Effect Of Peel Extract and Crown of Pineapple (Ananas comosus L.Merr) on The Growth of Trichophytonrubrum Fungus

Abstract

Trichophyton rubrum is a fungal species that often infects human skin. Treatment in healing
these infections usually uses chemical drugs sold in the market such as ketoconazole drugs. These
chemical drugs have many side effects, so there is a need for natural remedies that can replace
chemical drugs. Pineapple peel and leaf crown (Ananas comosusL. Merr) is a type of fruit part which
is a residual waste and is not used. The content in the peel and crown of pineapple leaves (Ananas
comosusL. Merr) are flavonoids, alkaloids, saponins, and tannins which have the content to inhibit the
growth of the fungus Trichophyton rubrum. The purpose of this study was to determine whether there
was an effect of extracts of the peel and crown of pineapple leaves (Ananas comosusL. Merr) on the
growth of the fungus Trichophyton rubum. This research includes experimental research using the
Kirby-Bauer method or disc paper. The treatments in this study used concentrations of 25%, 50%,
75% extract of pineapple peel and leaf crown (Ananas comosusL. Merr), negative control (0%) and
positive control (ketoconazole). Based on the Mann-Whitney test with a significant provision of 0.05,
it was found that there were differences in each treatment. These results indicate that there is an effect
of extracts of the peel and crown of pineapple leaves (Ananas comosusL. Merr) on the growth of the
fungus Trichophyton rubrum and the best concentration of inhibition zone is 75%
