REGIONAL DEVELOPMENT: THROUGH A STRUCTURAL MODEL APPROACH ON THE EFFECT OF INTERNAL CONDITIONS ON INTEGRATED AGRICULTURAL SYSTEMS OF RICE FIELD-BUFFALO LIVESTOCK IN HUMBANG HASUNDUTAN DISTRICT

This study aims to examine regional planning: through a structural model approach on the effect of internal conditions on integrated agricultural systems of rice fieldbuffalo livestock in Humbang Hasundutan District, by analysis method of structural equotation modeling (SEM) with IBM SPSS® Amos 22 device.
