AKTIFITAS ANTIOKSIDAN SEDIAAN SCRUB TUBUH ALAMI KOMBINASI BUBUK KOPI (COFFEA ARABICA L) DAN RIMPANG KUNYIT (CURCUMA LONGA)

Abstrak

Tanaman kopi (Coffea arabica L) dan rimpang kunyit (Curcuma longa) diketahui memiliki kandungan asam klorogenat, dan kurkumin yang berkhasiat sebagai antioksidan. Antioksidan dapat melindungi kulit dari kerusakan oksidatif akibat paparan radikal bebas, serta memadamkan radikal bebas dan mengatasi peradangan melalui penghambatan pada sel kulit. Tujuan dari penelitian ini untuk mengetahui aktifitas antioksidan formulasi scrub tubuh alami kombinasi bubuk kopi dan rimpang kunyit. Simplisia Bubuk Kopi (Coffea arabica L) yang digunakan dalam penelitian ini sebanyak 20g sedangkankan simplisia rimpang kunyit (Curcuma longa) yang digunakan sebanyak 7g, kemudian kedua simplisia tersebut dikombinasikan menjadi sediaan scrub. Evaluasi mutu fisik berupa uji organoleptik, pH, daya lekat, viskositas, dan homogenitas. Penentuan aktivitas antioksidan dengan metode DPPH (1,1 – diphenyl – 2 – picryl – hydrazil). Scrub tubuh alami kombinasi bubuk kopi (Coffea arabica L) dan rimpang kunyit (Curcuma longa) berdasarkan hasil uji mutu fisik layak digunakan, kecuali hasil uji daya lekat dan homogenitas tidak layak digunakan. Sedangkan aktifitas antioksidan didapatkan hasil nilai IC50 sebesar 635,82 µg/mL dengan katagori sangat lemah. Berdasarkan hasil sediaan scrub tubuh alami kombinasi bubuk kopi (Coffea arabica L) dan rimpang kunyit (Curcuma longa) layak digunakan, meskipun memiliki aktivitas antioksidan yang sangat lemah.

Coffee plants (Coffea arabica L) and turmeric rhizomes (Curcuma longa) are known to contain chlorogenic acid and curcumin which are effective as antioxidants. Antioxidants can protect the skin from oxidative damage due to exposure to free radicals, as well as extinguish free radicals and overcome inflammation through inhibition of skin cells. The purpose of this study was to determine the antioxidant activity of a natural body scrub formulation combining coffee powder and turmeric rhizome.). The Coffee Powder Simplicia (Coffea arabica L) used in this study was 20g while the Turmeric Rhizome Simplicia (Curcuma longa) used was 7g, then the two simplicia were combined into a scrub preparation. Evaluation of physical quality in the form of Organoleptic Test, pH, adhesion, viscosity, and homogeneity. Determination of antioxidant activity by the DPPH method (1,1 - diphenyl - 2 - picryl - hydrazil). Natural body scrub combination of coffee powder (Coffea arabica L) and turmeric rhizome (Curcuma longa) based on the results of physical quality tests is suitable for use, except for the results of adhesion and homogeneity tests are not suitable for use. While the antioxidant activity obtained the IC50 value of 635.82 µg / mL with a very weak category. Based on the results of the natural body scrub preparation, a combination of coffee powder (Coffea arabica L) and turmeric rhizome (Curcuma longa) is suitable for use, although it has very weak antioxidant activity.
