This study aimed to determine the effect of eugenol concentration on the survival and quality of tilapia (Oreochromis niloticus) during dry transport. The effect of eugenol concentration was determined with three concentration treatments (50, 75, and 100 mg/L) using a dry system and control (0 mg/L) using pond and inlet water with a wet system during transportation with three repetitions. Determining the effectiveness of eugenol concentration use was based on survival tests, weight loss, water quality tests including DO, pH, nitrite, and ammonia, microbial tests, and proximate and gross energy analysis. The results showed that the survival rate of tilapia decreased with the increase in the concentration of eugenol used, but the survival rate of all treatments was high. The weight loss of control tilapia was greater than eugenol treatments but had no significant effect. Based on the water quality during anaesthesia and revitalization, it was found that each anaesthetic treatment had pH, DO, ammonia, and nitrite values in good conditions within safe standard limits. In the microbial test, no microbes were found, so all tilapia were of good quality. The results of the analysis of proximate content and gross energy did not significantly differ between the addition of the eugenol concentration and after being transported. The research results show that the most effective concentration of the eugenol for the dry transportation of live tilapia is the eugenol 50 mg/L treatment with a survival rate of 92% and based on the simulation of profit and loss analysis carried out dry transportation with eugenol 50 mg/L provides higher economic benefits than the wet system (control).
