Abstract

Corona virus disease (Covid-19) is a disease caused by a virus that attacks the respiratory tract and still continues today. The death toll from Covid-19 continues to rise in Indonesia as the number of positive cases of the coronavirus reaches thousands of people. One of the bacterial infections that cause respiratory infections is Klebsiella pneumoniae. One of the preventive efforts to prevent the spread of infections caused by the corona virus and bacteria is the renewal of waterless hand sanitizers called antiseptic hand sanitizers or hand sanitizers. The approach method used is to provide understanding to the students about the potential of waste treatment in the city of Bontang. Continue by socializing the manufacture of chitosan from shrimp shells and the process of processing chitosan to produce hand sanitizers. From the results of this training, it can be concluded with enthusiasm from the students that the activities are carried out well and are able to increase students' knowledge about the potential of waste in the surrounding environment and it is hoped that they will be able to practice making hand santizers on a simple scale. Keywords: Chitosan, Hand Santizer, Alcohol-Free, Islamic Boarding School Students.

Abstract

Desalination (removal of salt content) of salt or brackish water into fresh water is another way to obtain fresh water. The two most widely practiced methods are distillation (distillation), heating seawater until it evaporates and then condensing to get fresh water and reverse osmosis, seawater at high pressure through a thin membrane to pass water molecules. Another method that can be used in the desalination process is the adsrobtion process. One of the media that can be used in the adsrobtion process is chitosan. This research is carried out by the bacth method with two variables, the first variable concentration, namely 800, 1600, 2400, 3200 and 4000 ppm. The second variable is the stirring time with variations, namely 100, 200, 300, 400 and 500 rpm. Based on the results of studies that have been carried out, the best concentration of shrimp skin chitosan is at a concentration of 4000 mg / L or the addition of 200 mg of chitosan in 0.25 L of brackish water. At this concentration, the absorbent can reduce the salinity of brackish water by 86.6694% and for the best stirring speed the shrimp shell chitosan is at a speed of 300 rpm with the addition of 1000 mg of chitosan in 0.25 L of brackish water. At this stirring speed, the adsorbent can reduce the salinity of brackish water by 82.6335%.
