Abstract

Kegiatan Pengabdian Kepada Masyarakat (PKM) ini bertujuan mentransfer teknologi pembuatan alat bantu informasi lokasi berbasis sensor Passive Infra-Red (PIR) untuk meningkatkan kemampuan orientasi dan mobilitas (O&M) Penyandang Disabilitas Sensorik Netra (PDSN) di SLBN-A Citeureup, Kota Cimahi. Proses pelaksanaan dilakukan melalui perancangan dan pembuatan prototipe berbasis mikrokontroler Arduino Nano yang menghasilkan keluaran suara melalui modul DFmini Player, dilanjutkan dengan pelatihan alih teknologi kepada guru dan teknisi sekolah, serta pengujian kinerja perangkat menggunakan uji teknis dan evaluasi pengguna. Hasil pengujian menunjukkan bahwa perangkat mampu merespons dalam waktu 1,2 sampai 1,5 detik dengan akurasi deteksi 91,2%, jangkauan efektif 0,7 sampai 2 meter, dan tingkat kejernihan suara 70 dB, sementara evaluasi alih teknologi memperlihatkan peningkatan kompetensi mitra dengan 100% peserta memahami instalasi, 85% mampu memperbarui file suara, dan 80% dapat menyesuaikan sensitivitas sensor secara mandiri. Konsistensi hasil tersebut diperkuat oleh penilaian pengguna melalui kuesioner yang menghasilkan skor rata-rata 4,7 (skala 5), yang menunjukkan bahwa perangkat bekerja secara efektif, mudah dioperasikan, dan bermanfaat dalam membantu identifikasi lokasi ruang bagi PDSN. Dengan demikian, teknologi ini terbukti layak diimplementasikan sebagai perangkat Teknologi Tepat Guna (TTG) dan memiliki potensi replikasi lebih luas di lingkungan pendidikan khusus.

Abstract

Digital transformation in education requires teachers to effectively utilize technology as a medium for collaboration and professional development. This community service program aims to enhance the competencies of elementary school Physical Education (PE) teachers in implementing the Lesson Study and Project-Based Learning (PjBL) approaches through the integration of Trello as a digital discussion forum. The program was conducted through several stages: socialization, training, mentoring, technology implementation, evaluation, and program sustainability, involving 36 participants from the Elementary School PE Teachers Working Group (KKG PJOK) in Banjarbaru. Trello was implemented to facilitate lesson planning, peer observation, reflection, and collaborative task management. Evaluation was carried out through pre-tests, post-tests, and observations of collaborative learning activities. The results showed a significant improvement in participants’ understanding of the Lesson Study stages and the implementation of PjBL, with more than 90% of participants able to identify the Lesson Study phases, relevant Trello features, and product-based PjBL assessments. These findings indicate that the use of Trello can enhance digital literacy, collaborative skills, and teachers’ readiness to apply innovative learning practices. The program is recommended to be continued and further developed as a sustainable professional development model for PE teachers in the digital era.

Abstract

The increasing demand for portable and energy-efficient electronic devices has driven innovation in smartphone charging technology. Continuous smartphone operation requires an efficient power source, especially when AC power is unavailable. This study presents the design and implementation of a microcontroller-based DC-to-DC Buck Converter for smartphone charging using a 12V DC input. The system employs a MOSFET as a switching device controlled by PWM signals generated by an ATMega16 microcontroller. By adjusting the PWM duty cycle, the microcontroller regulates the output voltage to meet different smartphone charging requirements.The converter steps down the 12V DC input to a lower, stable voltage suitable for mobile phone charging while maintaining high efficiency. Essential circuit components, including the microcontroller, MOSFET, inductor, and capacitor, are arranged to ensure smooth voltage conversion with minimal ripple. Experimental results confirm that the designed converter effectively produces adjustable voltage levels compatible with various smartphones.Overall, this system demonstrates a reliable and energy-efficient solution for DC-powered smartphone charging, offering flexibility for use in portable and off-grid conditions.
