal extract, phytochemical tests were carried out using the phytochemical screening method. The results showed that white galangal extract with 96% ethanol as solvent and n-hexane was able to inhibit the test bacteria. Inhibition against E. coli O157:H7 was most effective in n-hexane solvent with an extract concentration of 20% (inhibition zone diameter 20.2 mm). while for S.epidermidis was n-hexane solvent with a concentration of 20% (inhibition zone diameter 23.5 mm). LC50 against E. coli O157:H7 with 96% ethanol and n-hexane as solvents 11.2% and 10.4%, respectively. Meanwhile, the LC50 of S. epidermidis with 96% ethanol and n-hexane solvents were 9.9% and 9.3%, respectively. Qualitatively, white galangal plant extract contains a class of flavonoid compounds, saponins, terpenoids, and tannins.

Abstract

This study aims to find out the potency of garlic extract (Allium sativum L.) to the growth of Colletotrichum acutatum fungus which cause rot of red chili fruit post-harvest. The treatments were the administration of garlic extract in-vitro and in-vivo. In the in-vitro test, the inhibition of garlic extract was measured using well diffusion method. The in-vivo test was conducted by measuring the diameter area of C. acutatum on red chilies after treatments. The concentration of garlic extract given was 15%(b/v), 20%(b/v), 25%(b/v), 30%(b/v), and 35%(b/v) with positive control of synthetic fungicides and negative control of ethanol solvents 95% and 4 times replications. The average diameter result on the 25%(b/v) concentration of bland power test had the most effective bland zone diameter of 20.1±0.08. Statistically different was real (P?0.05) with negative controls. While in vivo tests the average area of infection area at a concentration of 35%(b/v) had an average diameter area of infection area which was best in inhibiting the growth of C. acutatum fungus.

Abstract

iThis researchhaimed to determineethe potency off Trichoderma asperellum TKD ffiltrate in inhibiting Aspergillus parasiticus contamination in peanut seeds. The treatment given to A. parasiticus was done in vitro and in vivo. In vitro there were three types methods, dual culture and the inhibition test of the T.asperellum TKD ifiltrate using the diffusion well and the colony method with concentrations of 40% (v/v), 50%(v/v), 60%(v/v),70%(v/v) and 80%(v/v). While in vivo, it was done on peanut seeds added T.asperellumiTKD filtrate with some concentrations similar to the treatment given in vitro. The parameters measured in vitro test were determined through PIRG (Percentage Inhibition of Radial Growth) and diameter inhibition zone, in vivo test parameter was the A. parasiticus colony populations. The results showed T.asperellum TKD filtrate significantly (P?0,05) was able to inhibit A. parasiticus growth iin vitro and iin vivo. The percentageeof T.asperellum TKD bland power against A.parasiticus in vitro with the highest dual culture method was 60.65%. In the method of colony and diffusion well, the concentration of 80% was the highest concentration in inhibiting A. parasiticus, which were 83.00±1.60% and 15.09±0.12 mm. T.asperellum TKD filtrate with a concentration of 80% added to peanut seeds had the highest inhibition on the number of population of A. parasiticus colonies with a percentage decrease of 88.3%.
