ERP Systems Enhanced with RFID Technology in Furniture Industry

RFID technology is being widely used in most areas that are supported by ERP systems. With the help of RFID tags and readers placed at various locations throughout a furniture company, the presence of various objects in the factory can be monitored in real time. Readers receiving information from RFID tags can transmit it directly into the system and create databases or initiate business processes. The basic resources that can be tracked using RFID are human and machine resources as well as warehoused inventories, spare parts, tools, semi-finished and finished products. The only condition that must be met by the tracked object is that it can be tagged. The furniture industry is continuously growing. With factories expanding to tens of thousands of square metres and employing thousands of workers, knowledge of who or what is where at any given time is very important for optimising plant operations. Being able to gain this knowledge in real time is very useful and saves a lot of resources over the long term. Monitoring of resources in an ERP system using RFID technology is very popular nowadays. The improvement of the implemented solution leads to an ever increasing degree of control. However, it is important to maintain it at an optimal level, because otherwise it may unnecessarily disturb employees in their daily duties or generate more work for them without returning a measurable benefit.

ANALISIS PENURUNAN SISTEM KOMPRESOR PADA PEMBANGKIT PT. INDOCEMENT TUNGGAL PRAKARSA, TBK. KALIMANTAN SELATAN

Supply of compressed air has an important role in continuity of operation power plant, failures that occur in operation of engine in this unit can affect all plant operations that can result in decreased production levels. To determine the magnitude of loss of pressure or energy loss lost in pressurized air piping system at plant located in PT. Indocement Tunggal Prakarsa, Tbk. Tarjun Plant-12. Evaluation of pressure reduction losses in the air system is focused on losses caused by system leakage and pressure drops in the distribution lines caused by several factors including friction in straight pipes, bends, fittings, reducers and existing components, and knowing the loss of costs due to compressor pressure drop. The pressure drop in the pipe is very dependent on pipe diameter, besides distance and supporting components on piping system also affect the pressure drop. Based on calculation, there was a decrease in pressure of 1603660,895 Pa, from pressure drop caused by friction of straight pipe and connection and actual condition of pipe surface which was likely to have been corroded, making surface rough. system decline that occurred in the compressor resulted in a loss of operational costs of 5,760,451 rupiah / week.

The subject of the considerations contained in the article is the analysis of selected issues related to the legal regulation regarding the civil law obligation to prevent damage that may result from mining plant operations. It is about the regulations contained in the Act of June 9, 2011, Geological and Mining Law, and to a certain extent also in the Act of April 23, 1964, the Civil Code. This analysis includes not only theoretical considerations, but also refers to the practice of applying the law. It contains a discussion and a critical assessment of the Supreme Court’s judgment of February 20, 2018.

Treatment of PCBs Contaminated Soil Via Aerobic Vermicomposting Process Amended with Biological Sewage Sludge

Background: During power plant operations, significant amounts of (PCBs)-contaminated soil are generated. PCBs enter the environment in various forms, causing toxicity in humans and other living organisms. Various technologies are used to remove PCBs from contaminated soils and sediments. Objectives: Bioremediation is an environmentally friendly method to improve areas infected with PCBs. In this study, to decontaminate PCB-contaminated soil, the effect of biological sludge in contaminated soil on the removal of PCBs was investigated in a vermicomposting process at different mix ratios. Methods: Mixtures of PCB-contaminated soil and biological sludge were prepared in sample containers at different mix ratios, and then, earthworms were added. Over 80 days, besides the reduction of PCBs, pH, volatile solid content, and fixed solid content changes were also examined. Results: The highest reduction in PCBs (47.4%) was reported in pilot D at a contaminated soil-to-biological sludge volume ratio of 1:4. Moreover, in the same pilot, the pH level decreased from 7.9 to 7.2, indicating a further decline compared to other pilots, attributed to the further reduction of volatile solids. The highest reduction in volatile solids occurred in pilot D, decreasing from 74.8% at the beginning of the experiment to 42.9% at the end. The largest amount of mineralization also occurred in the same pilot. Conclusions: In this study, it was found that Eisenia fetida worms, along with microorganisms in the biological sludge, could function properly at all volume ratios of contaminated soil to biological sludge and could purify contaminants in a vermicomposting process.
