Abstract
Biji Cokelat adalah buah yang sudah terkenal sejak zaman dahulu sebagai buah yang memiliki peranan penting dalam perindustrian bahkan kesehatan, salah satunya sebagai antibakteri. Biji cokelat mengandung senyawa tinggi akan flavonoid, tanin, dan alkaloid yang dapat memiliki efek antimikroba. Tujuan penelitian ini adalah untuk mengetahui efektivitas ekstrak biji cokelat terhadap bakteri Streptococcus pyogenes, yaitu dengan cara mengukur zona hambat menggunakan metode difusi Kirby-Beuer serial sumuran dengan konsentrasi ekstrak biji cokelat 20%, 40%, 60%, 80% dan 100%. Hasil penelitian menunjukan ekstrak biji cokelat dapat efektif memberikan efek antibakteri mulai dari konsentrasi terkecil 20% dengan rata-rata diameter zona hambat 8.07 mm sampai konsentrasi terbesar 100% dengan rata-rata diameter zona hambat 10.98 mm. Sedangkan rata-rata diameter zona hambat antibiotik Ampisilin sebagai kontrol (+) lebih besar dari konsentrasi ekstrak biji cokelat. Berdasarkan data tersebut dapat disimpulkan ekstrak biji kakao dapat efektif menghambat pertumbuhan bakteri Streptococcus pyogenes. Kata kunci : Ekstrak biji kakao, Streptococcus pyogenes, Uji antibaketr / Chocolate Seed is a fruit that has been famous since ancient times because this fruit has an important role in industry and even health, which is as an antibacterial. Chocolate seeds contain a high composition of flavonoids, tannins, and alkaloids which can have antimicrobial effects. The aim of this research was to study the effect of cocoa seed extracts against Streptococcus pyogenes, by measuring the inhibition zone using the Kirby-Beuer diffusion method c-plate technique using concentrations of cocoa extract 20%, 40%, 60%, 80% and 100%. The results showed that chocolate seed extract could effectively provide an antibacterial effect ranging from a concentration of 20% with an average diameter of inhibition zone of 8.07 mm to the largest concentration of 100% with an average zone diameter of inhibition of 10.98 mm. While the average diameter of the inhibitory zone of antibiotic ampicillin as a control (+) is greater than the concentration of cocoa seed extract. Based on these data, it can be concluded that cocoa seed extract can effectively inhibit the growth of Streptococcus pyogenes. Keywords : Cacao seed extract, Streptococcus pyogenes, Antibacterial
