摘要：This study combines market waste (MW),yard waste (YW) and cow rumen (CR) as raw materials to obtain the optimum C/N ratio of compost raw materials.Composter consists of 6 variations,namely variation 1 (70% MW: 30% YW),variation 2 (60% MW: 20% YW: 20% CR),variation 3 (50% MW: 30% YW: 20% CR),variation 4 (40% MW: 40% YW: 20% CR),variation 5 (30% MW: 50% YW: 20% CR) and variation 6 (20% MW: 60% YW: 20% CR).This study aims to analyze the effect of variations in compost raw material composition so that the most optimum variation is obtained for the composting process.The method used was semi-aerobic composting.The results of observations on compost maturity for temperature,pH,texture,color and odor parameters have met SNI 19-7030-2004 standards with composting time of 12-21 days.The results of compost quality analysis including water content,organic C,nitrogen,C/N ratio,phosphorus,and potassium have not all variations fulfilled the SNI 19-7030-2004 standard,namely the value of the C/N ratio in variation 6 which exceeds the standard.Of the total compost as much as 3 liters,the solid compost yields of 0.5-1.25 liters and liquid compost from 0.05 to 1.5 liters were obtained.Based on the results of scoring on maturity,quality,and compost quantity,the best variation was found in variation 2.
