Parkia-tizer

During the Covid-19 pandemic, a biosanitizer is needed which can be the first protection. This biosanitizer can not only protect yourself, but also an efficient one is needed to be carried anywhere and anytime. For this reason, a hand sanitizer is made which can be made from organic waste materials and can be found in the surrounding environment, namely skin waste from the plant Parkia speciosa (petai). Petai peel contains phytochemical compounds that can stimulate the immune system and increase the binding of antibacterial and antiviral carcinogens. This study aims to determine the use of petai peel extract waste as a hand sanitizer that plays a role in the Covid-19 pandemic by looking at the potential for flavonoid compounds contained in Parkia speciosa. The collected petai skin is cut into small pieces and dried under the sun. Then blend it to form a fine powder. The fine powder is macerated for 3 days using 70% ethanol, stirred and silenced periodically. Then distilled so that the remaining liquid without fine powder. Then heated at a temperature of 27 ° C on a furnace so that a thick extract is formed and then dried it. (evaporation). The extract was diluted with concentrations of 20 mg / ml (B1), 50 mg / ml (B2), and 100 mg / ml (B3). The available extracts were able to undergo antivirus activation by testing the activation of the bacterial inhibition zone by Escherichia coli using wells methods. The diluted extract, strict on a tasteless white agar medium inoculated with Escherichia coli. Samples were incubated for 20-24 hours at 37°C. The 70% ethanol extract of petai peel was able to inhibit the growth of Escherichia coli with an average of bacterial inhibition zone activation.
