Raw materials inventory system at PT.Comfort Aire Aneka Technic stillmenggunakansistem manually, which causes the system procedures haveshortcomings and weaknesses that have not been able to optimize vehicle is inproviding information quickly and accurately.The purpose of this paper is to design a computer-based information system thatfocuses on raw materials inventory information system located on the logistics of PT.Comfort Aire Aneka Technic . So that can be developed a system that could expeditethe process of service and information needs for management and stakeholders. Thissystem can also produce fast and accurate information in the form of reports and dat

Straw biomass - potential raw material for ethanol production

Barley straw was found to be suitable raw material for ethanol production. Straw could be easily pre-treated with steam explosion, hydrolysed to monosaccharides and fermented to ethanol. The optimum harvesting times for bio-ethanol raw material are at grain maturity for barley straw. Potential raw material, barley harvested at full ear emergence, when straw is rich in soluble sugars, need further research

Principles of computer simulation design for the needs of improvement of the raw materials combined transport system

This article is focused on computer simulation design for raw materials transportation. The creation of a simulation model of the combined transport system for the raw materials transportation has its own problematic parts. In general, these are parts, which represent transport nodes, i.e. parts of the system in which raw materials are reloaded from one vehicle to another. The given operations are in practice dependent on the preparedness of all transportation means, which participate in it. To locate operations of reloading of the raw materials from one vehicle to another and the check of the preparedness of the vehicles of the reloading in the simulation system is more demanding because it is necessary to take into consideration several aspects, such as an existence of a vehicle with raw materials, an existence of a vehicle to which it is to be reloaded a suitable freeloader, and so on. The article focuses on defining a procedure and correct steps at the creation of the simulation computer model of the combined raw materials transport system in the EXTENDSIM simulation system based on specific data from a real transport system. As is clear from the proposed procedure of the creation of the combined raw material transport system, as a check element of the transport system preparedness, it is suitable to use the "Gate" block and its features in the EXTENDSIM simulation system. As transpires from the results of simulation of the combined raw material transport system, about 322,000 tons of raw materials at 90-96% with the use of all vehicles is transported during the year.Web of Science23217416

Sluggish raw material markets

During the course of 1986 the prices of most raw materials were under considerable pressure. For 1987 there are no indications of a fundamental change in price trends on world markets

Bioalcohol As Green Energy -A review

Bioethanol has now become a big industry and this industry seems to become much bigger in the near future. People regard bioethanol as renewable and sustainable new energy source, although some contraversies such as the rivalry of bioethanol for human food widely exist. Actually, bioethanol can also be a good source of basic raw materials. In early days, ethylene, the most important organic chemical raw material, was produced from dehydration of ethanol. Later, things reversed as petrochemical industry well developed after World War II, when industrial ethanol was mostly produced mainly via hydration of ethylene. Now that bioethanol has already become an important fuel blender, we should well expect that bioethanol should also be new resources for basic organic raw materials, as well as other more valuable fine and specialty chemicals, instead of merely a fuel blender. Nowadays, countless new bioethanol companies are setting up every day. It should lead to more research on bioethanol also as a starting raw chemical material
