Abstract

Garlic has bioactive compounds that are efficacious as antibacterial (bacteriostatic) in some pathogenic bacteria, which one of them is Staphylococcus aureus. Major antimicrobial component is active on garlic especially allicin. The ability of garlic extract as anti-bacterial because of the combination of alisin and scordinin. Alisin serves as a natural antibiotic capable of killing antibiotic-resistant Staphylococcus aureus. This paper aims to study the effect of concentration of garlic juice on the growth of Staphylococcus aureus and determine the minimum concentration to prevent the growth of the bacteria. This type of research is experimental. The population and sample of this study were culture of pure Staphylococcus aureus grown on MSA medium (Manitol Salt Agar). Total sample of research are 28 samples. Staphylococcus aureus growth data were obtained by indirect observation through laboratory tests. Data analysis techniques used Kruskal-Wallis test with 5% error rate (0,05) and Mann Whitney test through SPSS 17,0 program. The result of anti bacterial test of garlic extract (Allium sativum Linn) with Kruskal-Wallis showed that there was influence of extract concentration of garlic on growth of Staphylococcus aureus (p = 0,000). While Mann - Whitney test results obtained that at 25% concentration is the minimum concentration that effectively prevent the growth of Staphylococcus aureus. Therefore it can be concluded that there is influence of extract of garlic juice on growth of Staphylococcus aureus.

Abstract

Fish is a food source that is easily damaged. The quality of fish is easily reduced because the water and protein content in fish is quite high so that it rots easily. Therefore, fish require preservation that can maintain the quality of fish, some fishermen usually use formalin as a preservative to preserve fish, but formalin is not allowed in food ingredients because formalin is harmful to health. The use of natural preservatives is an alternative choice for preserving fish. Pineapple skin vinegar is one of the natural preservatives that can be used because it contains acetic acid which functions as an antimicrobial that prevents the growth of bacteria in fish. The purpose of this study was to analyze the description of the protein content of Tuna fish (Euthynnusaffinis) preserved with pineapple skin vinegar (AnanasComosus) and NaCl formulations based on soaking variations. This type of research is descriptive research conducted by grouping fish to determine the protein content of fish incubated for 12 hours in each group. The results showed that 15-minute soaking got an average value of 9.3504%, while 20-minute soaking got an average value of 17.6214%. The conclusion is that the soaking time of pineapple skin vinegar and NaCl got different average values.
