The variable is the most dominant effect on net income in the agribusiness firm LQ 45 index listed in the Indonesia Stock Exchange in 2007 until the year 2010?. The purpose of this study was conducted to analyze and to determine the effect of variable fixed assets, long-term debt and equity to net income in the agribusiness firm LQ 45 index listed in the Indonesia Stock Exchange in 2007 until 2010.

Partially only 2 independent variables Xi which significantly affect the dependent variable Y1 fixed assets (X1) and capital (X3), and other independent variables Xi (loans) have not significant (p> 0.05) to the dependent variable Y1 free.
