Abstract

Kokang (Lepisanthes amoena (Hassk.) Leenh) and kersen (Muntingia calabura L.) are natural ingredients that have high antioxidant activity and are efficacious for various skin problems, one of which is as a natural sunscreen. The aim of this research is to formulate a combination of ethanol extracts of kokang leaves and kersen leaves in the form of a sunscreen cream that is physically stable and has sunscreen activity. The research method begins with the extraction of cockerel leaves and cherry leaves by maceration. Then the sunscreen activity of a combination of cock and cherry leaf extracts was tested using the spectrophotometric method.The formulation of the cream preparation was made in 3 different concentration variations of kokang and kersen leaf extract, namely F1 (0.05%: 0.1%), F2 (0.1%: 0.2%), and F3 (0.2 %:0.4%). Then the physical evaluation of the cream preparation was tested using the Freeze-Thaw method for 4 cycles and an irritation test. Then the sunscreen activity of the cream preparation was tested. The research results showed that the combination of kokang and kersen leaf extract had sunscreen activity with %Te and %Tp values of 0.2783 and

%Tp 9.2240 which were included in the sunblock category and SPF 24.43 in the ultra protection category. The three preparations are physically stable and have the best sunscreen activity in F3 with a %Te value of

0.24 and a %Tp of 6.1 in the sunblock category and SPF 25.54 in the ultra protection category.
