The volume of bioflocs is a crucial factor in developing successful fish farming. The research for supporting food security is an exciting deal. Nevertheless, the use of sedimentation cones for bioflocs volume measurement takes quite a long time. Optoelectronics [1] is one of the efficient ways to measure bioflocs volume quickly. The scattering of light principle is applied to solve this task. Straight light sources such as lasers and photodiodes as light sensors are utilized in this activity in collaboration with a microcontroller. The Imhoff cone cup validates this proposed optical method both in catfish and tilapia fishponds. This research aims to build an efficient technique to measure bioflocs fast by the optoelectronics method. The validation results of bioflocs measurement by sedimentation cone cap showed that this proposed method has outstanding results. But its results tend to be non-linearity. The measured volume of biofloc in tilapia ponds is smaller than that of catfish. In addition, the experiment proved that the less particulate matter in a liquid, the lighter scattering beams would be forwarded. Saving time is improved in this proposed technique than the conventional sedimentation method.
