Title A name given to the resource TELKOMNIKA Telecommunication, Computing, Electronics and Control Design of UTeM logo-shape wearable antenna for communication application by graphene silver nanocomposites Subject The topic of the resource Graphene, Silver, Textile substrate, Wearable antenna, Wireless communication Description An account of the resource Previously, the antenna conductive patch was made of copper, which was costly, susceptible to multi-fading, bulky, environmentally sensitive, and difficult to produce. Because of their exceptional electrical conductivity and superior strength to metal, while remaining versatile, the miracle nanotechnology of graphene has made them a possible candidate to replace uncompromising copper metallic content. As a result, graphene is incorporated into conductive silver nanocomposites in this work. With the microstrip feeding technology, the suggested antenna design features a logo-shaped made of graphene and silver patch on a textile substrate and radiates at 2.45 GHz frequency. The antenna’s total dimensions are 60×60×1.6 mm. The simulation results were generated using computer simulation technology (CST) studio suite program software, which improved antenna properties including far-fields, return loss, and voltage standing wave ratio (VSWR). Wearable antennas are promising and have a bright future, especially with the advent of wireless communication technologies, so this new design is essential for the materials revolution in advanced communication and IR4.0 applications, as well as wireless sensor applications.

Title A name given to the resource TELKOMNIKA Telecommunication, Computing, Electronics and Control Detection of image manipulation with convolutional neural network and local feature descriptors Subject The topic of the resource Convolutional neural network, Image manipulation chain, Image manipulation detection, Local feature descriptors Description An account of the resource In recent times, numerous digital image manipulation detection approaches have been proposed to detect which processing operations were applied to manipulate digital images. Most of these approaches consider the situation in which an image is manipulated by only one manipulation operation. However, practical image manipulation often involves multiple manipulation operations. It is important to detect multiple image manipulation operations and the order in which they were applied to establish the origin and genuineness of a given image as well as the processing history it has gone through. In this article, we proposed a new method to determine multiple image processing operation and operation chains based on convolutional neural network (CNN) and local optimal oriented pattern (LOOP). The proposed method is based on CNN and LOOP in which CNN extracts and learns image manipulation traces from the LOOP maps of the input images that are classified using softmax, extra-tree, and extreme gradient boosting (XGBOOST) classifiers. Detailed experiments show that the proposed model can attain overall detection accuracies of 99.81% and 99.15% in identifying different image manipulations and manipulation operation chains, respectively.

Title A name given to the resource TELKOMNIKA Telecommunication, Computing, Electronics and Control Energy-efficient speed profile: an optimal approach with fixed running time Subject The topic of the resource Energy-efficient operation methodology, Energy-saving, Metro system, Pontryagin’s maximum principle, Timetable optimization Description An account of the resource Tracking the optimal speed profile in electric train operation has been proposed as an efficient and feasible solution for not only reducing energy consumption, but also no at costs to upgrading the existing railway systems. This paper focuses on finding the optimal speed profile based on Pontryagin’s maximum principle (PMP) while ensuring the fixed running time, and comparing energy saving levels in the cases of applying or not applying PMP. The way to determine the fixed running time also differs from works published is to calculate the total trip time equal to scheduled timetable exactly. Calculating accelerating time ta, coasting time tc, braking time tb via values of maximum speed vh, braking speed vb of optimal speed profile. The other hands, vh and vb are determined by solving nonlinear equations with constraint condition: the running time equal to the demand time. Simulation results with data collected from electrified trains of Cat Linh-Ha Dong metro line, Vietnam show that energy reduction for the entire route when PMP utilization is up to 8.7% and running time complied with scheduled timetables.

Title A name given to the resource TELKOMNIKA Telecommunication, Computing, Electronics and Control Empirical measurement for path loss characteristics at multiple frequency bands from 2.2 to 14.6 GHz in chamber room Subject The topic of the resource EMC chamber, FSPL, Microwave link, Receiver, Transmitter Description An account of the resource Free space path loss (FSPL) is the loss of electromagnetic signal strength. This loss is caused by the line-of-sight path through free space. Even in a line of sight (LoS) indoor single layer, as the distance increases, the path loss in the 1 GHz frequency band also exceeds the free space path loss. This is because the first Fresnel zone is shielded by the floor and ceiling. To improve the measurement results, a fully covered anechoic chamber is used in this empirical measurement. The measurement is based on multiple frequency bands from 2.23201 GHz to 14.685 GHz. This article details how to achieve it. Measurements are made to establish the correlation between the power transmit value and the frequency value. This movement involves the establishment of microwave link transmissions. Use a signal generator to control the transmit power and use a vector network analyzer in the electromagnetic compatibility (EMC) room to measure the received power level. Appropriate analysis that determines the correlation. The logarithm function developed based on the empirical experiment conducted, the result suggested the formulation of LFS = a − b × ln(x + c). These findings enable people to understand the required FSPL value as the power transmission and frequency change during each measurement.

Title A name given to the resource TELKOMNIKA Telecommunication, Computing, Electronics and Control Recent systematic review on student performance prediction using backpropagation algorithms Subject The topic of the resource Data preprocessing, Deep learning, Deep neural network, Students’ performance, Systematic review Description An account of the resource A comprehensive systematic study was carried out in order to identify various deep learning methods developed and used for predicting student academic performance. Predicting academic performance allows for the implementation of various preventive and supportive measures earlier in order to improve academic performance and reduce failure and dropout rates. Although machine learning schemes were once popular, deep learning algorithms are now being investigated to solve difficult predictions of student performance in larger datasets with more data attributes. Deep neural network prediction methods with clear modelling and parameter measurements formulated on publicly available and recognised datasets are the focus of the research. Widely used for academic performance prediction, backpropagation algorithms have been trained and tested with various datasets, especially those related to learning management systems (LMS) and massive open online courses (MOOC). The most widely used prediction method appears to be the standard artificial neural network approach. The long-short-term memory (LSTM) approach has been reported to achieve an accuracy of around 87 percent for temporal student performance data. The number of papers that study and improve this method shows that there is a clear rise in deep learning-based academic performance prediction over the last few years.

Title A name given to the resource TELKOMNIKA Telecommunication, Computing, Electronics and Control Hiding health report in X-ray images to protect people privacy Subject The topic of the resource Steganography, Sudoku method, Turtule shell hiding algorithm, X-ray images Description An account of the resource X-rays images are a popular medical diagnoses method. These images are hard to read and to be understandable outside the medical community. However, the radiologist writes a report of the X-ray. This report can be understandable easily which, can impact the privacy of the patients’ medical records. To tackle this issue, in this work, X-ray image steganography algorithm based on Sudoku mathematical game is proposed. The method converts the image into triangular shaped blocks. Subsequently, the data is encoded and segmented two bits at the time to be embedded in the image. To evaluate the algorithm, eight different X-ray images from all X-ray types have been utilized for data hiding process. The algorithm has been compared to the lest significant bit (LSB) and the turtle shell algorithms using the mean square error (MSE) and peak signal to noise ratio (PSNR) performance metric. The proposed algorithm obtained higher bit per pixel embedding capacity with 2 bpp which is higher than LSB and turtle shell. Moreover, the algorithm has higher PSNR compared to turtle shell algorithm.
