Abstract

Teknologi internet berkembang dengan pesat khususnya di bidang sistem informasi dan telekomunkasi. Pada dasarnya semua orang yang terhubung ke internet dapat bertukar informasi dan data. Untuk mendukung komunikasi agar berjalan dengan baik, penulis membutuhkan analog terminal adapter yang berfungsi untuk mengubah sinyal analog dari telepon dan mengubahnya kembali menjadi digital sehingga dapat ditransmisikan melalui internet. Dengan melakukan konfigurasi pada server Asterisk, penulis telah menghasilkan komunikasi antara IP-phone dengan IP-phone dan komunikasi antara telepon konvensional dengan IP-phone. Dengan memanfaatkan Private Automatic Branch Exchange (PABX) yang dikonfigurasi pada server Asterisk, maka telepon konvensional dapat terhubung dengan IP-Phone, sehingga sistem PABX secara hybrid dapat diimplementasikan.

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

The dry season in Batam brings the threat of drought. The dry season has an impact in the form of the threat of fires in settlements and protected forests in the Rempang and Galang Islands, Batam. Based on the survey and analysis activities in 2018, it is known that residential areas in Pasir Panjang Village often experience fires, however, residents do not yet have the knowledge and ability to handle early fire disasters. In the 2018 community service activities, socialization was carried out with the Batam City Fire Service, but it had not yet reached the technical realm. Fire handling training is required for residents with fire extinguishers, however, residents' access to this tool is still limited and the price is quite expensive. This activities has produced an application prototype based on augmented reality to simulate the use of a fire extinguisher as a media for educating citizens. The application prototype has been tested and can serve as a training medium for residents. In addition, this community service program also provides training and assistance in handling in a fire disaster.
