The determing of language learning strategies that are often used by cadets in the Surabaya aviation polytechnic and knowing the correlation between the age, gender, major and educational background of each cadet are the goals in this reseach. Chi-Square test and Pearson product moment correlations test was used in order to determine whether or not common effect of age, gender, major and educational background of each cadet displayed significant differences on Language Learning Stratrgy of students. The results stated that the most frequently-used strategies were metacognitive strategies. The least frequently-used ones were affective strategies. The results of Pearson product moment correlations revealed that gender were the only demografic factors that were significantly correlated with the learners’ learning strategy. The relationship between learners’ learning strategy and gender was found to be positively significant .002 (sig < .005), learning strategy use associated with gender were significantly correlated.

Rancang Bangun Sistem Pengukuran Keccepatan Putar Generator Pada Turbin Angin Menggunakan Optocoupler Berbasis Mikrokontroler ATMEGA8535 Rifdian I. S.; Hartono Hartono
Jurnal Penelitian 29-35
Publisher : Politeknik Penerbangan Surabaya

Kecepatan angin dan desain sudu mempengaruhi besarnya kecepatan putaran generator, sehingga data kecepatan putar sudu dan kecepatan putar generator menjadi salah satu acuan untuk berbagai keperluan seperti mendesain sudu turbin, data pembanding dengan output generator dalam menentukan kinerja generator dan sistem keamanan turbin. Tujuan dari penelitian ini adalah merancang alat pengukur kecepatan putar (rpm) generator yang dihasillkan dari pergerakan turbin angin. Prinsip kerja dari alat ini yaitu menembakkan cahaya infra merah pada bidang reflektif yang akan memantulkan cahaya inframerah yang kemudian diterima oleh detektor. Alat pengukur kecepatan putar ini menggunakan sensor led inframerah yang dapat memancarkan cahaya inframerah yang tidak kasat mata. Cahaya inframerah merupakan gelombang cahaya yang berada pada spektrum cahaya tak kasat mata yang ditembakkan ke daerah reflektif kemudian ditangkap oleh phototransistor sebagai receiver. Output receiver akan dikonversi dalam bentuk kecepatan putar (rpm) oleh mikrokontroler. Nilai rpm akan ditampilkan melalui display lcd. Berdasarkan hasil pengujian alat diperoleh bahwa error pengukuran paling kecil pada kecepatan 6000 RPM dengan prosentase error sebesar 0.00 %, sedangkan prosentase error terbesar pada kecepatan 500 RPM sebesar 0.04 %. Dari data hasil pengujian yang telah dilakukan , hasil pengukuran masih dalam batas toleransi yaitu sebesar ±10%.
