Abstract

Whey waste contains organic materials, particularly high complex proteins and amino acids in the form of suspended and dissolved solids, however the utilization of whey as a organic liquid fertilizer still has a less attention. Thus the Utilization of the whey waste through anaerobic process to be used as a organic liquid fertilizer is the purpose of the research. This research was conducted using factorial design with completely randomized 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, 3, and 5 days). The variables measured were the content of organic C, C/N Ratio, and Total N, P2O5 and K2O contents. The results showed that the fermented whey waste on the different fermentation time and yeast concentration had increased the organic C and C/N ratio, but decreased P2O5 and K2O contents. The utilization of whey combined with solid or other liquid wastes gave a chance to produce a quality organic liquid fertilizer
