Abstract

ABSTRAKData World Health Organization (WHO) pada tahun 2014 menunjukkan bahwa di Indonesia sebanyak 37% dari seluruh penyebab kematian adalah penyakit yang berhubungan dengan jantung. Kehadiran teknologi dan pemanfaatan Internet of Things (IoT) diharapkan dapat membantu mengurangi resiko kematian akibat penyakit jantung tersebut. Pada penelitian ini, pengukuran dan pengamatan sinyal jantung melalui tele-auskultasi sinyal elektrokardiogram (EKG) dilakukan. Untuk mengamankan sinyal EKG dalam proses transmisi melalui jaringan Internet digunakan metode anonimasi sinyal berbasis algoritma Jusak-Seedahmed. Hasil pengujian menunjukkkan bahwa algoritma Jusak-Seedahmed dapat melakukan proses anonimasi dan proses rekonstruksi sinyal dengan baik. Pengujian korelasi silang antara sinyal hasil rekonstruksi dan sinyal EKG asli sebelum anonimasi menghasilkan korelasi sebesar 1 pada lag=0. Sinyal EKG hasil rekonstruksi ditampilkan dalam aplikasi mobile untuk memudahkan analisis oleh dokter.Kata kunci: elektrokardiogram, keamanan, anonimasi, IoT, FFT ABSTRACTBased on the latest data released by the World Health Organization in 2014, deaths caused by cardiovascular disease in 2012 have reached 37% of the total number of non-communicable diseases deaths in Indonesia. Therefore, it is expected that the applications of the Internet of Things (IoT) might be used to reduce the risk of death due to the heart related problems. In this research, a tele-auscultation technique for measuring and monitoring electrocardiogram (ECG) signal was built. To secure transmission of the ECG signal over the Internet, we implemented a recently proposed Jusak-Seedahmed algorithm. Our examinations showed that the algorithm performed the anonymization and reconstruction processes well. Crosscorrelation analysis showed that correlation between the reconstructed and the original ECG signal at lag=0 was 1. Furthermore, a mobile-based application had been built to display the reconstructed ECG signal for further analysis.Keywords: electrocardiogram, security, anonimization, IoT, FFT

Abstract

The development of artificial intelligence (AI) and robotics has revolutionized various aspects of modern healthcare, including diagnosis, surgery, and rehabilitation. The webinar, titled "Developments in AI and Robotics in the Health Industry," was organized by the Dinamika University Computer Engineering Undergraduate Study Program as a form of community service to increase technological literacy in the health sector. This activity aimed to introduce AI technology and medical robotics and explain the application and ethical, technical, and policy challenges in its implementation. The webinar, which was held online via Zoom, was attended by 160 participants from various backgrounds, such as students, lecturers, health practitioners, and technology developers. The material covered the evolution of robotic systems, the level of autonomy of medical robots, and the potential integration of AI for clinical decision-making. Survey results showed that participants were very enthusiastic and highly rated the relevance of the theme, the competence of the speakers, and the usefulness of the material. This positive feedback from the participants reassures the audience about the quality and relevance of the webinar's content, instilling confidence in the potential of AI and robotics in healthcare. The webinar also had a significant impact on interdisciplinary research, inspiring new collaborations and open discourse on academic cooperation. The webinar also encouraged the utilization of AI and robotics technology in the Indonesian health system, contributing to the digital transformation of the health sector and expanding public understanding of the latest medical technology innovations.

Abstract

Program Pengabdian Kepada Masyarakat (PKM) ini bertujuan untuk meningkatkan pengetahuan dan keterampilan siswa-siswi di SMAN 1 Taman Sidoarjo mengenai Teknologi Informasi dan Komunikasi (TIK), dengan fokus pada Internet of Things (IoT). Selama empat sesi, workshop ini memberikan pengalaman praktis kepada peserta tentang sistem pengendalian dan pemantauan tandon air menggunakan mikrokontroler ESP32, sensor level air, sensor jarak laser, serta komunikasi data berbasis MQTT. Siswa-siswi dilibatkan secara langsung dalam proses merancang, membangun, dan menguji sistem kendali air yang berbasis IoT. Dari kegiatan ini, dihasilkan dua set alat “Kendali Tandon Air” yang dapat digunakan, buku panduan, dan peningkatan yang signifikan dalam minat serta pemahaman peserta tentang teknologi IoT. Hasil evaluasi melalui kuesioner menunjukkan bahwa peserta merasa puas, dan pihak sekolah sangat mendukung jika kegiatan serupa diadakan lagi di masa yang akan datang.

Abstract

Accurate classification of chest X-ray (CXR) images is vital for early detection of thoracic diseases such as COVID-19, Tuberculosis, and Pneumonia, particularly in regions with limited radiological expertise. While deep learning has shown promise in CXR interpretation, many existing models rely solely on internal datasets, risking overfitting and poor generalizability. Furthermore, inadequate tuning of network architectures may limit robustness across varied imaging conditions. This study presents an externally validated deep learning framework based on Convolutional Neural Networks (CNNs) for multi-disease CXR classification. This study compared a baseline CNN with two convolutional layers against a tuned architecture with three layers across multiple image resolutions (64×64, 112×112, 224×224). The proposed model employs transfer learning with a pre-trained CNN, fine-tuned for four-class classification using a softmax output layer. Training was performed with the Adam optimizer (learning rate: 0.0001, batch size: 32) and categorical cross-entropy loss, for up to 50 epochs with early stopping. Internal validation showed the tuned model outperformed the baseline, achieving 0.97 accuracy and an F1-score of 0.89. External validation confirmed superior generalizability, with the tuned model attaining an F1-score of 0.83 and an AUC of 0.97 at 112×112 resolution, compared to the baseline’s F1-score of 0.79 and AUC of 0.94. These results highlight the potential of optimized CNN architectures as reliable, scalable tools for radiological decision support in resource-limited healthcare systems. Future work will incorporate explainable AI methods and real-world clinical validation to ensure safe, interpretable deployment.

Abstract

Electroencephalogram (EEG) signals are highly susceptible to noise artifacts such as muscle activity, eye blinks, and power-line interference, which degrade signal quality and analysis accuracy. Digital filtering is therefore essential to preserve the EEG frequency band of interest (0.5–40 Hz) while suppressing unwanted components. This study presents a systematic comparison of Finite Impulse Response (FIR) and Infinite Impulse Response (IIR) filters for EEG signal denoising. FIR filters were implemented using Hamming, Hann, and Blackman window methods, whereas IIR filters included Butterworth, Chebyshev type I, Chebyshev type II, and Elliptic designs. All filters were applied to the same EEG signal under identical conditions. Performance was evaluated using visual inspection and Signal-to-Noise Ratio (SNR) analysis, followed by pole–zero stability assessment of the best-performing filters. The results show that FIR filtering achieved a higher SNR improvement (11.0 dB) than IIR filtering (8.61 dB), indicating superior noise suppression and stability for EEG signal processing.

Abstract

This study presents the design and implementation of an integrated Internet of Things based weather monitoring and flood early warning system. The system simultaneously monitors temperature, humidity, rainfall intensity, and water level in real time using a NodeMCU ESP8266 microcontroller integrated with DHT11, rain, and ultrasonic sensors. Experimental results show that the system successfully classifies environmental conditions, where temperatures below 25 °C and humidity levels above 80% indicate heavy rainfall, while rainfall sensor values range between 2000–3000 ADC units. Water-level testing demonstrates that the early warning buzzer is activated when the water level reaches a minimum threshold of 5 cm and remains active below 10 cm, indicating potential flood conditions. Sensor data are transmitted reliably in real time via the MQTT protocol and visualized on a monitoring dashboard without significant delay. These results confirm that the proposed system provides accurate environmental monitoring and effective early flood warning, offering a low-cost and practical solution for flood disaster preparedness.
