ABSTRACT Banana is a climacteric fruit which has an advance rate of respiration. The respiration of the banana can be inhibited by deactivated the ethylene using potassium permanganate (KMnO4) with clay as a carrier. The use of clay mixed with KMnO4 as ethylene absorbent were able to maintain weight loss, respiration rate, total dissolved solids, total acid titrated, and color of kepok banana.…
