Abstract
Pemanfaatan energi angin sebagai sumber energi terbarukan berpotensi tinggi untuk mendukung sistem akuakultur yang lebih efisien dan ramah lingkungan. Penelitian ini bertujuan merancang sistem double wind turbine untuk penggerak aerator dan penyedia listrik sistem autofeeder. Pada bagian penyedia listrik digunakan Rangkaian buck boost converter berbasis kontroler fuzzy logic type-2 dengan input berupa error dan tegangan masukan, serta output Pulse Width Modulation (PWM) yang dirancang dengan metode Sugeno dan Footprint of Uncertainty (FOU) ± 0,1. Hasil pengujian menunjukkan kemampuan konverter menaikkan dan menurunkan tegangan fluktuatif dari generator wind turbine menuju setpoint 15 V, dengan rata-rata daya output 8,23 Watt dan efisiensi 80,85%, menghasilkan energi output rata-rata 0,097 Wh pada pengambilan data per menit selama 24 jam. Uji closed loop buck boost converter mencatat pada mode buck maupun boost didapatkan error steady state ≤ 0,54%, serta Root Mean Square Error (RMSE) 0,501 V pada mode buck dan 0,341 V pada mode boost. Sementara itu, wind turbine yang terintegrasi dengan differential gear mampu menggerakkan aerator untuk meningkatkan kadar Dissolved Oxygen (DO) hingga 0,79 mg/L pada mini plant dan 0,57 mg/L pada kolam ikan yang dimonitor 24 jam menggunakan sensor DO dengan akurasi 99,6%. Hasil ini menunjukkan potensi sistem untuk mendukung efisiensi energi terbarukan sekaligus meningkatkan kualitas lingkungan pada budidaya perikanan.

The utilization of wind energy as a renewable energy source has high potential to support more efficient and environmentally friendly aquaculture systems. This research aims to design a double wind turbine system for driving aerators and providing electricity for autofeeder systems. For the electricity supply component, a buck boost converter circuit based on fuzzy logic type-2 controller is used with inputs of error and input voltage, and Pulse Width Modulation (PWM) output designed using the Sugeno method and Footprint of Uncertainty (FOU) ± 0.1. Test results demonstrate the converter's capability to step up and step down fluctuating voltage from the wind turbine generator to a setpoint of 15 V, with an average output power of 8.23 Watts and efficiency of 80.85%, generating a mean energy of 0,097 Wh based on per-minute data collection over 24 hours. Closed loop buck boost converter testing recorded that in both buck and boost modes, steady-state error ≤ 0.54% were achieved, with Root Mean Square Error of 0.501 V in buck mode and 0.341 V in boost mode. Meanwhile, the wind turbine integrated with differential gear is capable of driving the aerator to increase Dissolved Oxygen (DO) levels by up to 0.79 mg/L in the mini plant and 0.57 mg/L in the fish pond, monitored for 24 hours using a DO sensor with 99.6% accuracy. These results demonstrate the system's potential to support renewable energy efficiency while improving environmental quality in aquaculture.
