- This research aims to determine the method of adding potassium diformate to commercial feed to increase survival and growth in gourami juvenile. The method used in this research is an experimental method using a Completely Randomized Design (CRD), consists of four treatments and four replications. The treatments used are (A) Without giving Potassium diformate (control), (B) giving potassium diformate by 0.3%, (C) giving potassium diformate by 0.5% and (D) giving potassium diformate by 0.8%. The test fish used was 300 giant gourami with a length of 4-6 cm. The containers used in this research were aquariums with a size of 40 × 30 × 40 cm3 that reared in 16 aquariums. The density of giant gourami fingerlings during the research was 10 fish per aquarium. The rearing period was 40 days. The feed given was 3% of body mass. Water quality parameters (temperature, pH and dissolved oxygen) were observed every 10 days. Other parameters are the daily growth rate, feed efficiency, the survival rate and the acidity of intestinal and stomach which were observed every 10 days. The results showed that the addition of potassium diformate by 0.3% gives the best results of daily growth rate of 1.31%, feeding efficiency of 37.18%, survival rate of 100% and decreased acidity in the intestine and stomach which helps in the process of protein absorption.
