PEMANFAATAN ECENG GONDOK (Eichornia crassipes) DAN PUPUK KANDANG KAMBING SEBAGAI BAHAN BAKU AMELIORAN ORGANIK
An experiment was conducted to determine the potential of goat manure and water hyacinth plants (Eichornia crassipes) as a source of organic material (ameliorant) to improve the quality of agricultural land. Water hyacinth plants and goat manure are used as raw material for making ameliorants with various compositions, namely: 100% goat manure, 75% goat manure + 25% goiter, 50% goat manure + 50% water hyacinth, 25% manure goat + 75% water hyacinth, and 100% water hyacinth which is brooded with a time variation of 2 weeks, 4 weeks, 6 weeks and 8 weeks. The results showed that ameliorant with a high composition of goat manure had better physical quality than ameliorant which was dominated by water hyacinth. The chemical analysis showed the levels of macro nutrients (N + P2O5 + K2O) in the treatment 75% goat manure + 25% water hyacinth in 4 weeks of composting fulfilled the standard solid organic fertilizer required by Regulation of the Minister of Agriculture No. 70 of 2011 which is above 4%, while the treatment of 100% goat manure only meets the standard soil improvement material because the levels of macro nutrients (N + P2O5 + K2O) are less than 4%.
