Abstract
The use of cosmetics for young people in the current era has become a trend in itself. Many cosmetic brand products on the market make people have to be literate about what content they contain. Generally, cosmetics with natural ingredients are the target of young people. Extraction of dragon fruit peel is an alternative to using waste to produce advanced materials in the field of natural cosmetics. The aims of this research is to determine the evaporation rate using a rotary evaporator by varying the amount of solvent and evaporation time in order to obtain the appropriate extract. The procedure of this research is by preparing the raw material used, namely dragon fruit peel waste. The dragon peel waste is cut with a size of 2-3 cm, mashed using copper until evenly distributed. Then the results of the dragon fruit peel that have been smooth are added with solvents using 70%, 60%, and 50% ethanol and 1% HCl for 24 hours with a certain ratio. After that it is filtered to get the maserate. Then the results of the macerate were put into the evaporator at a temperature of 80 - 90 oC for a certain time (10, 20, 30, and 40 minutes) and the rate of evaporation was observed. The results of the analysis will be used to determine the rate of evaporation and the quality of the dragon fruit peel extract obtained. From the evaporation results, the maximum evaporation rate was obtained at 40 minutes at a variation of 70% ethanol, which was 0.5 mL/minute. The dragon fruit peel’s antioxidant content was obtained by an average of 92% - 93%.
