The West Sumatra, Indonesia, mascot plant is called Andalas (Morus macroura Miq.). This plant belongs to the Moraceae family, which has a long history of being used medicinally. The goal of this study was to evaluate the Andalas ethanol extract's potential to prevent the growth of pathogenic microorganisms. The Andalas stems and roots were subjected to the ethanol extraction process. A completely randomized design (CRD) was utilized to determine the ideal concentration of ethanol extracts of Andalas roots and stems for suppressing test microorganisms. In this investigation, there were four different extract concentrations used as treatments: 3.12 percent, 6.25 percent, 12.50 percent, and 25 percent. The paper disc diffusion method was used to conduct antimicrobial activity testing on the test microorganisms (Staphylococcus aureus, Escherichia coli, and Candida albicans). The outcomes revealed that the. The extract's potential mechanisms for exerting antibacterial activity against both of the studied microorganisms include flavonoids, alkaloids, saponins, terpenoids, and tannins.

The purpose of this study was to determine the optimum conditions i.e. pH and concentration of Rhodamin B and methanyl yellow using CCCR absorbent which is the result of synthesis by using the UV-VIS spectrophotometer. The method used was the adsorption method (Batch). Absorption of rhodamine B and methanyl yellow in solution by C-cinnamalCalix[4] Resorsinarena (CCCR) compound is carried out in a batch system at variations of pH 2, 3, 4, 5, 6, 7. At pH 4,5,6 the amount of H + in the solution is more so that H + competition with rhodamin B is suspected to bind to the functional groups. Ion H+ prevents rhodamine B from reaching the surface of the functional group, so the absorption at these pH is low. At pH 7 occurs the competition of complex formation reaction between chelate compounds with hydroxide ions and this is the optimum pH, while the optimum pH of methanyl yellow occurs at pH 3. Variations in the concentrations of rhodamine B and methanyl yellow are carried out at their optimum pH with variations of 20, 50, 100, 150 and 200 mg / L. The amount of rhodamin B extracted increases with increasing concentration and reaches a maximum absorption value of 1.6235 mg / g at a concentration of 100 ppm.

Andalas (Morus macroura Miq.) is a West Sumatra, Indonesia mascot plant. This plant is a Moraceae group, which is widely used traditionally as a medicinal plant. The purpose of this study was to determine the potential of Andalas ethanol extract in inhibiting the growth of pathogen microbes. Ethanol extraction was done to the roots and stems of Andalas. To see the optimum concentration of ethanol extracts of Andalas roots and stems in inhibiting test microbes, a completely randomized design (CRD) was used. The treatments given in this study were extract concentration of 3.12%, 6.25%, 12.50%, and 25%, respectively. Antimicrobial activity tests were carried out on test microbes (Staphylococcus aureus, Escherichia coli, and Candida albicans) using the paper disc diffusion method. The results showed that the optimum concentration of Andaleh root ethanol extract in inhibiting the growth of S. aureus and E. coli was at 12.5% and 3.125%. Meanwhile, the best concentration of ethanol extract of Andaleh stem in inhibiting the growth of S. aureus and E. coli was at 25%. There was no antimicrobial activity of the ethanol extract of Andaleh roots and stem against the growth of C. albicans.
