In fish farming, approximately 60%-80% of the expenses are allocated to purchasing fish feed. However, currently, fish-feeding practices mostly rely on conventional methods based on human intuition or estimation, which can lead to inadequate feeding that does not meet the fish's actual requirement (around 75% of fish food is wasted). Based on the author's description above, the final project book is here to overcome that problem. This final project book contains the design, implementation, and testing of the controller, interface, and power supply from a smart fish feeder product. The smart fish feeder is a product that can automatically and manually give fish feed to the fishpond. When automatic mode fish feeding is active, the amount of fish feed given by the product will equal 3% of the total fish mass in the pond using second-order polynomial regression. The design and testing for each subsystem are carried out separately. After each subsystem can do each functionality, the integration process will be done into a single unit. The controller subsystem is done by uploading programming codes to the ESP32 microcontroller and ensuring that the microcontroller can still run the program's complexity. The interface subsystem is done by building a mobile app using the MIT App Inventor platform. The power supply subsystem can take electricity from the grid using adapter 12V 10A. The product can fulfil the specifications and solve the problem of reducing the amount of wasted fish feed. However, there are still many things to do to improve the algorithm's accuracy for predicting the amount of fish feed given to the fishpond, such as providing water pH, dissolved oxygen, temperature, and many others on the algorithm.
