Abstract

Proses pembenihan udang vannamei melibatkan pengelolaan kondisi lingkungan dan kualitas air yang optimal untuk mendukung perkembangan larva. Kualitas air yang buruk dapat mendukung bakteri Vibrio sp. menyebar secara cepat. Parameter kualitas air seperti Total Organic Matter dan alkalinitas berpengaruh terhadap kelimpahan Vibrio sp. Penelitian ini dilakukan untuk mengetahui pengaruh TOM dan alkalinitas serta interaksinya terhadap pertumbuhan dan kelimpahan Vibrio sp. Pengujian ini dilakukan pada 3 kolam yaitu kolam A22, A23, dan A27. Parameter kualitas air yang diuji adalah Total Organic Matter (TOM), Alkalinitas, dan Total Vibrio Count (TVC). Pengujian tambahan juga dilakukan untuk parameter pH, Nitrit (NO2), dan Total Ammonium Nitrogen (TAN). Berdasarkan hasil pengujian menunjukkan bahwa kelimpahan bakteri Vibrio sp. di pembenihan udang vannamei tidak dipengaruhi secara signifikan oleh bahan organik dan alkalinitas. Hal ini tidak bisa terlepas dari faktor parameter kualitas air lainnya.

Abstract

The primary challenge encountered in the production of tilapia is a bacterial disease that is induced by the bacterium Aeromonas hydrophila. Crop failure and the mortality of cultured animals are among the consequences. Certain herbal plants contain antioxidants that can exert a therapeutic effect against the A. hydrophila bacterium. The objective of this investigation is to ascertain the survival of fish following infection with A. hydrophila bacteria and their behavior and morphology prior to and following immersion in purple sweet potato leaf extract (Ipomoea batatas). In the initial stage, the survival rate was assessed through the challenge test with A. hydrophila 108 bacteria. The second stage involved the observation of the behavior and morphology before and after immersion in purple sweet potato leaf extract (I. batatas). This research was conducted in two phases. The treatment concentrations were as follows: treatment A (without extract / 0 mg/L), treatment B (40 mg/L), treatment C (60 mg/L), and treatment D (80 mg/L). In the research, abnormal behavioral changes, including the presence of red sores on the tail and a decline of appetite, were observed. The fish maintained an appetite, exhibited normal body movements, and swam actively when treated with D. Conversely, treatment A demonstrated a subpar response until the conclusion of the observation period. The effective inhibition of mortality in Nile tilapia was demonstrated by the survival rate of Nile tilapia larvae infected with A. hydrophila bacteria after treatment with a solution of purple sweet potato leaf extract (I. batatas) for 24 hours. The survival rate was observed over a 7-day period.

Abstract

This study aims to analyze the effectiveness of various types of organic materials in cultivation media to enhance the production and quality of silkworms (Tubifex sp.). The method used is a Systematic Literature Review (SLR) based on the PRISMA approach. The results show that organic materials such as tofu waste, rice bran, poultry manure, cow dung, and household compost significantly affect silkworm biomass and nutritional content. The best outcomes were found in studies using mixed and fermented organic substrates, which improved growth and maintained the stability of the rearing environment. An ideal substrate is one that has a balanced C/N ratio, supports microbial activity, and maintains stable physical-chemical media conditions. This study concludes that locally available organic materials, when properly managed, offer strong potential to support sustainable and environmentally friendly Tubifex cultivation systems.

Abstract

The condition of coral reefs on Gili Noko Island has decreased due to climate change and human activities. The initial survey results showed a medium damage category on coral reefs and the dominance of Dead Coral with Algae (DCA). This research was conducted in the waters of Gili Noko Island, Bawean which was divided into 4 stations with the aim of describing oceanographic conditions, describing DCA characters and analyzing various factors that cause DCA abundance on Gili Noko Island. This research was conducted from November 2024 to July 2025. The method used was the Underwater Photo Transect (UPT) method to see the percentage of coral cover. Coral cover abundance data were analyzed using Coral Point Count with Excel Extensions (CPCe) software. Data on oceanographic parameters and water quality were taken in situ and tested in the laboratory using the UV Vis spectrophotometer method to see the content of nitrate and phosphate. The research data were analyzed using Principal Component Analysis (PCA) to determine the correlation between DCA abundance and physico-chemical water quality parameters. The results showed that the physico-chemical parameters reflect the tropical waters of Gili Noko Island and support the life of marine organisms including coral reefs. DCA abundance was found at all observation stations with the highest abundance at station 1 at 48.3%. This was caused by the high nitrate concentration of 0.2532 mg/L. DCA abundance on coral reefs is dominated by turf algae or benthic macroalgae. The PCA correlation results showed the DCA abundance factor was influenced by nitrate concentration.

Abstract

This study investigated the relationship between habitat substrate, water quality parameters and ornamental fish distribution in the waters of Serangan Island, Bali. Using a community ecology approach, this study found that coral substrate supported higher diversity and abundance of ornamental fish species than sand and coral-sand substrate. Water quality parameters such as dissolved oxygen, salinity, water brightness and pH showed significant influence on species distribution. Species identification provided detailed data on morphology, meristics and conservation status based on the IUCN Red List. These results confirm the importance of coral habitat conservation and water quality management to support the sustainability of ornamental fish populations in the region
