The government through the Ministry of Education and Culture (Kemendikbud) has made a decision to suspend teaching and learning activities in schools.The learning process that starts face to face directly in the classroom turns into distance learning /brave.However, the government decided to reopen schools in the Covid-19 corona virus green zone for teaching and learning activities for students.The opening of special schools in the green zone will be held in mid-July 2020.School openings must be opened with strict health protocols, no updated potential for new Covid-19 clusters in schools.This is a form of application of the "New Normal" that is being adapted to the people of Indonesia.Indonesian people must consider the existence of this corona virus pandemic with new normalcy, such as using a compilation mask outside the home, always using a hand compass tool and using a loudspeaker and distance measuring device.The purpose of this study was to make an automated hand sanitizer design as an effort to improve the delivery of Covid-19 in schools.Automatic hand sanitizer is useful to facilitate the hand sanitizer liquid out of the bottle, so it is more effective to use and does not run out quickly.This study uses an Arduino Nano microcontroller as the main control, a human hand detection sensor, and a servo motor as an actuator that will activate the automatic bottle.The mouth of the hand sanitizer bottle uses an elastic hose that leads to the part where the cleaning liquid comes out.This research uses the Research and Development (RnD) method.The result of this research is an automatic hand sanitizer with a large size hand sanitizer that can be mounted into a tool with a maximum of 500 ml.This automatic hand sanitizer will automatically release the hand sanitizer fluid which approves the sensor under the user's hand protective device.
