Abstract
Microbubble Generator merupakan salah satu alat yang digunakan untuk sistem aerasi dan dapat menghasilkan microbubble. Microbubble ini lebih tahan dalam air karena memiliki kecepatan slip yang rendah. Dalam penelitian ini dilakukan perancangan dan pengujian peforma Microbubble Generator tipe orifice-porous tube. Penelitian ini bertujuan untuk mendapatkan rancangan Microbubble Generator yang efisien, distribusi microbubble melimpah, tingkat kelarutan oksigen dalam air tinggi, serta kebutuhan daya kecil. Dalam penelitian ini dilakukan pengujian terhadap 3 rancangan Microbubble Generator tipe orifice-porous tube yaitu dengan diameter orifice 6 mm, 8 mm, dan 10 mm, serta dengan menggunakan variasi debit udara 0,1 lpm 0,4 lpm, dan 0,8 lpm. Hasil dari penelitian ini menunjukkan bahwa Microbubble Generator yang dirancang kurang mampu mengkonfirmasi bahwa yang dihasilkan adalah gelembung micro. Parameter-parameter yang diujikan secara signifikan memberi pengaruh terhadap jumlah dan ukuran microbubble. Semakin besar debit udara yang diberikan maka semakin semakin besar ukuran bubble. Diameter orifice yang semakin kecil maka akan mengakibatkan semakin banyak bubble yang dihasilkan dan ukuran bubble yang semakin kecil.

Microbubble Generator is one of the tools used for aeration systems and can produce microbubbles. This microbubble is more resistant in water because it has a low slip speed. In this study, the design and performance of the Microbubble Generator was designed for the orifice-porous tube type. This study aims to obtain an efficient Microbubble Generator design, abundant microbubble distribution, high oxygen solubility in water, and low power requirements. In this study, testing was carried out on 3 designs of orifice-porous tube type Microbubble Generator, namely with orifice diameters of 6 mm, 8 mm, and 10 mm, and by using variations in air discharge 0.1 lpm, 0.4 lpm, and 0.8 lpm. The results of this study indicate that the designed Microbubble Generator is less able to confirm that the resulting microbubbles are. The tested parameters significantly influence the number and size of microbubbles. The greater the flow of air given, the larger the bubble size. The smaller the orifice diameter will result in more bubbles being produced and the bubble size getting smaller.
