Abstract
Sistem akuisisi data cuaca pada prototype buoy weather type II bertujuan untuk memprediksi cuaca secara realtime. Instrumen di dalam buoy weather membutuhkan daya listrik agar pengambilan data bisa berjalan. Sumber daya yang mandiri dan dapat diperbaharukan dibutuhkan sebagai media penyuplai peralatan instrumen. Photovoltaic menjadi pilihan utama sebagai media penyuplai peralatan instrumen dan baterai sebagai media catu daya cadangan disaat photovoltaic tidak dapat memproduksi energi. Konversi energi dari photovoltaic tidak efisien karena tidak selalu bisa mengikuti titik MPP photovoltaic dan hanya bisa memberikan efisiensi daya maksimum sebesar 30.70% terhadap beban instrument buoy weather. Diperlukan synchronous buck converter dengan metode logika fuzzy untuk mendapatkan daya dengan efisiensi tinggi. Dengan cara pengukuran variasi irradiansi sebagai parameter input dan lampu 90 watt sebagai beban, maka didapatkan daya maksimal sebesar 78.83 watt dan efisiensi 87.3% terhadap beban, serta mengalami peningkatan efisiensi daya rata-rata sebesar 225.43%. Nilai duty cycle yang dibutuhkan untuk converter bekerja dari 10% - 80% dengan logika fuzzy bekerja sebagai penentu keputusan

Weather data acquisition system at the weather buoy prototype type II aims to predict the weather in realtime. Instruments at the weather buoy requires electrical power so that acquisition data could work. Independent resource and renewable supplies equipment needed as a medium of instruments. Photovoltaic be the primary choice of media equipment supplies instruments and batteries as a backup power supply when the media is unable to produce energy anymore. Photovoltaic energy conversion is inefficient because it is not always able to follow the photovoltaic MPP point and can only give a maximum power efficiency of 30.70 % based on instrumentation electrical load. Required synchronous buck converter with fuzzy logic methods to gain power with high efficiency. By measuring variations irradiance as an input parameter and DC lamp as a 90 watt electrical load, then obtained a maximum power of 78.83 watts and 87.3 % efficiency, then average power incrase to 225.43%. Rated duty cycle required for the converter to work from 10 % - 80 % with fuzzy logic works as a determinant of decision
