Silver Nanoparticle Synthesis and Characterization for the Treatment of Ganoderma Fungus

Abstract

Almost every producing country's Gross Domestic Product (GDP) has benefited from the large-scale growth of the oil palm industry in recent years. However, there are a few risks to the palm trees that can have an impact on the GDP of our nation, one of which is the disease known as Ganoderma Basal Stem Rot (BSR). The lignin trunk of palm trees is broken down or degraded by a specific fungus called Ganoderma Boninense, Therefore, silver nanoparticles (AgNPs) have been created for this purpose due to their potential for treating fungus. The AgNPs were synthesized into a spherical shape by using Silver Nitrate (AgNO3), Sodium Borohyrdide (NaBH₄), and Polyvinylpyrrolidone (PVP) due to its straightforward and adaptable setup. Regarding to the AgNPs characterization, the optical properties showed the greatest absorption peak of transverse suface plasmon resonance (t-SPR) for AgNPs is 2.670 intensity at wavelength of 420nm. The structural properties of AgNPs exhibit an intensity peak as indexed (1 1 1), at 2(Theta) = 38.10°. The surface density for morphological properties is 0.1211 ± 0.000333. The study shows that 25.17% of fungal growth around Negative Control area, 2.09% around AgNPs Control area, and 0% of fungal growth around Positive Control area during the disc diffusion experiment after 7 days.
