Due to this condition, therefore socialization and demonstration how to place of planting high forages feedstuff (leguminoseae and nonleguminoseae) by Three Forages Stratum System (STS) for planting high quality of forages and practice of biofermentation technology for increasing the rice straw which helps to raise digestion for the livestocks. With this community service program, the expected result is the members of group have knowledge and comprehension that rice straw could be used as source of forages which could be stored within 3 to 4 months with a Microorganisms culture (EM-4) fermentation method.
