Evaluation of Potency Spent Coffee Grounds for Make Black Compost
The aim for this research is to make black compost from spent coffee grounds (SCG). The content of hemicellulose and lignin from SCG were 37.28% and 22.45%. For mineral content, Potassium (3 g/kg) is the most abundant element in spent coffee ground, followed by calcium (1.23 g/kg), magnesium (1.11 g...

| Summary: | The aim for this research is to make black compost from spent coffee grounds (SCG). The content of hemicellulose and lignin from SCG were 37.28% and 22.45%. For mineral content, Potassium (3 g/kg) is the most abundant element in spent coffee ground, followed by calcium (1.23 g/kg), magnesium (1.11 g/kg), phosphorus (0.89 g/kg) and natrium (0.7 g/kg). SCG also contains Carbon and Nitrogen ratios 1:19.5 which approaches the C / N ratio of the soil 1: 20. Composting process in aerobic condition for 2 months using Fungi, Bacillus and Lactic Acid Bacteria activator, produce black compost with good characteristic for plant and soil, such as C/N ratio under 1:10 and pH around 6 to 9. |
