Abstract

Feed is the most significant component of tilapia culture production costs. Various attempts have been made to reduce this cost with alternative feed, including A. microphylla. The research aims to encourage changes in the level of knowledge, attitudes, and skills of fish cultivators about utilization and cultivation of Azolla through the demonstration ponds (Dempond) and increase the production of tilapia by increasing the stocking density and the use of A. microphylla feed. The research was conducted from March 2nd to May 15th, 2021, in Panjalu Sub District, Ciamis Regency, West Java Province. Data were collected by purposive sampling, with observation and interview methods. The data consists of primary and secondary data. The data analysis was carried out in a descriptive qualitative manner. The results showed a change in fish cultivators' knowledge about the benefits and cultivation of A. microphylla by an average of 20.28%, a change in target attitudes by 5.1%, and skill improvement by 28%. There was an increase in tilapia yield from the initial total weight of 121.25 kg to 226.1 kg using 24 kg of A. microphylla as a feed additive for 60 days of culture.
