Mersing Polytechnic invents mobile incubator to detect bacteria in water

Chief researcher Siti Farah Hussin said the initiative was triggered when it was found that microbiologists often face issues to test water samples in water sources.

She said the traditional method of conducting tests on water samples is usually done in a laboratory, taking a long time of about 18 to 24 hours, besides demanding more frequent observations to look out for bacterial growth.

"This incubator can be used in a direct current (DC) connection, by using a battery source that can last up to two days (48 hours), or even through a regular plug to identify the presence of E.coli and Coliform bacteria that can be done anywhere.

"Through a study conducted with the Ranhill SAJ Sri Gading central laboratory, Batu Pahat, this incubator was able to identify the presence of E.coli and Coliform bacteria in just six hours," said the lecturer from the polytechnic's Information and Communication Technology Department in an interview with Bernama here recently.

Elaborating further, Siti Farah said the incubator uses image processing technology and the internet of things which are both important elements in the Industrial Revolution 4.0. She said the incubator was also connected to a smartphone equipped with QR Water software.

QR Water also uses "two-factor authentication" technology, which only users registered in the database can use the QR Water incubator and software.

Siti Farah said the research was recognised not only locally but also abroad. A research paper entitled "Detection of Escherichia Coli Bacteria: A Review of Image Processing Method' was also published in the International Journal of Software Engineering and Computer Systems.

"This research paper was also presented at "The 4th International Conference on Research in TVET Studies" which took place at Pamulang University, Indonesia.
