The production of earthworm biomass is one of the means to provide nutritive feed source for animal especially for cheap protein feedstuffs. Feeding earthworm with animal__ampersandsignrsquo;s feces leads to low biomass production. Takara is a waste product of tofu industry. It canbe used to speed up the production of earthworm. Therefore, this study was conducted to evaluate the combination of takara and diary feces as earthworm__ampersandsignrsquo;s feed toward the biomass production of Lumbricusrubellus. This experiment was carried out based oncompletely randomized design with five treatments of feed combination between takara and dairy cow feces. The treatments were performed in four replications within three weeks. The result on this study indicates that 75% of takara combined with 25 % of dairy cow feces significantly increases the biomass production of Lumbricusrubellus. It is not suggested to use 100% of takara as earthworm__ampersandsignrsquo;s feed.
