Abstract
Kerusakan kulit akibat radikal bebas memicu stres oksidatif, sehingga dibutuhkan
antioksidan untuk melindungi sel kulit. Penelitian ini menyoroti peran antioksidan
dalam melindungi sel kulit dari kerusakan akibat radikal bebas yang memicu stres
oksidatif. Ketika antioksidan alami tubuh tidak cukup, diperlukan asupan tambahan
seperti biji pinang yang kaya akan alkaloid, flavonoid, dan tanin. Biji pinang dapat
diolah menjadi serum wajah berbasis liposom yang memiliki aktivitas antioksidan.
Ekstraksi menggunakan metode maserasi dengan pelarut etanol 96%. Ekstrak
etanol biji pinang menunjukkan aktivitas antioksidan sangat kuat dengan IC50
sebesar 2,3683 ± 0,002 ppm menggunakan metode DPPH dan kadar total flavonoid
72,7896 ± 0,48 mgQE/g. Formula liposom (kolesterol : lesitin = 1 : 10) optimal
mengandung 7,5% ekstrak etanol biji pinang dengan nilai %EE 93,3639 ± 0,0575%
menggunakan metode hidrasi lapis tipis dan partikel rata rata 435,770 nm, nilai IP
2,22 serta nilai zeta potensial rata rata -8,2 mV. Serum wajah dengan formula
terbaik adalah formula 3 yang mengandung 30% suspensi liposom ekstrak etanol
biji pinang dengan IC50 317,80 ± 0,039436 ppm. Analisis statistik melalui ANOVA
One Way menunjukkan perbedaan signifikan dalam aktivitas antioksidan formula
serum wajah dengan p-value < 0,05. Data evaluasi fisik dan aktivitas antioksidan
sebelum dan sesudah cycling test menunjukkan perbedaan signifikan melalui uji
paired t-test dengan p-value < 0,05. Sediaan ini rentan terhadap perubahan suhu
ekstrem, sehingga diperlukan uji stabilitas jangka panjang untuk mengevaluasi
kestabilannya selama penyimpanan dalam kondisi normal./Skin damage from free radicals triggers oxidative stress, necessitating antioxidants
to protect skin cells. This study highlights antioxidants' role in preventing such
damage. When natural antioxidants are insufficient, additional sources like areca
seed, rich in alkaloids, flavonoids, and tannins, are needed. Areca seed can be
formulated into a liposome-based facial serum with strong antioxidant activity.
Extraction uses maceration with 96% ethanol. The ethanolic areca seed extract
shows strong antioxidant activity (IC50 = 2.3683 ± 0.002 ppm, DPPH method) and
a total flavonoid content of 72.7896 ± 0.48 mgQE/g. The optimal liposome formula
(cholesterol: lecithin = 1:10) contains 7.5% extract, with an %EE of 93.36 ±
0.06%, an average particle size of 435.77 nm, an IP of 2.22, and a zeta potential of
-8.2 mV. The best serum formula (Formula 3) contains 30% liposomal extract
suspension, with IC50 = 317.80 ± 0.039 ppm. One-Way ANOVA reveals significant
differences in antioxidant activity (p < 0.05). Physical evaluation and antioxidant
activity tests before and after cycling indicate significant differences (paired t-test,
p < 0.05). This formulation is sensitive to extreme temperature changes, requiring
long-term stability testing under normal storage conditions.
