Design and Implementation of a Smart Auto Feeder Fish System Based on Fish Age and Size Using Fuzzy Logic Method
Main Article Content
Abstract
Catfish farming plays a vital role in supporting food security and the economy in Indonesia. However, feed efficiency remains a major challenge as feed accounts for up to 40% of production costs. This study aims to design and implement a Smart Auto Feeder Fish system based on Fuzzy Sugeno logic to optimize feed distribution according to fish age and size. The system uses an ESP32 microcontroller, RTC DS3231, HX711 load cell, keypad, LCD, and three servo motors. The Sugeno fuzzy method determines feed quantity using linguistic inputs of age and size. Testing shows average feeding latency of 1.27 seconds (morning) and 1.73 seconds (afternoon), with feed accuracy reaching 98.12% and 97.47%, respectively. The system was tested in two ponds with 250 fish each. The pond with the system achieved a higher survival rate (75.60%) compared to the control pond (70.40%) and showed more linear growth patterns. The Smart Auto Feeder proves effective in improving feed efficiency, fish growth, and survival rates through automated and adaptive feeding.
