Abstract

The bacteria Vibrio parahaemolyticus and V. campbellii are the pathogens of Vibriosis in various marine cultured organisms. Moreover, Aeromonas hydrophila is the pathogen of the Motile Aeromonad Septicemia (MAS) disease. Therefore, it is needed to inhibit these bacteria's activity. Studies showed that the extract of seaweed Kappaphycus alvarezii could hinder the growth of gram-negative and gram-positive bacteria; however, the antibacterial activities against V. parahaemolyticus, V. campbellii, and Aeromonas hydrophila remain unknown. Thus, this study aimed to analyze the antibacterial activity, and the minimum inhibitory concentration of K. alvarezii extract against V. parahaemolyticus, V. campbellii, and A. hydrophila. K. alvarezii was collected from the cultured in the Geger Beach area, Badung Regency. The methanol K. alvarezii extracts with different concentrations (10, 5, 1, 0.05%) were dropped to the paper disk and placed on the bacterial tested cultures. Inhibition zone measurements were carried out every 6 hours during the 24-hour incubation period. Chloramphenicol and methanol were also tested as the positive and negative control, respectively. Results showed that the antibacterial activity was only demonstrated in 10% extract against V. campbellii with an inhibition zone of 12.5 mm.

Abstract

Tambak udang vaname (Litopenaeus vannamei) banyak ditemukan di Indonesia dan membutuhkan pengelolaan kualitas air yang baik untuk mendukung pertumbuhan dan kesehatan udang. Meskipun udang vaname relatif tahan terhadap beberapa penyakit, ia tetap rentan terhadap infeksi bakteri Vibrio dan virus Infectious Myonecrosis Virus (IMNV), yang dapat menurunkan kualitas produksi udang akibat kerusakan otot dan infeksi sekunder. Kelimpahan Vibrio mengacu pada jumlah bakteri dari genus Vibrio dalam air, yang dapat memperburuk kesehatan udang, terutama jika dipengaruhi oleh faktor lingkungan seperti suhu, pH, dan kualitas air yang buruk. Sementara itu, total bakteri mengacu pada jumlah keseluruhan bakteri dalam sampel air, baik yang menguntungkan maupun patogen, yang penting untuk menilai kualitas ekosistem tambak dan potensi risiko kesehatan bagi udang. Penelitian ini bertujuan untuk mengetahui kelimpahan bakteri Vibrio dan total bakteri pada air tambak udang vaname yang terindikasi terjangkit IMNV. Penelitian ini menggunakan metode deskriptif kuantitatif dengan teknik kultur mikrobiologi untuk menghitung kelimpahan Vibrio dan total bakteri. Sampel air diambil dari tambak yang terindikasi terjangkit IMNV di Bali, dengan analisis parameter kualitas air seperti salinitas, suhu, pH, DO, nitrit, dan amonia. Hasil penelitian menunjukkan kelimpahan Vibrio rata-rata 2 x 10⁴ cfu/mL dan total bakteri 3.17 x 10⁶ cfu/mL. Kualitas air tambak tersebut menunjukkan kondisi yang mendukung pertumbuhan bakteri, dengan nilai TSS dan amonia yang tinggi meningkatkan risiko bakteri patogen.

Abstract

White Feces Disease (WFD), which infects Pacific white shrimp (Litopenaeus vannamei), poses a serious challenge in aquaculture due to its potential to cause mass mortality and substantial economic losses. One of the main causes of this disease is bacterial infection from the genus Vibrio. The use of natural substances, such as garlic (Allium sativum) extract, is considered a more environmentally friendly and sustainable alternative for disease control. This study aimed to examine the effect and determine the optimal concentration of garlic extract in inhibiting the growth of Vibrio sp. isolated from WFD-infected L. vannamei ponds, cultured on TCBS media. The study was conducted in vitro using the disc diffusion method with four extract concentrations (25%, 50%, 75%, and 100%) against two bacterial isolates, designated as isolate A and isolate B. The results showed that garlic extract was able to inhibit the growth of Vibrio sp., with the largest inhibition zone observed in isolate A at 75% concentration (14.8 mm) and in isolate B at 100% concentration (19.3 mm). These findings indicate the potential of garlic as a natural antibacterial agent to inhibit pathogenic bacteria and support the sustainability of shrimp aquaculture.
