Indonesia merupakan negara beriklim tropis dimana sangat memungkinkan kulit untuk terus terpapar sinar matahari. Radikal bebas berupa sinar ultraviolet dari matahari yang berlebih akan menyebabkan kerusakan pada kulit. Penggunaan lotion yang mengandung antioksidan dapat dilakukan untuk melindungi kulit dari paparan radikal bebas. Daun jambu air (Syzygium aqueum) merupakan salah satu tumbuhan yang memiliki aktivitas antioksidan. Senyawa myricetin dalam tanaman jambu air memiliki aktivitas sebagai UV protektor. Daun jambu air diekstraksi menggunakan pelarut etanol 96% dengan metode maserasi. Pengujian aktivitas antioksidan dilakukan menggunakan metode DPPH dengan vitamin C sebagai pembanding. Pengujian nilai SPF dilakukan menggunakan spektrofotometri UV-Vis yang didasarkan pada persamaan Mansur. Lotion Ekstrak etanol daun jambu air dilakukan pengujian aktivitas antioksidan, nilai SPF dan evaluasi organoleptik, homogenitas, pH, daya sebar dan daya lekat selama 4 minggu.  Hasil menunjukkan bahwa Ekstrak dan sediaan lotion ekstrak etanol daun jambu air (Syzygium aqueum) memiliki aktivitas antioksidan sangat kuat dan sedang, sedangkan nilai SPF-nya  termasuk kedalam kategori proteksi ultra dan maksimal.

Sunlight contains UV rays that adversely affect the skin. These adverse effects can be minimized by the use of UV protective materials, both natural and synthetic. Soursop fruit (Annona muricata L.) has a high content of polyphenol compounds, some vitamins such as vitamin C, B1 and B2. This study aims to determine the activity of UV light protection on soursop juice (Annona muricata L.) by using Sun Protection Factor (SPF) calculation. The measurement of SPF values using the UV-Vis spectrophotometric method in the wavelength range from 290-320 nm. The results showed that soursop juice (Annona muricata L.) had UV light protection activity at 1% concentration of 5,188, 3% concentration of 12.242 and 5% concentration of 17,247. The category of SPF values in a row that is medium, maximum and ultra

Abstract-Acute and chronic exposure to nonphysiological doses of ultraviolet radiation leads to variety of changes of skin ranging from sun-burn, erythema to skin cancer. For skin protection from deleterious effects of sunlight, sunscreen products are used in various forms having chemical and physical filters. However, synthetic sunscreen formulations are reported to cause adverse effects. Thus the present study was planned to evaluate the sun protection factor (SPF) of leaves extract of Murraya koenigii for their application as herbal sunscreens. The results suggested that the occurrence of active compounds responsible for ultraviolet absorption can be extracted for use in sunscreens preparations as better, cheaper and safe alternative to harmful chemical sunscreens. Keywords: UV radiations, SPF, Murraya koenigii

Research on the combination of natural ingredients from brown seaweed and Moringa, to be used as sunscreen has been nothing. Therefore, the objective of this study was to determine the best formulation from sunscreen evaluation. In this study, the ratio of Moringa oleifera and Turbinaria conoides was 1:1 (cream L), 2:1 (cream M), 1:2 (cream N), and control (no added both of natural ingredients) (cream K). The evaluation of sunscreen cream by Sun Protection Factor (SPF) activity, viscosity, pH, homogeneity, and microbial test. SPF values in this study from cream K, L, M, and N were 0.75±2.31, 17.80±0.97, 9.48±1.41, and 15.97±2.38, respectively. Viscosity values were 22,400 cPs for cream K; 32,400 cPs for cream L; 26,000 cPs for cream M; and 32,800 cPs for cream N. The pH value of sunscreen cream in cream K, L, M, N were 7.30±0.02, 6.51±0.02, 6.38±0.04, and 6.43±0.04, respectively. In all of the treatments of sunscreen cream, microbial tests are absent and have good homogeneity. The ratio of 1:1 (cream L) between M. oleifera and T. conoides has a good synergistic effect to ward off UV B light, therefore cream L is the best sunscreen cream in this study.
