Using non-renewable energy for the engine also releases large amounts of pollutants results from combustion products was other issues to the environment. The decline of non-renewable energy sources, such as natural gas, fossil fuel, and petroleum made the world increase the production of alternative fuels like waste-derived fuels. Recently, biodiesel production developed from edible oil to cover the depilation of non-renewable energy supply. But it has also become a significant challenge for food security. Therefore, finding other potential opportunities for lipid extraction is crucial. Algae and sludge conversion presented by recent studies seem to be a promising method. The paper presents the extraction and optimization of lipids from blended sludge and algae for biodiesel production. The procedure of the study was a characterization of algal and sludge wastes, the extraction of the lipid component by Soxhlet extraction, and the parameters optimization for maximum oil yield obtain. Temperature, extraction time, and solvents were the basic factor affect oil extraction yield. In the optimization 80 temperature, 6hrs time and hexane solvent results in 61% oil extraction yield which maximum point. Algae and wastewater sludge high potential of lipid and can be substitute edible oil supplies for biodiesel production.","PeriodicalId":36269,"journal":{"name":"Production Engineering Archives","volume":"27 1","pages":"203 - 211"},"PeriodicalIF":2.3,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47679955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The high demand for transport services, even in the time of the Covid-19 pandemic, and the introduction of new regulations by the European Union authorities mean that these enterprises have to increase their efforts on competitive foreign markets. Telematics systems play a crucial role in this battle as they enable the acquisition and processing of data characterizing processes in road transport. In this article, the author undertakes the issue of logistic indicators in theoretical frames, as well as their classification and characteristics as the main source of information about processes. This is followed by the analysis of data obtained from a transport company using a telematics system to manage transport processes in the context of ensuring the quality of services. The aim of the study is to demonstrate the significance of selected logistics indicators in terms of improving the quality of transport services. Statistical analysis is used to study the relationships and impact of individual measures in 2019-2020 as a forecasting tool. The result of the research is finding an appropriate link between the measures and using this knowledge as an opportunity to improve the quality of services.","PeriodicalId":36269,"journal":{"name":"Production Engineering Archives","volume":"27 1","pages":"176 - 183"},"PeriodicalIF":2.3,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46009138","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The production involves impregnation of catalyst followed by thermal treatment. Both XRD and Raman spectroscopy allowed the observation of microstructural change of the prepared sample at temperature ranging from 1000°C to 1400°C using Ferum catalyst. From XRD pattern it can be observed that as graphitization temperature increased, the degree of graphitization also increased. Overall sample prepared at higher temperature 1400°C shows a higher degree of graphitization. PKS sample graphitized at 1400°C with the aid of Ferum catalyst shows a sharp intensified peak at 2θ = 26.5° reflecting formation of highly crystalline graphite structure. Raman spectrum also suggests similar results to XRD in which PKS-1400 shows the presence of large amount of graphitic structure as the value of (Id/Ig) ratio is lower than in other samples. HRTEM analysis visibly shows define lattice fringe, which further confirms the structural transformation from amorphous to highly ordered graphitic carbon structure. Overall, good quality graphitic carbon structure from Palm Kernel shell was succesfully synthesised via utilization of PKS, Ferum catalsyt and heat treatment method.","PeriodicalId":36269,"journal":{"name":"Production Engineering Archives","volume":"27 1","pages":"124 - 129"},"PeriodicalIF":2.3,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46101191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the paper we presented all classical seven task of production management control. Also there is in the paper an analysis of main factors affecting production control in industrial organization. In the paper we analysed the problems connected with production control. Nowadays in the conditions of Industry 4.0 this is very important concept because the increasing level of digitalization of all industrial processes leads to possibility of detailed analysis of all processes and better level of control. Operation managers should have good level of knowledge about production control and especially quality control. They can use in this many new information tools like statistical methods and artificial intelligence. Especially we think that in the future many function of production control would be assisted by artificial intelligence.

The increase in ecological awareness of the Polish society contributes to the continuous growth of interest in green energy. However, many people haven’t been aware of the ecological, economic and energy benefits of photovoltaic installations yet, so the following analysis is made. The analysis concerns a photovoltaic installation with a capacity of 3.96 kWp located in Ościęciny near Włocławek. The photovoltaic installation consists of 11 monocrystalline panels with a power of 360 Wp, a 4 KTLM Sofar Solar inverter and other necessary components. The first part presents basic issues related to photovoltaic installations. Parameters related to the proper functioning of the photo-voltaic installation were replaced. The analysis of the literature will help to understand the essence of the proper functioning of the photovoltaic installation. In the practical part, an analysis of a selected home photovoltaic installation was carried out. Based on the available data, it has been calculated that the installation will have a payback period of over 9 years. The photovoltaic installation will produce approximately 3 582.61 kWh of electricity and will contribute to the reduction of 70 tons of carbon dioxide during the entire operation.","PeriodicalId":36269,"journal":{"name":"Production Engineering Archives","volume":"27 1","pages":"90 - 99"},"PeriodicalIF":2.3,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69533271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study was to determine the production potential of biodiesel, methane and electric energy of the largest parboiled rice industry in Rio Grande do Sul, located in the southern region of the country.
