Abstract
The waste that enters the Loka Bhakti Reduce Reuse Recycle Solid Waste Treatment Facility is 12 m3/day consisting of composted and non-composted solid waste. This study aims to analyze the effect of processing composted solid waste into compost and the effect of leachate and rice washing water on the length of time for composting and compost quality. The waste treatment process uses the windrow composting method, lasting for four weeks. The independent and dependent variables were used with statistical tests using One Way ANOVA. The test results showed that the quality of compost with water content in treatment A was 53.51% or less than treatment B, which had 59.64% water content. The value of C-Organic compost in treatment A was 14.72%, and in treatment B was 11.67%. The value of N-Organic in treatment A was 0.93%, while in treatment B, it was 1.24%. The value of the C/N ratio in treatment A was greater than in treatment B, which was 15.52% > 11.77%. Phosphorus and potassium values in treatment A were greater than treatment B with a value of 0.36% > 0.31% for the phosphorus value and 1.18% > 1.01% for the compost potassium value. Statistical tests obtained hypothetical values on water content, C-Organic, N-Organic, C/N ratio, phosphorus and potassium <α- 0.05.
