Pengukuran Kecepatan Angin di Dalam dan Sekitar Model Stasiun Menggunakan Constant Temperature Anemometer


Wind speed measurement around station model is very important to know turbulence flow pattern  that can disturb pedestrian comfort around station. One way to know wind speed is using Constant Temperature Anemometer (CTA) or Hot-Wire Anemoemeter, which is a device used to measure wind speed and turbulence. This paper discusses measurement of wind speed around station with CTA from Dantec to determine distribution of wind speed and turbulence outside and inside station using probe types 55 P14 and 55 P62. From measurement result obtained that maximum speed at all measurement point if connected with Beaufort scale show Beaufort Number 9 is Strong Gale. Description from this wind effect are pedestrians like being blown by wind blows making it uncomfortable.

Pengukuran kecepatan angin di sekitar model stasiun sangat penting dilakukan untuk mengetahui pola aliran turbulen yang dapat mengganggu kenyamanan pejalan kaki disekitar stasiun. Salah satu cara ntuk mengetahui kecepatan angin tersebut dengan menggunakan Constant Temperature Anemometer (CTA) atau Hot-wire Anemometer, yakni satu alat yang digunakan untuk mengukur kecepatan angin dan turbulensi. Makalah ini membahas pengukuran kecepatan angin di sekitar stasiun  dengan CTA dari Dantec untuk mengetahui distribusi kecepatan angin dan turbulensinya di luar stasiun dan di dalam stasiun dengan menggunakan jenis probe 55P14 dan 55P62. Dari hasil pengukuran didapatkan bahwa kecepatan maksimal di semua titik pengukuran jika dihubungkan dengan skala Beaufort menunjukkan Beaufort Number 9 yaitu Strong Gale. Deskripsi dari efek angin ini adalah pejalan kaki seperti ditiup oleh hembusan angin sehingga membuat tidak nyaman.
