Abstract

Marine beef is a meat product that has been fat dissolved so that the protein is a major part of the product. Marine beef dry form solid and hydrophilic, has a different performance from the base ingredients, but still contains nutrients according to the characteristics of the original. Weakness marine beef products is shaped in the form of flour so it does not allow for direct consumption. Suweg addition of flour mixture and emulsifier in the manufacturing process can serve as a regulator of the water content, hardness and adhesion to produce a final product that is more compact and high taste. This study aims to determine how optimal levels suweg flour and Na-CMC can be added to marine beef in order to obtain dry products based marine beef with the physical properties, the speed of rehydration and sensory properties that aroma, flavor and texture is good and acceptable to consumers. Treatment of dry meatballs are rich in protein from marine beef with the addition of flour suweg 15% and 1% Na-CMC is the best treatment with the shortest rehidrated pace with time 130 seconds at a temperature of boiling water and the scent of the most preferred by the panelists organoleptic test.Key word: marine beef, protein rich meatballs, suweg, Na-CMC

Abstract

The unpleasant smell of dung fly everywhere, dirt strewn everywhere be a factor for the emergence of social conflict surrounding of cow breeding. Biogas digester in the form of a closed tube can be used for cow dung that is no longer scattered and the scent is not pleasant been isolated. Not only that bio-gas produced can be used together with the communities around the farm, which in turn not only relieve social turmoil but rather strengthen the social fabric. Now they jointly maintain and care for the sake of expediency digester together. Bio-gas digester constructed is fixed dome models (fixed dome) with capacities of 10 m3 of manure. It means being able to accommodate dirt 10-15 cow. After 60 days of curing in the tube digester, biogas digester turns is able to produce enough gas used for cooking purposes 15 families around the farm together.Keywords: digester, biogas, cow breeding, social conflict
