Hubungan Berbagai Faktor Lingkungan dan Umur terhadap Biomassa Eucalyptus Urograndis

Abstract

Environmental factors is one of the factors that affect tree biomass increment that can not be modified . Therefore, a research had been conducted on Eucalyptus urograndis in Estate A , Sector Aek Nauli , PT Toba Pulp Lestari Tbk . To see the relationship between the dependent variable, is the biomass of E. urograndis and independent variable, is the rainfall , elevation , slope , soil pH , soil type and age of the plant , it is done by multiple linear regression analysis . The results showed that a significant effect on the biomass increase was Eucalyptus urograndis rainfall , elevation and age of the plant , while soil pH , slope and soil type had no significant effect . Value of the correlation coefficient is 0.88 which indicates that there is a very strong relationship and a direct relationship between the dependent variable and independent variables .
