Abstract
This research aimed to determine the pH, Water Content, C-Organic, and C/N of Goat ManureBased Compost Fertilizer with the Addition of Water Hyacinth and Effective Microorganisms. The method used was an experimental with 4 treatments and 3 repetitions, these is only for making composite samples for laboratory analysis. Data will be analyzed descriptively for the variables. The treatments given were T0=100% goat feces, T1=85% goat feces+15% water hyacinth, T2=80% goat feces+20% water hyacinth, and T3=75% goat feces+25% water hyacinth. The results showed that the pH of the compost for each treatment ranged from 7-8. Water content 44.30%-57.90%. C-Organic content 12.04%-15.36%. The N-Total content 2.16-3.01%. C/N ratio values 4.5-7.1. Based on research results, adding water hyacinth as a basic ingredient for making compost fertilizer can increase the pH value, water content and total N. The addition of water hyacinth can reduce the value of organic C/N content and the value of C/N ratio. The addition of water hyacinth does not meet the standards of Minister of Agriculture Regulation Number 261 of 2019 concerning several contents such as water content and organic C, so the addition is 15%, 20% and 25% need to be studied further.
