Abstract
Bunga telang (Clitoria ternatea L.) mengandung senyawa metabolit sekunder, terutama fenolik, flavonoid dan antosianin, yang berpotensi sebagai antioksidan dan tabir surya alami. Penelitian ini bertujuan mengetahui aktivitas antioksidan dan nilai Sun Protection Factor(SPF) ekstrak etanol bunga telang serta sediaan masker gel yang mengandung ekstrak tersebut. Penelitian meliputi determinasi tanaman, ekstraksi dengan metode maserasi menggunakan etanol 70%, karakterisasi simplisia dan ekstrak, serta penapisan fitokimia. Aktivitas antioksidan ditentukan menggunakan metode DPPH berdasarkan nilai IC₅₀, sedangkan nilai SPF ditentukan secara spektrofotometri UV-Vis menggunakan metode Mansur. Ekstrak diformulasikan menjadi masker gel dengan konsentrasi 0,08%, 0,09%, dan 0,10%, kemudian dievaluasi meliputi organoleptik, homogenitas, pH, viskositas, daya sebar, dan daya lekat. Hasil penapisan fitokimia menunjukkan ekstrak mengandung alkaloid, flavonoid, fenol, tanin, saponin, triterpenoid, serta monoterpen dan seskuiterpen. Nilai IC₅₀ ekstrak sebesar 141,95 ppm, formula 1 sebesar 344,49 ppm, formula 2 sebesar 323,87 ppm, dan formula 3 sebesar 187,99 ppm. Nilai SPF ekstrak pada konsentrasi 800 ppm sebesar 14,829, 900 ppm sebesar 16,630, dan 1000 ppm sebesar 16,895. Nilai SPF formula 1 sebesar 14,779, formula 2 sebesar 16,002, dan formula 3 sebesar 16,262. Hasil penelitian menunjukkan formula 3 memiliki aktivitas antioksidan terbaik dan nilai SPF tertinggi dibandingkan formula 1 dan formula 2. ------ Butterfly pea flower (Clitoria ternatea L.) contains various secondary metabolites, particularly phenolic compounds, flavonoids and anthocyanins which have potential as antioxidants and natural sunscreen agents. This study aimed to determine the antioxidant activity and Sun Protection Factor (SPF) value of butterfly pea flower ethanol extract and gel mask preparations containing the extract. The study included plant identification, extraction using the maceration method with 70% ethanol, characterization of the crude drug and extract, and phytochemical screening. Antioxidant activity was determined using the DPPH method based on the IC₅₀ value, while the SPF value was determined using UV-Vis spectrophotometry with the Mansur method. The extract was formulated into gel masks at concentrations of 0.08%, 0.09%, and 0.10%, followed by evaluation of organoleptic properties, homogeneity, pH, viscosity, spreadability, and adhesion. Phytochemical screening showed that the extract contained alkaloids, flavonoids, phenols, tannins, saponins, triterpenoids, as well as monoterpenes and sesquiterpenes. The IC₅₀ value of the extract was 141.95 ppm, while Formula 1 was 344.49 ppm, Formula 2 was 323.87 ppm, and Formula 3 was 187.99 ppm. The SPF values of the extract at concentrations of 800 ppm, 900 ppm, and 1000 ppm were 14.829, 16.630, and 16.895, respectively. The SPF values of Formula 1, Formula 2, and Formula 3 were 14.779, 16.002, and 16.262, respectively. The results showed that formula 3 exhibited the highest antioxidant activity and the highest SPF value compared with Formulas 1 and 2
