The methodology used was a bibliographic study, as research source were used: Internet documents, scientific articles available on scientific platforms and handouts for alcohol manufacture. The results were qualitative, being defined and approximated or researched by observation, fostering discussions about: ethanol production, alcoholic fermentation, microbial contamination, conditions that cause contamination, contaminating microorganisms, performance and forms of contamination control. Thus, through the comparative debate of the data, it is noted whether the control of factors such as: pH, temperature, osmotic pressure and °Brix; directly and indirectly influences the proliferation of microorganisms that brings harm to the fermentation and consequently to the fermentative yield. 2019-11-01T00:00:00Z https://ri.ufs.br/jspui/handle/riufs/12585 Título: Aplicação de roteirização por meio da pesquisa operacional para redução de custos uma empresa em Penedo-AL Autor(es): Silva, Diewelly Maria; Silva, Mayara do Nascimento Maurício; Ferreira, Thiago Pereira; Silva, Jeisiely da Cruz; Escarpini Filho, Romildo dos Santos Abstract: The objective of this work is to analyze the problems and restrictions that exist for choosing the best route for the owner of a snack bar in the municipality of Penedo / AL. Through this analysis, with the help of LINDO software to study the best route that reaches all points where the businesswoman must go, seeking optimization time, shorter distance, with this, lower fuel cost. Operational Research is a proposed tool for solving successive routing problems through a linear programming language development and Lindo. After applying the routing mathematical parameter one can see the efficiency in route optimization and with this the reduction in fuel costs. 2019-11-01T00:00:00Z https://ri.ufs.br/jspui/handle/riufs/12584 Título: Proposta de aplicação da metodologia 5S estudo de caso em uma empresa de refrigeração em Penedo-AL Autor(es): Silva, Diewelly Maria; Santos, Elenilson Rivando; Oliveira, Talia Farias Abstract: The 5S program methodology is considered as one of the main initial tools that are applied with the intention of acquiring greater efficiency in systems where a quality management system is sought. The objective of this work is to apply the 5S program as well as to analyze the organization of the workspace of a refrigerator maintenance company located in the city of Penedo, in the state of Alagoas, making a comparative study of all the proposed improvements according to the application of the 5 senses. Periodic visits were made to the enterprise with further development of the improvement proposals. The main suggestions for improvement are to change the layout and workstation, as well as a greater concern with the work safety of employees. As suggestions, they were passed on to management for later application in the production process. 2019-11-01T00:00:00Z https://ri.ufs.br/jspui/handle/riufs/12583 Título: Gestão da qualidade e controle microbiológico na fermentação etanólica: estudo de caso em uma usina sucroenergética Autor(es): Santos, Elenilson Rivando; Oliveira, Talia Farias; Silva, Diewelly Maria; Silva, Edriane Teixeira Abstract: Sugarcane is the main raw material for ethanol production and the efficiency of the fermentation process is directly linked to its quality. The objective of this paper is to analyze the laboratory routine on the control of biological contamination that can impair the quality of fermentation in a sugarcane plant. The follow-up of microbiological analyzes, in fermented must and treated yeast, was made daily and following the routine of the laboratory responsible for verifying production management and quality control. The study showed that the analyzed samples have characteristics that meet the quality standards of ethanol productivity, and also prove that the performance of these analyzes ensures the maintenance of the yeast volume used during the harvest, enabling a more cost effective, efficient process that does not affect the quality of the desired product. 2019-11-01T00:00:00Z
