Inovasi Teknologi Otomasi Hemat Air Wudhu (Media Wudhu Smart) Berbasis Microcontroller Penunjang Sustainable And Development Goals Clean Water And Sanitation

Abstract

Sustainable Development Goal (SDG) 6 emphasizes the importance of access to clean water and sanitation. Water-saving practices, especially in ablution activities, are important for maintaining the sustainability of water resources. This research aims to analyze the potential water savings in the use of ablution in the campus environment of Universitas Muhammadiyah Jember by using smart ablution media technology based on microcontroller. The research was conducted as a pilot project at Al-Qolam Mosque, with data collection on the volume of ablution water before and after the implementation of the automatic system. The system uses infrared sensors and the Arduino Nano microcontroller to control the water flow. The test results show that the use of an automatic ablution faucet reduces average water consumption by 0.7 liters or 20.6% compared to a regular faucet. The infrared sensor functions effectively in detecting the presence of objects and water level. This research shows that the application of smart ablution media technology can raise awareness of water conservation and contribute to efforts to achieve SDG 6. The use of this automatic system is expected to be more widely implemented to reduce water waste in various environments.
