Abstract
One of the obstacles in increasing rice production in Indonesia is pests of plant diseases such as the attack of Udbatta diseases caused by Ephelis oryzae. This disease attacks the panicles so that the panicles can not grow and do not produce at all. The current use of biological agents has considerable attention worldwide. This treatment is more popular because of the increased public awareness of biological safety issues and environmental health issues, with respect to phytotoxicity due to the excessive use of synthetic pesticides. Therefore, in this research, developed S. marcecens indigenoes to control the Udbatta diseases. The purpose of this research is to know the ability of S. marcecens indigenoes as biological controlling agents of Udbatta diseases. The test was performed by knowing the production of the extracellular enzyme by S. marcecens indigenoes so that the bacteria could potentially act as plant disease control. The test was done invitro test. From the results of the study it is known that S. marcescens indigenus secretes chitinase, protease and cellulase enzymes. These three enzymes can destroy the fungal cell wall of E. oryzae causing udbatta disease, destroying cellulase and protein, thus potentially as biological agents of Udbatta disease. Inhibition of S. marcescens indigenous bacteria on the growth of E. oryzae fungus with the method of in-vitro test is from 58.8% to 62,2 %.
