Abstract

Human life today is faced with various types of obstacles parallel with the development of mainstream technology. Year 2019 saw a huge wave of obstacles resulting in changes in many aspects especially health. Corona virus 2019 (COVID-19) was discovered for the first time in the world. The virus is believed to have originated from a small town in China, Wuhan. Most frighteningly, many experienced scholars and doctors have done research to find the cure but failed. Until now, this virus still has no cure. The virus has claimed millions of lives and has scarred the hearts of many people so much that many countries have declared a state of emergency and movement control orders. Therefore, the authorities have made various initiatives to control the spread of this virus such as holding a Standard Operation Procedure (SOP) for example, social distancing, wearing face masks and wearing disinfectant fluids such as hand sanitizer regularly. Even so, this COVID-19 is still alive with us till this day. Precautions still need to be taken. Therefore, this project is an initiative to help us avoid this killer virus. The project applies light technology that has been proven effective to kill bacteria especially in hospitals as well as kill viruses in water and air. UV rays can be applied to 3 types, namely UV-A, UV-B, UV-C. The difference between these lights is their wavelength in nanometres. The most effective wavelengths for this eradication process are lOOnm up to 280nm. In addition, this project uses renewable energy that is sourced from solar. In conclusion, in line with the currents of modernity we always have ways to avoid these symptoms of CO VID-19. As the saying goes, "prevention is better than cure".
