Catfish is kind of high economic fish with simple cultivation. But farmers typically pay 40-89% of total costs for buying feed. The purpose of this research was to describe the effect of pineapple peel filtrate (PPF) and probiotic Lactobacillus casei FNCC 0090 increments on catfish growth. This research used a randomized block design with three replicates. The variables were concentration of PPF (0%, 1% and 2%) and probiotic (0% and 1%). Parameters measured were SGR, FCR and SR of catfish, total energy of modified feed and probiotic growth with PPF. The feed was fermented for 30 minutes before given to catfish (size 5-8 cm). Data were analyzed using one-way ANOVA and DMRT test. The results showed that PPF and probiotic increments in feed did not have a significant effect on SGR, FCR or SR. Feed B (commercial feed + 1% PPF) had the best effect on SGR and FCR, 4.550 ± 0.826% and 0.153 ± 0.023, respectively. Feed C (commercial feed + 1% PPF) had the best effect on SR, 77.083 ± 23.662%. Feed E (commercial feed + 1% PPF + 1% probiotic) had the highest total energy, 4230.12 kcal/g and 2% PPF increased probiotic to 8.3 x 108 CFU/mL. © 2018 Author(s).
