Abstract
Pada sektor pertanian, khususnya bagian irigasi diperlukan pompa air bertenaga listrik. Akan tetapi, masih banyak daerah yang sulit untuk mendapatkan listrik dari jala-jala PLN sehingga diperlukan sumber listrik bertenaga surya yang dapat menjadi solusi masalah tersebut. Motor yang digunakan sebagai penggerak pompa air ialah motor BLDC karena karakteristiknya yang memiliki efisiensi, torsi start, kecepatan yang tinggi. Selain itu, lifetime yang panjang, perawatan yang mudah, dan keandalan yang tinggi juga menjadi alasan dipilihnya motor ini. Pada pengaplikasiannya di irigasi, pompa air rentan untuk terkena cuaca yang bertemperatur tinggi. Cuaca seperti ini berpotensi mengurangi performa dari motor BLDC dengan sensor hall effect sehingga digunakan jenis sensorless. Selain itu, untuk mendapatkan sistem yang lebih compact, akan digunakan sistem single stage yang mengurangi penggunaan konverter DC. Dengan demikian, penelitian ini merancang sistem pompa BLDC tenaga surya dengan konfigurasi single stage guna meningkatkan efektifitas dari sistem di cuaca bertemperatur tinggi. Hasil dari simulasi menunjukkan pompa air dapat bekerja tanpa riak yang tinggi dengan kecepatan minimal 1100 RPM dan pada kondisi steady state MPPT dapat beroperasi dengan keefektifan 99,85%. Kecepatan optimum dari motor juga dapat dikontrol berdasarkan penyesuain kondisi cuaca dari duty cycle (D) yang dihasilkan oleh operasi MPPT dengan konfigurasi satu tahap.

Electrical powered water pumps are essential in the agricultural section, particularly in irrigation. However, many areas in Indonesia still face challenges in accessing electricity from the national grid, making solar-powered electricity a potential solution to address this issue. BLDC motors are used as the driving force for water pumps due to their characteristics, which include high efficiency, starting torque, and speed. Additionally, their long lifespan, ease of maintenance, and high reliability make them the preferred choice. In irrigation applications, water pumps are susceptible to high-temperature weather conditions. Such weather can reduce the performance of BLDC motors that use hall effect sensors, making sensorless types more suitable. Furthermore, to achieve a more compact system, a single-stage system will be employed, minimizing the need for DC converters. This study designs a solar-powered sensorless BLDC pump system with a single-stage configuration to improve system effectiveness under high-temperature weather conditions. Simulation results show the minimum speed at which the water pump can operate without significant ripple is 1100 RPM. Under steady-state conditions, MPPT system can operate up to 99,85% of effectiveness. The motor's optimal speed can also be controlled based on weather conditions through the duty cycle (D) generated by MPPT operation using the single-stage configuration.
