Abstract:
The success of corn agro-industry is influenced by the availability of fertilizers, especially of artificial fertilizers whose availability continues to decrease. The solution is to increase compost production through the use of wet/ dry stover (WS/DS), commercial/ traditional cattle waste (C/T CW) in EM4 solutions (5 ml/l and 10 ml/l). The purpose of this study was to obtain the formulation of compost making materials. Composting was done by mixing C/T CW, WS and DS with formulation material (Control; 1: 0: 3; 1: 1: 2; 1: 2: 1; 1: 3: 0), putting into polybags in a bucket covered, performing an anaerobic fermentation for 40 days, and checking and stirring once in three days. Compost is ripely characterized by a distinctive fermented aroma. The treatment of compost material formulation used a nonfactorial Completely Randomized Design Model (non-factorial CRDM). Parameters observed were yield, moisture content (oven), pH (potentiometry), P2O5 (spectrophotometry), K2O (AAS), organic C (
Gravimetric), N-total (Volumetric), C/N ratio. The results showed that EM4 performance of 10 ml/l of water was better than 5 ml/l of water which could speed up the composting process, K2-1: 0: 3 compost material formulation produced more compost in accordance with SNI quality standards with a yield of 30.86%, moisture content 28.92%, pH 5.97, P2O51.12%, K2O 2.01%, organic C 50.06%, N total 1.95% and C / N ratio 25.67.
