Abstract

Indonesia has a lot of potential in natural resources, one of which is seaweed. Seaweed is one of the natural ingredients that contain water-soluble dietary fiber. The fiber content in seaweed can be categorized as a functional food. The fiber content in seaweed varies, from 36-60% dry weight, 55-70% of the former percentage is soluble fiber consisting of alginate and carrageenan with varying amounts depending on the type of seaweed and environmental conditions. The dietary fibers are useful for disease prevention and health maintenance. Dietary fiber can prevent several diseases, including coronary heart disease (cardiovascular). The effect of dietary fiber according to Liu et al (2002) is a very high fiber diet (55 g/1,000 kcal) which resulted in a 33% reduction in LDL cholesterol (Low-Density Lipoprotein) in two weeks period. The mechanism of dietary fiber reduces cardiovascular disease since it is able to bind bile acids (the end product of cholesterol), thereby preventing its reabsorption from the intestine. Cholesterol that is bound to bile acids and lignin/pectin cannot be absorbed by the intestines but will be excreted in the feces.

Abstract

Pandu nile tilapia (Oreochromis niloticus) is one of the essential commodities for freshwater aquaculture that can be cultivated for breeding and growing out. This commodity has a huge business prospect with relatively high price in the market. Nile Tilapia Pandu is a crossbreed fish with fast growth and high economic value because of the ease of cultivation method, popular taste, and wide environmental tolerance. Therefore, the purpose of this article was to investigate breeding techniques, facilities, infrastructure, and challenges of O. niloticus breeding conducted at Loka PBIAT Janti. In addition, this article also provided business feasibility analysis to find out the business prospect of O. niloticus breeding. This article described the Pandu Nile Tilapia breeding techniques include pond preparation, broodstock preparation, spawning, egg hatching, larva rearing, nursery, harvesting, pest and disease control, and water quality control. The results of observations in O. niloticus breeding are the fecundity of 958 eggs, the fertilization rate (FR) of 95.29%, the hatching rate (HR) of 96.62%, and the survival rate (SR) of 91.47%, the water quality showed a suitable and optimal results for O. niloticus breeding. The results of business feasibility analysis revealed that total revenue gained was Rp. 18.400.000., with BEP unit was 24,35 Kg and BEP price was Rp. 1.351.584,-.
