National economic growth is an aggregate of regional economic growth. Economic growth in both national and local level is closely related to the performance of the productions of goods and services, which measured by massive increase in the amount of the Gross Domestic Product (GDP) and Regional Gross Domestic Product (RGDP) for the region. Lampung province's economic growth performance is high enough but on the other hand had to be paid by land conversion. This study aims to determine changes in forest cover and land as well as its influence on the RGDP in agriculture, forestry and industry. Data collected consist of satelitte image of lampung province RGDP in agricultural sector, RGDP in foresty sector, RGDP in industrial sector and population density data. The research method is to perform modeling of multiple linear regression Ummi Dienelly using Minitab version 16, with the response variable Y 1 is the RGDP in the agricultural sector, Y 2 is RGDP in the forestry sector, Y 3 is RGDP in the industrial sector and the explanatory variables (X) used include the proportion of forest area of the country , privat forests, agricultural land, rice fields, and undeveloped land, plantations, other areas, and the data density of population per km 2. The result showed that there was a significant relationship beetwen changes in private forest cover by 11.055 (p= 0.062), rice field by 7.982 (p= 0.082), and population density by-8.676 (p= 0.000) to the RGDP in agricultural sector. RGDP in the forestry sector is affected significantly by the national forest cover by 1.160 (p= 0.00) and other land use by-0.803 (p= 0.061). RGDP in the industrial sector is influenced significantly by private forest-7.434 (p= 0.077), and plantation by 5.471 (p= 0.00).
