THE EFFECT OF LAND AREA, YIELD, AND MILLING CAPACITY ON SUGAR PRODUCTION IN PT PERKEBUNAN NUSANTARA (PTPN) XI
Abstract
This research has been carried out at PT. Perkebunan Nusantara XI aims to evaluate the influence of some factors, such as land area, yield, and milling capacity, on sugar production at PT. Perkebunan Nusantara XI. This study uses secondary data in the form of quantitative data from production records belonging to PTPN XI from 2011 to 2020. The data obtained were then analyzed statistically using multiple linear regression. The simultaneous effect of the three variables on sugar production has been analyzed using the F test. In contrast, the partial effect of each variable has been analyzed using the t-test. The statistical analysis results showed that the three variables, land area, yield, and milling capacity, had a positive and significant simultaneous effect (P <0.05) on sugar production. The results of the partial analysis showed that land area had a positive and significant effect (P<0.05) on sugar production, but yield and milling capacity had no significant effect (P>0.05) on sugar production. Based on the results of multiple linear regression analysis showed that land area and yield had a significant effect (P<0.05) on sugar production. In contrast, milling capacity had no significant effect (P>0.05) on sugar production. The equation of the multiple linear regression lines between land area, yield and milling capacity on sugar production is as follows: = -59.038 + 3.860 X1 + 3.860 X2 - 0.799 X3 + 0.05. The conclusion is that land area, yield, and milling capacity simultaneously affect sugar production, while yield, and milling capacity partially does not affect sugar production.
