FERMENTATION OF SOLID WASTE PALM OIL (ELAEIS) AS A GRAN SUBTITUTION FOR GOURAMY FRY (OSPHRONEMUS GOURAMY) FEED
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%).
