The article provides an overview of drugs based on buckthorn bark included in the State register of medicines of the Russian Federation and patented in recent years. The methods of quantitative determination of anthracenes-derived raw materials of buckthorn according to the state Pharmacopoeia of the Russian Federation XI and XIII editions and the European Pharmacopoeia are analyzed and presented in the comparative aspect. The main representatives of the anthracene-derived buckthorn are shown for a number of sources, taking into account modern phytochemical studies. The algorithm of development of a technique of spectrophotometric quantitative determination of anthracenes derivatives in buckthorn bark and extraction preparations from it is gradually presented. Studied and selected the optimal conditions of extraction: raw material grinding – 1 mm, extractant – 10% sodium hydroxide solution, the ratio of raw materials and extractant – 0.1 : 100, the extraction temperature in a water bath 100 °C, the duration of extraction – 30 minutes. The analytical maximum of 510 nm was established, a certified sample of frangul-emodin was used as a standard substance, and an experimental calculation of the specific absorption rate of frangul-emodin interaction products with an alkaline-ammonia mixture was presented. In the research we describe an optimized pharmacopoeial methodology, metrological characterizations and results of quantitative determination of the anthracene derivatives in aqueous and alcohol extracts based on the buckthorn bark. The content of the amount of anthracenes in the samples of raw materials of five domestic producers. The content varies from 4.35 to 4.85%.

Abstract This study discusses the use of fly ash waste from coal burning on the manufacture of PCC (Portland composite cement) at PT. XYZ Lampung. The purpose of this research is to look at the technical studies and the efficiency of raw materials in the use of fly ash in cement making, in this case PCC cement (Portland Composite Cement). The steps taken in analyzing the data in this study were viewed from a technical aspect by means of a physical test, namely the cement compressive strength test at the age of 3 days, 7 days, and 28 days using the Compression Testing Machine. This test was conducted to see the comparison of the compressive strength of PCC cement using limestone and fly ash as raw materials, then calculate the difference in raw material costs in the year before and after the replacement of limestone with fly ash. The results showed that cement with the addition of fly ash after 3 days, 7 days and 28 days had an increased compressive strength value, which increased 21.69%, 16.07% and 8.05% respectively of the compressive strength of cement using limestone. The use of fly ash as a substitute for limestone has an effect on the cost of raw materials, where the difference between the cost of raw materials in 2019 and the cost of raw materials in 2018 is Rp. 39,440,952,074.

Increasing Demand

The increasing demand for zinc and a range of zinc-related metals (for example: lead; indium; tin; cadmium; and copper) in the Russian Federation cannot be satisfied by the existing production plants due to the lack of raw materials. At the same time, ferrous and non-ferrous metallurgy and the chemical industry have accumulated hundreds of millions of tons of zinc wastes (falling into the hazard categories 2 to 4), the processing of which could not only make up the raw material base, but also improve the environmental situation. In the world, over 85% of ferrous dust is recycled using the Waelz process. The Waeltz process is used for distilling separation of elements under reducing conditions. In this study, a block diagram for production of the following elements from industrial wastes is proposed: zinc, cadmium and indium in form of massive metals; zinc and indium in the form of fine powders; and clinker as a raw material for cement production. The technical and scientific details of this new process have been patented in the Russian Federation and abroad. For the first time, the following operations have been implemented with the use of large-sized Waelz kilns: vapour-oxidized Waeltz treatment of polymetallic wastes; recycling of heat from gases and solid products with generation of process fumes; and implementation of alternative flux (dolomite) and alternative fuel (petroleum coke). Keywords: Waelz process, industrial wastes, heat recycling, vapour-oxidized Waelz processing

In the manufacturing process Bus and Mini Bus, a lot of the raw materials required. Raw materials are stored at many warehouses (especially on Body PT. XYZ Malang). Materials / goods are highly vulnerable to lost or stolen. The most influential factor in it is the counting system inventory / materials and administration. These changes will have an impact on the process of goods more accurate calculation based on the demand of production. Losses will have a greater likelihood of being used if the system can not address the calculation of the goods/raw materials better.And administration system that can cope with the calculation of the goods/raw materials are better here is a system that can calculate expenditures for production based on the incoming bill alone, and can calculate the receipt of goods in accordance with the letter received by the supplier. The system can also provide reports based on existing transactions during a certain period.With the inventory system and the administration is then the difference between the goods that previously occurred can be minimized and raw material inventory accounting system can work better.

The Difference

Currently, the use of alternative fuels and raw materials (AFR) in the cement industry is very attractive. This is driven by demands for environmental sustainability and the efficiency of fuel and raw material costs. One of the materials that can be used as AFR is sludge oil. However, it needs to be ensured that the chlorine content in the sludge oil does not exceed the threshold so that it does not have a negative impact during the cement production process. It is known that if the chlorine content is more than the threshold, it can cause blocking or clogging of the separator and the kiln. This study aims to determine the performance of the Jena Multi EA 4000 instrument in determining the chlorine content in sludge oil quickly and accurately. Analytic Jena Multi EA 4000 is an Atomic Absorption Spectrometers (AAS) instrument that can be used for analysis of samples in the form of solids or slurries containing chlorine. As validation of the resulting analysis, the wet method is used, which as usual, to determine chlorine levels. From the statistic analysis, namely the F-test and T-test, We found that F-count equal to 0.0080 and F-table equal to 4.2839. it shows that F-count < F-table, indicating the difference in the variance of the two methods H0: s12 = s22 is accepted because there is no difference to the variability of these two tests and the value of T-count = -3.9717 and T-table = 2.1788 so that T-count <T-table is accepted because there is no difference in the average accuracy of the two methods H0: M1 = M2.
