Abstract
A research on utilization of fleshing waste at the tannery industry by vermicomposting have been conducted. The growth media consist of dung, fleshing waste, and stubbles. Ratio of dung and fleshing waste were varied at 100:0; 90:10; 80:20; 70:30; 60:40; and 50:50 respectively. All the media were fermented for three weeks and then proceeded by incubation process of earthworm for another six weeks. The changes of the volume per weight of media, the earthworm weight, C, N, and C/N ratio were observed and measured every week. The result showed that media volume per weight value were decreased in direct proportional to weight of the fleshing waste added in the media, those were 1.66; 1.64; 1.53; 1.50; 1.39; and 1.31 cm3/g, respectively. C/N ratio were below 15 for all combination of media ratio after two weeks incubation. The optimum result was achieved for compost with dung and fleshing waste ratio of 60:40.
