Abstract

Mutiara catfish, the second largest food fish in Magelang Regency, faces challenges due to high feed prices. To address this, researchers are exploring the use of crude glycerin biodiesel waste as an alternative feed. This research aims to determine the potential of crude glycerin as an alternative feed for mutiara catfish and its impact on their growth. The study involved selecting feed raw materials, formulation, manufacturing, feeding, observing fish growth, water quality, and proximate testing of test feed. The research used a randomized design with four treatments and three replications. The test feed consisted of P1 25% crude glycerin, P2 50% crude glycerin, P3 75% crude glycerin, and PK, a control in the form of pellets. Feeding was carried out twice a day using the ad satiation method. The study found that the P1 25% crude glycerin feed had the second-best results regarding 19 grams weight gain, 67.85% specific growth rate, 8 cm length growth, and 0.05 feed conversion ratio. The feed also had a 100% survival rate. The water quality was measured, with temperature and pH values ranging between 25-30℃ and 6.98-7.63. The proximate test results showed that the P1 feed had the second-best 12.70% water content, 20.51% ash content, 1.47% fat content, 15.04% protein content, and 50.28% carbohydrate content. The study concluded that the test feed effectively influences fish growth, but further research is needed to optimize feed nutrition.

Abstract

abstrak Crude glycerin is a main byproduct of biodiesel plants that has the potential to be used as a feed ingredient, but has not been fully utilized With the increasing biodiesel production, the quantity of crude glycerin is also rising, which could have environmental impacts if not wisely managed. However, research on using crude glycerin as fish feed in Indonesia is still limited Previous studies have not yet shown optimal results, so further research is needed to optimize the nutrition in feed formulations This study aims to determine the appropriate feed formulation to enhance the nutrition of alternative crude glycerin feed for pearl catfish (Clarias gariepinus). The research method utilized the Pearson square method to formulate feed and conducted proximate analysis to determine the nutritional content of the feed The results of this study indicate that sample code A has a higher protein content of 14,85% compared to sample code B, which is 11,86% Further research is recommended to achieve better results It is suggested to use an oven for drying to ensure complete dryness of the pellets and reduce water content.
