Microorganisms are living things that are capable of infecting humans,
animals and plants and can cause diseases ranging from minor infections to
death. One of the animals that carry microorganisms is the House Fly (Musca
Domestica ). If a food or drink is contaminated with bacteria carried by flies, it
can cause a disease. That's why researchers want to see how many microbes are
located on each wing of the house fly (Musca Domestica).
In this study, wing flies (Musca Domestica ) samples were used by
random sampling in the population. Samples needed seba n yak 3 samplethat is
right wing, left wing, and right wing and wing left the house fly (Musca
Domestic a) . The number of wings required for each sample was 7 wings
immersed in sterile 50 ml aqudest for 15 minutes. Furthermore, a microbial
contamination test was performed to see differences in the number of microbes
present in each sample with the Coliform ALT, AKK and MPN test methods .
The results of the study on the three samples showed different amounts
of microbial contamination in each sample. With the highest value located in
sample III, it is sterile aquadest with the addition of the right wing and left wing
of the house fly (Musca Domestica) . And the lowest result is located in sample II,
namely sterile aqudest with the addition of wing flies to house flies (Musca
Domestica).8
