Pengobatan tanda, gejala, dan kekambuhan acne vulgaris cukup sulit dikarenakan P. acnes yang resisten dengan antibakteri seperti golongan linkosamida. Kunyit (Curcuma longa L.) mempunyai senyawa aktif kurkumin yang merupakan polifenol alami dengan sifat antibakteri terhadap P. acnes. Bakteri endofit yang diisolasi dari suatu tanaman dapat menghasilkan metabolit sekunder yang sama dengan tanaman aslinya. Penelitian bertujuan untuk mengetahui aktivitas antibakteri metabolit sekunder endofit kunyit terhadap P. acnes. Penelitian bersifat deskriptif yaitu isolat bakteri endofit kunyit diujikan dengan metode difusi cakram terhadap P. acnes. Isolat yang paling berpotensi memiliki aktivitas antibakteri diidentifikasi berdasarkan karakterisasi morfologi koloni, morfologi sel, biokimia dan dilakukan uji senyawa metabolit sekunder dengan menggunakan metode Ciulei. Sebanyak 12 dari 17 isolat memiliki aktivitas terhadap P. acnes dengan diameter zona hambat terbedar yaitu 21,2 mm dengan kode isolat H5. Hasil identifikasi menunjukkan bahwa H5 memiliki kemiripan dengan genus Bacillus. Hasil uji metabolit menunjukkan bahwa senyawa antibakteri yang dihasilkan isolat H5 yaitu saponin, terpenoid dan flavanoid.

Propionibacterium acnes is the main cause of acne vulgaris. Treatment to control the signs, symptoms, and recurrence of acne vulgaris is not easy due to its resistance to antibacterials such as linkosamide group. Turmeric (C. longa L.) has an active compound, curcumin, the main natural polyphenol which has antibacterial properties against P. acnes. Endophytic bacteria isolated from plant can produce same secondary metabolites with the host plant. The study aimed to determine the antibacterial activity of turmeric bacterial endophytes secondary metabolites against P. acnes. The research was descriptive research where endophytic bacterial isolates of turmeric were tested by disk diffusion method against P. acnes. The most potential isolates with antibacterial activity was identified based on the characterization of colony morphology, cell morphology, biochemical tests and a secondary metabolic compound test used Ciulei method. A total of 12 from 17 isolates had activity against P. acnes with the biggest inhibition zone is 21.2 mm with code H5. The identification results showed that H5 had similarities with the genus Bacillus. Metabolite test showed that the antibacterial compounds produced by H5 were saponins, terpenoids and flavonoids. The endophytic bacteria of turmeric plant has potential as an antibacterial against P. acnes. Key","PeriodicalId":314958,"journal":{"name":"Bioma : Jurnal Ilmiah Biologi","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125740794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pengambilan data dilakukan mulai November 2020 hingga Januari 2021 dengan alat tangkap durung. Titik sampling ditetapkan atas informasi dari masyarakat Desa Bandar Kumbul. Hubungan panjang-berat dihitung dengan Linear Allometrik Model (LAM), sedangkan faktor kondisi dihitung dengan rumus Fulton (K) dan berat relatif (Wr). Pola pertumbuhan ikan julung-julung (H. pogonognathus) mendapatkan hasil alometrik negatif dengan nilai b 2,9371 (b<3). Nilai koefisien Fulton (K) 2,57 dan koefisien berat relatif (Wr) 103,07. Hal ini menunjukkan bahwa pola pertumbuhan ikan julung-julung (H. pogonognathus) allometrik negatif dengan panjang tubuh lebih cepat dibandingkan berat tumbuh. Nilai (K) menunjukkan bahwa Aek Mailil masih dalam keadaan seimbang dan baik untuk mendukung kehidupan ikan julung-julung (H. pogonognathus). Kata kunci: faktor kondisi; Hemirhamphodon pogonognathus; pola pertumbuhan ABSTRACTLong-Weight relationship and condition factors of Julung-Julung (Hemirhamphodon pogonognathus) in Aek Mailil, Labuhanbatu Regency, North Sumatera, Indonesia. Hemirhamphodon pogonognathus is one of Indonesia's native fish species. Aek Mailil is one of the habitats for julung-julung (H. pogonognathus) in Labuhanbatu Regency. This study aimed to determine the relationship between length-weight and condition factors of julung-julung (H. pogonognathus) living in Aek Mailil. Sampling was carried out from November 2020 to January 2021 using durung fishing gear. The sampling points were determined based on information from the local community of Bandar Kumbul Village. The relationship of length-weight is calculated using the Linear Allometric Model (LAM), while the condition factor is calculated using the Fulton formula (K) and relative weight (Wr). The growth pattern of julung-julung (H. pogonognathus) got a negative allometric result with a b value of 2.9371 (b <3). The value of the Fulton coefficient (K) 2.57 and the relative weight coefficient (Wr) 103.07. This means that Aek Mailil's waters are in a balanced state and can support the (H. pogonognathus) live.Keywords: condition factor; Hemirhamphodon pogonognathus; growth pattern","PeriodicalId":314958,"journal":{"name":"Bioma : Jurnal Ilmiah Biologi","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133941205","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
