This study aims to determine how the pH, water holding capacity and the Eber test or rot test on duck meat which taken in several traditional markets in Kediri Regency. The samples were taken as many as 30 samples from 3 different markets. From each market taken as many as 10 different samples in each market. The type of research is quantitative and descriptive using qualitative laboratory examinations. The results showed that for the pH test and water holding capacity there was no significant difference from the three markets, but in the Eber test that was carried out there were several positive and some negative samples. This is due to several factors that refer to the process of slaughtering animals, the type of animal, and the lack of sterilization of slaughterhouses and the lack of understanding for the community, therefore it is important to improve the quality of products that are safe, healthy, whole, halal.

The purpose of this research aimed to determine the antibacterial effectiveness of the methanolic extract of dragon scales leaves (Drymoglossum piloselloides) against MRSA (Methicilin-resistant Staphylococcus aureus) and Eschericia coli bacteria in vitro using the diffusion method. This research used a population of Methicillin-resistant Staphylococcus aureus and Eschericia coli bacteria. The sample to be used is dragon scale leaf methanol extract. The method in this research used experimental with 6 treatments, namely dragon scale leaf methanol extract with concentrations of 45%, 55%, 65%, 75%, negative control (methanol) and positive control  (chloramphenicol antibiotics). Data collection in this study was carried out by recording the diameter of the inhibition zone using a caliper (mm). The data obtained from the diameter of the inhibition zone of 75% extract variation resulted in an inhibition zone of 17.02 mm (in MRSA) and 8.47 mm (in E.coli). Chloramphenicol was found to be resistant to MRSA, but sensitive to E.coli. Data analysis used  ANOVA test which statistically showed that there was a significant difference (P<0.05) in the diameter of the inhibition zone of the dragon scale leaf methanol extract against MRSA bacteria and there was a very significant difference (P<0.01) in the diameter Inhibition zone of dragon scale leaf methanol extract against Eschericia coli bacteria.
