Abstract
Feed is one main factor in aquaculture activities which influences the quantity and quality of aquaculture commodities. Feed can also increase the cultivated fish survivability to prevent from fish diseases. Binahong leaf powder is one material added in the fish feed making which contains active compounds functioning as antibacterial agent. This study did aim at examining the influence of Binahong leaf powder addition to feed on the prevalence and survival rate of Red Tilapia seeds infected by Aeromonas hydrophila bacteria. This research employed an experimental method using a randomized complete design with four treatments. Each treatment consisted of different Binahong leaf powder dosage used as the material in feed making with treatment A (5%), treatment B (7%), treatment C (9%), and treatment D (control). The test animals were ± 5 cm red tilapia seeds infected by Aeromonas hydrophila bacteria. Feeding was given twice, in the morning and evening with the feeding rate of 10% per day of the total body weight. The research results showed that the addition of Binahong leaf powder did not influence the prevalence and survival rate of red tilapia seeds infected by Aeromonas hydrophila bacteria.

Highlights
Freshwater fish farming is one business developed in many Indonesian territorial areas which is influenced by various factors including environmental quality, cultivation techniques, quantity and quality of feeds, as well as diseases caused by many bacteria and viruses (Salikin et al, 2014)
This study used Binahong leaf powder in the artificial feed making to determine its influence on the prevalence and survival rate of Tilapia seeds infected by A. hydrophila bacteria
The results showed that the Binahong leaf powder addition to the artificial feed making produced a different prevalence in the Tilapia seeds infected by A. hydrophila
Summary
Freshwater fish farming is one business developed in many Indonesian territorial areas which is influenced by various factors including environmental quality, cultivation techniques, quantity and quality of feeds, as well as diseases caused by many bacteria and viruses (Salikin et al, 2014). Diseases either caused by bacteria or viruses in freshwater fish farming are considered as one serious problem faced by the fish farmers as having the potential to cause great losses in the form of increasing fish mortality rate. Those diseases were experienced by the fish as the result of interaction between three components in aquatic ecosystems: weak host (fish), the existence of pathogenic organisms, and poor environmental quality. A research on the use of Binahong leaf powder in fish feed making functioning as an antibacterial agent for freshwater fish farming is greatly necessary to conduct
