The Green Synthesis method is widely developed due to its environmentally friendly, cost-effective, and easy application for nanoparticle-scale synthesis. Among all metal nanoparticles, silver nanoparticles are the most utilized products in the field of nanotechnology. Biomolecules contained in plant extracts can reduce the size of silver particles to nano size. This study aims to determine the antibacterial properties and activity of silver nanoparticles synthesized with the ethanol extract of mahkota dewa leaves. The formation of silver nanoparticles is monitored with UV-Vis absorption and its change in color. Parameters evaluated are shape, size, particle size distribution, composition, metal residue, and a functional group of nanoparticles, using Scanning Electron Microscopy (SEM), Particle Size Analyzer (PSA), X-Ray Diffraction (XRD), and Fourier Transform InfraRed (FTIR) instrument. The research on UV-Vis color and absorption show black silver color with the wavelength of 450-465nm. The characterization result shows spherical-shaped silver nanoparticle. Furthermore, PDI best value on concentration of 0.125% is 0,221±0,0482 with average particle size of 130,300±12,6858 nm. The diffraction pattern of silver nanoparticle with XRD test indicates that the nanoparticles contain the silver component. Antibacterial activity test shows that silver nanoparticles have a greater inhibition zone than AgNO3, and 0.125% ethanol extract of mahkota dewa leaves against Escherichia coli and Staphylococcus aureus. From the results of the study, it can be concluded that the ethanol extract from mahkota dewa leaves can be used as a bioreductor agent to produce silver nanoparticles which have greater antimicrobial activity compared to Ag and ethanol extract from mahkota dewa leaves.

Bioenhancers are drug facilitator which do not show the typical drug activity but in combination to enhance the activity of other molecule in several way including increase the bioavailability of drug across the membrane, potentiating the drug molecules by conformational interaction, acting as receptor for drug molecules and making target cell more receptive to drugs and promote and increase the bioactivity or bioavailability or the uptake of drugs in combination therapy. The objective of the present study was to evaluate the antibacterial and activity of combination in Azadirachta indica extract with cow urine distillate and pepper extract against common pathogenic bacteria, a causative agent of watery diarrhea. It has been found that Indian indigenous cow urine and its distillate also possess bioenhancing ability. Bioenhancing role of cow urine distillate (CUD) and pepper extract was investigated on antibacterial activity of ethanol extract of Azadirachta indica. Antibacterial activity of ethanol extract neem alone and in combination with CUD and pepper extract were determined the ATCC strains against Staphylococcus aureus, Klebsiella pneumoniae, Pseudomonas aeruginosa and E-coli by cup plate diffusion method. Ethanol extract of neem has showed more effect on P. aeruginosa, E-coli than S. aureus and K. pneumonia with combination of CUD and pepper extract. CUD and pepper did not show any inhibition of test bacteria in low concentration. The antibacterial effect of combination of extract and CUD was higher than the inhibition caused by extract alone and is suggestive of the bioenhancing role of cow urine distillate and pepper. Moreover, inhibition of test bacteria was observed with less concentration of extract on combining with CUD
