Abstract

Milk kefir is fermented milk produced by the activity of Lactic Acid Bacteria (LAB), yeast and acetic acid bacteria. Kefir milk contains many nutrients and properties, including immunomodulators, antibiotics, antioxidants and is rich in probiotics when compared to yogurt. Kefir milk from goats has more benefits than those from cow's milk, but it is still rarely in demand by the public because of its pungent aroma and taste. Star fruit is also known to have properties as an antibacterial, natural antioxidant and natural sucrose. Red ginger has also been widely recognized as a spice that has many properties as antibacterial, antioxidant, anti-inflammatory, and antiviral. In this study, researchers wanted to know the quality of the combination of Kefir milk with sweet star fruit juice and red ginger extract. The research will be carried out from February to May 2021. The kefir milk test includes bacteriological and physicochemical tests. The research design used a completely randomized design centered on one factor, namely the concentration of red ginger extract (0% control concentration, 4.5%, 6%, 7.5%). With Replica 3 times. Physicochemical tests are total acidity test, Vitamine c test and viscosity test. The results of the study showed that kefir fermented goat milk with the addition of star fruit juice and ginger juice was good for consumption, namely in treatment group 1 (containing 20% ​​star fruit juice and 4.5% red ginger juice).

Abstract

Tujuan penelitian ini adalah untuk mengetahui aktivitas antioksidan alga merah Porphyra ssp melalui uji fitokimia dan uji DPPH (1,1-diphenyl-2-picrylhidrazyl). Untuk proses ekstraksi penelitian ini menggunakan pelarut etanol dengan konsentrasi 70%. Analisis yang dilakukan meliputi rendemen, uji fitokimia, dan perhitungan IC50 dari masing-masing ekstrak. Nilai rendemen sebesar 1,8%. Hasil uji fitokimia menunjukkan bahwa sampel yang diekstrak dengan methanol 95% memiliki 6 komponen antioksidan yang diuji secara kualitatif (alkaloid, steroid, saponin, terpenoid, polifenol dan flavonoid). Nilai IC50 paling baik diperlihatkan oleh sampel yang diekstrak dengan etanol 70% yaitu sebesar 97,522 ppm. Secara keseluruhan penelitian ini memperlihatkan efektivitas sampel Porphyra ssp sebagai sumber antioksidan alami.
