Society responded to the virus epidemic in other ways. In Indonesia, after President Joko Widodo announced the primary case of coronavirus infection in two residents of Depok, the market immediately ran out of masks and hand sanitizers.
Moreover, the scarcity of those two products causes the value available in the market to skyrocket. This makes people reluctant to purchase. Nevertheless, people not must worry as hand sanitizer could be prepared at home.
This was demonstrated by the top of the Department of Pharmacy on the Faculty of Pharmacy at UNAIR, Dr. Retno Sari, M.A., Ph.D. On Wednesday, March 4, at her office, Retno Sari explained that the production of hand sanitizers requires materials resembling alcohol, glycerol as an antibacterial and moisturizing agent to forestall hands from drying out, and aquadest.
“The alcohol composition is about 70 percent, glycerin 15 percent and the rest is the most watery,” she said.
If we calculate the quantity of every of them – she added – we want 73 milliliters of alcohol, 15 milliliters of glycerin and 12 milliliters of aquadest. From the warehouse – she added – you’ll have the option to acquire 100 milliliters of hand disinfectant.
Regarding how one can prepare it, Retno Sari explained firstly that glycerol is a bit thick and wishes to be diluted with distilled water first. When the mixture becomes a little bit sticky, steadily add latest alcohol, mixing gently until all ingredients are combined.
Moreover, Retno Sari also explained that the outcomes of the mixture can already be utilized in hand sanitizers. She also said it may very well be placed in a sprig can to make it easily portable.
“So just spray it,” she said. Finally, Retno Sari also mentioned that finding these materials available in the market may very well be difficult because the community was in a rush to buy alcohol. However, Retno Sari offered alternative materials that could be used for hand disinfection, i.e. Piper betle Linn leaf extract.
“If you want to make it easier and more natural, people can use betel leaves as an antibacterial or hand sanitizer,” he said.
For this reason, Retno Sari also explained how one can make hand sanitizers from betel leaves. According to him, the betel leaf is roughly chopped and placed in a container. Then take a pot full of water and convey it to a boil. Then place the container containing the betel leaf over the teaching water and warmth for as much as half-hour until the betel leaf extract comes out.
“You do not have to make use of all of the present extract. Take as needed, for instance just 10 milliliters, then dilute with water. This solution can already be used as a hand disinfectant and easily sprayed,” she concluded.
