Abstract

Chicken meat is a source of animal protein for humans. The aim of this study was to detect pathogenic bacteria in chicken meat sold at the Silver Plain traditional market. The method used in this study is descriptive because research that describes the characteristics of a population or a phenomenon that is the object of research is trial and error. From the observational data analyzed descriptively as many as 10 samples from 10 traders obtained from the silver overlay market found the presence of Salmonella sp and Escherichia coli bacteria. The results showed that the highest number of colonies was found in trader 10, namely 3.8x106 cfu/g and the lowest in trader 5, namely 3.9x104 cfu/g, this was not in accordance with the maximum limit of microbial contamination in foodstuffs (fresh chicken meat) according to the National Standard. Indonesia (SNI) 7388:2009 namely TPC 1 x 106 colonies/gram. The results also showed that 70% of the chicken meat samples were contaminated with Salmonella sp bacteria, and 60% of the samples were contaminated with Escherichia coli bacteria. This shows that the quality of chicken meat sold in the Silver Plain traditional market does not meet the Indonesian National Standard (SNI) 7388:2009 Escherichia coli 1 x 101 colonies/gram, and Salmonella sp negative/25gram

Abstract

The ileum is part of the small intestine that functions as the absorption of food and for the growth and development of bacteria to degrade feed, such as lactic acid bacteria. The purpose of this study was to explore and detect proteolytic bacteria from the ileum of Gallus gallus as a candidate probiotic agent. The research method is a selection of proteolytic bacteria, catalase, and motility. The results showed that the average proteolytic index in isolates GP sp. 4, GP sp.3, and GP sp. 1 were 1.533, 1.531, and 1.500. Nine isolates were gram-positive and one gram-negative (GP sp. 3). The ten isolates could hydrolyze hydrogen peroxide, as indicated by the formation of air bubbles. The motility test showed that eight isolates were motile and the other two isolates were non-motile (GP sp.8 and GP sp.10). The ten proteolytic bacterial isolates obtained did not have the potential to be used as probiotic agents for fermented poultry feed because low proteolytic index value.
