Abstract

Cherry leaves are an alternative material that can be used as a natural disinfectant because they contain active com-pounds in the form of flavonoids, saponins, and tannins which can work as antibacterial compounds in duck egg hatching machines. The purpose of this study was to determine the effect of cherry leaf infusion and the most effective concentration level on the ability to reduce the number of bacteria and inhibit bac-teria in duck egg hatching machines. This research was conduc-ted experimentally using a Completely Randomized Design (CRD) and continued with the Tukey test with three treatments, namely P1 (50% concentration), P2 (75% concentration), and P3 (100% concentration) and six replications. The observed varia-bles were the decrease in the number of bacteria, inhibition zone of bacilli bacteria and inhibition zone of bacteria coccus in the duck egg hatching machine. The results showed that cherry leaf infusion had the same effect (P>0.05) on decreasing the number of bacteria and showed a different effect (P<0.05) on the inhibi-tion zone of gram positive and gram negative bacilli but had no effect on the inhibition zone gram negative and positive cocci bacteria, and cherry leaf infusion with a concentration of 75% produced the most effective inhibition zone for decreasing the number of bacteria and the ability to inhibit bacteria.

Abstract

Concentrated layer poultry farm produce manure that accumulate in one place and have the potential to pollute the environment. Manure is an organic material that is not yet stable and contains both pathogenic and non-pathogenic microbes, therefore it needs to be handled so that the organic waste material decomposes into nutrients that are stable and safe for the environment. Manure can be processed by vermicomposting, one of the requirements for vermicomposting is a C/N ratio, manure has a low C/N ratio, to increase the substrate C/N ratio, leaf litter can be added. The purpose of the study is to know the effect of C/N ratio in vermicomposting of chicken excrement mixture and foliage on the temperature changes, total number of bacteria and coliform and on the C/N balance that produces the lowest total coliform. Research was conducted using a complete randomized design consists of 3 treatment with different ratio C/N, P1(C/N 25), P2(C/N30), P3(C/N 35) which is repeated 6 times, Data were analyzed with the variance and continued with Duncan Test. The results showed that the C/N ratio balance in vermicomposting of the mixture of manure and leaf litter had a significant effect on the total number of bacteria, but had no significant effect on total coliform. The balance of C/N ratio of 30 resulted in the highest total bacterial count and the lowest coliform in the decomposition process of 60.67 x 1011 cfu/g and 12,86 MPN/mL.
