Strawberry is one of the most popular tropical fruits in Indonesia. The fruit has a concise shelf life and quickly deterioration after harvesting due to mechanical injury, physiological disorders, water loss, fungal growth, and high respiration rates. Postharvest technology is one technique that can maintain fruit quality and extend shelf life, one of which is a coating technique called edible coating. The edible coating layer of corn starch with the addition of curry leaf extract has antibacterial activity that can inhibit the growth rate of microorganisms. This study aimed to determine the characteristics of the edible coating solution produced from corn starch with the addition of curry leaf extract to produce the best edible coating layer. This study used a factorial completely randomized design experimental method, which consisted of treatment with curry leaf extract concentration (8%, 10%, and 12%) and dipping time (4, 5, and 6 minutes) with three repetitions. The result showed a significant delay in weight loss and total dissolved solids in strawberries compared to the uncoated control strawberries. In addition, the edible coatings had positive results in organoleptic based on panelists’ acceptance of color, aroma, taste, texture, and overall. These findings suggest that using 8% curry leaf extract with 4 minutes dipping time could be favorable to extend the shelf-life and maintain the quality of strawberry fruit.

Mimusops elengi L. fruit or known as Bakul fruit is believed to have a lot of benefit due to its flavonoid group compound that can have antioxidant effects. This study aimed to determine the effect of temperature and ratio between material and solvent in the extraction process on the antioxidant activity and content of phenolic compounds in Mimusops elengi L. fruit extract. This research used factorial completely randomized design with 2 factors : extraction temperature (45¼C, 60¼C, and 75¼C) and ratio of the material and solvent (1:4, 1:6, and 1:8) with 3 replications. The extraction yield, total phenolic contents and antioxidant activity of Mimusops elengi L. fruit extract were examined. Furthermore, the application of extraction temperature in 75¼C with ratio 1:8 material to solvent (w/v) has the highest extraction yield, total phenolic contents and antioxidant activity compared to others treatments.
