Abstract

Ekstrak etanol kulit kopi arabika (Coffea arabica L.) memiliki aktivitas antioksidan dan sun protection. Tujuan penelitian ini adalah untuk mengetahui aktivitas antioksidan, kadar fenol total, dan nilai sun protection factor (SPF) fraksi dari ektrak etanol kulit kopi arabika. Fraksinasi menggunakan metode fraksinasi cair-cair menggunakan pelarut n-heksana, etil asetat dan air. Penetapan kadar fenol total, aktivitas antioksidan dan nilai Sun Protection Factor (SPF) dilakukan secara spektrofotometri UV-Vis. Hasil penelitian ini, fraksi air kulit kopi arabika memiliki IC50 terhadap DPPH sebesar 23, 719 bpj, kadar fenol total sebesar 8,308 g GAE/100 g, serta nilai SPF sebesar 23,5 pada konsentrasi 500 bpj. Berdasarkan hasil penelitian, fraksi air dari ekstrak etanol kulit arabika lebih berpotensi ditinjau dari aktivitas antioksidan serta nilai sun protection factor daripada fraksi etil asetat dan fraksi n-heksana. --- Arabica coffee skin ethanol extract (Coffea arabica L.) has antioxidant and sun protection activity. The purpose of this study was to determine the antioxidant activity, total phenol content, and sun protection factor (SPF) fraction value of arabica coffee skin ethanol extract. Fractionation using liquid-liquid fractionation method using n-hexane solvent, ethyl acetate and water. Determination of total phenol levels, antioxidant activity and Sun Protection Factor (SPF) values was carried out by UV-Vis spectrophotometry. The results of this study, the Arabica coffee skin water fraction has IC50 against DPPH of 23.719 ppm, total phenol content of 8.308 g GAE / 100 g, and SPF value of 23.5 at a concentration of 500 ppm. Based on the results of the study, the water fraction of arabica skin ethanol extract is more potential in terms of antioxidant activity and sun protection factor value than ethyl acetate fraction and n-hexane fraction.
