Abstract

This community service activity aims to develop superior products at Cipta Rasa Agrotourism, Palangkaraya, through the application of vacuum frying technology. The focus of the activity included selecting the right fruits, namely crystal guava and papaya, based on their low moisture content and ease of processing. Making sample chips from these two fruits resulted in a crispy, low-oil product, while maintaining natural flavors and nutrients. In addition, the selection of appropriate packaging materials, using a combination of aluminum foil and OPP plastic, provides optimal protection of product quality and extends shelf life. An attractive and informative packaging design was also prepared to increase the product's competitiveness in the market. The results of this activity show that vacuum frying technology and good packaging design can increase the added value of agro-tourism products, support the concept of green economy, and have a positive impact on the welfare of farmers and environmental sustainability. This chip product has great potential to be marketed widely, both at the local and national levels.

Abstract

Free radicals are molecules with unpaired electrons that are reactive and unstable. Gold nanoparticles (AuNPs) have an antioxidant reducing Au3+ to Au+ which can stabilize free radicals. This research aims to characterize AuNPs, formulate and evaluate AuNPs antiaging serum with sirih hutan leaves fraction and antioxidant activity test. The research method used was maceration, sirih hutan leaves were extracted using 96% ethanol, fractionation using n-hexane, biosynthesis of AuNPs, formulation, and antioxidant activity using the DPPH method. The data analysis used One Way Anova test and post hoc Tukey (CI 95%). The research results showed that ethanol extract and n-hexane fraction were obtained at 132.5059 g and 18.3804 g respectively. Biosynthesis characterization of AuNPs have a particle size of 424.9 nm. Formulation and evaluation of AuNPs formulation were generally obtained according to SNI. The antioxidant activity of the formulation and vitamin C showed that the percentage of DPPH increased with increasing concentration, IC50 values of the formulaion and vitamin C showed 35.21 ± 0.95; 17.95 ± 0.34 ppm respectively. Based on One Way Anova test, there was significant difference in each concentration in the percentage of DPPH (p<0.05). and the formulation and vitamin C were classified as very strong antioxidants (IC50<50).
