Abstract
Infark Miokard Akut (IMA) adalah suatu kondisi aliran darah
dan sirkulasi oksigen pada arteri tersumbat akibat plak aterosklerosis.
Pada tahun 2019 World Health Organization (WHO) menyebutkan
sebanyak 17,9 juta korban meninggal dunia akibat penyakit
kardiovaskuler seperti IMA. Salah satu tanaman yang berpotensi
sebagai penghasil enzim fibrinolitik adalah tanaman asam jawa. Tujuan
penelitian ini yaitu untuk mengetahui konsentrasi yang paling optimum
dari hasil uji SPSS ekstrak enzim buah asam jawa (Tamarindus indica
L.) sebagai agen fibrinolitik secara in vitro.
Metode penelitian meliputi identifikasi gen penyandi protease
serin dengan NCBI dan referensi jurnal, determinasi tanaman,
pengumpulan bahan, ekstraksi enzim dengan metode sentrifugasi,
pemurnian dengan menggunakan amonium sulfat 80%, pengukuran
kadar protein dengan metode Lowry, dan uji aktivitas fibrinolitik
dengan metode clot lysis secara in vitro yang dibuat dalam konsentrasi
bervariasi, antara lain 20%, 40%, dan 80%.
Kadar protein total pada ekstrak kasar enzim fibrinolitik buah
asam jawa (Tamarindus indica L.) supernatan sebelum pemurnian yaitu
147,7 µg/ml dan pada pelet sesudah pemurnian yaitu 290,3 µg/ml.
Pengaruh penambahan garam amonium sulfat 80% mengakibatkan
kadar protein total menjadi mengendap dan membuat peningkatan pada
aktivitas enzim buah asam jawa (Tamarindus indica L.) yang
disebabkan karena protein tersebut semakin murni. Konsentrasi yang
paling optimum dari hasil uji ekstrak enzim buah asam jawa
(Tamarindus indica L.) adalah pelet sesudah pemurnian dengan
konsentrasi 80% menunjukkan persentase lisis bekuan darah sebesar
65% yang berpotensi sebagai agen fibrinolitik secara in vitro.
Acute Myocardial Infarction (AMI) is a condition where blood
flow and oxygen circulation in the arteries are blocked due to
atherosclerotic plaque. In 2019, the World Health Organization (WHO)
stated that 17.9 million people died from cardiovascular diseases such
as AMI. One plant that has the potential to produce fibrinolytic
enzymes is the tamarind plant. The aim of this research is to determine
the most optimum concentration from the SPSS test results of the
enzyme extract of tamarind fruit (Tamarindus indica L.) as an in vitro
fibrinolytic agent.
Research methods include identification of genes encoding
serine proteases using NCBI and journal references, plant
determination, material collection, enzyme extraction using the
centrifugation method, purification using 80% ammonium sulfate,
measuring protein levels using the Lowry method, and testing
fibrinolytic activity using the clot lysis method. in vitro made in
varying concentrations, including 20%, 40% and 80%.
The total protein content in the crude fibrinolytic enzyme
extract of tamarind fruit (Tamarindus indica L.) supernatant before
purification was 147.7 µg/ml and in the pellet after purification it was
290.3 µg/ml. The effect of adding 80% ammonium sulfate salt causes
the total protein level to precipitate and causes an increase in the
enzyme activity of tamarind fruit (Tamarindus indica L.) which is
caused by the protein becoming more pure. The most optimum
concentration from the test results of the enzyme extract of tamarind
fruit (Tamarindus indica L.) is the pellet after purification with a
concentration of 80% showing a blood clot lysis percentage of 65%
which has the potential as a fibrinolytic agent in vitro.
