INTRODUCTION
Education is very important to advance a human civilization today.
However, in 2019 there was a disaster caused by a virus or called the covid-19 virus throughout the world (Zhong et al.
The impact of this virus is very significant on the economy, health and education.
The spike in cases caused by the corona virus which started in the city of Wuhan in China and has an impact on the State of Indonesia (Nurulfa et al.
, 2021.
Aletheiani, 2021.
Nursjanti et al.
, 2021.
Marlina & Hazizah.
The government has imposed restrictions on activities or new normal for almost 2 years, but the spike in exposure to COVID-19 continues to grow.
This makes learning during COVID-19 forced to use online learning without face-to-face learning (Susilana et al.
, 2020.
Churiyah & Sakdiyyah.
Abidah et al.
, 2.
This makes the government make various efforts to achieve the effectiveness of online learning such as providing free internet packages and the use of online learning media such as zoom, cloudx, google meet and google classroom and others, which are greatly facilitated and fully supported by the government (Rulandari, 2020.
Fahrurrozi et al.
, 2021.
Wajdi et , 2.
However, the use of technology is not without problems, there are many variances of problems that hinder the implementation of effectiveness, one of which is that many students to students who live in remote areas, and are left behind make the internet network very slow to access or sometimes the signal is often completely dead.
This makes students very overwhelmed in conducting online lectures (Zhong et al.
, 2020.
Bestiantono et al.
, 2020.
Dwiaryanti & Rahman.
From other aspects, for example, elementary to high school students, from field findings, it was found that there was a lack of control over the use of cellphones from parents, so these students misused the use of internet packages provided by the government such as being made to play online games which resulted in a decrease in the quality of students and students.
in gaining knowledge (Hidayat et al.
, 2020.
Rachmadtullah, 2.
Parental guidance during this pandemic is highly expected because the closest control is parents so that learning can be achieved.
In addition to the lack of effective learning in the field of theory, it also has an impact on learning problems in the field of practicum where many students, especially in the vocational field, do not understand the practice in the field, which means that in the field of education, technical output skills are very necessary for their application in the industrial world (Asvial et al.
, 2021.
Suharini et , 2.
The development of blended learning, which is defined as hybrid learning, or known as a combination of conventional learning .
with online learning, is one of the best solutions in the learning conditions during the current pandemic so that the quality of education can improve.
(Batubara, 2021.
Syah, 2.
In order to prevent contracting COVID-19 and support the government in accelerating faceto-face learning, one way that can be done is to get used to washing hands with soap and running water, especially when in public places (Purnama & Susanna, 2.
Not only that, keeping a distance from friends and washing hands must be considered.
Based on the explanation of the problems that occurred during this pandemic, it is necessary to design automatic hand washing equipment technology, with the concept that people do not need to touch the water faucet to wash their hands so that minimizing the possibility of virus transmission is needed.
The design of this tool helps students in cultivating a clean life and also diligently washing their hands.
Presentation of tool components and demonstration of tools used at MTs Parmiyatu Wassa'adah.
RESEARCH METHOD
This research is focused on designing technological tools, namely hand washing equipment with a water and soap faucet design automatically and then demonstrating it for students at school to support blended learning.
The design of automatic hand washing technology tools and sensors is designed to be connected to each other so that the performance of the tool can work with good usage The technology component in the design uses a Photoelectric sensor using the principle of light reflection.
