The Covid-19 pandemic has become a global disaster and not only in Indonesia. The whole world has been negatively affected by the presence of Covid-19, including almost all aspects that were quite affected by the presence of Covid-19. The incidence of the corona virus pandemic or covid-19 is able to paralyze the activities of all people who are carried out outside the home. Corona virus is a large family virus that causes mild to severe illness, such as the common cold or cold and serious illnesses such as MERS and SARS. Transmission from animals to humans (zoonosis) and transmission from humans to humans is very limited. The covid-19 pandemic cannot be controlled quickly so it requires proper management from both the government and the community. The covid-19 virus can easily be transmitted through droplets that come out well when talking, or through airborne droplets, so it doesn't take long for Covid-19 to spread. The spread is quite fast, especially in Indonesia. Various efforts have been encouraged by the government. Wearing a mask can prevent the spread of droplets, because droplets can be caught on the masks used, but droplets that stick to masks can also spread again if they are not handled correctly. The increase in the use of masks and gloves at the household level also needs special attention. Household medical waste has the potential to be mixed with other household waste, thus endangering garbage transport officers who generally work without PPE or use inadequate PPE. According to some estimates, globally, there are 129 billion face masks and 65 billion plastic gloves every month. Which of course will be dangerous if not handled properly and appropriately. Due to the problem, so the main focus is to design a Mask Shredder with Disinfectant Sprayer that will combine a mask destroyer and a disinfectant spray in it. So that the masks that have been used can be immediately destroyed and sprayed with disinfectants to prevent the spread of droplets. This machine modification process uses the reverse engineering method and the VDI 2221 method for the engineering design process.
