The use of rumen and chicken inside with addition of brown sugar as a possible liquid organic fertilizer was studied. The initial process is composting the mixture of rumen and chicken inside with various proportion. The releasing CO2 is used as indicator for composting process. The next stage is to perform additional composting to yield liquid fertilizer. This study focuses on the effect of weight and composting time on concentration of carbon compound, N, P, K elements and carbon compound/N ratio. It also studies the liquid organic fertilizer for growing of tomato plants . Ten day of composting shows most effective result for the mixture of rumenbrown sugar with weight ratio 1:1 and ratio of chicken inside-brown sugar 1:1. However, the resulted liquid is not yet qualified as a liquid organic fertilizer because the total organic compound (TOC)/N ratio greater than 25. Continued composting to greater weight ratio of chicken inside-brown sugar and longer composting time can decrease total organic compound (TOC)/N ratio to less than 25, so that matchs qualification as a liquid organic fertilizer. Liquid fertilizers doesn�t show clear effect on the hight of plant and the number of leaves.
