Abstract

Public Street Lighting (PSL) is essential for road safety at night. A common issue is the lack of routine inspections, leading to potential hazards. Most maintenance still relies on manual on-site visits. This study proposes an automated PSL system using Long-Range (LoRa) communication and a web-based platform to enhance efficiency and monitoring. The system enables optimized brightness control and scheduling, conserving energy and reducing environmental impact. Real-time monitoring and cloud-based data storage allow remote management via a centralized control system. Motion detection and automated lighting adjustments enhance security, while a user-friendly web interface simplifies issue identification and troubleshooting. This system is expected to improve energy efficiency, environmental sustainability, and public safety. Additionally, a placement strategy based on a predefined scheme is necessary for effective implementation.

Abstract

In this decade, Orthogonal Frequency Division Multiplexing (OFDM) technology has been widely applied in various modern wireless communication systems.  OFDM is used to provide high-speed data transmission that is resistant to multipath interference and offers relatively high spectrum efficiency. In this study, an OFDM system prototype equipped with a Huffman Encoder and Decoder, Convolutional Coder, and Viterbi decoder was developed. The OFDM system that has been created is implemented using a Universal Software Radio Peripheral (USRP) device to transmit image data. From the test results, it was found that the OFDM system that has been created and implemented using USRP is capable of transmitting image data well. From visual observation, there were no errors in receiving the transmitted image data. The image received at the receiver was the same shape and size as the image transmitted by the transmitter. The received image was clear, with no image defects such as scratches or mosaics at the measurement distance. A Signal to Noise Ratio (SNR) of more than 30 dB was obtained under line of sight conditions with a measurement distance of 60 cm between the transmitter and receiver. The SNR decreased gradually with increasing measurement distance, reaching approximately 27 dB at a measurement distance of 300 cm between the transmitter and receiver.

Abstract

Keterlibatan verbal anak usia dini pada kegiatan pembelajaran di KB-TK Cita Mandiri masih terbatas karena minimnya media interaktif berbasis teknologi yang mendorong partisipasi aktif anak. Pengabdian kepada Masyarakat (PKM) ini bertujuan mengimplementasikan media pembelajaran digital berbasis interaksi suara dalam kegiatan pembelajaran di KB-TK Cita Mandiri, Surabaya. Sasaran kegiatan adalah anak usia 2–5 tahun (n=10) dan guru pendamping (n=5). Metode pelaksanaan mencakup sosialisasi program, penerapan media, pendampingan dan evaluasi, serta observasi perilaku anak pada dua titik waktu (T1 dan T2) dan evaluasi penerimaan-usabilitas media oleh guru menggunakan instrumen Technology Acceptance Model (TAM) dan System Usability Scale (SUS) yang dilaksanakan pada hari terpisah dari sesi implementasi. Hasil observasi menunjukkan tingkat keterlibatan anak yang tinggi sejak awal sesi dan relatif terjaga hingga akhir sesi (rata-rata skor T1=4,58 menjadi T2=4,67 dari skala 1–5). Guru menunjukkan penerimaan yang positif terhadap media (rata-rata skor TAM=4,98 dari skala 1–5) dengan tingkat usabilitas tergolong sangat baik (rata-rata skor SUS=91,5). Kegiatan ini menunjukkan bahwa media pembelajaran digital berbasis interaksi suara dapat diterima dengan baik dan mendukung keterlibatan belajar anak di lingkungan PAUD.
