Abstract

Humans have been surrounded by various forms of radiation since creation. The first type of radiation is electromagnetic in nature. Radioactive radiation partly emanates from the earth surface. Nowadays, each of us uses a mobile phone daily. Computers, monitors, and televisions have added seriousness to this issue, as they generate both electrostatic and electromagnetic fields. Electromagnetic radiation can cause everything from insomnia to serious health problems that threaten people lives. It is this study that is intended to bring the issue of the occurrence and localization of such zones into focus. Such electromagnetic radiation, invisible to humans, is faced by a large part of the population. It is dangerous to stay in these locations for a long time. People who sleep in this zone for long periods of time are the most vulnerable. In our study, we also looked at the impact of the use of mobile phones and other devices that generate electromagnetic fields. In this study, our aim was to provide a theoretical overview of this issue, which has not received much attention, and which can be a trigger for many health diseases, especially in combination with geopathogenic zones.

Abstract

The development of EBT in Indonesia is still far from the target of the National Energy Policy (KEN), the EBT mix of 23% in 2025 and 31% in 2050. One form of EBT development is utilizing solar energy in building technology that has high energy efficiency so that the number of electrical energy consumption is close to zero or called nearly Zero Energy Building (nZEB). Therefore, it is necessary to design the most optimal rooftop solar power plant (PLTS) so that it has good energy production and economic feasibility. To get a good energy production, simulation is carried out using HelioScope software by inputting data on the mechanical and electrical segments so that the amount of energy that can be produced by the rooftop solar power plant is obtained in detail. The results of the simulation of the rooftop solar power plant system that is installed on-grid in HelioScope are composed of 96 monocrystalline solar panels of Trina Solar TSM-DE20-605W (605W) and 3 3-phase inverters of Growatt MID 17KTL-X. The rooftop solar power plant produces an annual production of 84,08 MWh with a performance ratio of 82,1%. Thus, the average percentage of energy supply from rooftop solar power plants is 39,82% or can be said to be good in supplying the electrical energy needs of buildings so that the nZEB can be developed. From the simulation results, the economic feasibility is known, with the Break Even Point (BEP) reached in 12,4 years of the 25 years project period, and the Net Present Value (NPV) and Return on Investment (RoI) are positive, indicating that the rooftop solar power plant is profitable and feasible to develop.

Abstract

The integration of Renewable Energy Plants, especially Hydrogen, is one of the considerations in supporting net zero emissions in 2025 by 23% following the renewable energy mix plan at RUPTL. To determine the network impact due to the integration of the Green Hydrogen Plant (GHP) with transient study scenarios, system reliability, and reserve margin. The method for determining the capacity of the Green Hydrogen Plant (GHP) is by looking at the Renewable energy quota allocated in the isolated grid area. From the results of the study obtained in this transient simulation, the system frequency value is still within safe limits in the grid code, where the results of the swing frequency value are at least 98.5%. For Power Angle stability, the lowest swing result of -700degree is obtained within 5 seconds. So the reactive power requirement is 0.75 MVar of the system in the swing requirement of the trip condition. The reliability index obtained by the system, when interconnecting with the Green Hydrogen Plant (GHP) has a better reliability level value. This can be seen from the index of disturbances saifi, saidi, caidi is getting lower. The system reliability index is still within safe limits following SPLN 68-2: 1986. In addition, the interconnection system with the Green Hydrogen Plant (GHP) has the highest reserve margin of 3.25 kW at 09:00, when the Green Hydrogen Plant starts production capacity of 5 MW.

Abstract

Marble is a material that is commonly used for building components such as furniture, flooring, countertops, bathrooms, windows in homes etc. Due to the many uses of marble in various aspects, marble surface detection is important for this industry to improve quality and avoid financial problems that may occur. In previous research, many methods such as wavelet transform, Gabor transform, co-occurrence matrix and artificial neural network were implemented in defect detection (fabric or other tasks). In this study we built a platform that aims to detect anomalies on marble surfaces using Autoencoders architecture, Keras library and Python programming language. To test the model that has been created, a marble surface dataset obtained from kaggle.com, one of the largest dataset provider sites, was used and an accuracy of 89% was obtained. The conclusions of this study include the effectiveness of this method in detecting anomalies, the advantages of the autoencoder architecture compared to other methods, and the potential practical applications of these findings in various fields. By utilizing the autoencoder's ability to reconstruct data, anomaly detection can be performed by comparing the reconstructed results with the original data. The main advantage of this approach lies in its ability to tackle the problem of anomaly detection without the need for class labels

Abstract

Nowadays, electric trains are experiencing a transition from diesel fuel to renewable energy. Hybrid electric trains can prove progress from renewable energy, even though they require more than one energy source such as fuel cells and batteries, because renewable energy cannot stand alone. This results in an increase in voltage on the Fuel Cell (FC) which can have an impact on current density and a decrease in voltage, thus requiring a protected DC-DC Converter type circuit to obtain ideal and dynamic condition characteristics. To overcome this problem, the IFBC (Interleaved Full Bridge Circuit) DC-DC Converter is highly recommended as a voltage regulator. There are several methods used to regulate MOSFET’s which in this case affect the IFBC DC DC Converter settings, one of which is the SMC (Sliding Mode Control) method. SMC is a type of non-linear control that functions functionally to control variable structures. However, the application of SMC requires a considerable switching frequency, which has the potential to cause component loss, therefore the switching frequency needs to be limited to that range. To overcome this problem, a method is needed to identify the IFBC output voltage control process using the SMC method in Fuel Cell applications and the software which is considered the most efficient in carrying out this, namely SIMULINK MATLAB software.
