PM I KKN team leader Putu Eka Widya Pratama SSi MSc RWTH says that aerators are essential to provide oxygen supplies to farmed shrimp as they develop. The lecturer, who also goes by Eka, explains that his team chose Gunung Anyar Tambak Village, Surabaya, to implement the innovation because it is developing its own shrimp farming industry and is expected to become a digital village by developing renewable energy.
