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

Abstract

Postural stability depends on multisensory integration, yet most studies focus on a single EMG feature or sensory condition at a time. This creates a significant gap in understanding how multiple EMG features change when various sensory inputs are altered during quiet standing. To address this, the present study examined bilateral medial and lateral gastrocnemius activation using five EMG features: Mean Absolute Value (MAV), Root Mean Square (RMS), Waveform Length (WL), Integrated EMG (IEMG), and Total Power (PT) across four sensory conditions that combine visual input (eyes open or closed) and surface stability (stable or unstable). A one-way ANOVA revealed significant condition effects for RMS, MAV, WL, and IEMG (p < 0.05), while PT showed only a non-significant trend. Paired t-test results indicated that MAV significantly increased on the unstable surface with eyes closed compared to the stable surface (t(4) = 4.793, p = 0.009), WL increased in the right lateral gastrocnemius under the same condition (t(4) = 3.976, p = 0.016), and closing the eyes on a stable surface significantly increased WL in the right medial gastrocnemius (t(4) = 6.209, p = 0.003). Across features, the right gastrocnemius consistently showed greater modulation than the left, suggesting dominance-related asymmetry in neuromuscular control. This study provides one of the first bilateral multi-feature EMG characterizations of sensory perturbations during quiet standing. The findings demonstrate that the absence of vision increases neuromuscular demand even on stable surfaces, and that unstable surfaces further amplify activation, particularly in complexity-related features such as WL. These outcomes highlight the potential of EMG features, especially WL, as objective biomarkers for balance assessment. Clinically, the results may inform rehabilitation and fall-prevention programs by supporting the use of unstable surfaces and vision-restricted exercises to enhance proprioceptive and vestibular compensation

Abstract

Kegiatan pengabdian masyarakat ini bertujuan meningkatkan pemahaman dan praktik Cuci Tangan Pakai Sabun (CTPS) sebagai bagian dari Perilaku Hidup Bersih dan Sehat (PHBS) pada siswa kelas 4 dan 5 SDN Cipagalo 3 Bandung melalui pendekatan demonstratif dan penggunaan teknologi tepat guna HygieScan. Kegiatan dilaksanakan melalui beberapa tahapan, mulai dari pemberian edukasi mengenai PHBS dan teknik CTPS, senam cuci tangan sebagai metode interaktif, praktik langsung mencuci tangan, hingga evaluasi kebersihan tangan menggunakan perangkat HygieScan berbasis pencahayaan ultraviolet. Perangkat ini memberikan umpan balik visual yang memungkinkan siswa melihat area tangan yang masih terkontaminasi setelah mencuci tangan. Hasil kegiatan menunjukkan peningkatan keterampilan CTPS pada sebagian besar siswa, yang terlihat dari berkurangnya area bercahaya saat pemindaian kedua. Antusiasme siswa juga tinggi, ditunjukkan oleh banyaknya peserta yang secara sukarela melakukan pemeriksaan ulang. Evaluasi melalui kuesioner kepada guru dan siswa menunjukkan respons sangat positif terhadap metode edukasi yang digunakan, efektivitas fasilitator, serta harapan agar program serupa dilakukan kembali. Sebagai bentuk keberlanjutan, dua unit HygieScan beserta buku manual dan media edukasi dihibahkan kepada pihak sekolah untuk mendukung pemanfaatan alat secara mandiri. Temuan ini menunjukkan bahwa integrasi teknologi sederhana namun interaktif dapat menjadi strategi edukasi yang efektif dalam memperkuat pembiasaan CTPS dan mendukung pencapaian PHBS di Sekolah Dasar.
