Common fishery such as the one in “Pusat Budidaya Perikanan ”, the PKMT team's partner, located RM. Kahfi I, No. 1, Kelurahan Cipedak, Kecamatan Jagakarsa is still conducted its fish feeding activity manually. The feeding process is crucially counting on the man power that spreads the food known as “pelet” directly to the pounds without calculating the amount of the food. For that reason, this PKM T's work tries to build a fish feeding system which is economical, automated and hygienic. As a realization, a miniature of Microcontroller-Based Smart Fish Feeding System with special modified features of automated pelet's timer and its dosage scale has been created. These features can be set in accordance to the wishes since the microcontroller is used as “the system's brain”. It controls the solenoid valve and the DC motor of the pelet storage container to work. Thus, the system can not only measure how much pelet is left but also notify it through a buzzer.
