Abstract

Peningkatan penggunaan bandwidth dalam teknologi jaringan diharapkan sebagai hasil dari semakin banyaknya orang yang menggunakan jaringan berkecepatan tinggi dan jalur data yang lebih luas. Oleh karena itu, hal ini memiliki dampak yang lebih besar pada sejumlah masalah jaringan, termasuk kemacetan, bottlenecking (ketika jalur data dibanjiri lebih banyak input daripada yang dapat ditanganinya), dan penundaan antrian. Metode awal dalam penelitian ini dengan membaca studi literatur. Penelitian ini merupakan penelitian ekperimen dengan mengukur kinerja modul nRF24l01 sebagai perangkat komunikasi dalam melakukan pengiriman data. Pengujian dilakukan dengan dua kondisi, yaitu Line of Sight (LoS) dan Non-Line of Sight (NonLoS). Dengan sink node sebagai penerima data (receiver) dan sensor node sebagai pengirim data (transceiver). Pada kondisi Line of Sight (LoS), hasil pengukuran jitter menunjukkan nilai yang lebih rendah 0.01 dibandingkan kondisi Non-Line of Sight (Non-LoS). Hasil pengukuran packet loss kondisi Line of Sight (LoS) menunjukkan hasil 1.74% lebih baik dibandingkan packet loss. Pengujian Quality of Service (QoS) menunjukkan bahwa kondisi Line of Sight (LoS) memiliki performa yang lebih baik dari kondisi Non-Line of Sight (Non-LoS) karena pada kondisi Non-Line of Sight (Non-LoS) terdapat sebuah halangan yang mengalangi transmisi sinyal dalam melakukan pengiriman data. Kata kunci: Line of Sight, Non-line of Sight, Quality of Service, Wireless Sensor Network

Abstract

Maternal health and fetal growth in rural areas require special attention due to limited access to adequate healthcare systems. Early detection of fetal health conditions can be achieved using B-mode ultrasonography (USG). However, expectant mothers in these regions often lack regular to regular check-up, even when healthcare facilities are available there may not be trained professionals available to analyze the B-mode images obtained in the Community Health Centres. To address this gap, a tele-USG system was developed that allows healthcare workers in remote areas to operate basic USG equipment and transmit real-time images to specialist doctors at higher-level healthcare facilities. During system development, a general-purpose USG phantom was used to test parameters: penetration depth, geometric accuracy, focal zone, and axial and lateral resolution. Testing confirmed that both USG and laptop used for streaming produce reliable and accurate results. A slight geometric representation differences of 2.74% (approximately 1 cm per target) was observed, attributed to dimensional distortion between devices with different monitor sizes. In geometric accuracy tests, five out of eight vertical and six out of seven horizontal targets were successfully detected. The smallest variation of 0.028 mm occurred at 5 MHz frequency, demonstrated high precision focal zone measurements. The axial resolution ranged between 0.25-0.5 mm, while lateral resolution ranged from 1.0-2.0 mm, indicating strong capability for fine-detail imaging. Overall, the system exhibited high sensitivity and excellent imaging performance, offering a promising solution to enhance maternal and fetal healthcare challenges faced by rural communities in Indonesia through accessible real-time diagnostic support
