ANALISA KARAKTERISTIK PUPUK KOMPOS BERBAHAN BATANG PISANG

Soil as a place to grow plants must have the enough nutrient to support the plant growth. The use of inorganic fertilizers continuously can caused decreasing the soil fertility and soil organic matters, so if not fixed immediately that land no longer able to produce on the optimum level and sustainable. The solution to overcome this problem is the addition of organic matter . Compost made from banana stems can be an alternative option that can aim to minimized the waste of unused banana stems. Organic materials that do not decompose completely will cause harmful effects. Therefore the government made Peraturan Menteri Pertanian No. 70/Permentan/SR.140/10/2011. The rules drawn up to regulate product quality compost so as to protect consumers and prevent environmental pollution. This study aims to investigate the characteristics of compost made from banana stems . Each parameter will be tested and compared with the minimum technical requirements of solid organic fertilizer contained in Peraturan Menteri Pertanian No. 70/Permentan/SR.140/10/2011. The result showed that compost made from banana stem has a quality that is in accordance with the quality of the minimum technical requirements Solid Organic Fertilizer Permentan Nomor 70/Permentan/SR.140/10/2011 includes parameters C-organic , C / N ratio , pH H2O , ( N + P2O5 + K2O ) , Fe total , Fe available , Mn total , Zn total, Pb total, Cd total, Microbial contaminants and Microbial Functional ( fastening N and Solvents P)
