Improving accuracy of derived 12-lead electrocardiography by waveform segmentation Indra Hardian Mulyadi; Nelmiawati Nelmiawati; Eko Supriyanto

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%.

Perkembangan populasi lanjut usia meningkat setiap tahunnya berbanding lurus dengan angka potensi jatuh pada lanjut usia. Jatuh menjadi salah satu kecelakaan yang paling umum terjadi pada lanjut usia. Sekitar 28-35% orang berusia 65 atau lebih di dunia mengalami kejadian jatuh setiap tahunnya. Jatuh dapat berakibat cedera fatal bahkan meningkatkan risiko kematian jika tidak segera ditangani. Untuk meminimalkan dampak yang ditimbulkan jatuh tersebut, telah banyak penelitian yang dilakukan salah satunya dengan metode threshold. Penelitian ini bertujuan membuat suatu sistem pendeteksi jatuh untuk mendapatkan nilai akurasi sistem. Sistem ini memanfaatkan nilai keluaran dari sensor accelerometer dan gyroscope berbasis mikrokontroler dengan metode threshold. Hasil notifikasi jatuh akan dikirimkan dan ditampilkan pada smartphone android. Perangkat ini bersifat wearable digunakan pada bagian pinggang. Penelitian ini menggunakan 6 jenis aktivitas biasa: berdiri, jongkok, berjalan, berlari, naik dan turun tangga, juga menggunakan 4 jenis aktivitas jatuh: jatuh ke kanan, kiri, depan dan belakang. Berdasarkan hasil pengujian yang telah dilakukan, didapatkan bahwa sistem yang dibuat memiliki sensitivitas sebesar 82,50%, spesifisitas sebesar 91,67%, akurasinya sebesar 88% dan tingkat keberhasilan smartphone menampilkan notifikasi jatuh sebesar 96,97%.

Overall Equipment Effectiveness (OEE) adalah metode yang digunakan untuk menghitung nilai efektivitas dari sebuah mesin atau peralatan. Jika nilai OEE ≥ 85%, maka mesin dapat dikatakan efektif. Jika nilai OEE < 85%, maka mesin tidak efektif dan akan dilakukan analisis untuk mencari akar permasalahan, di antaranya menggunakan metode Failure Mode and Effect Analysis (FMEA). Penelitian ini bertujuan membuat sistem penghitung nilai efektivitas mesin forming menggunakan metode OEE. Limit switch dan Arduino UNO digunakan untuk mengambil data output dari mesin, seperti jumlah produksi, total durasi kerja mesin, dan total durasi mesin berhenti. Data diolah menggunakan Microsoft Visual Studio (C#) dan disimpan dalam database sehingga dapat ditampilkan dalam bentuk laporan bulanan menggunakan Crystal Report. Pengujian lapangan sistem ini dilaksanakan untuk menghitung OEE pada mesin die form. Berdasarkan hasil dari pengujian tersebut, sistem penghitung ini berfungsi dengan baik dalam menghitung OEE mesin die form tersebut, yang dalam hal ini berada dalam kisaran 59,05% s.d 97,17% (efektivitas di bawah nilai World class standard).

Modul akuisisi data dengan menggunakan Modbus Remote Terminal Unit (RTU) telah banyak digunakan secara komersial di industri. Namun sayangnya, harga peralatan tersebut tergolong mahal. Protokol komunikasi Modbus RTU ini cukup kompleks untuk dibuat oleh pengguna awam, seperti siswa sekolah menengah vokasi dan mahasiswa. Dengan latar belakang tersebut, penelitian ini bertujuan untuk membuat modul komunikasi Modbus RTU over RS485 yang berbasiskan Arduino sehingga harga pembuatannya menjadi murah dan dapat menjadi sarana pembelajaran di sekolah menengah maupun universitas. Modul yang dibuat ini terdiri atas dua input analog dan dua input/output digital. Sinyal analog yang masuk dikondisikan terlebih dahulu dengan menggunakan signal conditioner sebelum diproses lebih lanjut oleh mikrokontroler. Hasil pengujian menggunakan Modbus Analyzer menunjukkan bahwa komunikasi Modbus RTU over RS485 pada modul yang telah dibuat ini berjalan dengan baik.

Wearable and wireless Electrocardiograph (ECG) enables real-time and long-term monitoring of heart rate (i.e. 24 hours). Several algorithms have been introduced to increase the accuracy of the heart rate calculation for this type of ECG. This study aims to compare the accuracy of two heart rate calculation algorithms: Filter-Based and Peak Threshold. Both algorithms were implemented into a wearable ECG prototype comprising AD8232, 8-bit microcontroller (ATMega328), and Bluetooth. ECG signals and heart rate (in Beat per Minute (BPM)) were sent via Bluetooth and displayed in real-time on a Windows-based application created using Visual C #. Experiments were conducted on 10 healthy subjects aged 20.4 ± 2.0 years and body weight of 60.8 ± 10.2 kg. The measurement results calculated by using Filter-Based and Peak Threshold were compared to a commercial wearable ECG (KineticTM) as a ‘ground truth’. The test results showed that the Filter-Based algorithm resulted in a more accurate calculation with the Root Mean Square Error (RMSE) of 1.53, compared to the Peak Threshold algorithm with RMSE of 2.69.

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.

Washing hands is something that is always urged to be done lately. This pandemic makes washing hands a habit that must be accomplished before and after doing activities. Automatic hand washing is one way to reduce the spread of the virus because it can be used without having to touch the device directly. The development of automatic tools for washing hands is the crucial need for an alternative power source that is fuel-efficient and uncomplicated in terms of maintenance. The eco-friendly electrical source is needed to be implemented to reduce the electricity bills such as using the solar panel as the alternative power source. As an effort to support handwashing activities, the procurement of solar panels as a source of electrical energy is expected to be able to provide simple solutions to prevent the spread of Covid -19 and to make the environment clean and energy-efficient.

The heart is a very important part of the body. The main job of the heart is to pump blood to all parts of the body. The heart has a rhythmic beat when it is pumping blood. This rhythm varies according to the health condition of a person. Therefore, it is necessary to have a system to monitor this rhythm change. The most well-known way to detect the rhythm or speed of the heartbeat is by using sensors. This paper implements a sensing device using a heart rate sensor and an IoT device. The heart rate sensor used is the MAX30100 sensor. As the main processing is an ESP-WROOM-32 which is famous for its WIFI and Bluetooth features. All these devices are combined in a sensor box that is embedded in the faceshield. The result is a faceshield capable of monitoring heart rate and sending the data to various connected devices. The experimental results show the instrument's accuracy value of 9.68% compared to the professional Pulse Oximeter used in hospitals.

The Covid-19 pandemic requires elementary and junior high school students to do online learning activities at home. In practice, children interact more often with their gadget during online school hours and outside these hours. Its a concern for most Graha Nusa Batam community residents because the children there are already starting to have symptoms of gadget addiction. Against this background, Batam State Polytechnic (Polibatam) held a robotics technology workshop program for children aged 8-15 years. This activity aims to increase children's understanding of robotics technology, which includes electronics and mechanics. In addition, this activity provides several benefits, namely: being an attractive alternative for children to reduce playing with their gadgets; provide children's experiences in problem solving, creativity and collaboration; and include field experience for Polibatam students by applying the knowledge gained through Project Based Learning (PBL) for the benefit of the community.This workshop held four meetings (March to April 2021) at the At-Taqwa Al-Qur'an Education Park (TPA) building, Graha Nusa Batam housing. The robot used is an analog line follower. Pre-test and post-test were conducted to measure the increase in participants' understanding of the material. This test shows that participants' knowledge of robotics technology can increase up to 25% for participants aged 8-11 years and 22% for 12-15 years.
