A study of the utilization of hydrogen cogeneration with nuclear energy as a technology for the conversion of CO2 into synthetic liquid hydrocarbon fuels has been carried out. The aim of the study is to understand the conversion of CO2 and H2 into synthetic fuels, as well as the role of nuclear hydrogen cogeneration for the production of hydrogen and as a source of process heat energy. The method used is literature study based on the results of existing research. Conventionally, synthetic fuel production from coal is produced through coal gasification process, followed by reacting synthesis gas (mixture of CO and H2) in FT reactor to synthesis fuel. In this study, we studied the production of synthetic fuels with CO2 and H2 raw materials. CO2 comes from emissions of coal-fired plants, whereas H2 is produced by nuclear hydrogen cogeneration systems. The results show that compared to conventional processes, CO2 and H2-based processes supported by coal cogeneration systems provide significant advantages in terms of CO2 emissions. The process based on coal gasification and nuclear cogeneration, capable of reducing emissions by up to 75% and saving up to 40% of coal consumption. While the process based only on CO2 and nuclear hydrogen cogeneration (without coal gasification), teoretically can operate witout any CO2 emission at all. Even this process can captured and utilize CO2 emissions from coal fired plant, and use it as a raw material for the process.

In 2016, the development of Gempar Tunggal Micro Small and Medium Enterprises (MSMEs) that involved in the processing of black onions began. The raw materials are obtained from the Medan City market center, but sometimes it also come from Brebes and Semarang. The goods manufacture that resulted are sold to Aceh, Kalimantan and Sulawesi. However, because it was a home industry, the manufacturing system that was developed still very simple. Therefore, some weakness were identified, in particular the percentage of damaged or defective finished goods reaching 25 percent before its sold, various levels of maturity and work processes and supervision that drained attention and energy. In addition, the cost of using electricity is also high. It was found from the literature study by the Abdimas team of USU that there are 3 parameters that affect the processing of onions, namely garlic which is sensitive to temperature, humidity and exposure period of temperature and humidity. Often, due to the unequal size of the raw onion amount, the maturity of the onions is not homogenous distributed made the bigger the raw material of the onion impacted the faster it will ripen. Another problem that found during manufacturing process is the water vapor was not completely evaporated from the furnace. Basic technology that was developed by Abdimas USU team, namely the manual gravity onion sorting and drying unit was already used by Partners in the production process. As the result, it was successfully reducing broken onions. Lastly, homogenous maturity due to dividing process the onions by scale obtained.

Introduction. The objective of the research is to study the effect of the complex activation of the alumina raw material on the rheological properties of the ceramic mass. In addition, the authors investigate solutions for the application of optimal coagulation structures based on loams and ash together with plastic certificates.Materials and methods. The authors used the local forest like reserves of clay loams at the BashKarasu, ash fields of the Bishkek Central Heating Centre (BTEC) and plasticizer (sodium naphthenate obtained from alkaline chemical production wastes) as fibrous materials. Moreover, the authors defined technological properties of raw materials within standard laboratory methodology in accordance with current GOSTs.Results. The researchers tested plastic durability on variously prepared masses for the choice of optimal structures. The paper demonstrated the plastic durability of complexly activated compounds comparing with non-activated and mechanically activated compounds. The sensitivity coefficient increased the amount of clay loams by mechanically and complexly activated, which predetermined the possibility of intensifying the process of drying samples based on complexly activated masses.Discussion and conclusions. However, mechanical activation of clay material reduces the period of relaxation and increases the elasticity coefficient of ceramic masses by 1.8–3.4 times, meanwhile decreases elasticity, viscosity and the conventional power during molding, which generally worsens the molding properties of the masses. Сomplex activation of ash-clay material decreases the period of relaxation and provides an increase in elasticity, plasticity of ceramic masses by 46–47%, reduction in viscosity by 1.5–2 times, conventional power on molding by 37–122% in comparison with MA clay loams. Ceramic masses based on spacecraft alumina raw materials belong to the SMT with improved rheological properties; products based on them pass through the mouthpiece for 5–7 seconds.

Organic materials that are generally used as raw material for organic fertilizer granules (POG) is a natural organic material that has been degrade, smooth and dry. One of the main raw materials are always used with a very high percentage of usage, is manure. Manure potential in Indonesia is very high, amounting to 113.6 million tons per year, or 64.7 million tons per year to the island of Java. From this amount, it will be generated numbers POG production potential of 17.5 million tons per year (total Indonesia) or 9.9 million tons per year for the island of Java. While the realistic POG production predictions figures made from raw manure is 2.5 million tons annually, a figure that has been unable to meet the number requirement of POG greater than 4 million tons per year. Therefore, in producing POG, it should be to maximize the using of the potential of other organic materials so that the use of manure can be saved. With the use of a small amount of manure (maximum 30% for cow manure), it would be useful also to avoid the production of POG with high Fe content.keywods: organic material, manure, granule organic fertilizer
