The application of new technology in the form of biofloc technology has been tried in the process of tilapia seed cultivation in Jegu Village, Penebel District, Tabanan Regency, but it is also necessary to study whether the new technology can be implemented sustainably by analyzing it using the SWOT Matrix. This study uses a descriptive method by determining the location by purposive sampling with the consideration that the research site already uses a biofloc system. The results of the SWOT analysis show that the position of cultivators is in quadrant III Turn Around/Stability (Change Strategy) followed by a SWOT matrix based on IFAS (Internal Strategic Factor Analysis Summary) and EFAS (External Strategic Factor Analysis Summary) so that the right strategy is obtained is the WO Strategy namely taking advantage of existing opportunities by improving the internal weaknesses of Mina Ayu group members. So that what needs to be implemented: (1) Cultivators to be able to make maximum use of the capital provided by the capital providing institution, (2) Cultivators to be able to make alternative feeds as a substitute for pellet feed, (3) Cultivators to utilize natural resources that support optimally for increase the number of seeds produced, (4) Cultivators to look for alternative markets other than marketing in Lake Batur to guard against disturbances for cultivators in Lake Batur so as not to interfere with the distribution of the seeds produced, and (5) Cultivators to take advantage of local government policies which supports hatchery activities.

INTRODUCTION Tabanan Regency, which has been known as an agricultural area, has various fishery potentials, both regional potential, natural resources and marine resources. The availability of many springs and river flows that flow throughout the year as well as relatively low-pollution water conditions have encouraged the growth and development of freshwater fishery agribusiness in the form of fish cultivation in ponds, rice fields, irrigation canals as well as the development of fish farming in Jakapung (floating bag net). (Fisheries and Marine Service of Tabanan Regency 2019). Furthermore, the Tabanan Regency Fisheries and Maritime Service (2019) determined that the type of tilapia developed in Tabanan Regency was a superior type of tilapia. Among them are Gift tilapia, Nirvana tilapia, Gesit tilapia and Taiwanese tilapia. Tabanan's tilapia seeds are currently in great demand by jakapung farmers in Lake Batur (Bangli). Meanwhile, consumption of tilapia is mostly absorbed by restaurants in Badung and Denpasar. The center for tilapia development is in Baturiti District (Lake Beratan, Candi Kuning Village), Penebel District (Pentahanan Village, Tengkudak and Pitra), Marga District (Petiga Village, Ole Village), Selemadeg District (Tiying Gading Village), East Selemadeg District (Megati Village). Tilapia is an animal that lives in water which is one of the many food ingredients needed by humans, fish is very useful for humans. It contains various substances needed by the human body such as protein, vitamins, and minerals. As a source of protein there is a composition contained in tilapia. The composition is the chemical composition of tilapia per 100 grams of meat can indicate that tilapia has a fairly low fat (2.7%) and a fairly high protein content of 17.8%
