Abstract

Penelitian ini bertujuan merancang, memfabrikasi, dan menguji sistem pemanfaatan buangan udara panas (exhaust fan) sebagai sumber energi terbarukan menggunakan turbin angin sumbu horizontal tipe low-speed rotor. Pengujian dilakukan berdasarkan parameter kecepatan aliran udara, temperatur, putaran turbin, tegangan generator, dan daya listrik. Hasil menunjukkan bahwa sistem beroperasi pada kecepatan aliran udara rata-rata 12,69 m/s dan temperatur 33,43 °C. Turbin menghasilkan putaran rata-rata 2.411 RPM dengan tegangan generator 12,3–13,5 V dan rata-rata 12,6 V. Daya listrik aktual mencapai sekitar 250 W, sedangkan perbedaan terhadap nilai teoritis dipengaruhi oleh gesekan mekanik, turbulensi, serta efisiensi generator dan transmisi. Meskipun daya yang dihasilkan masih terbatas, sistem berpotensi memenuhi kebutuhan beban ringan sekaligus meningkatkan efisiensi pemanfaatan energi buangan. Penerapan teknologi ini mendukung konsep industri hijau melalui pengurangan pemborosan energi dan emisi tidak langsung dari energi fosil. Optimasi desain turbin, generator, transmisi, dan aliran udara diperlukan untuk meningkatkan kinerja sistem.
