The Impact

The study evaluated the impact of fermentation with Bacillus sp. on the nutritional quality of soybean meal (SBM) and the changes of bacterial community structure during fermentation. High protease-producing strains were screened to degrade SBM macromolecular protein and anti-nutritional factors (ANFs). Unsterilized SBM then underwent an anaerobic solid-state fermentation method to evaluate the effects of fermentation. Results showed that for the nine high-producing protease strains that were screened, acid-soluble protein (ASP) contents in fermented SBM increased, with the highest value found to be 13.48%, which was fermented using strain N-11. N-11 was identified as Bacillus subtilis. N-11 fermentation reduced ANFs such as glycinin and β-conglycinin by 82.38 and 88.32%, respectively. During N-11 fermentation, the bacterial richness and diversity in SBM increased but not significantly. The high-yield protease strain B. subtilis N-11 selected in this experiment improved the nutritional quality of SBM through fermentation, and it can be used for industrial large-scale production.

Large Scale Production

Silver nanoparticles (Ag NPs) are the most frequently studied material with superiority as antibacterial that currently increasing the production of Ag NPs. Hence, feasibility study is needed for the development on the production of Ag NPs in industrial scale, especially in Indonesia and other developing countries. The chemical reduction with sodium citrate is used to produce Ag NPs. The purpose of this study is to analysis the prospect of large-scale industrial production in engineering perspective and economic evaluation. This study also gave recommendations for profitability of the production. Perspective of engineering in the production gave information about capability of large-scale production because the easy process and low-cost apparatuses of production can be done. Various economic parameters were used to completed the analysis. Then, the ideal condition to the worst issues of production was estimated to completed the calculation of economic evaluation by effects of raw materials. From this study, those all parameters gave positive result which mean it has good profitability. However, further analysis of strategies in sales and investment must be done in the future to developing the production of Ag NPs that promising in capability on large-scale production.

The chemical reduction of a wet colloidal suspension of graphene oxide is a cost-effective and adaptable method for large scale production of “quasi” graphene for a wide variety of optoelectronic applications. In this study, modified Hummers’ procedure was used to synthesize high quality graphene oxide at 50°C. This modified protocol thus eliminates the potentially hazardous second high-temperature step in Hummers’ method for the production of GO. Furthermore, the reduction of graphene oxide by lithium triethylborohydride is demonstrated for the first time. According to FT-IR, UV-Vis, TGA, Raman, SEM/EDS, and AFM results, the reduced graphene oxide (LiEt3BH-RGO) has properties comparable to other reduced graphene oxide products reported in the literature.

State Method

Spinel lithium titanate (Li4Ti5O12) materials were synthesized by a hydrolysis precipitation-assisted solid-state method in the temperature range from 600 to 900℃ for large-scale production. DSC/TGA, XRD and SEM were used to characterize the as-prepared samples. The optimum synthesis condition was examined in relation to the charge–discharge performance. It was found that when the dry hydrolysis precipitation precursor with 8% Li excess was calcined at 700–800℃ for 12 h in air, a pure Li4Ti5O12 phase was obtained. The as-obtained material has the best electrochemical performance due to its narrow size distribution and precise stoichiometry of the oxide.
