Co-composting cow manure, rice straw with marine organic waste: characterization of compost quality

Abstract Marine organic waste can be managed into compost products. Co-composting is a biological process to decompose two or more types of matter stable humus substance and expected overcome the disadvantages composting single matter. This study aims produce with better characteristics than marine singly addition other materials such as cow dung rice straw. The method used Barkley for 7 weeks. Parameters observed were pH, temperature, humidity, C/N, macronutrients, micronutrients, physical properties odor, color, texture. Compost quality have met Indonesian national standard (SNI SNI 19-7030-2004) so that it developed. macronutrients (Nitrogen 1.47%; Phosphorus 0.38% Potassium 0.28%) micronutrients (Fe 0.97%; Mn 0.09%; Zn 47.74 ppm Cu 7.43 ppm).
