Abstract:
All forms of energy is very costly, however, renewable energy generally may cheaper, while fossil fuels is mostly more expensive. Integrated Bio-cycle Farming System (IBFS) is an alternative system which harmoniously combines agricultural sectors, and non-agricultural aspects, on landscape ecological management. The cycle of energy, carbon, water, nutrient, production, crop, money was managed to be has multifunction and multi-product (Food, Feed, Fuel, Fiber, Fertilizer, Pharmacy, Edutainment, Eco-tourism). The purpose of this paper is to examine the growth of bacterial cells and bio-hydrogen production by Enterobacter aerogenes bacteria from organic waste of cajuput leaves. A stirred tank bioreactor that will be used is Fed Batch, an engineering process to produce maximal bio-hydrogen. Engineering process is used to increase the speed of the hydrogen production process and the acquisitions of hydrogen gas results to be more effective and efficient. Fermentation and production of bio-hydrogen was optimized after 24 hours, with the highest at a substrate concentration of 20%. The hydrogen production has positive correlation with the number of E. aerogenes bacteria through a dark fermentation method, a non-photosynthetic process that can do at all day without sunlight.
