Abstract

Cow’s feces originated from farms dairy an organic waste that can causing an environmental pollutiontherefore need to be process to make something such as fertilizer using activators that help the decompositionprocess run faster. Activator used in this experiment is Stardec. Decomposition of cow’s feces becomingorganic fertilizer by mixing cow’s feces with Stardec activator. Ratio of cow’s feces weight (Metric Ton) byweight (Kilogram) of Stardec activator is 1:0; 1:1; 1:2; 1:3; 1:4. Thereafter, add the anorganic fertilizer(Urea, KCl, SP-36) and limestone to the mixture each about 2,5 kilograms after that cover the mixture withplastic wrap and make some holes with bamboo. The allowing the mixture for 3 weeks to make an analysis ontemperature and C/N ratio for 3 days. The experiment result shows that process of composition for 21 dayson Stardec with 10 kg weight to produce organic fertilizer consist about 15,23% organic carbon, 0,84% totalnitrogen, 18,13 C/N ratio. These result meet the quality standards set by the Minister of AgricultureNo.70/Permentan/SR.140/10/2011.

Abstract

Cow's excrements originated from slaughterhouse is an organic waste that can damage the environmenttherefore need to be process to make something such as fertilizer using activators that help thedecomposition process run faster. Activator used in this experiment is Effective Microorganism 4.Decomposition of cow’s excrements becoming organic fertilizer by mixing cow’s excrements with EffectiveMicroorganism 4 activator. Ratio of cow’s excrements weight (Metric Ton) by volume (Liter) of EffectiveMicroorganism 4 activator is 1:0; 1:1; 1:2; 1:3; 1:4. Thereafter, add the anorganic fertilizer (Urea, KCl,SP-36) and limestone to the mixture each about 2,5 kilograms after that cover the mixture with plastic wrapand make some holes with bamboo. The experiment result for this study using Effective Microorganism 4activator by adding 4 liter in the decomposition process for 18-21 days to produce organic fertilizer consistabout 15,01% organic carbon, 0,87% total nitrogen, 17,25 C/N ratio. These result meet the qualitystandards set by the Minister of Agriculture No.70/Permentan/SR.140/10/2011.

Abstract

Bioethanol made from lignocellulosic biomass is currently being developed. The main obstacle production of bioethanol from lignocellulosic materials is at the stage of the process of hydrolysis of lignocellulosic material to form sugars. Enzymatic hydrolysis using cellulase enzyme is plagued by an expensive price. In the previous studies have been carried out production of Trichoderma reesei cellulase enzymes,in this research conducted using Aspergillus niger by solid substrate fermentation method. Enzyme production studies conducted in two stages in, there were in the aerated Erlenmeyer flask and rotary drum fermenter (RDF). The results showed that the production of cellulase enzymes in the rice straw substrate has resulted in enzyme activity similar to sawdust from the wood sengon. Water content effect on enzyme activity. The best results were obtained on a substrate of rice straw at 60% moisture content and fermentation time of 6 days, the CMC-ase activity of FP-ase was 0.00229 and 0.00095U /ml respectivelly. The best results in sengon sawdust substrate is reached at 70% moisture content and fermentation time of 7 days, obtained CMC-ase and FP-ase activity 0.00257 and 0.00133 U/ml respectivelly. Productivity of the enzyme in the RDF is similar to the Erlenmeyer flask. At RDF, obtained CMC-ase and FP-ase of 0.00243 and 0.00105 U / ml for rice straw substrate, and 0.00224 and 0.00125 U / ml for sengon sawdust substrate.
