Density of Infusoria On The Substrate of Banana Leaves, Ketapang Leaves, Rice Straw and Corn Husk

One of the natural foods used by fish breeders is infusoria, which is a small group of single-celled organisms. The infusoria plant substrates that can be used include banana leaves, ketapang leaves, rice straw, and corn husk. In practice, infusoria cultivators do not know the type and mass of the substrate that has the maximum density output of the infusori cultivated. The study aims to evaluate the influence of the type and mass of the substrate on the infurosia density. This study is an experimental study of the Complete Random Design ( CRD ) two-factor treatment of the substrate type (banana leaves, ketapang leaves, rice straw, and corn husk) and the mass of the substratum (1 g and 5 g) with 5 repetitions. The research phase includes sample preparation and sample analysis. Sample analysis includes measurement of pH, temperature, density. Data analysis using Two Way ANOVA and Tukey tests at a significance level of 5%. The results of the study showed that the type and mass of the substrate had a significant influence (P sig. <0.05) on the infusory density and there was no interaction between the two variables. The corn husk has the lowest density and differs significantly from the substrates of banana leaves, ketapang leaves and rice straw. The mass of the substrate 5 g has the highest density compared to the mass of 1 g.
