The part that is rarely used from all parts of a banana plant is a banana weevil. At present the use of banana weevil is still very limited, for example it is only used as chips. However, a study conducted by Lina Agustina, a student from the University of Muhammadiyah Surakarta (UMS), in 2008, tried to do a study using banana weevil to be made into alcohol vinegar by fermentation.

She described fermentation as anaerobic dissimilation of organic compounds caused by microorganism activity. Because the wet banana weevil contains 11.6 g of carbohydrates and the dried banana weevil contains 66.2 g of carbohydrates, so that it can be used as a raw material in the manufacture of vinegar through the fermentation process. This can be used as one way to meet the growing needs of vinegar, where vinegar is needed by industries that are food, laboratory (chemistry, biology), pharmaceutical factories and so on.
