Ethyl acetate is a clear, colorless, smelling typical liquid which commonly used as a flavor enhancer. Banana peels contain high valuable components, such as carbohydrates, vitamin C, calcium and other nutrients. The purpose of this study was to utilize the ‘raja’ banana peel waste (Musa paradisiaca L.) in the making of ethyl acetate. Variation in this experiment were comparison of raw materials and water 1: 2; 1: 4; 1:6; 1: 8 and hydrolysis time’s of 60 minutes, 90 minutes, 120 minutes and 180 minutes. At first banana peel was scraped. Than was hydrolyzed with water for 70°C using acid hydrocloric acid as catalist. The hydrolysis product was fermented for 24 hours using instant yeast 'Fermipan' and then was distilled. The Distillation product was esterified with acetic acid and hydrochloric acid as catalyst for 70 minutes at 76°C. The influence of various process variables were observed in this experiment. The maximum ethyl acetate was obtained 12 ml with concentration of 68,58%. at condition of raw materials and water ratio 1:6 and hydrolysis time of 120 minutes. The results obtained in this experiment showed that the ‘raja’ banana peel can be used as an alternative raw material which low cost and easy to obtain to produce ethyl acetate.
