Abstract

EM-4 probiotic solution is used in a fermentation process to lower the crude fiber in lemna cake and raise the protein content of the raw materials. The research aims to determine the difference in fermentation duration of plant-based feed using EM-4 solution on the improvement of quality and nutritional value of Nile tilapia feed.  The object of the research is artificial feed with 30% protein composed of various vegetable ingredients which is then fermented according to the research design. The study was consisting of 4 treatments: A: 1-day fermentation, B: 3-day fermentation, C: 5-day fermentation, D: 7-day fermentation. Data collection involved chemical and physical testing of the feed. The results of this research showed that the longer the fermentation, the protein content becomes higher while the carbohydrate and crude fiber content decreases. Therefore, the physical tests of the feed included buoyancy, water stability, and feed hardness shows no difference in each treatment. Seven days fermentation shows the best values on nutritional values. The combination of EM-4 with artificial feed made from vegetable ingredients can be recommended as fish feed because it fulfills protein nutritional needs to increase fish growth and development.

Abstract

Indonesia's high biodiversity has great potential to be developed in various fields, including fisheries. To support sustainable and environmentally friendly aquaculture activities, the utilization of local natural resources is one of the keys to increasing the competitiveness of the national fisheries sector amid global challenges related to food security and the environment. One alternative source that can be used as a natural feed supplement in fish farming is from the Curcuma genus, such as white turmeric (Curcuma mangga Val). Therefore, the purpose of this study was to determine the effectiveness of white turmeric extract (Curcuma mangga Val) on the growth of tilapia. The research design used was a completely randomized design consisting of 3 treatments and 3 replicates, namely: Treatment A (feed without turmeric extract), Treatment B (feed added with 5 ml of white turmeric extract), and Treatment C (feed added with 10 ml of white turmeric extract). Feed was administered three times daily at a dose of 5% of body weight. The results showed that the addition of white turmeric extract (Curcuma mangga Val.) significantly increased the growth of Nile tilapia (Oreochromis niloticus). The most effective treatment dose was Treatment C (10 ml/kg of feed), which resulted in an absolute average increase of 8.99 g in weight and 2.67 cm in length.
