Food leftover and solid kitchen waste disposed on open land surface, consequences different problems like air pollution, human health problem, ground water pollution, disturbance of ecosystem etc. For this problem recovering leftover food and solid kitchen waste for biogas production is critical solution. Sustainable energy production is the current issue for non renewable energy crises. The quality biogas determined by factors (temperature, PH, retention time and substrates). The method that determines the quality and quantity of biogas: first Data (leftover food and solid kitchen waste) was collected, characterize, then the slurry solution where prepared. At pH of solution (slurry) adjusted 4.6 – 6.3, at the temperature of Mesophilic range 25 – 40°C). The biogas production procedure: Hydrolysis - Acidogenesis – Acetogenesis – Methanogenesis. the volumew of biogas and CH4 maximization is the objective of this syudies. depending on experiental result output optimization model equation was developed using design expert, central composite method. In this experimental design With the retention time of 29 days, the quality is tested at an different alternatives. From the substrate source of leftover food and solid kitchen wastes, using experimental input, optimization result output from design expert: 63.3% CH4, 27.9% CO2, 0.316% O2 and 3.35L biogas quality and quantity respectively produced, from 1.75L of proportional slurry substrate prepared, at temperature 26.1°C and pH 5.51.
