The purpose of the implementation of this research is to find the effectiveness of supplies raw materials, the method of analysis data used in the square is the smallest trend for planning raw materials and controling supplies use method of economic order quantity (EOQ) analyze reorder point. Analysis reorder point and safety stock. And analyzes efficiency cost of raw materials. Forecasting raw materials years 20x7 according to the smallest trend, cloth and dakron happened the difference is greater than of the target needed (according to a company); controling supplies raw materials with the methods eoq in 20x7 more effective than reservations raw materials cloth and dakron and more efficient than cost raw materials. The company should review the policy of forecasting raw material supplies that had been undertaken and make planning supplies the raw material that more accurate using the firm’s historical data and not only targeting the output production next year, so that machines production can be optimized. Considering the use of control supplies with the methods economic order quantity to companies, so this analysis can determine material reservations, supplies safety, maximum supplies to avoid the risk of running out of raw materials, because the companies often happened less dressed up a result of reservations that time is inaccurate, the lack of safety stock and the deferred the delivery of goods which often disturb the production process, by this method can prevent these things, so that the production process can run smoothly and minimize the cost of raw materials supplies.

The Added Value of Processed Red Ginger Product at UD. VisionBali Herbal Indonesia, DenpasarThis research aimed to determine the added value of red ginger as an herbal drink in one production process and to determine the level of profits earned by the company in the red ginger processing in one production process. Determination of the study area was done purposively and the analytical methods used was the method of added value calculation, i.e. the product value is deducted by the value of raw materials and other supporting materials.It can be concluded from the result of the research that the added value of the red ginger processing business obtained in one production process is Rp. 84.600,00/kg. The added value is obtained from the deduction of the value of the product/output of Rp. 175.000,00/kg with the cost of raw material (input prices) Rp. 25.000,00/kg and the contribution of the cost of other inputs of Rp. 65.400,00/kg. It was also found that the profits gained by the manufacturer from the processed red ginger into herbal drink in one production process was Rp. 200.954,06. The suggestion that can be given to the company is to put more attention in the details of its production costs so as not to result in a low ratio of added value and further to improve the marketing of the products, so that people are interested in re-use of herbal medicine that is free of chemical components.

Attainment of accuracy in raw materials mix for production processes has been the major problem in many production organizations in developing countries. Effects of unequal proportions of material required for a production process are not fully considered in the past studies. This study modeled the raw material requirements in a production process using proportionality based mixed linear programming approach. The objective was to find optimal mix of raw materials for the production of a unit tonnage of a product. The performance of the model was tested by comparing it with alternatively formulated model based on conventional material mix. This model was tested using a cement production system from which blasted limestone, crushed limestone; raw meal, gypsum, red alluvium, clinker and coal were used as raw materials. The conventional method of mixing materials led to 50 % surplus and shortage of materials in the process as compared with the new scheme. The model would be a good tool for accurate prediction of quantity of the raw material required in the production process.Nomenclature, the proportion of material used per ton of the processed product, the quantity of material in processed product (ton), the material proportional per ton of the product, andthe total quantity of materials needed per ton of the product,..., the counter for material type,..., the counter for material proportionality variant

A company should maintain an adequate or optimal level of inventory so that production operations can run smoothly and efficiently. What needs to be considered in this case is that the required raw materials are always available, so as to guarantee the smooth production process. However, the amount of inventory should not be too much because this will harm the company. Too much inventory will increase maintenance costs and storage costs in the warehouse. In addition, the amount of inventory that is too much can also increase the likelihood of losses due to damage and loss of quality that can reduce company profits. And vice versa, the amount of inventory that is too small will hamper the production process so that the company will suffer a lot of losses including: the machine does not work as it should, many workers are unemployed, and can even result in the cessation of the production process. This study aims to determine how the calculation of raw materials, what is the total cost of raw material inventory if the company establishes an EOQ (Economic Order Quantity) policy, what is the limit or point of ordering raw materials needed by the company during the grace period at PT.Bentoel International Investama in Malang.The population used is the supply of tobacco raw materials at PT. Bentoel International Investama, where this research was conducted by interview and documentation. The variable in this study is the supply of raw materials. The analysis used is the EOQ (Economic Order Quantity) method.The results of the study, if using the EOQ method in 2017 the cost savings of Rp 40,290,256,931, while in 2018 the cost savings of Rp. 44,388,428,549. Thus there is a difference between inventory policies carried out according to the company with EOQ calculations. It can be concluded that the supply of raw materials every year has increased raw materials, the frequency of purchasing raw materials when using raw materials when using the EOQ method is 2 times in one period, the limit for ordering raw materials needed by companies when using the 2017 EOQ method is 218,176.7 kg, while in 2018 it will be 210,853 kg. The total cost of raw material inventory calculated according to EOQ is less than that spent by the company, so there is a cost savings of raw material inventory

The increase, in quantitative and qualitative terms, of research attending to the geological nature of rocks found in archaeological contexts is changing our perspectives about social and economic territories articulated by Palaeolithic societies in the Cantabrian Region. Practically the only raw material researched in a solid geoarchaeological approach in this area is flint. This paper addresses how the near absence of in-depth geoarchaeological research into raw materials other than flint is modifying our perception of the procurement and management mechanism of raw material in the Cantabrian Region during the Palaeolithic. To consider this matter in depth, we present the bibliographic and quantitative analysis of 30 representative archaeological sites from the Cantabrian Region whose assemblages were described lithologically using basic and primary categories. The state of play depicts a geographic distribution of raw material in the Cantabrian Region where quartzite is associated with the western sector and flint with the east. Interconnected with this axis, there is a chronological tendency that promotes standardisation in the use of flint by Palaeolithic societies following a chronological order, from the older to the more recent periods. This information, and its contextualisation with the new perspectives resulting from the application of the geoarchaeological proposal used to understand flint procurement, allows us to understand the general tendencies of raw material distribution of the region. Especially, we can detect how the absence of geoarchaeological methodologies of other raw materials than flint has modified the perception of the economic and social dynamics articulated around raw material by Palaeolithic people. This bias does not only affect the geographical and chronological axes, emphasising information from the regions and periods where flint is represented, but also promotes the over-interpretation of long-distance procurement, therefore, building up narratives exclusively based on human mobility. This situation has generated an incomplete and unbalanced picture of the procurement and management strategies followed by Palaeolithic societies because quartzite, the second most-often used lithic raw material, and other raw materials have only been studied using geoarchaeological methods within the last few years. This research finally points to the continuation of in-depth research of quartzite and other raw materials as the next steps to re-interpret the current paradigms about procurement and management of raw material by Palaeolithic societies, and, therefore, modify our perspectives of social and economic territories. The research presented here addresses this situation and proposes the in-depth research of quartzite as the next step to re-interpret the current paradigms about procurement and management of raw material by Palaeolithic societies, and, therefore, modify our perspectives of social and economic territories. To do so, we have proposed a general raw material framework in the Cantabrian Region based on the 30 most representative sites whose assemblages were described lithologically using basic and primary categories. The state of the art depicted a geographic distribution of raw material in the Cantabrian Region where quartzite is associated with the western sector and flint with the east. Interconnected with this axis, there is a chronological tendency that promotes standardisation in the use of flint by Palaeolithic societies following a chronological order, from the older to the more recent periods. This information, and its contextualisation with the new perspectives resulting from the application of the geoarchaeological proposal used to understand flint procurement, allows us to understand the bias derived by the absence of geoarchaeological methodologies of other raw materials than flint. These biases are not only related with the geographical and chronological axes, emphasising information from the regions and periods where flint is represented, but also with the overinterpretation of long-distance procurement, therefore, promoting narratives exclusively based on human mobility.

Introduction. Medicinal plant raw materials are one of the most important sources of herbal remedies used both for the prevention and treatment of a number of diseases [1, 2]. Even with the development of modern science and chemistry, medicinal plant raw materials are widely used in both folk and official medicine. The advantage of medicinal plants is their wide range of biological activity, low toxicity and the possibility of long-term use without significant side effects. Human economic activity has a noticeable negative effect on the condition of wild-growing plants: their stocks are decreasing, and some species disappear altogether. Today, given the high level of development of industry and agriculture, the procurement of raw materials for wild medicinal plants is not always possible. Information on the quantitative assessment of the raw material base of wild medicinal plants in the Middle Urals, the content of biologically active substances in medicinal plant raw materials is partially outdated, which determines the need for their systemic resource study and chemical-pharmacognostic study.Aim. Comprehensive assessment of the state of populations of wild medicinal plants in the Middle Urals.Materials and methods. Determination of stocks of raw materials of the studied species of medicinal plants was carried out on specific thickets according to the generally accepted method. The authenticity of the raw materials was established by a macroscopic method when collecting raw material samples. In the course of the study, samples of medicinal plant materials of 5 types were prepared. The determination and assessment of the main indicators of the good quality of medicinal plant raw materials (the content of active and extractive substances, moisture in the mass upon drying, total ash and ash insoluble in a 10% solution of hydrochloric acid) was carried out according to the methods and requirements of the State Pharmacopoeia of the Russian Federation XIV edition. In the raw materials Artemisiae absinthii herba and Leonuri herba, the amount of extractives was determined by the gravimetric method. The quantitative assessment of the content of essential oil in the samples of Origani vulgaris herba and Tanaceti vulgaris flores was carried out by the method of hydrodistillation. To determine the quantitative content of the sum of flavonoids in Hyperici herba, Artemisiae absinthii herba, Leonuri herba and the sum of flavonoids and phenolcarboxylic acids in Tanaceti vulgaris flores, a spectrophotometric method was used.Results and discussion. In the course of resource and phytochemical studies of representatives of the medicinal flora of the Middle Urals, a comprehensive assessment of the state of populations of wild medicinal plants – sources of medicinal plant raw materials (Origani vulgaris herba, Hyperici herba, Tanaceti vulgaris flores, Artemisiae absinthii herba and Leonuri herba) was carried out. The results are included in the electronic inventory of wild medicinal plants of the Middle Urals.Conclusion. The conducted complex of studies will allow updating information about the medicinal flora of the Middle Urals in order to use raw materials for the creation of medicines.
