MetadataShow full item record
Dead fi sh aft er upwelling phenomena in Cirata Reservoir cause environmental pollution if it is not well managed. Use of the waste to be processed become organic fertilizer will be useful. Th e purpose of this research was to use the fi sh waste added activator of Gliocladium sp on kascing media to be processed as organic fertilizer increasing its quality. Organic fertilizers were made by mixing fi sh wastes and kascing with proportion as follows: A (80%:20%), B (70%:30%), and C (60%:40%). Each proportion was added with Gliocladium sp. (0%, 2%, 3%, 4%, and 5%). Organic fertilizer had N total between 4.06-5.46%, organic C 14.98-18.61%, C/N ratio between 2.79-4.27, 1.35-2.78% of P and 1.01-0.78% of K. Th e product containing 60% fi sh wastes was to be the best based on its nutrient compositions.
