Peperomia pellucida is one of the plants that has secondary metabolite compounds which can be used as a reducing agent in synthesizing silver nanoparticles. These objectives of the research were to study modification effect of pickled goat skin using silver nanoparticles which prepared with Peperomia pellucida extract on mechanical properties and the biodegradability. The silver nanoparticles were synthesized from silver nitrate solution and Peperomia pellucida extract by microwave, extraction, and ultrasound methods, and also were characterized by using an Ultraviolet-Visible spectrophotometer and a Particle Size Analyzer. Mechanical properties of skin were determined by tensile strength test and the biodegradability of skin was determined by biodegradation test. The silver nanoparticles synthesized by microwave method showed the absorbance peak of UV-Vis at 420?nm, ultrasound at 450?nm, and extraction at 445?nm. The average size of the silver nanoparticles synthesized by microwave method was 179.7?nm, ultrasound was 88.2?nm, and extraction was 63.3?nm. Skin after modification with silver nanoparticle by ultrasound method has the greatest biodegradability, while skin modified with silver nanoparticle by microwave method has the highest tensile strength with average for about 24.075?MPa. © 2023 Author(s).
