Effect of Variations in the Composition of Cow's Rumen and Straw on the Quality of Organic Fertilizer

Organic fertilizer raw materials that can be obtained naturally and are rich in nutrients found animal slaughtering activities. Slaughtering activities generally produce waste manure, which used as material for organic fertilizer. This study aimed to investigate the effect of composition on quality fertilizers. The parameters studied were C/N, P, K, pH, temperature. four reactors with each reactor volume 120 L exact weight 20 kg. Variations rumen Madura cattle straw this RK (100% cow rumen), R1: (65% rumen: 35% straw), R2: (50% 50% R3: (35% 65% straw). composting process is carried out 50 days. Analysis using SNI 2803: 2010. results showed differences content impacted generated R3 cattle: straw) C/N ratio = 13.25, P 6.12%, K 7.55%, pH 6.82, Temperature 33.7oC variations fulfill criteria Regulation Minister Agriculture Number 70 2011.
