Abstract
INDONESIA:
Kefir air merupakan salah satu minuman hasil dari fermentasi bibit kefir air. Media alternatif penting ditemukan untuk pengembangan produk ini, salah satu media yang berpotensi yaitu rebusan daun gaharu (Gyrinops versteegii). Penelitian ini bertujuan untuk mengetahui pengaruh lama fermentasi dan variasi konsentrasi terhadap karakteristik (total bakteri asam laktat, pH medium, kadar alkohol dan aktivitas antioksidan) kefir air rebusan daun gaharu (Gyrinops versteegii). Penelitian ini merupakan eksperimen dengan Rancangan Acak Lengkap (RAL) pola faktorial. Faktor I adalah konsentrasi rebusan daun gaharu (5%, 10%, 15% dan 20%). Faktor II adalah lama fermentasi (18 jam, 21 jam dan 24 jam ). dari kedua faktor tersebut di kombinasikan dengan penambahan sukrosa 6%, bibit kefir air 5% dan diinkubasi pada suhu ruang. Hasil penelitian menunjukan bahwa lama fermentasi dan variasi konsentrasi rebusan daun gaharu berpengaruh nyata terhadap semua parameter uji yaitu total BAL, pH medium, kadar alkohol dan aktivitas antioksidan dengan nilai signifikasi < 0,05.
Perlakuan S4M0 (Konsentrasi 20% dan Lama Fermentasi 24 jam) memberikan nilai terbaik pada uji aktivitas antioksidan. Hasil Penelitian total bakteri asam laktat, pH medium dan kadar alkohol telah memenuhi standard SNI. jumlah BAL (Bakteri Asam Laktat) setelah fermentasi berkisar 1 x 107 cfu/ml hingga 3,1 x 107 cfu/ml, derajat keasaman/pH medium setelah dilakukan fermentasi didapatkan nilai 4 – 3,27, kadar alkohol yang dihasilkan sesudah fermentasi berkisar 0,4 – 0,8 dan aktivitas antioksidan sangat kuat dengan nilai IC50 setelah fermentasi berkisar 23 – 3,89 (ppm). Berdasarkan data yang diperoleh, produk yang dihasilkan adalah produk yang halal dengan manfaat yang baik untuk kesehatan.
ENGLISH:
Kefir water is one of the drinks produced from fermented kefir seeds. An important alternative media is found for the development of this product, one of the potential media is the decoction of agarwood leaves (Gyrinops versteegii). This study aims to determine the effect of fermentation time and variations in concentration on characteristics (total Lactic Acid Bacteria, pH of medium, alcohol content and antioxidant activity) kefir boiled water of agarwood leaves (Gyrinops versteegii). This study was an experiment with a randomized block design (RAL) factorial pattern. The first factor is the concentration of agarwood leaf decoction (5%, 10%, 15% and 20%). Factor II is the duration of fermentation (18 hours, 21 hours and 24 hours). of these two factors combined with the addition of 6% sucrose, 5% kefir water seeds and incubated at room temperature. The results showed that the fermentation time and variations in the concentration of agarwood leaf stew had a significant effect on all test parameters, namely total BAL, chemical quality of medium pH and alcohol content) and antioxidant activity with a significance value <0.05.
The S4M0 treatment (20% concentration and 24-hour fermentation time) gave the best value in the antioxidant activity test. The results of the study were total lactic acid bacteria, pH of the medium and alcohol content that met the SNI standard. the amount of BAL (Lactic Acid Bacteria) after fermentation ranges from 1 x 107 cfu / ml to 3.1 x 107 cfu / ml, the acidity / pH of the medium after fermentation is 4 - 3.27, the alcohol content produced after fermentation ranges from 0 , 4 - 0.8 and antioxidant activity is very strong with IC50 values after fermentation ranging from 23 - 3.89 (ppm). Based on the data obtained, the products produced are halal products with good benefits for health.
