In order for the soil to carry the construction load on it, an improvement in the structure and density of the soil itself is needed. This is in accordance with the technical requirement that the soil must be hard. If the soil does not meet the requirements, it is necessary to stabilize it by adding embankment soil as in this study which stabilized clay soil with variations of 50% and 75% addition of selected embankment soil. Clay samples were taken in the Keramasan area. The test was carried out in the laboratory of the Department of Civil Engineering, State Polytechnic of Sriwjaya to determine the Comparison of CBR (California Bearing Ratio). The results showed that the original soil sample had a moisture content of 36.15%, a specific gravity of 2.55, a liquid limit of 65, 65%, plasticity index 31.36% and CBR 9.00%. Based on the USCS Classification, the soil sample belongs to the CH type, which is clay with a moderate to poor rating. From the results of soil testing that has been stabilized, the optimal water content is 31%, specific gravity is 2.60, liquid limit is 54.04%, plasticity index (IP) is 24.70% and CBR 11.85 (addition of 50% of selected embankment soil). ). While the addition of 75% of the selected embankment soil, obtained the optimum moisture content of 25.1%, specific gravity 2.60, liquid limit 36.61%, IP 13.19% and CBR 12.02%. It can be concluded that the addition of 75% embankment soil gets a higher CBR value than the addition of 50% of embankment soil and original soil (without addition).","PeriodicalId":177278,"journal":{"name":"Atlantis Highlights in Engineering","volume":" 23","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132095880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The electrical energy produced is still dominated by power plants by conventional energy sources so that the use of alternative energy is needed to prevent the limitation of energy sources. Alternative energy that is often used is a source of solar electricity that produces electricity by utilizing sunlight. In an effort to increase and utilize renewable energy sources, researchers seek to design and implement a smart grid system on alternative energy sources. The smart grid system allows users to monitor and control the energy used by analyzing the direct parameters to be assessed. Using this smart grid system can help overcome limitations in monitoring because it can be done remotely. This system uses the ACS712 sensor to detect the current at the DC load, and the PZEM004T sensor for the AC load. It communicates via an IoT-based internet network using ESP 32 with the percentage of errors obtained in the power dc load test resulting in an error rate of 0.012% and in the power AC load testing of 0.064%.","PeriodicalId":177278,"journal":{"name":"Atlantis Highlights in Engineering","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115953135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Steel can be modified its strength by adjusting the percentage of the amount of its constituent substance composition. Some substances that can be used as a composition in steel include: Iron (Fe), Carbon (C), Phosphorus (P), Manganese (Mn), Sulfur (S), Chrome (Cr), and so on. In addition, according to its use, steel can also be mixed with other substances to form alloy steel. However, most steels are only dominated by a mixture of iron (Fe) and carbon (C) called carbon steel. In its initial condition, in carbon steel, a mixture of Fe and C will form ferrite as the main component of steel. The ferrite contained in the steel will make the steel more ductile, but its hardness value is minimal. In some cases, sometimes steel with a higher hardness value will be needed, with the same percentage of content. For this reason, an effort is needed to increase the hardness value of steel. Efforts to increase the value of this steel hardness can be done by treating the steel with heat treatment. One method of this heat treatment is by quenching. This is done by heating the steel to a temperature of 850C, and then rapidly reducing the temperature. With an increase in temperature, the crystal structure of the steel will deform to a ferlite structure. The ferlite structure will deform again slowly into ferrite as the temperature decreases. However, if the temperature is lowered rapidly, the steel structure will deform to martensite instead of unformed ferrite. The martensite phase is harder than ferrite. This research examines the quenching process using several cooling media on AISI 1045 steel. The cooling media used are: Circulated air, water, lubricating oil, and liquid smoke.","PeriodicalId":177278,"journal":{"name":"Atlantis Highlights in Engineering","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126312177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The energy is therefore also not provided corresponding to the actual need, but according to the availability. Hence, the demand for energy storage is rising with the increasing utilization of renewable energy sources, tackling the difficulties coming along with it. Carnot-Batteries are one out of a few geographically independent storage possibilities for longer durations. The thermal energy storages employed in Carnot-Batteries vary from liquid molten salt storage with two-tanks or single-tank thermocline storage to packed bed configurations with encapsulated PCM or natural solid materials, like rocks. Storage materials, which are found plenty in nature, having nearly no direct impact on the environment, are water and rocks. Natural Rocks offer a greater temperature span for operation than water and are therefore suitable for a wider range of applications. A possible natural rock for use in thermal energy storage is volcanic material basalt. In this experimental work, basalt, after its usage in cast form as flue pipes in a power plant, is analyzed, focusing on its properties for energy storage applications. Using this product would offer the reuse of an otherwise not anymore useful, leftover product and provide a storage material without the need of taking it from nature. The experimental research to retrieve the speed of reaching the full potential heat capacity of this product is described. The samples of basalt and the basalt product are analyzed at different temperatures from 300°C to 750°C. Additionally, air cooling, from these temperatures down to 100°C, and surface structure changes are evaluated. Insights into important boundary conditions for employment as storage material are given. In future work, it is anticipated to use these results as the base for a charging model of the basalt product and its validation.","PeriodicalId":177278,"journal":{"name":"Atlantis Highlights in Engineering","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116879355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
