Water turbidity refers to the concentration of dissolved materials, such as salts or minerals, in the water (Hidayana et al., 2024). The ideal turbidity level varies depending on the species being cultured. Most freshwater fish thrive in water with a turbidity of 1.000 to 1.025 g/cm³, although specific preferences may vary by species. Proper turbidity levels are vital for maintaining buoyancy, regulating oxygen availability, and ensuring overall fish health (Raghavendra et al., 2025; Adjovu et al., 2023).

The main objective of this study is to assess the functionality of the automated fish pond feeding and detection of water turbidity using Arduino UNO. This system aims to eliminate common problems in fishpond culture by improving feeding efficiency, maintaining ideal water quality, and enhancing the health and productivity of cultured fish.
