EFFECTIVITY OF ETHANOLIC EXTRACTS FROM JAMBULANG FRUIT (SYZIGIUM CUMINI. L) AS ULTRAVIOLET ANTI RADIATION AGENT

This study aims to determine the effectiveness of ultraviolet anti-radiation agents on Jambulang ethanolic extract (Syzigium Cumini L) by calculating SPF,% T, and% Tp values in UV A and UV B wavelengths with concentration variation of 1 ppm, 10 ppm , 100 ppm and 1000 ppm. The preparation of jamblang fruit extract was done by maceration method using ethanol solvent. Measurement of absorbance value of the extract is by using UV-Vis spectrophotometer. The measurement result calculates SPF,% Te, and% Tp. The calculation results show the wavelength of UV A with concentration of 1 ppm, 10 ppm, 100 ppm, and 1000 ppm, where% Tp in the sunblock category has the value of 1.129; 1,126; 1,138; 1,142 and SPF with minimum protection category at concentration 1 ppm and 10 ppm has the value equal to 3,311 and 3,758, medium protection at concentration 100 ppm has the value equal to 4,989 and ultra protection at concentration 1000 ppm has the value equal to 315,5. UV B with% Te in the ultra-protection category has the value of 1.133; 1,158; 1,232; 2,731 and SPF with minimum protection category at concentration 1 ppm and 10 ppm has the value equal to 2,280 and 2,979, moderate protection at concentration 100 ppm has the value equal to 5,346 and ultra protection at concentration 1000 ppm has the value equal to 13002.
