Abstract
Aktivitas fibrinolitik merupakan proses pemecahan fibrin yang
berperan penting dalam mencegah dan mengatasi pembentukan bekuan
darah berlebih. Tempe gembus, hasil fermentasi dari sisa pembuatan
tahu oleh mikroorganisme Rhizopus sp., diketahui mengandung senyawa
bioaktif yang berpotensi sebagai agen fibrinolitik alami. Penelitian ini
bertujuan untuk mengetahui kadar protein ekstrak enzim tempe gembus,
menguji potensi aktivitas fibrinolitiknya, serta menentukan konsentrasi
optimum dalam melisiskan bekuan darah secara in vitro menggunakan
metode clot lysis.
Proses ekstraksi dilakukan dengan menggunakan buffer fosfat,
dilanjutkan dengan pemurnian menggunakan ammonium sulfat 80%.
Kadar protein diukur menggunakan metode Lowry, sedangkan aktivitas
fibrinolitik diuji dengan variasi konsentrasi 15%, 25%, 50%, dan 100%
pada sampel sebelum dan sesudah pemurnian. Nattokinase digunakan
sebagai kontrol positif dan buffer fosfat sebagai kontrol negatif. Data
dianalisis menggunakan ANOVA pada aplikasi SPSS.
Kadar protein dalam ekstrak enzim tempe gembus melalui metode
Lowry pada sampel sebelum pemurnian diperoleh 40,02µg/mL dan setelah
pemurnian diperoleh 104,27 µg/mL. Ekstrak enzim tempe gembus memiliki
aktivitas fibrinolitik dibuktikan dengan kemampuan ekstrak melisiskan
darah. Konsentrasi optimum dari uji ekstrak enzim tempe gembus adalah
sampel setelah pemurnian dengan konsentrasi 100% menunjukan
persentase lisis bekuan darah sebesar 57% yang berpotensi sebagai obat
fibrinolitik secara in vitro.
Fibrinolytic activity is a process of breaking down fibrin which
plays an important role in preventing and overcoming the formation of
excess blood clots. Tempeh gembus, the result of fermentation from the
rest of tofu making by the microorganism Rhizopus sp., is known to
contain bioactive compounds that have the potential to be natural
fibrinolytic agents. This study aims to determine the protein content of
tempeh gembus enzyme extract, test its potential fibrinolytic activity,
and determine the optimal concentration in lysizing blood clots in vitro
using the clot lysis method.
The extraction process is carried out using phosphate buffers,
followed by purification using 80% ammonium sulfate. Protein levels
were measured using the Lowry method, while fibrinolytic activity was
tested with concentration variations of 15%, 25%, 50%, and 100% in
samples before and after purification. Nattokinase is used as a positive
control and a phosphate buffer as a negative control. Data were analyzed
using ANOVA on the SPSS application.
The protein content in the enzyme extract of tempeh gembu through
the Lowry method in samples before purification was obtained at
40.02μg/mL and after purification was obtained at 104.27 μg/mL. Tempeh
gembus enzyme extract has fibrinolytic activity as evidenced by the extract's
ability to lyze the blood. The optimum concentration of the tempeh gembus
enzyme extract test was a sample after purification with a concentration of
100% showing a blood clot lysis percentage of 57% which has the potential
to be a fibrinolytic drug in vitro
