Abstract

Kebutuhan pengisian daya pada node-node IoT sangatlah penting untuk keberlangsungan sebuah sistem jaringan sensor nirkabel oleh karena itu digunakanlah salah satu cara yaitu transfer daya nirkabel. Sistem transfer daya nirkabel haruslah memiliki sifat keterjangkauan, khususnya di node-node¬ yang berada di area yang sulit dijangkau sehingga terciptanya sebuah Proyek Kolaborasi Pusat ITS yang berjudul “Wahana Nirawak: Aspek Keamanan Data, Pengisian Enerji, dan Desain Antena 26 GHz” yang memfokuskan pada aspek pengisian ke node-node Wireless Sensor Network (WSN) menggunakan Drone sehingga membutuhkan transfer daya yang optimal dan efisien. Dalam Tugas Akhir ini dilakukan kajian dan pengukuran terhadap efisiensi daya yang diterima pada rectenna menggunakan modulasi amplitudo dengan variasi bentuk gelombang meliputi sinusoidal, sawtooth, square, dan triangle. Adapun untuk pengujian akan dilakukan dengan pengukuran secara langsung dan perhitungan yang meliputi parameter daya RF yang diterima (Pin RF), tegangan keluaran DC (Vout DC), dan efisiensi konversi daya RF to DC (η_(RF-DC)) dengan menggunakan perangkat keras SDR HackRF One dan Rectenna serta bantuan perangkat lunak GNU Radio dan HackRF Sweep Spectrum Analyzer. Hasil pengukuran menunjukkan bahwa bentuk gelombang sinusoidal adalah bentuk gelombang yang paling efisien dalam konversi daya RF to DC menggunakan modulasi amplitudo dengan nilai efisiensi sebesar 65.79% pada jarak 40 cm. ================================================================================================ The need of charging at IoT nodes is very important for the sustainability of a wireless sensor network system, therefore one way is used, namely wireless power transfer. Wireless power transfer systems must have affordability, especially in nodes located in hard-to-reach areas, resulting in the creation of an ITS Central Collaboration Project entitled “Unmanned Vehicles: Aspects of Data Security, Energy Charging, and 26 GHz Antenna Design” which focuses on the aspect of charging to the wireless sensor network (WSN) nodes using drones so that it requires optimal and efficient power transfer. In this Final Project, an assesment and measurement of the received power efficiency on the rectenna is carried out using amplitude modulation with various waveforms such as sinusoidal, sawtooth, square, and triangle. As for the tests, direct measurements and calculations will be carried out which include the parameter of received RF power P_(in RF) , DC output voltage V_(out DC) , and RF to DC power conversion efficiency η_(RF-DC) using hardware SDR HackRF One and rectenna with software assistance from GNU Radio and HackRF Sweep Spectrum Analyzer. The measurement results show that the sinusoidal waveform is the most efficient waveform in RF to DC power conversion using amplitude modulation with an efficiency value of 65.79% at a distance of 40 cm.
