UNS – Environmental pollution is one of the impacts caused by the rapid growth of industrialization that does not only occur in big cities, but also comes to the rural areas. Methylene Blue or MB is one of the most widely used dyes as base color and it also has good solubility. In the industrial process, the use of methylene blue is only about 5% while the 95% remaining is wasted.
Based on that phenomenon, three students of Faculty of Mathematics and Natural Sciences Universitas Sebelas Maret (FMIPA UNS) Surakarta, namely Syahna Febrianastuti (2014), Elsa Ninda Karlinda Putri (2014), and Uly Wulan Apriani (2015) created synthesis and application biomaterials of methylene blue dye absorption by eco-bio technique (electrochemical adsorption).
They implemented new technologies that are environmentally friendly, inexpensive, and effective to reduce pollution levels called BIA-GOAL (Bioadsorben Graphene Oxide-Alginate). BIA-GOAL uses alginate material that can be obtained from seaweed. The observation results showed a decrease in methylene blue content by 90.37%.
This innovation product is expected to reduce pollution to the ecosystem and to prevent diseases such as heart rate increasing disease and vomiting. humas-red.uns.ac.id/Tni/Dty
