Abstract

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.

Abstract

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.

Abstract

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.
