Abstract
Garlic (Allium sativum L.) has many benefits in medicine such as antioxidant, antiviral and antibacterial activity, and inhibiting tumor growth. Garlic and PVP were blended to produce fiber. PVP was used to protect the properties of garlic. One of the methods to produce fiber of PVP/GE composite is using rotary forcespinning. Rotary forcespinning has been proven to increase production of polymeric nanofibers. The objective of this study was investigated the effect of a rotational speed of PVP/GE fiber toward morphology of PVP/GE fiber using a rotary forcespinning. PVP solution was synthesized by mixing 15 wt% PVP with aquades. The synthesized of PVP/GE with garlic extract in ratio of 10 : 5 (w/w). Various of rotational speed were 10,000, 11,000, 12,000, 13,000, 14,000, 15,000 and 16,000 rpm. The average diameter of PVP/GE fiber was investigated with optical microscope. It shows that the fiber diameter decrease with the increase of rotational speed. The result of fibers were smooth, no beads and uniform. Fourier Transform Infrared (FTIR) spectrum present the functional groups of PVP/GE fiber.
