Abstract

Whey waste contains organic materials, particularly high complex proteins and aminoacids in the form of suspended and dissolved solids, however the utilization of whey as aorganic liquid fertilizer still has a less attention. Thus the Utilization of the whey wastethrough anaerobic process to be used as a organic liquid fertilizer is the purpose of theresearch. This research was conducted using factorial design with completelyrandomized design (CRD) which consists of two factors: the yeast concentration(without yeast; 0.25 and 0.50 g/500 ml of whey waste) and the fermentation time (0, 3and 5 days). The variables measured were the content of organic C, C/N Ratio, and TotaN, P2O5 and K2O contents. The results showed that the fermented whey waste on thdifferent fermentation time and yeast concentration had increased the organic C andC/N ratio, but decreased P2O5 and K2O contents. The utilization of whey combined withsolid or other liquid wastes gave a chance to produce a quality organic liquid fertilizer.
