| dc.description.abstract | Tanaman kaliandra (Calliandra calothyrsus) berpotensi sebagai sumber bakteri endofit yang berperan dalam meningkatkan pertumbuhan tanaman melalui produksi hormon Indole Acetic Acid (IAA). Penelitian ini bertujuan untuk mengisolasi dan mengkarakterisasi bakteri endofit dari tanaman kaliandra serta mengevaluasi potensinya sebagai penghasil IAA. Isolasi dilakukan dari jaringan akar dan batang menggunakan metode sterilisasi permukaan, diikuti pemurnian isolat, karakterisasi morfologi, uji hipersensitif pada daun Mirabilis jalapa, serta uji produksi IAA secara kualitatif menggunakan reagen Salkowski. Hasil penelitian menunjukkan bahwa diperoleh 20 isolat bakteri endofit, terdiri atas 14 isolat dari akar dan 6 isolat dari batang. Uji hipersensitif mengidentifikasi empat isolat non-patogen, yaitu BEBK 3, BEBK 4, BEBK 5, dan BEAK 4. Uji IAA menunjukkan bahwa dua isolat, BEBK 3 dan BEBK 5, berpotensi sebagai penghasil IAA. Hasil ini menunjukkan bahwa kaliandra merupakan sumber potensial bakteri endofit sebagai agen pemacu pertumbuhan tanaman. The plant Calliandra calothyrsus has potential as a source of endophytic bacteria that can enhance plant growth through the production of Indole Acetic Acid (IAA). This study aimed to isolate and characterize endophytic bacteria from C. calothyrsus and evaluate their potential as IAA-producing agents. Isolation was carried out from root and stem tissues using a surface sterilization method, followed by purification of isolates, morphological characterization, hypersensitivity testing on Mirabilis jalapa leaves, and qualitative IAA production testing using Salkowski reagent.The results showed that a total of 20 endophytic bacterial isolates were obtained, consisting of 14 isolates from roots and 6 isolates from stems. Hypersensitivity tests identified four non-pathogenic isolates, namely BEBK 3, BEBK 4, BEBK 5, and BEAK 4. IAA testing revealed that two isolates, BEBK 3 and BEBK 5, demonstrated potential as IAA producers. These findings indicate that C. calothyrsus is a promising source of endophytic bacteria that can be utilized as plant growth-promoting agents. | en_US |
