Abstract

The important parameters needed for process and digester design in biogasproduction are kinetic constants. This research will study these constants for biogasproduction from cow manure. The study is based on anaerobic bacterias cell growthkinetic with simplifying the organic degradation to biogas in one main step that is done bymathanogenic bacterias, and the value of μg is represented by Monod Equation. From thisresearch it is obtained the value of kinetic constant for cow manure biogas productioni.e. , , CH VS Y 4 / , CO VS Y 2 / , VS X Y / , CH X Y 4 / and CO X Y 2 / respectively of 0,0433 day-1 to0,1386 day-1, 21,23 mg/L, 478,42 L CH4/kg VS, 438,02 L CO2/kg VS, 30,9278 g VS/g sel,14,7965 L CH4/g cell, dan 13,5470 L CO2/g cell.

Abstract

Biogas production from soybean curd industry waste water was studied in laboratory scale to improve the application of anaerobic digestion process. The problem with the soybean curd waste water was the fact that it does not sufficiently contain anaerobic microorganisms required in biogas production. Therefore, it is necessary to add a well-developed population of anaerobic microorganisms to accelerate the start-up of the anerobic digestion. This research was aimed to verify the influence of the addition of active digester effluent into the soybean curd waste water batches in an anaerobic digestion process. Batch experiments were done in two digesters. The first digester was only fed with soybean curd waste water while the second digester was fed with soybean curd waste water and active digester effluent from a digester processing cow manure which was very rich in anaerobic microorganism consortium. The results indicated that soybean curd industry waste water did not contain methanogenic bacteria but there existed some acidogenic bacteria. The addition of active digester effluent accelerated the anaerobic digestion start-up and directed the process pathway towards methanogenic process so that more methane was obtained. The high methane content obtained (more than 64% volume) was very potential for power generation. The capacity of soybean curd industry must be as high as 697.13 kg soybean per day to generate the electric energy of 8.4 kWh.

Abstract

Biogas is a renewable energy derived from the degradation of organic materials, such as agricultural waste, livestock waste, and others. Several Qur'anic verses in Islam explicitly support the wise and effective utilization of natural resources; this includes the concept of sustainability and sustainable management of resources. “Eat [therefrom] and pasture your livestock. Indeed, in that are signs for those of intelligence.” is an example of biogas management' relationship with the Qur'an (QS. Thaha: 54). Biogas made from livestock manure is an example of wise resource utilization and is in line with Islamic teachings about not wasting natural potential. Using biogas as a renewable energy source reflects the concept of sustainability (istidamiyyah), which is highly encouraged in Islam. The use of biogas reduces the use of fossil fuels, reuses organic waste that normally pollutes the environment, and reduces greenhouse gas emissions. Biogas generation is closely related to Islamic teachings on environmental conservation, effective resource management, and the role of humans as khalifah on earth. By utilizing renewable energy such as biogas, Muslims can apply the teachings of the Qur'an to protect the Earth, prevent damage, and maintain the balance of the ecosystem.
