In the Covid-19 condition, students have difficulty in conducting online practicum learning. Various platforms are used to carry out the online learning process so that it needs to be supported by good facilities and the use of information technology. One of the newest innovations to get information today is Virtual Reality. How Virtual Reality works will make it seem as if students are doing a Digital Engineering practicum at the Electrical Engineering Laboratory of the Sriwijaya State Polytechnic. In addition to displaying a visualization of the Digital Engineering practicum, this tool will be equipped with an audio explanation of the practicum. Then after the 3D object has been created, the user will need additional devices, namely VR glasses to help users enter and interact directly in the 3D world.","PeriodicalId":177278,"journal":{"name":"Atlantis Highlights in Engineering","volume":"23 2 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":"121250407","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}

Large reactive power consumption may give problems to electrical power supply and distribution system such as lower power factor, higher power loss for both electrical power distribution system and all electrical power devices connected in it, and higher voltage drop in electrical power distribution system. Therefore, a measure known as reactive power compensation (VAR compensation) by connecting power capacitor as reactive power source need to be taken. However, VAR compensation measure may give other problems to the electrical power supply and distribution system. This paper describes effects of using capacitor for VAR compensation to the quality of electrical power supply and distribution system based on simulation run with Matlab Simulink software. Three different kinds of VAR compensation method are analysed i.e., connecting a small capacitor for each inductive load, connecting a large capacitor at the electrical power supply side in which its reactive power flow is controlled by SVC (static VAR compensator) method and connecting a large capacitor at the electrical power supply side in which its reactive power flow is controlled by TSC (thyristor switched capacitor) method. Analysis results show that all the three VAR compensation methods successfully improve or increase power factor of the electrical power supply and distribution system close to unity. However, both the SVC and TSC VAR compensation methods increase harmonic content of voltage and current of the electrical power supply and distribution system as indicated by its high total harmonic distortion (THD) value. On contrary, the VAR compensation method by connecting a small capacitor for each inductive load brings no effect on increasing of harmonic content of voltage and current of the electrical power supply and distribution system.","PeriodicalId":177278,"journal":{"name":"Atlantis Highlights in Engineering","volume":"130 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":"122435607","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}

This method aims to minimize the weight of the building as the magnitude of the earthquake that hits the building is directly proportional to the building's weight itself. The floor plate of the building is made of reinforced concrete with a weight of 240 kg/m. Therefore, this study used 30x30 mm lightweight steel hollow as a hole-forming and as a substitute for shrinkage and temperature reinforcement. This plate was assembled to flexural reinforcement with a diameter of Ø6 -100, the compressive strength of concrete (fc= 25 MPa), thus forming a one-way slab measuring 880x440x90 mm. After the slab had been cured for 28 days, the flexural strength was tested with an Automatic Tension & Compression Testing Machine having a capacity of 3000 kN. As a comparison, the test items were created of two samples with different hollow placements of 3, 4, 5, 6 hollow and solid plates. The major goal of this study is to determine the modulus of rupture (MOR), modulus of elasticity (MOE), and weight reduction owing to the use of lightweight steel hollows as hole-forming and replacement for shrinkage and temperature reinforcement in hollow concrete slabs. The results showed that using 5 and 6 lightweight steel hollows can reduce concrete weight by 10% to 14% while maintaining the maximum modulus of rupture and modulus of elasticity. However, when compared to solid plates, the modulus of rupture and modulus of elasticity were reduced by 60 to 65 percent.","PeriodicalId":177278,"journal":{"name":"Atlantis Highlights in Engineering","volume":"7 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":"115454920","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}

With an incubation period of 14 days, the Covid 19 virus can mutate so that its spread is still ongoing. The ability of the Covid-19 Virus to mutate resulted in the number of Covid-19 virus sufferers continues to increase. To prevent an increase in the spread of the Covid-19 virus, the Indonesian government has imposed Work From Home (WHF). Pembatasan Sosial Berskala Besar (PSBB) and apply the slogan 3M which is wearing a mask, washing hands and maintaining distance. In fact, on the ground, it still cannot suppress the spread of the Covid19 virus continues to increase. But now the Covid19 vaccine can help the prevention process in breaking the chain of this virus. To do the vaccination not a few people who do not want to be vaccinated because of the lack of knowledge about this vaccination itself and the benefits obtained after the Covid19 vaccination. For this reason, socialization is needed as a medium of information for the public to know the positive impact obtained after this vaccination.

However, the high investment costs associated with large-scale TES is still seen as a major barrier. Among others, challenges are space availability and the presence of groundwater. The complexity of the processes and interactions motivate the application of simulation tools for planning such systems. For TES optimization, flexible and detailed models are required that allow to investigate different geometries, insulation levels and boundary conditions, e.g. presence of groundwater (GW). In contrast, fast and easy-to-use models are required for simulations of a TES integrated in a larger system. In this work, different TES models are compared in various simulation platforms: COMSOL Multiphysics, TRNSYS, Modelica/Dymola and MATLAB/Simulink. The paper summarizes the features of the different TES models, shows the different concepts to reduce the model complexity and compares the results with respect to thermal losses and temperature stratification. TES Types and geometries include buried tanks (cylinder, cuboid), pits (truncated cone, pyramid stump) and hybrids (cylinder with cone stump, cuboid with pyramid stump). TES can be built either completely buried or partially buried building a dam with (part of) the excavated soil. Detailed 2D and 3D FE models developed in COMSOL Multiphysics were validated against measured data from a pit TES and were used as reference for this study. Some of the models take advantage of symmetry and cylindrical coordinates in order to reduce the model to 2D (cylinder, cone). Within this work, deficiencies could be identified, models could be improved and also the influence of the user was seen. Overall, good to acceptable agreement between the tools was achieved after a review phase and after eliminating bugs and user influence.","PeriodicalId":177278,"journal":{"name":"Atlantis Highlights in Engineering","volume":"27 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":"126371838","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}
