Abstract

Kelebihan dari generator bebas energi adalah dapat menghasilkan energi listrik tanpa penggunaan bahan bakar sehingga cocok digunakan di tambak. Generator bebas energi dirancang dengan menggunakan motor listrik dengan daya 1,5 HP dan kecepatan putaran 1480 rpm, generator listrik dengan daya 3 KW dan kecepatan putaran 1500 rpm, dan flywheel dengan massa 36 kg dan diameter 40,6 cm. Hasil pengujian menunjukkan generator dapat menghasilkan tegangan 230 V dengan menggunakan diameter pulley pada flywheel sebesar 12,5 cm, momen inersia yang dihasilkan sebesar 0,74 kg.m2, energi kinetik sebesar 8889,25 Joule, dan daya listrik sebesar 2,4 KW dalam kondisi stabil atau tanpa perubahan.

Abstract

Microbubble generator (MBG) is one of aerator that used to enhance dissolved oxygen (DO). Microbubble generator is designed with the diameter of 45 mm for water inlet and reduced to the diameter of 10 mm. The air inlet has the diameter of 18 mm and increased to 45 mm so that it can be equal with the nozzle diameter. The nozzle is the outlet of water and air is reduced to the diameter of 22 mm. The test results showed that the minimum DO measured of 6.3 mg/l, and the maximum of 6.9 mg/l. The increase in DO ranged from 2.3 – 2.7 mg/l. The measured electric motor temperature ranged from 45°C - 55°C for 9 days of testing so that it can be stated that the microbubble generator can be used for 1 cycle of aquaculture.
