Abstract

Bunga telang merupakan tanaman yang dikenal memiliki kandungan senyawa aktif seperti flavonoid, alkaloid, tanin, dan saponin yang berpotensi sebagai antibakteri. Salmonella typhi adalah bakteri penyebab demam tifoid yang dapat menimbulkan masalah kesehatan serius, terutama di negara berkembang. Penelitian ini bertujuan untuk mengetahui aktivitas antibakteri dari ekstrak bunga telang (Clitoria ternatea L.) yang diperoleh dengan metode maserasi bertingkat menggunakan pelarut n-heksan dan etanol 70%. Serbuk bunga telang diekstraksi menggunakan metode maserasi bertingkat, diawali dengan n-heksan, kemudian etanol 70%. Ekstrak kental yang diperoleh diuji fitokimia dan diuji aktivitas antibakterinya terhadap Salmonella typhi menggunakan metode difusi sumuran. Konsentrasi yang digunakan yaitu 50% dan 100%, dengan kontrol negatif DMSO 10% dan kontrol positif kloramfenikol 5%. Hasil penelitian menunjukkan bahwa ekstrak bunga telang mengandung senyawa flavonoid, alkaloid, tanin, dan saponin yang memiliki aktivitas antibakteri terhadap Salmonella typhi. Ekstrak etanol 70% pada konsentrasi 100% memberikan diameter hambat paling besar yaitu 18,4 mm, diikuti oleh konsentrasi 50% sebesar 14,4 mm. Sementara itu, ekstrak n-heksan memberikan diameter hambat lebih kecil. Kontrol positif kloramfenikol 5% menghasilkan zona hambat 19,0 mm dan kontrol negatif DMSO tidak menunjukkan aktivitas hambat. Hasil analisis statistik menggunakan uji One Way ANOVA menunjukkan adanya perbedaan yang signifikan antara kelompok perlakuan (p = 0,000), yang menegaskan bahwa jenis pelarut dan konsentrasi ekstrak mempengaruhi aktivitas antibakteri. Butterfly pea (Clitoria ternatea L.) is a plant known to contain active compounds such as flavonoids, alkaloids, tannins, and saponins that are potential antibacterial agents. Salmonella typhi is the bacterium responsible for typhoid fever, which remains a serious health concern, particularly in developing countries. This study aimed to determine the antibacterial activity of butterfly pea flower extract obtained through a gradient maceration method using n-hexane and 70% ethanol as solvents. The butterfly pea powder was extracted using a gradient maceration method, starting with n-hexane followed by 70% ethanol. The resulting thick extract was subjected to phytochemical screening and antibacterial activity testing against Salmonella typhi using the well diffusion method. The tested concentrations were 50% and 100%, with 10% DMSO as the negative control and 5% chloramphenicol as the positive control. The results showed that the butterfly pea extract contained flavonoids, alkaloids, tannins, and saponins, which exhibited antibacterial activity against Salmonella typhi. The 70% ethanol extract at 100% concentration showed the highest inhibition zone with a diameter of 18,4 mm, followed by the 50% concentration with 14,4 mm. Meanwhile, the n-hexane extract showed smaller inhibition zones. The positive control (chloramphenicol) 5% produced an inhibition zone of 19,0 mm, while the negative control (DMSO) showed no inhibitory activity. The statistical analysis using the One Way ANOVA test showed a significant difference between the treatment groups (p = 0.000), confirming that the type of solvent and extract concentration affected the antibacterial activity.
