“…Temperature Generally, there are three temperatures in the anaerobic digestion, i.e. pyschrophilic (10-25°C), mesophilic (25-45°C), and thermophilic (45-65°C) [47]. Lower temperatures during the process will reduce methanogen activity.…”

“…Generally SS-AD can be operated under mesophilic conditions with temperatures between 20-45 ° C or thermophilic conditions at temperatures of 45-65 °C [16]. At low temperatures, microorganisms in the fermentation process will produce fatty acids and alcohols because the methanogenic microorganisms are deactivated and thus cannot digest all the fermentation products that are formed.…”

Abstract. An effort to obtain alternative energy is still interesting subject to be studied, especially production of biogas from agriculture waste. This paper was an overview of the latest development of biogas researches from rice husk waste by Solid State Anaerobic Digestion (SSAD). The main obstacle of biogas production from rice husk waste was the lignin content which is very difficult degraded by microbes. Various pretreatments have been conducted, either physically, chemically as well as biologically. The SSAD method was an attractive option because of the low water content of rice husk waste. The biogas yield by SSAD method gave more attractive result compared to Liquid Anaerobic Digestion (LAD) method. Various studies were still conducted in batch mode laboratory scale and also has not found optimum operating conditions. Research on a larger scale such as bench and pilot scale with continuous systems will be an increase trend in the future research.

Abstract-In this study, we investigated the use of laboratory batch anaerobic digester to derive kinetics parameters for anaerobic co-digestion of cow dung and grass clippings. The Carbon/Nitrogen (C/N) ratio of cow dung was found to be 17.17 and grass clippings to be 20.54. Through co-digestion, the C/N ratio settled at 19.08. Laboratory experimental data from 10 litres batch anaerobic digester operating at mesophilic temperature of 37 0 C and pH of 6.9 was used to derive parameters for Modified Gompertz model. The actual biogas yield was found to be 4370 ml/g COD. In the model of biogas production prediction, the kinetics constants of A (ml/g COD), μ (ml/g COD. day), λ (day) were 4319.20, 939.71, 1.91 respectively with coefficient of determination (R 2 ) of 0.996.
