Abstract

Taro leaves (Colocasia esculenta L. Schoot) are widely used as vegetables and herbal medicines. In proving taro leaves as herbal medicine, taro leaves are changed in the form ofextract preparations. The choice of extraction method will affect the results of flavonoid levelsand antioxidant activity. Extraction methods that are widely used to extract taro leaves aremaceration and soxhletation. Maceration extraction method, the sample was immersed in 1000ml of ethanol and 1000 ml of n-hexane for 3 x 24 hours. Every 24 hours replaced with a newsolvent. Extracts were made by soxhletation method using ethanol as solvent and the other usingn-hexane as solvent. The material that has been submerged in petroleum ether is wrapped infilter paper and then tied with thread. Then it is put into the socket extractor. Furthermore, theflavonoid and antioxidant levels were tested. The highest flavonoid content in taro leaves wasobtained by maceration method with ethanol solvent, as much as 12.836 mg QE/g. The highestantioxidant activity was 91.812% by maceration method and n-hexane solvent. The macerationmethod with n-hexane solvent can obtain taro leaf extract which has high antioxidant activity.

Abstract

Cookies are high-energy and sugar snack that is popular in adolescents. Adolescents have a risk of infected anemia. One ingredient food that contains protein and iron which is good forpreventing anemia is Moringa oleifera L leaves. This study aims to determine the effect of addingMoringa leaves on sensory properties, protein, and iron levels in cookies. This research is usingthe True Experiment method with a Completely Randomized Design (CRD). The number ofvariations in the treatment in this study was P0=0 grams of moringa leaves, P1=5 grams, P2=10grams, P3=15 grams. Test for sensory properties using the hedonic test, the protein content testused the Kjedahl method and the iron test used the Spectrophotometric method. The statisticaltest of protein and iron levels used ANOVA. The results showed the best treatment is cookies withthe addition of 10 grams of Moringa leaves (P2). The highest protein content in P3 was 24.609%,and the lowest at P0 18.023% and showed significant differences between treatments. The highestof iron levels in P3 0.015%, and the lowest at P0 0.003% and showed significant differencesbetween treatments. The addition of moringa leaves to cookies affects sensory properties,increases levels of protein and iron.Keywords : Cookies, moringa leaves, protein, iron, sensory properties
