PENENTUAN POTENSI TABIR SURYA EKSTRAK KLIKA ANAK DARA (Croton oblongus Burm F.)
Abstrak: A study concerning
the determination of the potential sunscreen extract cortex anak dara (Croton
oblongus Burm f.) UV-Vis spectrophotometry. This study aims to determine the
SPF value, percent transmission erythema (% Te), and the percent transmission
of pigmentation (% Tp) of the extract cortex anak dara (Croton oblongus Burm
f.) with use spectrophotometer UV-Vis. Determination of potential sunscreen SPF
value is determined based on the calculation of %Te and %Tp. The measurement
results indicate that the SPF value of the extract with a concentration of 300
ppm = 2,991. Value of %Te = 22, 655%, and the value of %Tp = 26.837%. SPF value
can be determined extract cortex anak dara (Croton oblongus Burm f.) at a
concentration of 300 ppm has a minimum level of protection and sunscreen for
the result value %Te and %Tp extract cortex anak dara (Croton oblongus Burm f.)
is said to not be able to hold the skin to prevent redness / erythema, but can
withstand pigmentation or darkening of the skin.
