Authors: Ali Muhamad , Arifin Zaenal 
Published: December 2021

Abstract
PT Barata is one of Indonesia’s leading turbine component manufacturers, requiring a large amount of electricity for production. Along with the increase in production and factory expansion, the need for electricity continues to increase so that it continues to add power to reach 3780 KVA. One of the weaknesses of the electric power system at PT Barata is using six (6) 20kV/400 V, 630 kVA transformer units. This system produces a no-load or core loss of 8150 Watts. In one year, the power loss reached 71.394 kWh at the cost of IDR 118,514,040.00. Power loss is permanent and lasts all the time during the use of the Transformer. This article aims to redesign the electrical system at PT Barata using a single 4000 kVA transformer. The redesign of the electric power system at PT Barata was carried out by 1. Observing and measuring the electric power system at PT Barata, 2. calculating the resulting losses, 3. conducting studies and designs, 4 comparing the ratio of the total power loss of the electric power system currently with a new design, 5. Propose a redesign to management for implementation. Calculation and analysis of the new design with a 4000 kVA transformer obtained a core loss of 4450 Watt at the cost of Rp. 64,905.030.00, resulting in a savings of IDR. 53,965,980.00 per year. The new design will save 45% in operating costs compared to the previous six transformer units.

Abstract
In the previous article about detecting train arrivals [4], we discussed the data transmission process which is the weakness of the system. This article discusses how to overcome these shortcomings. Distance detection systems need to be added to devices that are more powerful and faster in transmitting data. The prototype is built based on the development of the previous prototype. The initial product is a distance detector that has a motion sensor and a data transmission module in the form of Lora 400 MHz and a GSM module. Product development includes the addition of the NodeMCU WIFI module to existing devices. System development aims to: (1) Develop a distance detection system equipped with a WIFI module; and (2) Increase the data transmission speed of the distance detection system equipped with the WIFI NodeMCU module. The implementation method uses research and development techniques [3]. System development takes 6 months, with the stages of completion being system requirements analysis, hardware, and software design, system prototyping, and tool testing. Checklist data and delivery time are used as test data. Furthermore, the data is analyzed quantitatively to determine the achievement of results according to predetermined indicators. The device is equipped with a GPS module, a Lora-R02 receiver and transmitter module, and a Nodemcu ESP8266 module as a replacement for the 900A SIM module which transmits data faster. When the device is being tested, all the sensors of the tool work well at range of 125 meters (previously less than 100 meters). While the Lora module can react when the object has reached a distance of 300 meters. Data transmission previously using GSM modules took 10-13 seconds. After using the WIFI module, data transmission only takes 1-3 seconds.

Abstract
Testing the performance efficiency aspect was carried out to test the performance efficiency of the Unity 3D and Blender-based virtual laboratory media during the COVID-19 pandemic at the Electrical Engineering Vocational Laboratory. This test is carried out to test the performance of the media that has been created. The aspects tested are access speed, process speed, and simulation speed when run. Tests were conducted to measure processor and memory consumption through real time monitoring using MSI Afterburner. Divided into 2 stages of testing, namely time behavior and resource utilization. Time-behavior is focused on how long it takes the media or software to provide a response time to perform an action from a certain function. Resource-utilization is the degree to which software uses some resources when doing something under certain conditions.

Authors: Quan Zhaolong , Xing Jie , Cao Ruilin 
Published: December 2021

Abstract
With the development of the city, a huge number of distribution networks are waiting for planning. A reasonable planning scheme can meet the power demand and reduce the investment cost. In this paper, a life cycle cost model including the investments of substation and wiring is established with the constraints about load flow calculation and maxi-mum load of wiring. Additionally, a multilayer planning method based on the Floyd-Warshall algorithm has been proposed to solve the model. The area of the city containing substations is divided based on the position of load through the hybrid clusters algorithm in the method. Then, using the divided result of power supply area, the cost matrix for the multilayer path planning method can be constructed through the principle of the method. Lastly, with the cost matrix, the planning scheme in each area will be provided by the Floyd-Warshall algorithm. The result on the actual planning area between the two algorithms shows the total cost of the investment is decreased through using the planning method in this paper.

Published: December 2021

Abstract
In order to fully mine the relationship between temporal characteristics in load data and improve the accuracy of load forecasting, a load forecasting method based on convolutional neural networks (CNN) and gated recurrent unit (Gru) hybrid neural network is proposed. Taking date factors, climate factors and similar daily load factors as input, the sample data sets in the region are grouped by K-means clustering method; Then cnn network is used to extract the relationship between features and load in high-dimensional space, construct the high-dimensional feature vector of time series, and input the results into Gru network; Finally, the parameters of Gru network model in each group are trained and the load forecasting value is output. The results show that the proposed load forecasting method has significant advantages in forecasting accuracy and efficiency compared with long short term memory (LSTM) network model, Gru network model, cnn-lstm network model, support vector machine regression model and decision tree model.

Published: December 2021

Abstract
The working process of cutter suction dredger is complex, so it is difficult to establish accurate model by traditional physical modeling method. The final yield of cutter suction dredger is directly related to the density of the slurry in the pipeline, while the density is controlled by the swing process. Therefore, by analyzing the measured data of the dredger, it establishes the swing process mathematical model based on subspace theory. The algorithm is based on input–output data, simulation results show the algorithm is effective for the control application.

Abstract
Unfolding techniques are employed to reconstruct the 1D energy distribution of runaway electrons from Bremsstrahlung hard X-ray spectrum emitted during plasma disruptions in tokamaks. Here we compare four inversion methods: truncated singular value decomposition, which is a linear algebra technique, maximum likelihood expectation maximization, which is an iterative method, and Tikhonov regularization applied to χ
2 and Poisson statistics, which are two minimization approaches. The reconstruction fidelity and the capability of estimating cumulative statistics, such as the mean and maximum energy, have been assessed on both synthetic and experimental spectra. The effect of measurements limitations, such as the low energy cut and few number of counts, on the final reconstruction has also been studied. We find that the iterative method performs best as it better describes the statistics of the experimental data and is more robust to noise in the recorded spectrum.

Abstract
The new facility, Extreme Light Infrastructure – Nuclear
Physics (ELI-NP), is a combined laser-gamma nuclear physics research
facility currently undergoing its final implementation stages in
Măgurele near Bucharest, Romania. It already hosts two
fully-operational 10 PW laser arms and, by 2023, it will also house
a γ-beam system based on laser Compton backscattering,
capable of delivering a high-brilliance, low-energy beam at
E
γ ≲ 19.5 MeV. Owing to this unique laser-gamma
instrumentation combination, several types of experiments will be
possible at ELI-NP, including high precision nuclear resonance
fluorescence (NRF) experiments. In this case, the main γ-beam
detection system for performing NRF studies at ELI-NP is represented
by the ELI Array of DEtectors (ELIADE), featuring eight high-purity
germanium (HPGe) segmented clover detectors. The current work
presents the characteristics of two of the ELIADE detectors,
including their photopeak detection efficiency, energy resolution,
and peak-to-total ratio measured using γ-ray sources, as well
as the timing performance obtained via in-beam measurements. For
these latter detector tests, 130La was populated via the fusion
evaporation reaction 121Sb(12C,3n)130La using a beam
energy of 53 MeV at the Horia Hulubei National Institute of Physics
and Nuclear Engineering (IFIN-HH), also located in
Măgurele. Herein, we report on the results of the ^130La
linear polarization measurements taken using the ELIADE detectors as
Compton polarimeters. The results obtained from the in-beam
experiment were compared to several already published works and we
present new information on the transition multipolarity in
130La.

Authors: Singh S K , Priya Sarv , Nadeem Mohd , Alam Md Badar 
Published: December 2021

Abstract
In current period, several structures are being planned and built with structural complicatedness like building with floating columns on different floors and spaces. The buildings accompanying floating columns are extremely detrimental that is constructed in earthquake-prone regions. The current study analyses and compare the buildings with and without of floating column. The columns which are directly supported by a beam without any rigid base are known as floating columns. Various buildings have been constructed with floating columns in India. Typically, it is required to provide larger spacing between the columns to entertain the requirements of parking or reception lobbies. Some of the functional requirements of a building might be satisfied by providing the floating columns but the structural behaviour of the building changes abruptly. The beams that supported the floating columns require more flexure and shear demand than the surrounding beams. In addition, it leads to stiffness unevenness at a specific joint. Columns are the main structural elements that resist the lateral load in a rigid frame and have the importance in the performance of the building under earthquake load The storey’s stuffiness below the floating column is normally reduced. Therefore, an attempt has been made to analyse the performance of a G+5 storey building with and without floating columns and compare structural parameters such as horizontal displacement, storey drift and storey shear under seismic excitation using (ETABS) Software.
Experimental Study on Stabilisation of Clayey Soil Using Cement and Bagasse Ash
Authors: Sharma Tarun , Singh Sandeep 
Published: December 2021

Abstract
In order for the foundation of building to be strong, the soil around it plays a critical role. So, researcher or engineer should have thorough knowledge about the factors affecting behaviour of soil which can be altered by the process of soil stabilisation. This study aims to investigate the applicability of SCBA (Sugarcane Bagasse Ash) to stabilize the clayey soil. Sugar factories produce waste after extraction of sugarcane gets brunt and the ash, hence produced is known as bagasse ash. Soil is treated with partial replacement of cement (3%, 6%, 9% and 12%) and with bagasse ash (2%, 4%, 6%and 8%). A total of 45 specimens were prepared in this study. Later those test specimens were evaluated for compaction properties. The results found after thorough study was that there was increase in the compaction properties with percentage increase in Sugarcane Bagasse Ash up to certain limit.
Experimental Investigation on Mechanical Properties of Compressed Soil Blocks Manufactured Using Waste Materials
Authors: Wani Absar Yousuf , Bhandari Mohit 
Published: December 2021

Abstract
This experimental investigation is done on the earth compressed block prepared by the Waste material. These waste materials are Rice Straw Fiber, marble powder, and Sugarcane Bagasse ash. This waste pollutesthe environment and creates the problem of disposal. Redbrick needs heat treatment which results in air pollution, cement bricks need water for curing which needs waterusage in huge quantity. Marble powder stabilized bricks need sun drying. An increase in marble content in the bricks results in the increment of compressive strength due to the presence of calcium content in the marble powder.it also increases the dry density of the brick because marble powder doesnot absorbs water and can easily fill the voids created by the soil,Sugarcene Bagasse ash andRice Straw fiber. Rice Straw Fiber reduces the compression of bricks reason is fiber cuts off on the pressure and it also creates voids when blended with the soil mix making usage of bagasse in the brick can help in increasing the strength of the concrete due to its pozzalonic action with cement but bagasse ash reduces the dry density of bricks and doesnot affect the strength of bricks because its creates voids and it is chemically neutral in bricks.
A Comparative Study between the Usages of Differently Sized Waste Rubber Obtained From Tires over the Strength Performance of Rigid Road Pavements
Authors: Bhardwaj Manish Kumar , Gupta Sanjeev 
Published: December 2021

Abstract
In this research work, waste rubber obtained from tires is mainly used as a fractional substitution of natural coarse aggregate to improve the strength aspects of the concrete. 3 dissimilar sizes of waste rubber obtained from tires aggregates were used that is of 4mm, 10 mm and 16 mm. Depending upon all three sizes all the waste rubber obtained from tires aggregate were used at 3 different percentages that are at 10 percent, 20 percent and 30 percent. Then several concrete samples were prepared depending upon the shape and percentage of the waste rubber obtained from tires aggregate. Then all these samples were cured and tested after 7 days and 28 days. Depending upon the results obtained after these above-discussed test various conclusions has been drawn which are as follows. It was found that the maximum strength was obtained at 20 percent usage of 4mm sized waste rubber obtained from tires aggregate, the strength obtained at 20 percentage with 4mm size was maximum as compared to all other concrete samples, so it can be concluded that the compressive strength depends upon both the size as well as on the percentage of waste rubber obtained from tires aggregate and with the decrease in size of the waste rubber obtained from tires aggregate the strength was increasing. From the test results of the split tensile strength test and flexural strength test, it was found that the maximum strength was obtained at 20 percent usage of 4mm sized waste rubber obtained from tires aggregate and with the increase in size and percentage the strength was declining. So therefore it can be concluded that both split tensile strength and flexural strength depends upon the size of waste rubber obtained from tires aggregate and the percentage of waste rubber obtained from tires aggregate. From the obtained test results it can be concluded that with the addition of the waste tire rubber the overall internal micro-structure of the concrete improves which further leads to enhanced mechanical strength of the concrete. This was due to the physical properties and the chemical composition of the waste tire rubber particles which fills the internal pores in a broader way and lead to improved mechanical strength.
