ABSTRAK
Aldila Wulan Yuniar 26060117140024. Aktivitas Antioksidan dan Mutu
Body Lotion dengan Variasi Konsentrasi Ekstrak Rumput Laut Ulva lactuca.
(Eko Nurcahya Dewi dan Ima Wijayanti)
U. lactuca mengandung senyawa fenolik yang terbukti memiliki aktivitas
sebagai antioksidan sehingga dapat diformulasikan dalam produk personal care
yaitu body lotion. Body lotion merupakan produk kosmetik yang terbuat dari 2 fase
yang berbeda, yaitu fase air dan minyak dan berfungsi sebagai pelindung kulit.
Tujuan penelitian untuk mengkaji pengaruh perbedaan konsentrasi ekstrak kasar U.
lactuca terhadap aktivitas antioksidan dan mutu terbaik body lotion. Metode
penelitian yang digunakan experimental laboratories dengan Rancangan Acak
Lengkap (RAL) satu faktorial perbedaan konsentrasi ekstrak U. lactuca yaitu
0%(K), 0,25%(X), 0,50%(Y) dan 0,75%(Z) dengan tiga kali ulangan. Parameter uji
yang dilakukan yaitu aktivitas antioksidan, pH, viskositas, stabilitas emulsi, iritasi
dan hedonik. Data parametrik dianalisis sidik ragam dan uji Beda Nyata Jujur
(BNJ), sedangkan data non parametrik dianalisis menggunakan Kruskal Wallis dan
Mann-Whitney. Penambahan konsentrasi ekstrak kasar U. lactuca meningkatkan
nilai aktivitas antioksidan dan viskositas body lotion, namun menurunkan nilai pH
dan hedonic serta tidak memiliki pengaruh yang berbeda pada uji stabilitas emulsi
dan iritasi . Perlakuan penambahan ekstrak kasar U. lactuca terbaik adalah
konsentrasi 0,50% dengan nilai aktivitas antioksidan inhibisinya 25,88±0,267%;
pH 5,4±0,100; viskositas 7000 cPs; stabilitas emulsi 100%; tidak menimbulkan
iritasi pada kulit dan hedonik dengan selang kepercayaan 4,78 < µ < 4,82.
Kata Kunci : Antioksidan, Body lotion, Konsentrasi Ekstrak, Mutu, Ulva lactuca.

ABSTRACT
Aldila Wulan Yuniar 26060117140024. Antioxidant Activity and Quality
Body Lotion with Various Concentrations of Ulva lactuca Seaweed Extract .
(Eko Nurcahya Dewi dan Ima Wijayanti)
U. lactuca contains phenolic compounds which are proven to have
antioxidant activity so that it can be formulated in personal care products, such as
body lotion. Body lotion is a cosmetic product that made from 2 different phases,
water and oil phases and it can be as a skin protector. The study aimed to examine
the effect of different concentrations of crude extract of U. lactuca on antioxidant
activity and the best quality of body lotion. The research method used was
experimental laboratories with a one factorial Completely Randomized Design
(CRD) with differences in concentrations of U. lactuca extract were 0%(K),
0.25%(A), 0.50%(B) and 0.75%(C) with three replications. The test parameters
performed were antioxidant activity, pH, viscosity, emulsion stability, irritation and
hedonic. Parametric data were analyzed by means of variance test (ANOVA) and
Honest Significant Difference (HSD) test, while non-parametric data were analyzed
using Kruskal Wallis and Mann-Whitney. The addition of U. lactuca crude extract
concentration increased the value of antioxidant activity and body lotion viscosity,
but decreased the pH and hedonic values and had no different effect on emulsion
stability and irritation tests. The best treatment for the addition of crude extract of
U. lactuca was a concentration of 0.50% with an inhibitory antioxidant activity
value of 25.88 ± 0.267%; pH 5.4±0.100; viscosity 7000 cPs; emulsion stability
100%; didn’t irritate the skin and have hedonic value with a confidence interval of
4.78 < µ < 4.82.
