Abstract

Pengotan Village is geographically located at an altitude of 800 – 1100 m with an average temperature of 28°C . Problems faced in the provision of forage feed is the fluctuating forage production during the rainy and dry seasons, so the quatity and quality of forage that offering is hard to fulfill to ruminant especially bali cattle. Diversification of forage for ruminants is needed to: 1) overcoming the obstacle of forage availability due to limited land for cultivation of forage feed, 2) improve the forage quality through combination of grass and legumes as a source of forage, so that the nutritional needs of ruminants can be met, and 3) reduce the influence of antinutritional on certain forages through diversification of forage because it could be the limiting factor if given in excessive amount to ruminant especially bali cattle. Methods of activities carried out through counseling and discussion, making demoplot forage and seed deployment especially introduce grass and legum to be developed in Pengotan Village. The service was attended by 18 participants and attended by representatives from the village office, socialization and counseling were carried out on the diversification of forage sources to increase the availability and quality of forage feed. In the service activity, demonstration plots for planting forage and dissemination of forage such as dwarf elephant grass (Pennisetum purpureum cv. Mott), Clitoria ternatea and Centrosema pubescens which were carried out together with farmers. Keywords: forage diversification, grass, leguminose, bali cattle

Abstract

The productivity of tilapia is influenced by the rate of growth of fish and the dilution of fish, as well as the feed used during the cultivation process. The use of biofloc techniques greatly affects the growth rate and dilution of fish and can reduce feed costs. Biofloc is composed of floc-forming microorganisms that utilize feed residues and fish feces so that they become natural feed with the help of decomposing bacteria. The use of biofloc can increase fish growth because biofloc can provide natural feed. Such additional (natural) feed has a protein source that serves to increase the growth of farmed fish. In addition, to feed, an important thing to increase the productivity of tilapia is disease prevention. This activity has been carried out on Saturday, August 13, 2022 at the Mina Tirta Pertiwi Pokdakan, Gunung Salak Village, East Selemadeg District, Tabanan. This activity was attended by group members, Fisheries Extension Officers from the Fisheries Service of Tabanan Regency, service teams and resource persons as well as students. This service activity has been carried out well and the team aided in the form of tilapia fry and tools and materials for making biofloc. The hope of this activity is that group members continue to apply the knowledge that has been obtained so that they can increase the production of tilapia.
