For the local market, Tilapia is much demanded alive because in a dead condition it will make the quality decline faster so that handling in the transportation system is the main key that must be considered. This study aimed to determine the effect of eugenol concentration on the quality of tilapia and water during semi-wet transport and to determine the most optimum concentration in maintaining the quality of tilapia. The concentration of eugenol 50 mg/L, 75 mg/L, and 100 mg/L were used, then control of pond water and control of inlet water as comparisons. Survival rate tests were carried out, fish quality was measured based on weight loss, proximate analysis, E. coli and Salmonella sp. microbial test, and water quality was measured based on pH, dissolved oxygen, ammonia, and nitrite test. The test was carried out before and after transportation with three repetitions. The results showed that in all treatments the survival rate of fish was 100%, there was no E. coli and Salmonella sp. content, weight loss decreased with the increase in eugenol concentration, and the proximate content was significantly different only in fat content. Then, for water quality test, it was found that after transportation the pH, dissolved oxygen, and ammonia values decreased where the higher the eugenol concentration the higher the pH, dissolved oxygen, and ammonia values. Meanwhile, nitrite content was only found in pond water control and inlet water control after transportation. At each concentration of eugenol there was nothing that made fish quality and water quality below the acceptable range. From the research results, it concluded that the eugenol concentration of 100 mg/L is the most optimum concentration in maintaining the quality of Tilapia in semi-wet live transport.
