One standout project was PathoKit, a device designed to detect pathogenic bacteria in milk, ensuring its safety before consumption. The tool was developed by a team consisting of Nafa Lutfia Atihrah Chandra, Tjhan, Kevin Reagen Sugiarto, and Yohanes Ari Putra Pandapotan (Electrical Engineering, 2021).

PathoKit works by detecting milk samples dropped onto an electrode and then converting the resulting electrical signals into measurable concentrations of E. coli and Salmonella鈥攖wo common bacteria responsible for milk-related food poisoning.

Team member Reagen highlighted the tool's affordability compared to existing products on the market. 鈥淚t鈥檚 simple and practical to use, with an estimated testing time of only about 3 minutes,鈥� he said.

Reagen explained that the team was motivated to create PathoKit in response to growing concerns about food poisoning incidents linked to the Free Nutritious Meal (MBG) program, which were suspected to be caused by milk contaminated with harmful bacteria.

He emphasized that this device could help ensure the safety of milk sourced from local producers before it is distributed through the MBG program, thus reducing the risk of poisoning from unfit milk.

The team hopes their innovation will be particularly useful for primary and kindergarten school teachers, who could serve as the end users. 鈥淚 truly believe that this tool can be operated by non-experts, given its relatively simple mechanism,鈥� said Reagen.
