Energi surya merupakan sumber energi terbarukan yang potensial, namun efisiensi sistem fotovoltaik (PV) sangat dipengaruhi oleh variasi iradiasi, temperatur, dan beban. Penelitian ini mengusulkan sistem Maximum Power Point Tracking (MPPT) berbasis Fuzzy Logic Control (FLC) yang diintegrasikan dengan konverter Buck–Boost untuk mempertahankan operasi panel surya pada titik daya maksimum secara adaptif. Prototipe dibangun menggunakan modul PV 50 Wp, sensor INA219, dan mikrokontroler 8-bit sebagai pengendali utama. Hasil pengujian menunjukkan efisiensi pelacakan daya di atas 97 %, steady-state error di bawah 2,2 %, serta peningkatan daya hingga 106 % dibanding sistem direct coupling. Sistem juga menunjukkan respon cepat dengan waktu konvergensi hanya 5–6 iterasi dan osilasi daya yang minimal. Integrasi FLC dan konverter Buck–Boost terbukti meningkatkan kestabilan dan efisiensi sistem PV terhadap variasi beban maupun kondisi lingkungan, sehingga efektif diterapkan pada sistem energi surya adaptif berskala lebih luas.
