The effectiveness of additional silage of fish ofal and bagasse fermentation on biomass and population of silk worm ( Tubifex tubifex)

The purpose of this study was to determine the effect of giving catfish offal silage and sugarcane bagasse fermentation to the biomass The method used in this research is experimental using Completely Randomized Design (CRD). The treatments were 413 gram (100%) rice field mud, 206.5 gram rice field mud + 75% fish offal silage + 25% bagasse fermentation, 206.5 gram rice field mud + 50% fish offal silage + 50% bagasse fermentation, rice field mud 206.5 grams + 25% silage of fish offal + 75% bagasse fermentation. Each treatment was repeated five times. The results showed that the highest peak of silk worm biomass with 206.5 grams of rice field mud culture + 25% fish offal silage + 75% bagasse fermentation with an average of 22.25 grams and the lowest biomass was produced on 406 grams (100%) mud media. Rice fields with an average of 7.15 grams. The highest population of silkworms was found in 206.5 gram rice field mud media + 25% fish offal silage + 75% bagasse fermentation obtained 6651 ind, the lowest population in 406 gram (100%) rice field mud media with an average of 2.263 ind.
