Abstract

The production of aquaculture in East Kalimantan Province in 2023 was recorded at 162,124 tons. This data indicates that the need for fish feed (pellets) is also very large. Meanwhile, it is known that the price of feed continues to climb. This study aims to observe the effect of the use of palm kernel meal, as an alternative feed ingredient, which is fermented using EM4 with different doses on the activity of digestive enzymes and the growth of gourami fish weight. The doses of EM4 used were 0 mL/kg (P1), 4 mL/kg (P2), and 8 mL/kg (P3). Based on the results of the analysis of variance, it was known that the inclusion of fermented palm kernel meal significantly (P<0.05) affected activities of amylase, protease, and lipase enzymes. The highest value of digestive enzyme activity was observed in P2 which produced amylase enzyme activity of 6.31 U/mL, protease 0.46 U/mL, and lipase 0.38 U/mL, and then followed by P3 which produced amylase enzyme activity of 4.76 U/mL, protease 0.39 U/mL, and lipase 0.35 U/mL. The lowest value of activity was observed in gourami treated with P1 which produced amylase enzyme activity of 4.048 U/mL, protease 0.36 U/mL, and lipase 0.31 U/mL. Analysis of variance also showed that fermented palm kernel meal had a significant effect (P<0.05) on the weight growth of giant gourami. The highest weight gain was produced by P3 (2.16 g), then followed by P2 (1.79 g), and P1 (1.21 g). The best feed conversion was produced by P2 (2.32), followed by P3 (2.94), and P1 (3.28).

Abstract

Amphilopus trimaculatus (Louhan in Indonesia) is a freshwater ornamental fish that is famous among the public because it is believed to bring good luck to its owner, so it has a fairly high selling price. Keeping flowerhorn fish requires food so that the fish can grow well. This research aims to analyze the nutritional value of artificial feed made from palm kernel meal which is fermented using EM4 for different lengths of time and to analyze its effect on the growth and feed conversion ratio of flowerhorn fish. This research used a Completely Randomized Design (CRD) with 4 treatments and 3 replications. The treatments applied were P1 not fermented, P2 fermented for 3 days, P3 fermented for 5 days and P4 fermented for 7 days. The fish used in this study had an initial length of 3-5 cm and an initial weight of 1.5-2 g. Fish were kept for 40 days in aquariums measuring 30×30×40 cm using a recirculation system. Each aquarium is filled with 20 liters of water with a stocking density of 10 fish/aquarium. Fish were fed 3 times a day using ad-satiation. The results of the proximate nutritional analysis of the feed showed that the protein content of the feed was 32.53%, 35.97%, 37.31% and 36.31% for P1, P2, P3 and P4 respectively. The feed fat content was 6.19%, 7.26%, 6.38% and 7.44% for P1, P2, P3 and P4 respectively. Data analysis was carried out using analysis of variance (ANOVA) with a confidence level of 95% and continued with the Duncan Multiple Range Test (DMRT). The best fish growth performance and feed conversion ratio were achieved by P2, although statistically there was no significant difference in fish growth (P<0.05) but had a significant effect on the feed conversion ratio (P>0.05).

Abstract

A by-product of the palm oil business, palm kernel meal can be utilised as an alternate feed ingredient for cultured fish because of its really decent nutritional value. This research aimed to analyze the nutritional value of artificial feed with different EM4 concentrations in palm kernel cake fermentation and to analyze its effects on absolute weight growth, daily growth rate, specific growth rate, and feed conversion ratio. A Completely Randomized Design (CRD) with 3 treatments and 4 replications each was applied in this research. The treatments applied were unfermented palm kernel cake flour (P1), palm kernel cake fermented with 4 ml/kg concentration (P2), and palm kernel cake fermented with 8 ml/kg concentration (P3). The results of feed nutritional assesment showed that protein content of P1 (26.96%); P2 (38.51%); and P3 (38.71%); fat content in feed, P1 (6.62%); P2 (6.48%); and P3 (6.63%); Absolute weight growth P1 (0.78 g); P2 (1.18 g); and P3 (1.54 g); Daily growth rate, P1 (0.71%); P2 (1.10%); and P3 (1.31%); Total length growth, P1 (0.66 cm); P2 (0.74 cm); and P3 (0.99 cm); and Feed conversion ratio, P1 (3.28); P2 (2.34); and P3 (1.73). The results of the analysis of variance (ANOVA) at a 95% confidence level showed that different EM4 concentration treatments in palm kernel meal fermentation had a significant effect on growth, feed conversion ratio, and SGR (Specific Growth Rate) in Gourami Fish (Osphronemus gouramy).

Abstract

The aim of this study was to analyze of the survival rate, growth rate, feed efficiency, and feed conversion ratio and than determine of the best dose for probiotic supplementation on hoven’s carp fish fry (Leptobarbus hoevenii). This study used a completely randomized design (CRD) which consisted of four treatments and three replications. Treatment of artificial feeding with probiotic supplementation as much as 0 ml kg-1 of feed, 4 ml kg-1 of feed, 8 ml kg-1 of feed, and 12 ml kg-1 of feed. The results showed that probiotic supplementation with different doses on artificial feed showed a significant effect on absolut weight growth rate, specific growth rate, feed efficiency, and feed conversion ratio (P<0.05) but did not have a significant effect on survival rate, and total length growth rate on hoven’s carp fish fry (P>0.05). The results of this study also showed that supplementation with probiotic doses of 12 ml kg-1 of feed produced the highest values for total length growth rate, absolut weight growth rate, specific growth rate, survival rate, and feed efficiency, as well as with the lowest feed conversion ratio values.
