Abstract

Ornamental fish is a type of fish that lives in fresh water or in the sea that has a beautiful and attractive body shape or color. One type of freshwater ornamental fish that has a unique difference from the others is Betta ornamental fish. Betta fish is one type of ornamental fish that is in demand by the public, but the breeders of this betta fish are mostly confused about how to increase the brightness of the color of betta fish. Based on this background, this study aims to determine the effect of adding carrot flour with different concentrations in commercial feed on the color intensity of halfmoon betta fish (Betta splendens).This study used an experimental method with a Complete Randomized Design (RAL) of 4 treatments and 3 repeats. Then the variables observed include, fish brightness, fish weight, fish length, fish daily length, fish survival, and water quality. Furthermore, the observed data and data processing is carried out with SPSS statistical software 25.The addition of carrot flour in commercial feed can affect markedly (P>0.05). The addition of P4 treatment carrot flour at a dose of 95% pellets and 15% carrot flour in commercial feed, gave good results on the brightness of the color of Betta fish with an average value of 5.0 compared to other treatments that were given the addition of less carrot flour.

Abstract

This study aims to examine the effect of probiotic (Probio-7) supplementation on the Specific Growth Rate (SGR), Feed Conversion Ratio (FCR), and Survival Rate (SR) of Nile tilapia (Oreochromis niloticus). The research was conducted from January to March 2025 at the UNU Purwokerto Laboratory. An experimental method was used with a completely randomized design (CRD), consisting of 4 treatments and 3 replications. The treatments were: P1 (feed without probiotics), P2 (feed with 8 ml/kg probiotic), P3 (feed with 10 ml/kg probiotic), and P4 (feed with 12 ml/kg probiotic). The fish used were Nile tilapia (Oreochromis niloticus) with an average length of 6.53±0.35 cm and an average weight of 2.28±0.02 g. Feed was given at 08:00 and 16:00 until satiation. Stocking density was 15 fish per container filled with 15 liters of water, and the maintenance lasted for 30 days. The feed used was commercial pellet feed supplemented with probiotics according to the treatment, containing 32% protein. The results showed that the addition of probiotics (Probio-7) had a significant effect (P<0.05) on Specific Growth Rate (SGR), Feed Conversion Ratio (FCR), and Survival Rate (SR). Treatment P4 had the highest SGR value of 2.08±0.03 g, the lowest FCR of 0.33±0.02, and the highest Survival Rate (SR) of 84±7%. Keywords: Feed Conversion Ratio; Tilapia; Probiotics; Survival Rate
