This research aimed to determine the optimal dosage of potassium diformate addition to commercial feed in order to increase the growth and survival rate of common carp seeds. The method used in this research was experimental in a completely randomized design (CRD) consisting of five treatments and four replications. The treatments used were A (control), B with addition of potassium diformate (0.2%), C (0.3%), D (0.4%), and E (0.5%). For test fish, there were 200 of Common carp seeds with a size of 2-3 cm. The media used was 20 aquariums with a size of 40x30x40 cm3 and a stocking density of 10 individuals/aquarium. The rearing period was 35 days and the amount of feed given was 3% of the fish body weight. The parameters observed included water quality (temperature, pH, and dissolved oxygen) which were observed every 7 days for 35 days. Other parameters monitored were daily growth rate, survival rate, feed efficiency, and the acidity level of the intestine. The results showed that 0.3% addition of potassium diformate gave the best results with a daily growth rate value of 3.21%, highest survival of 98%, efficiency of feed utilization of 64.83%, and a decrease in intestinal pH which helped the process of protein absorption in the fish body. In conclution, the addition of potassium diformate has good effect on growth and survival rates of common carp.
