The Face

Para sobreviverem à crise global as empresas necessitam adotar medidas de contenção dos gastos, sendo que as operações logísticas se apresentam como fundamental nesse processo, diante dos custos elevados com transporte rodoviário. Acrescenta-se que o principal fator para os altos custos são os preços dos combustíveis, o que remete a mudanças nos processos de transporte com o intuito de diminuir o consumo de combustível utilizado no transporte. O objetivo desta pesquisa é propor mudança no processo de transporte da cana-de-açúcar para redução do consumo de combustível. Para atingir os resultados, foram utilizados como processos metodológicos a pesquisa bibliográfica com consulta em livros, artigos científicos e dissertações, com o devido rigor científico, seguida de estudo de caso com abordagem quantitativa. Dessa forma, foi realizada a fundamentação teórica por meio da pesquisa bibliográfica para embasar o trabalho e, em seguida, desenvolvido o estudo de caso mediante pesquisa documental primária, para realizar um comparativo entre as quantidades de consumo de combustíveis utilizados no método convencional e os valores projetados em uma mudança no método de transporte. Contudo, após a realização do estudo, foi possível observar que, mesmo diante de uma economia estimada em 10% no consumo de combustíveis, haverá aumento nos custos em proporção inversa, no que tange à manutenção de equipamentos, o que revela uma projeção de economia estimada em 9% dos custos totais.   PROCESS ANALYSIS AT A SUGARCANE COMPANY FROM TRIÂNGULO MINEIRO: CASE STUDY TO REDUCE FUEL CONSUMPTION IN TRANSPORTATION SERVICE   ABSTRACT In order to survive the global crisis companies need to adopt some measures to lower costs since logistic operations are essential for this process in the face of high costs with road transportation. In addition, the main reason for the high cost is the heavy price of the fuel resulting in changes in the transportation process in order to increase its fuel consumption. This paper aims to suggest changes in the sugarcane transportation process to reduce fuel consumption.  Conducive to obtain such results, it was used as a methodology for the bibliographic review by using books, scientific articles, and dissertation, with due scientific rigor, followed by a study case with a quantitative approach. Therefore, carrying a theoretical ground out through bibliographic research to support the paper, and, followed by a case study through primary documental research, to compare fuel consumption quantity used for conventional methods and the projected values for a change in transportation. However, after this study had been carried out, it was possible to note that, even in the face of a reduction estimated at 10% for fuel consumption, there will be an increase in costs in inverse proportion, regarding equipment maintenance, which reveals a projection for an estimated reduction in 9% of the total costs.   Keywords: Logistic.

The Impact

ABSTRACTOptimisation of aircraft ground operations to reduce airport emissions can reduce resultant local air quality impacts. Single engine taxiing (SET), where only half of the installed number of engines are used for the majority of the taxi duration, offers the opportunity to reduce fuel consumption, and emissions of NOX, CO and HC. Using 3510 flight data records, this paper develops a model for SET operations and presents a case study of London Heathrow, where we show that SET is regularly implemented during taxi-in. The model predicts fuel consumption and pollutant emissions with greater accuracy than previous studies that used simplistic assumptions. Without SET during taxi-in, fuel consumption and pollutant emissions would increase by up to 50%. Reducing the time before SET is initiated to the 25th percentile of recorded values would reduce fuel consumption and pollutant emissions by 7–14%, respectively, relative to current operations. Future research should investigate the practicalities of reducing the time before SET initialisation so that additional benefits of reduced fuel loadings, which would decrease fuel consumption across the whole flight, can be achieved.

Sustainable development is a kind of development where the pace of technical development, the satiation of increasing supply and the raw materials and resources of the Earth are poised so that the rate of living and the opportunities of the future generations should not decline. For this reason, transportation systems must be developed and the effectiveness of transportation service must be increased while environmental pollution must be decreased or prevented. Vehicles are burning fuels inefficiently. There are two options of decreasing environmental impacts – one is to reduce fuel consumption while another is to do it in a more acceptable way increasing efficiency. There is justifiable demand put forward by the society to moderate environmental impacts caused by road transportation. This article deals with modelling the energetic utilisation of exhaust gas.

Negative Impacts

The growing number of motor vehicles in urban areas has generated negative impacts on costs for users and bus operators due to congestion and the increase in travel time. Furthermore, transport sector is a significant user of energy, especially fuel, and a great responsible for greenhouse emissions. In order to mitigate these externalities, transport companies try to incorporate into their processes innovative tools and best practices in management, like the so-called economic-driving. The economic-driving seeks to reduce fuel consumption, greenhouse emissions and operational costs. This paper aims to present the results of an economic-driving program implemented in a public transport bus company in Brazil, in the period of 2010-2016. The methodologies used were exploratory, descriptive and case study. The results showed a reduction of fuel consumption by 786.336 liters. The analysis of the consumption of brake linings in eleven buses, running the same itineraries by the same drivers, decreased 47.46%. Based on the Embrapa’s methodology for the calculation of greenhouse emissions the company stopped emitting 86,757.36 kilo grams of CO₂ in the atmosphere. In conclusion, the case study confirmed the feasibility of applying economic-driving strategies and the economic and social advantages with the program for the company.

Abstract. The paper examines the workload perceived by air traffic control officers (ATCOs) and pilots during continuous descent operations (CDOs), applying closed- and open-path procedures. CDOs reduce fuel consumption and noise emissions. Therefore, they are supported by airports as well as airlines. However, their use often depends on pilots asking for CDOs and controllers giving approval and directions. An adapted NASA Total Load Index (TLX) was used to measure the workload perception of ATCOs and pilots when applying CDOs at selected European airports. The main finding is that ATCOs’ workload increased when giving both closed- and open-path CDOs, which may have a negative impact on their willingness to apply CDOs. The main problem reported by pilots was insufficient distance-to-go information provided by ATCOs. The workload change is important when considering the use of CDOs.

The present phenomenon has clearly brought a change and the influence of the development of traditional music in Palembang society, if this is not carefully addressed, it will experience a shift, alienation and even lose its supporters. The rejung pesirah music group is one of the music groups that still maintains traditional arts in the people of Palembang. This study examines how the adaptation strategy of the rejung pesirah music group in dealing with changes and developments in Palembang society. For this reason, the approach used is cultural anthropology with qualitative case study research methods in Palembang. Data collection is done through observation, interviews and document studies that use triangulation techniques as the validation of the data, while for data analysis through content analysis and interactive models. The results showed that the adaptation strategy undertaken by the rejung pesirah music group was an act and creative ability and had a positive mindset, understanding in responding to changes and needs as an impulse to develop in the face of environmental change and development through learning processes and cultural modification, which resulted a creativity that is the creation of songs, musical arrangements, and musical instruments in the rejung pesirah music group.
