Recent research on vannamei shrimp is conducted in various regions due to its high economic value. However, to cultivate vannamei shrimp effectively, special attention must be paid to water quality, and the latest technology must be utilized to support more efficient and effective shrimp farming practices. This study aims to evaluate the impact of using fine bubble diffusers as aerators on water quality and the growth of vannamei shrimp (Litopenaeus vannamei). Fine bubble diffusers are an aeration technology that generates small air bubbles to increase dissolved oxygen (DO) levels in water. The research was conducted using a small-scale experimental method in vannamei shrimp farming ponds, where two ponds were equipped with fine bubble diffusers, while one pond was used as a control with a conventional aeration system (Kandila ECO-1200). Observations were made on several water quality parameters, including DO levels, temperature, salinity, and pH. Additionally, the growth of vannamei shrimp was measured by the average weight of the shrimp at specific intervals. The results showed that the use of fine bubble diffusers significantly increased DO levels compared to the built-in aquarium filter. This increase in DO had a positive impact to the growth of vannamei shrimp. Additionally, the addition of a Fine Bubble Diffuser can also help stabilize the pH in the water. The growth of vannamei shrimp also showed better results in the ponds using fine bubble diffusers, with faster weight gain compared to the control pond. These findings suggest that fine bubble diffusers not only improve water quality but also create a more conducive environment for the growth of vannamei shrimp
