Abstract

Telah dirancang sebuah alat ukur kelajuan dan arah angin. Rangkaian elektronik alat ukur terdiri dari rangkaian catu daya, rangkaian mikrokontroler dan LCD, rangkaian schmitt trigger dan rangkaian fotodioda. Baling-baling pada alat berupa sistem tiga mangkuk. Bagian mekanik alat terbuat dari material ringan, sehingga dapat mengoptimalkan gerakan rotasi mangkuk. Mangkuk terbuat dari bahan plastik yang berdiameter 7,7 cm, sedangkan piringan sensor merupakan cakram CD yang bermassa 20,64 g. Bagian mekanik alat memiliki karakteristik 1 kali pulsa (1 kali putaran) dalam 1 detik (frekuensi = 1 Hz) mewakili kecepatan angin sebesar 0,61m/s. Standardisasi alat dilakukan dengan pengujian terhadap anemometer Lutron AM-4206, ketepatan pengujian sebesar 99,10%, sebagai pembanding, dilakukan juga pengujian antara anemometer mangkuk permanen di BMKG dengan anemometer Lutron AM-4206, ketepatan pengujian sebesar 90,47%. Penentuan arah angin menggunakan sebuah bilah yang akan berputar untuk menentukan 8 arah angin dengan resolusi sebesar 450.
