Abstract

Biogas is a renewable energy which can be used as alternative fuel to replace fossil fuel such as oil and natural gas . Recently, diversification on the use of energy has increasingly become an important issue because the oil sources are depleting . Utilization of agricultural wastes for biogas production can minimize the consumption of commercial energy source such as kerosene as well as the use of firewood . Biogas is generated by the process of organic material digestion by certain anaerobe bacteria activity in aerobic digester . Anaerobic digestion process is basically carried out in three steps i.e. hydrolysis, acidogenic and metanogenic . Digestion process needs certain condition such as C : N ratio, temperature, acidity and also digester design . Most anaerobic digestions perform best at 32 - 35°C or at 50 - 55°C, and pH 6 .8 - 8 . At these temperatures, the digestion process essentially converts organic matter in the present of water into gaseous energy . Generally, biogas consists of methane about 60 - 70% and yield about 1,000 British Thermal Unit/ft 3 or 252 Kcal/0.028 m3 when burned . In several developing countries, as well as in Europe and the United States, biogas has been commonly used as a subtitute environmental friendly energy . Meanwhile, potentially Indonesia has abundant potential of biomass waste, however biogas has not been used maximally . Key words : Biogas, renewal energy, anaerobic

Abstract

The ban against using antibiotics has led to increase the use of alternative additive substances as antibiotic. The alternative additives that can be used as antibiotic are probiotic and prebiotic. Both components can be used separately or together as synbiotic. Probiotic and prebiotic can modulate the ecosytem of intestinal microflora that is potential to affect the health and performance of host. Probiotic and prebiotic have been widely used abroad because of their positive effects, but the research and the use of these components in Indonesia are limited, eventhough abundance of raw material that can be used are available. The research dealing with probiotic and prebiotic as additive is necessary to be improved to obtain the efficient and practical production method, which can be implemented to give an economic impact on livestock industry. Key words: Probiotic, prebiotic, additive, livestock
