Abstract
Indonesian
Kappaphycus alvarezii merupakan salah satu jenis rumput laut merah (Rhodophyta) yang mengandung pigmen fikobiliprotein. Rumput laut merah didominasi oleh fikobiliprotein berjenis fikoeritrin. Tujuan dari penelitian ini adalah menentukan pengaruh jenis pelarut dan waktu akselerasi ekstraksi ultrasonikasi terhadap pigmen fikoeritrin. Proses ekstraksi dilakukan secara bertahap menggunakan pelarut akuades, CaCl2 dan buffer fosfat dengan akselerasi ultrasonikasi 35-55 menit. Hasil menunjukkan bahwa ekstrak pigmen fikoeritrin K. alvarezii menggunakan akuades menghasilkan warna pigmen lebih pekat dibanding buffer fosfat dan CaCl2, menunjukkan konsentrasi tertinggi sebesar 0,057 mg/mL, dan indeks kemurnian sebesar 0,189. Pelarut air aman digunakan karena air tidak memiliki daya toksik. Maka, tidak perlu dilakukan uji pendahuluan toksisitas pelarut. Lebih ekonomis dibandingkan dengan jenis pelarut lainnya. Ekstraksi pigmen fikoeritrin menggunakan pelarut akuades selama 45 menit menghasilkan warna pigmen lebih pekat. Konsentrasi pigmen fikoeritrin sebelum dan sesudah presipitasi berturut-turut sebesar 0,170 mg/mL dan 0,421 mg/mL. Indeks kemurnian pigmen fikoeritrin sebelum dan sesudah presipitasi berturut-turut sebesar 0,301 dan 0,831. Aktivitas antioksidan (% Inhibisi) terbaik ada pada konsentrasi pigmen fikoeritrin 50 ppm dan 80 ppm dengan lama waktu ekstraksi 45 menit berturut-turut sebesar 62% dan 89%. Profil protein dengan SDS-Page menunjukkan fikoeritrin memiliki bobot molekul 16,27 kDa pada subunit α, 17,79 kDa pada subunit β, dan 30,60 kDa pada subunit γ.

Kappaphycus alvarezii is a type of red seaweed (Rhodophyta) which contains phycobiliprotein pigments. Red seaweed is dominated by phycoerythrin type phycobiliprotein. Phycoerythrin can be obtained from the extraction process. The purpose of this study was to determine the effect of solvent type and acceleration time of ultrasonication extraction on phycoerythrin pigments. The extraction process was carried out in stages using distilled water, CaCl2 and phosphate buffer with ultrasonication acceleration of 35-55 minutes. The results showed that the phycoerythrin pigment extract of K. alvarezii using distilled water produced a more concentrated pigment color than buffer phosphate and CaCl2, showing the highest concentration of 0.057 mg/mL, and a purity index of 0.189. Water solvent is safe to use because water does not have toxic power. So, there is no need to conduct a preliminary test for solvent toxicity. It is more economical than other types of solvents. The extraction of phycoerythrin pigment using distilled water for 45 minutes resulted in a more concentrated pigment color. The concentration of phycoerythrin pigment before and after precipitation was 0.170 mg/mL and 0.421 mg/mL, respectively. The phycoerythrin pigment purity index before and after precipitation was 0.301 and 0.831, respectively. The best antioxidant activity (% inhibition) was found at concentrations of 50 ppm and 80 ppm phycoerythrin pigment with extraction time of 45 minutes at 62% and 89% respectively. Protein profile using SDS-Page showed that phycoerythrin has a molecular weight of 16.27 kDa in the subunit, 17.79 kDa in the subunit β, and 30.60 kDa in the subunit γ.
