Effect of Addition of Banana Peel Extract on Commercial Feed as an Effort to Reduce Patin Cannibalism (Pangasius hypophthalmus) Larval Stage

This research aims to determine the best concentration of banana peel extract used in commercial feed on the survival of patin fish larvae. The research was conducted on April 2, 2019 until June 1, 2019 which took place at the Aquaculture Laboratory of the Faculty of Fisheries and Marine Sciences, Padjadjaran University. The making of banana peel extract was carried out at the Central Labforatory, Padjadjaran University. The research method was carried out experimentally with Completely Randomized Design (CRD). This research uses five treatments that are repeated three times. The treatment in this research consisted of the addition of banana peel extract on commercial feed at a dose of 0%, 0.50%, 0.75%, 1.00 and 1.25% per kilogram of feed. The parameters observed in this research were survival, absolute length growth, daily growth rate, and water quality. The analysis used is the f test and descriptive analysis. Parameters tested using the f test include survival, absolute length growth, and daily growth rate. While water quality was tested descriptively. Survival rates, absolute length growth, and growth rates ranged from 75.33% to 86.96%, 1.29 - 1.32 cm and 2.95% -3.00% respectively. The observation of water quality include temperature, pH and DO respectively waters ranged from 28.00 to 30.20 °C, 7.22 to 8.18 and 5.40 to 6.70 mg /L. Based on research results concluded that the concentration of banana peel extract 0% - 1% produced a survival rate of 81.70% - 86.96% and was better than the addition of banana peel extract with a concentration of 1.25% which resulted in a survival rate of 75.53%. The suggestion from this study is to improve the survival of patin fish larvae can be added banana peel extract with a concentration of 0.75% or equivalent to 7.5 g / Kg of feed.
