Understanding quality in manufacturing starts with defect identification and improvement finding. Reliability that influenced by equipment design or working methods or environment has led to concept of improvement with six sigma method and this has been absorbed in Indonesia industries as well. This article discusses about six sigma implementation in Indonesia from various business and industries. The method is to review research articles that are published within 2016-2020 with keyword DMAIC and six sigma. The results from 52 selected articles is obtained average 3.68 sigma value of Indonesia industries within year 2016-2020 with the least value 1.10 from crude palm oil refinery and the highest is 5.10 from bagging process of sugar refinery. However, six sigma application is not always satisfying concerning its suitability function, requirement of industries, culture, local regulation, and internal business concern, especially in terms of efficiency and cost. Future research is suggested utilizing industry 4.0 concept to enhance six sigma implementations.

The results of comparative experimental studies of the effect of various widely used surfactants, as well as sugar refinery waste - after yeast molasses and vinasse on the wettability of the interaction surface during the in-field pipeline transport of oils from fields in the southern region of Azerbaijan and can be successfully used, especially in winter, to regulate fluidity highly emulsion and low solidifying oils. It is shown that the addition of the considered reagents leads to an increase in the contact angle cosine. The effect of the proposed reagents on the fluidity of oil samples with bound and free water, the composition of aqueous solutions of various reagents, as well as the pH of solutions of these reagents on the fluidity of oil samples has been evaluated.

Newly-formed soils of wastewater disposal fields from two sugar refineries in forest-steppe zone (Kursk region, European Russia) were studied. Among factors of soil formation on sugar wastewater lagoons the geochemical influence of wastewater mixed with diluted filtration and transport-washing sludge stands out. We have revealed key physico-chemical and microbiological properties of such soils formed under different moisture regimes, substrates, vegetation, and duration of use. Compared to conditionally background soils (Luvic (Anthric) Chernozems), the newly formed soils show shift of pH values to alkaline ones, carbonation, increase of soil organic carbon, growth in mobile forms of phosphorus, potassium and nitrogen. Microflora in studied soils is identical in composition to background soils, but it differs significantly in structure. In soils formed in the decommissioned wastewater lagoons of an active sugar refinery, a higher number of bacteria with low participation of Micromycetes and Actinomycetes was noted, which indicates active destruction of organic matter. In soils of the recultivated and completely abandoned sugar wastewater lagoons indicated as Calcaric Someric Phaeozem, a higher number of Actinomycetes was noted than in the background soils.

Purpose This study aims to measure the intensity of innovation in the Brazilian food sector and compares it to other manufacturing sectors in the country. Design/methodology/approach The authors used economic and financial data provided by the annual survey of industry [Pesquisa Industrial Anual (PIAs), in Portuguese] and other supporting data provided by the survey of innovation [Pesquisa de Inovação (PINTEC), in Portuguese] and the classification of technology intensity (TI) proposed by the Organization for Economic Co-operation and Development. The authors subsequently applied the Malmquist index in addition to the data envelopment analysis to measure innovation. Findings The results reveal that the Brazilian food sector is classified as a sector with low TI and investment in research and development (R&D), which represents one of the lowest rates when compared to other sectors. Thus, the Brazilian food sector is far from achieving its full potential. Nevertheless, the authors noticed that the sugar refinery industry showed an evolution in its technology frontier and presented a frequency of innovation similar to the average of high-tech industries. Originality/value This study contributes to the debate on innovation in the food sector, emphasizing the need to accomplish higher investments in R&D to increase the productivity of the sector.

The subject of the research within the scope of this paper is integrated wired and wireless communication technologies in the process industry, with the aim of keeping up with the world trends in this field, and refers to the following activities. First, a brief overview of the historical development will be provided and the technical characteristics of the industrial protocols that have the greatest application in industrial communication networks will be described. Then, necessary steps to integrate wireless technology within an existing facility with wired devices already installed will be presented. At the end of this paper, the integration of wireless technologies in implementing industrial communication networks will be proposed, which will be verified by analysing the results obtained in a feasibility study for introducing an integrated network model in a real facility in a sugar refinery in Brčko.

Organic dust explosions were and are still today a critical issue in the food, pharmaceutical, and fine chemical industry. Materials such as flour, corn starch, sugar and APIs represent a cause of severe accidents. In this framework, we investigated a modified version of Recursive Operability Analysis−Incidental Sequence Diagrams (ROA–ISD), called ROA Plus−ISD, specifically tailored to describe industrial processes involving organic combustible dusts. Compared to more classical techniques such as Hazard and Operability (HazOp), ROA−ISD allows for a direct generation of fault trees, providing a useful tool to connect Qualitative with Quantitative Risk Analysis (QRA). ROA Plus−ISD is very similar to ROA−Cause Consequence Diagrams (CCD), which has already proven to be an effective tool to perform both risk assessment on existing plants and reconstructing already occurred accidents, given its logical structure and width of the application fields. In this work, we modified specific parts of the standard ROA−CCD method: (1) the Failure Mode and Operability Analysis (FMEA) database has been structured in order to retrieve the well-known explosion pentagon (for dusts) and all the instruments, devices, apparatuses and controllers typical of industries which process organic dusts; (2) a new comprehensive list of process variables has been compiled. In this way, it is possible to tailor the information required for the generation of the fault trees concerning top events involving mainly dust explosions and fires. This method has been implemented in order to reconstruct the dynamics of the February 2008 Imperial Sugar refinery plant accident (Port Wentworth, GA, USA). Results demonstrated the applicability of the enhanced method by highlighting the criticalities of the process already showed by a previously detailed reconstruction performed by the Chemical Safety Board.
