Abstract

Abstract: In this biogas research from water hyacinth, we are using Central Composite Design and full factorial design. Enzyme (X1), C/N ratio (X2) and total solid (X3) is three experimental variables were selected as controlled factors. Performed on a laboratory scale and at room temperature with 16 runs for 60 days measured every two days. The variables were set at 3-9% for Enzyme concentration, C/N at between 20-50, and concentration of TS between 5-15% (LAD condition). Based on the research that has been done, the optimum conditions for the biogas production process from water hyacinth in Liquid State Anaerobic Digestion (LAD) conditions use Response Surface Methodology (RSM) in the variable range are the C/N ratio 30-40, 6% enzyme, and for TS was not significant factor. Following the run in the central composite experimental design, these values correspond to run number 10 with variable C/N ratio 35, enzyme 6% and TS 1.59% with biogas production 202.51 mL/g TS.
