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. |
