Abstract:
Gourami fish is a consumption fish with quite high economic value. Palm oil sludge as a
waste product from palm oil production has a protein content that is not much different from
rice bran. This study aims to analyze the effect of bran substitution with palm oil mud
fermentation in artificial feed and analyze the percentage of the best dose for growth (GR)
and survival (SR) of gourami fry (Osphronemus gouramy). The method used was
experimental, Completely Randomized Design (CRD) with 5 treatments and 3 replications
each with different doses of palm oil sludge fermentation and bran substitutes. Ferlawite
dose in each treatment P1 (0%); P2 (2.5%); P3 (5%); P4 (7.5%); P5 (10%). The research
was carried out from March – October 2023, carried out in 2 places, feed formulation and
printing was carried out at the Nutrition Laboratory of the Faculty of Fisheries and Marine
Affairs, Lambung Mangkurat University, for fish rearing was carried out in the farmer's pond
located in Labuan Tabu Village, Martapura District, Banjar Regency City. The research
results were based on statistical analysis, the substitution of bran with fermented palm oil
mud (ferlawit) had no significant effect (Fhit<Ftable) on GR, SGR, FCR, and SR. The best
percentage of substitution of bran with ferlawite for GR (12.55%) and SR (90%) gourami fish
seeds is at a dose of 5% (ferlawite 5% and bran 5%)
