Banana skin is often thrown away in any place. If discarded carelessly, a banana skin can make people slip. However, three students of Biology ITS, never underestimate a banana skin. Because after investigation proved a banana skin can not be considered trivial stuff.
"Banana skin that is often considered worthless goods, it was found to have vitamin C, B, calcium, protein, and fat is also sufficient," said Sulfahri, one of three researchers. Looking at the ingredient that is high enough, he and two colleagues tried to make a snack of banana skin material.
"Initially, we only manufacture chips banana peel, but eventually the idea arose to make flour from banana skin," he said. Students of 2007, said the banana flour was finally used as a raw material sponge cake. Despite repeatedly failed, but eventually they found the right formula to make the cake of a banana skin.
"If calculated more than 50 times, but we are now satisfied with the cake recipe that wehave," he said. Banana skin match made flour is a type of plantain, plantain skin is thicker than other types of bananas.
Sulfahri works and two colleagues was one of the innovative work that was selected in the screening for "Biological Opus Fair" held at the Plaza Dr. Figures ITS Surabaya.
