Hipoksia adalah kondisi berbahaya yangterjadi ketika kadar oksigen dalam darah terlalu rendah,sehingga dapat mengganggu fungsi organ-organ vitalseperti otak dan jantung. Mendeteksi gejala hipoksiasecara dini sangat penting untuk mencegah terjadinyakomplikasi yang lebih serius. Penelitian ini bertujuanuntuk merancang dan menerapkan sistem deteksi gejalahipoksia berbasis Internet of Things (IoT) secara realtime. Sistem ini menggunakan sensor MAX30100 untukmengukur kadar oksigen (SpO₂) serta detak jantung.Data yang dihasilkan dikirim ke aplikasi Blynk melaluimikrokontroler ESP8266, sehingga pengguna dapatmemantau kondisi kesehatannya langsung darismartphone. Sistem ini juga dilakukan uji coba denganWireshark untuk mengevaluasi kinerja jaringan,termasuk analisis terkait delay, jitter, dan packet loss.Hasil uji coba menunjukkan bahwa sistem mampumendeteksi perubahan kadar oksigen dan detak jantungdengan akurasi tinggi dan mengirim data secara real-timedengan delay yang rendah. Sistem ini diharapkan dapatmembantu pengguna memantau kondisi tubuh secaramandiri serta memberikan peringatan dini bila terjadigejala hipoksia.

Visually impaired students in Banyumas face significant challenges in accessing inclusive education due to the scarcity of adaptive learning media. Most students rely heavily on conventional Braille and constant teacher assistance, which hinders their independent learning capabilities. This community service aims to empower teachers and students at SLB Kuncup Mas Banyumas through the socialization and training of BraillTek, a bilingual RFID-based assistive device designed to support independent literacy. The method employed was a participatory approach involving 30 participants, consisting of teachers and students. The activities were conducted on December 9, 2025, encompassing socialization of disability rights, direct demonstration of the device, and hands-on training where students practiced using BraillTek while teachers were introduced to AI-based educational tools. The results indicated high program effectiveness, with evaluation data showing that 100% of participants agreed the material was highly relevant to their needs. Students demonstrated the ability to operate the device independently after a single session, effectively learning vocabulary without constant supervision. The program successfully introduced a viable solution for inclusive education, significantly reducing student dependence on teachers and improving teacher competency in utilizing assistive technology.

Breast cancer remains a major global health concern; therefore, early detection plays a crucial role in reducing its mortality rates. Conventional imaging techniques, such as mammography, have limitations including ionizing radiation exposure and reduced sensitivity in dense breast tissues. Microwave-based sensing has emerged as a promising alternative due to its non-ionizing nature, relatively low cost, and sensitivity to dielectric property contrasts between normal and malignant tissues. This study aims to investigate the effect of phantom orientation angle on the response of an antenna-based microwave sensor for abnormal breast tissue detection. An agar-based homogeneous breast phantom is utilized, with tumor inclusion modeled as regions of different dielectric properties. Measurements are conducted using a Vector Network Analyzer (VNA) over a frequency range of 2–6 GHz, with four orientation angles (0°, 90°, 180°, and 270°). The reflection coefficient (S11) is analyzed to observe variations in electromagnetic response under different conditions. The results indicate that tumor presence causes measurable shifts in resonance frequency and variations in the reflection coefficient (S11). Larger tumors produce greater frequency shifts due to higher dielectric contrast. Furthermore, the orientation angle significantly affects detection sensitivity, which is attributed to the antenna radiation pattern and spatial interaction between electromagnetic waves and the phantom. In conclusion, this study demonstrates that both tumor size and phantom orientation influence antenna sensor response. The novelty of this work lies in the incorporation of orientation-based analysis, providing new insight into spatial electromagnetic interactions and enhancing the potential of microwave sensing systems for accurate and non-invasive breast cancer detection.

Individuals with physical disabilities, particularly those with impaired hand function, require assistive devices that can support daily activities independently. However, the development of prosthetic hands is often constrained by high costs, complex control systems, and limited accessibility of affordable technology. This study aims to design and implement an ESP32-based prosthetic hand with a real-time wireless control system that is simple, stable, and cost-effective. The proposed system employs an ESP32 and Arduino Uno as controllers, a hall effect linear sensor integrated in an electric bicycle throttle as the control input, and servo motors as finger actuators. System performance was evaluated through servo angle accuracy tests, object grasping and lifting experiments, and Quality of Service (QoS) analysis of wireless communication using Wireshark. Experimental results indicate that the system accurately follows commanded servo angles, successfully grasps objects with diameters ranging from 5.5 cm to 12 cm, and lifts loads up to 500 ml at heights between 10 cm and 50 cm. QoS evaluation conducted over 19,150 seconds shows a throughput of 1,737.59 kbps, an average delay of 4.572 ms, jitter of 4.571 ms, and zero packet loss, demonstrating fast and stable real-time communication. These results confirm that the developed prosthetic hand is responsive and functional, and has strong potential for further development as an affordable IoT-based assistive technology for individuals with physical disabilities.
