Touchless Smart Toilet

Telkom University students created a smart toilet innovation that can provide an early detection system and can provide user health information based on feces and urine detection results equipped with tips so that users can immediately take action to prevent or reduce the impact of disease in the future. The Touchless Smart Toilet was created by students of the 2019 Faculty of Electrical Engineering (FTE), namely Luthfi Noor SZ as an Android Developer; Rafli AP as a Hardware Engineer; Putri Nurani as a Cloud Developer; and Shafira Amkha Z as a Machine Learning Engineer. The four students, during their research were guided by FTE Lecturer, Edward ST, MT.

This Touchless Smart Toilet was developed through Telkom University's Student Creativity Program for Creative Ideas (PKM-KC) and received funding from the Ministry of Education, Culture, Research, and Technology. Rafli, a Hardware Engineer, explained that this toilet aims to make it easier for users to monitor their health continuously or daily. "Users can monitor their health from home using their mobile phones.

"Users don't need to bring their phones into the toilet to operate it. However, the smart toilet will still provide information about the condition of their feces and urine as long as the toilet and the app on the user's phone are connected to the internet," explained Rafli.

Touchless Smart Toilet is an Internet of Things (IoT)-based smart toilet that can detect and predict user health based on feces and urine conditions through feces shape and color recognition, as well as urine color using computer vision (CV) and deep learning (DL) technology integrated with the application.

Another feature of the Touchless Smart Toilet is the gesture and touchless control feature to reduce the spread of germs or viruses from the user's hands.

This feature also makes it easier for users to operate the toilet. The IoT implementation in this toilet allows users to receive detection data directly to their smartphones, thereby maintaining a regular health record.

Additionally, the touchless system's hardware components and detection camera are housed in a sealed enclosure, ensuring they are safe from short circuits. Converting from a regular toilet to a Touchless Smart Toilet is time- and cost-effective, as the device is easily assembled and disassembled (modular).

“"To reduce the risk of spreading bacteria and viruses, we've integrated an ultrasonic sensor to flush feces or urine. Users don't need to press the toilet flush button; they simply place their hand over the ultrasonic sensor. The system then activates and performs an automatic flush and analyzes the urine and feces," said Shafira, Machine Learning Engineer.

Putri, a Cloud Developer on the team, said another advantage of the Touchless Smart Toilet is its health advice feature. This feature is designed to help users actively respond to health monitoring. Users will be referred to a doctor or hospital if the system detects they are unwell.

The Touchless Smart Toilet is a new breakthrough developed as a tool to support medical check-ups in clinics, laboratories, and hospitals. This was revealed by Luthfi, the Android developer behind this innovation.
“"In the future, the Touchless Smart Toilet could become a healthcare tool that can help improve the well-being of its users and can be integrated with hospitals for health monitoring. We also hope that with the realization of the PKM-KC, the Touchless Smart Toilet will be useful and facilitate users in monitoring their daily health," Luthfi concluded.
