Abstract

This study examines the impact of tobacco production and cultivated tobacco area on the Gross Regional Domestic Product (GRDP) of the agricultural sector in Lampung Province from 2016 to 2022. Utilizing the multiple linear regression analysis method, this research analyzes the relationship between tobacco production (X₁) and tobacco cultivation area (X₂) as independent variables, with GRDP of the agricultural sector (Y) as the dependent variable.  The analysis results indicate that both independent variables exhibit a negative relationship with the agricultural sector’s GRDP, with regression coefficients of -2688 for tobacco production and -3309 for tobacco area. The classical assumption tests confirm the model’s validity by meeting all statistical assumptions. These findings suggest that an increase in tobacco production and cultivated area may actually lead to a decline in the agricultural sector’s GRDP, potentially due to the reallocation of resources from more productive agricultural sub-sectors.
