Improving accuracy of derived 12-lead electrocardiography by waveform segmentation Indra Hardian Mulyadi; Nelmiawati Nelmiawati; Eko Supriyanto
Indonesian Journal of Electrical Engineering and Informatics (IJEEI) Vol 7, No 1: March 2019
Publisher : IAES Indonesian Section

A number of methods have been proposed to reduce number of leads for electrocardiography (ECG) measurement without decreasing the signal quality. Some limited sets of leads that are nearly orthogonal, such as EASI, have been used to reconstruct the standard 12-lead ECG by various transformation techniques including linear, nonlinear, generic, and patient-specific. Those existing techniques, however, employed a full-cycle ECG waveform to calculate the transformation coefficients. Instead of calculating the transformation coefficients using a full-cycle waveform, we propose a new approach that segments the waveform into three segments: PR, QRS complex, and ST, hence the transformation coefficients were segment-specific. For testing, our new segment-specific approach was applied to six existing methods: Dower’s method with generic coefficients, Dower’s method with individual (patient-specific) coefficients, Linear Regression (LR), 2nd degree Polynomial Regression (PR), 3rd degree PR, and Artificial Neural Network (ANN). The results showed that the new approach outperformed the conventional full-cycle approach. It was able to significantly reduce the derivation error up to 74.50% as well as improve the correlation coefficient up to 0.66%.

Wearable-and-wireless Electrocardiograph (ECG) has been widely used for long term monitoring due to practical reasons. Besides its high Signal to Noise Ratio (SNR), one of patch benefits is its flexibility for users to place the electrodes. However, most of existing commercial wireless ECG patches displays Heart Rate Variability (HRV) only, without ability to provide or record the ECG waveform. Some of them employ two electrodes only: Right Arm (RA) and Left Arm (LA), without additional electrode called Right Arm Drive (RLD). In addition, It is beneficial to provide more than one wireless technology option for ECG patch. We propose a low cost wireless ECG patch that has ability to provide ECG waveform (Lead I) and calculate HRV automatically. Besides RA and LA, it utilized RLD electrode to increase Common Mode Rejection Ratio (CMRR). For data processing, we employed ESP32, a low-power 32-bit microcontroller equipped with Bluetooth Classic (BT), Bluetooth Low Energy (BLE), and Wifi in a compact module. The test results showed that the proposed ECG patch resulted in more accurate HRV calculation as well as 2,7 times faster transition time compared to a commercial product.

Project-Based Learning (PBL) is a learning method that is based on Student-Centered Learning activities by conducting active exploration of learning and solving existing problems. The PBL method has been believed in increasing student motivation, competence and soft skills. This is the basis for Cyber Security Engineering Study Program, Informatics Engineering Department, Politeknik Negeri Batam to transform, develop conventional-based learning towards PBL. Existing PBL-based learning implementations also vary depending on the project, problem, or product produced. This study provides an overview of the PBL design by providing examples of projects that can be carried out, as well as the stages of implementing PBL that follow the industry standards (hardware, software, services) through Agile method. This is the first step in realizing the implementation of PBL in the study program so that it can improve student soft skills and hard skills in solving problems especially in Cyber Security field.

BMN has meaning of all assets acquired from APBN expenses or other legal acquisitions. Politeknik Negeri Batam is required to manage, use and maintain in order to get benefit from these assets. Utilization of technology is an absolute solution in this management. The current management system works conventionally whereby an inventory number is printed on a label in each item. A difficulty found when it uses to track and check for inventory during daily usage or maintenance. A BMN QR code-based system is proposed which consists of two applications, namely web and mobile. The application was developed using an iterative prototyping method in order to get speed and accuracy according to user needs. The mobile application uses to quickly access goods data by scanning the item code, while a web application with a QR Code generator used to manage item data and create a QR Code based on the code item. Mobile applications were developed using the Ionic Framework, while web applications were built with AngularJS. The application testing results show that all defined functionalities can function and meet user needs.

CTF (Capture The Flag) competitions have emerged as a pivotal instrument in development of cyber security education over the past six years. It is imperative to ensure that the CTF competitions continue to develop to facilitate growth of cyber security education. To achieve the desired growth, it is necessary to analyze the progress achieved in the last six years the program has been implemented. This research collects and analyzes approximately 500 CTF solutions from the CTFtime platform. From the results of this analysis, we have identified that skills and techniques are needed in each category of CTF questions. We use the results of this analysis as a reference for questions on the CTF Platform that we created during PCT (Polibatam Cyber Team) regeneration. PCT consists of a group of students from the Cyber Security Engineering study program who are prepared to be at the forefront in participating in various activities related to Cyber Security. The method we use is different from other CTFs, in that we use a skill-based and technique-based approach. We found that this approach was able to attract 80% of participants in solving and improving their skills in Cyber Security towards any challenges in a competitive environment.

Politeknik Negeri Batam is one college that gives higher priority to practicum activity. Students are therefore faced with a larger practical task than theory, making it more laboratory than practicum sessions. While access to the lab is quite limited. Virtual computer labs using Cloud Computing technology can be a solution to overcome this limitation. The author has been doing research on the design of Cloud Computing's virtual computer lab using OpenStack on a centralized network and has got some results. Tests are performed with specific server specifications and use the OpenStack platform. And the results of testing of the virtual computer lab with case studies of object-based programming courses show the server used during testing can run virtual computer lab with 9 computers well. While in the case study there are 30 computers per lab. This is due to hardware resources that are not good enough.
