Dry skin is the most common skin problem, so moisturizers are used to prevent it. White skin (mesocarp) of watermelon [Citrullus lanatus (Thunb.) Matsum. & Nakai] (MW) has the potential to be formulated into a moisturizing gel preparation since it contains vitamins and citrulline which also possess antioxidant activity. This study aimed to formulate a moisturizing gel preparation from MW extract as an antioxidant. MW was extracted by maceration using 70% ethanol and formulated into moisturizing gel preparation at concentrations of 5% (F1), 10% (F2), and 15% (F3). Gel preparations were evaluated physically, and determined their moisture content and antioxidant activity. MW extract was a brown color with 25.02% yield. The evaluation results showed that all formulations met the standard parameters of good gel preparations including organoleptic, homogeneity, spread-ability, adhesion, pH, and viscosity, and did not irritate the skin. The skin moisture after application of F1, F2, and F3 respectively were 29.49%; 36.63%; and 43.48%. IC50 values for F1, F2, and F3 respectively were 156.42; 149.24, and 138.05 µg/mL. The moisturizing gel preparation from MW extract met all the standard parameters of good gel preparation, could increase the percentage of skin moisture, and had moderate antioxidant activity.

UV exposure is the most significant environmental risk factor that can be altered for skin cancer andmany other skin conditions. An antioxidant is a compound that can protect the skin from sun radiation.Pandanus amaryllifolius is a plant that has antioxidant activity because it contains polyphenols. Theobjective of this study is to formulate a pandan Wangi leaf extract peel-off gel facial mask and analyzehow variations in the extract's concentration affect the physical and chemical evaluation. In this study,three formulas were made with varying concentrations of extract, namely F1 (1%), F2 (3%), and F3(5%). The preparation was evaluated for 28 days at a controlled room temperature (180C-300C+20C).The evaluation carried out included a physical evaluation (organoleptic, spreadability, homogeneity,viscosity, dry time) and a chemical evaluation (pH). The results showed that F1, F2, and F3 met therequirements for physical and chemical evaluation. Variations in the concentration of Pandan Wangileaf extract had a significant effect (p<0.05) on the results of the preparation evaluation which includedorganoleptic, spreadability, and viscosity. While for the evaluation of homogeneity, dry time, and pHdid not show significant results (p> 0.05). These results indicate that pandanus leaf extract (Pandanusamaryllifolius Roxb.) can be formulated into a peel-off gel facial mask.

Pedada fruit (Sonneratia caseolaris) contains phytochemicals such as steroids, tripenoids and flavonoids. Phytochemical compounds are antioxidants that neutralize free radicals that attack body cells. The application of making pedada fruit jam with the addition of carrageenan can function as a natural preservative. The purpose of this study was to determine the effect of adding carrageenan to the shelf life of pedada fruit jam. The research treatment consisted of 0 week of storage (P0), 1 week (P1), 2 weeks (P2), 3 weeks (P3), and 4 weeks (P4). Parameters observed in this study were the total plate count test, viscosity test, and antioxidant activity test with spektrofotometer Uv-Vis. The data obtained was tested with the ANOVA statistical test and continued with the DMRT test. The results of the research show that antioxidant activity and viscosity have decreasing values with each storage period, while microbiological activity is inversely proportional to antioxidant activity and viscosity, namely with increasing values with each storage period. The storage time for pedada fruit jam with the addition of carrageenan had a significant effect on antioxidant activity, viscosity and microbiological activity which had significantly different values (p < 0.05).
