Water hyacinth (Eichornia crassipes Solms) is one of the green plants that become weeds in the weters. Therefore, the plant will be used as an ingredient in the manufacture of compost. To speed up composting, it is necessary to add a starter. Starter used is derived from the blood of cows, rumen cows and banana cobs, because its existence is a waste that is not utilized for the environment. This study aims to determine the addition of starter type in improving the quality of compost from water hyacinth (Eichornia crassipes Solms).
The method used in this study is After Only Dsesign with 6 repetitions. There are 4 variations of treatment in this study. Composting water hyacinth (Eichornia crassipes Solms) without addition of starter (K), composting water hyacinth (Eichornia crassipes Solms) with cow blood (P1), water hyacinth (Eichornia crassipes Solms) with rumen cow (P2) and water hyacinth (Eichornia crassipes Solms) with a banana cobs (P3). The analysis of the results of the study using statistical test paired sample t-test and one way annova.
Based on the physical parameters, the compost produced by the K treatment shows brown color, odorless and clot. While the compost P1, P2 and P3 shows black, smelling soil and crumbs. Based on the chemical parameters, the compost produced from the four treatments K, P1, P2 and P3 showed C/N ratio of 7,53 ; 9,19 ; 16,70 ; 10,47.
Of the four treatment, compost with the addition of cow rumen starter has the fastest time in the degradation process that is 20 days by producing a good compost quality when viewed from physical and chemical parameters, therefore it need to apply to the plant to know the difference significantly.
