Abstract

Sintesis nanopartikel perak telah berhasil dilakukan dengan mentode green-synthesis yang menggunakan campuran ekstrak daun Glycine Max (L) Merr dan larutan AgNO3. Pada penelitian ini, nanopartikel perak (AgNPs) dikaraktersiasi menggunakan Spektrofotometer UV-Vis, SEM-EDS, dan ICP-OES. Spektrofotometer UV-Vis digunakan untuk mengkarakterisasi sifat plasmonik AgNPs, SEM-EDS untuk menganalisis morfologi dari AgNPs dan ICP-OES untuk mengukur kuantitas Ag pada sampel. Selain itu, uji aktivitas antijamur AgNPs juga diobservasi untuk menentukan efektivitas AgNPs dalam menghambat pertumbuhan jamur Aspergillus sp. Terbentuknya AgNPs ditandai dengan perubahan warna larutan dari kuning menjadi hitam. Karakterisasi UV-Vis menunjukkan bahwa terdapat dua pucak serapan maksimum dengan panjang gelombang diantara 366 nm sampai 474 nm. Pada karakterisasi SEM-EDS diketahui bahwa AgNPs memiliki rata-rata ukuran partikel 48,46±1,24 nm, dengan bentuk spherical dan tidak seragam. AgNPs memiliki persebaran yang merata pada tekstil polyester dengan presentase beratnya mencapai 5,3%. Karakterisasi ICP-OES menunjukkan bahwa konsentrasi Ag yang terkandung pada sampel AgNPs adalah 71-4550 mg/Kg. AgNPs dapat menghambat pertumbuhan jamur Aspergillus sp. dengan membentuk diameter zona hambat sebesar 14,9 ±1,26 mm. ================================================================================================================== Synthesis of silver nanoparticles has been successfully carried out by a green-synthesis method using a mixture of Glycine Max (L) Merr leaf extract and AgNO3 solution. In this study, silver nanoparticles (AgNPs) were characterized and analyzed using UV-Vis spectrophotometers, SEM-EDS, and ICP-OES. UV-Vis spectrophotometer was used to characterize the plasmonic properties of AgNPs, SEM-EDS to analyze the morphology of AgNPs and ICP-OES to measure Ag levels in samples. In addition, AgNP antifungal activity tests were also observed to determine the ability of AgNP in inhibiting the growth of the fungus Aspergillus sp. The formation of AgNP is characterized by a change in color from yellow to black. UV-Vis characterization shows that there are two maximum absorption tides with wavelengths between 366 nm to 474 nm. The SEM-EDS characterization of AgNPs has an average particle size of 48.46 ± 1.24 nm, with a round shape and not uniform. AgNP has an equal distribution of polyester textiles with a weighting of up to 5.3%. ICP-OES characterization shows that the Ag concentration contained in the AgNPs sample is 71-4550 mg/Kg. AgNPs can inhibit the growth of the fungus Aspergillus sp. by forming an inhibition zone diameter of 14.9 ± 1.26 mm.
