UNY Students Turn Water Hyacinth into Natural Food Sanitizer
What once clogged local waterways is now a promising solution for cleaner, safer food. A group of students from Universitas Negeri Yogyakarta (UNY) has created SteriLiz, a natural antibacterial spray made from water hyacinth, a plant often considered a nuisance. This innovation was born from both environmental concern and a growing awareness of food hygiene.
