Abstract

Kebutuhan akan energi listrik yang terus meningkat di Indonesia menuntut adanya solusi inovatif yang ramah lingkungan, salah satunya adalah dengan memanfaatkan energi surya. Kegiatan pengabdian Thematic Community Service Collaboration (TCSC) bertujuan untuk memberikan pelatihan penggunaan panel surya sebagai pembangkit listrik tenaga surya di Sekolah SMP Muhammadiyah 3 Medan dengan fokus kepada perancangan PLTS sederhana  sebagai pelatihan penerapan teknologi tepat guna dengan skala pembelajaran. Metode yang digunakan dalam Pengabdian ini yaitu metode ceramah dilanjutkan dengan metode diskusi dan tanya jawab dilanjutkan dengan metode demonstrasi alat beserta cara kerjanya dan metode interaksi langsung yaitu siswa dan guru dapat mencoba atau mempraktikkan secara langsung. Kegiatan Pengabdian ini memiliki tahapan kerja, dimulai tahap melakukan survei sampai tahap evalusi agar kegiatan Pengabdian sesuai target, yaitu menambah pengetahuan, ketrampilan dan kreatifitas guru dan siswa terhadap perkembangan teknologi berupa penerapan panel surya sebagai pembangkit listrik tenaga surya dalam mendukung program hemat energi.

Abstract

Computer keyboards serve as essential input devices that translate user actions into digital signals. One common failure mechanism in keyboard membranes involves broken or degraded circuit traces, which leads to non-functional keys. This study investigates the restoration of such traces using conductive silver paste. An experimental approach was adopted, involving the repair of damaged traces on flexible membrane keyboard PCBs, followed by electrical testing and durability observation. The measurement outcomes indicate that silver paste offers approximately 7% higher electrical conductivity relative to copper, with measured resistivity at 15.87 nΩ·m and thermal conductivity reaching 430 W/m·K. Open circuit conditions (infinite resistance) were successfully restored to functional conductive paths showing 3.5 ± 0.8 Ω resistance after paste application and controlled heat curing. The post-repair resistance represents only a 25% increase compared to the original intact trace value of 2.8 ± 0.5 Ω, which remains well within the acceptable range for digital keyboard applications. This research contributes practical guidance for computer hardware maintenance personnel and researchers focused on input device reliability, while also supporting sustainable practices through repair-based lifecycle extension
