Abstract

Sugar is one of the strategic commodities in the Indonesian economy. The main raw material for making sugar in Indonesia comes from the sugar cane plant. Sugarcane is a seasonal plantation commodity crop, wherein one year there is only one harvest. Sugarcane productivity is largely determined by agro-climate, in addition to the cultivation technique factor. Apart from climatic factors, the area of milled sugarcane is strongly influenced by the price of sugar at the farmer level, especially 1-2 years before production. This study aims to determine the factors that affect the productivity of the sugarcane in Jember Regency which is poured into a mathematical model. The factors that are thought to affect sugar production in Jember Regency are rainfall (X1), number of rainy days(X2), planting area(X3), sugarcane production(X4), humidity (X5), and temperature(X6) from 1990-2020. The method used in solving this problem is a linear regression with detailed analysis to form an optimum mathematical model. The mathematical model obtained is Y=-5,192X_1^1,16 X_2^0,242 X_3^0,141 X_4^0,132 X_5^14,1 X_6^31,9. The results of the analysis are expected to be used as recommendations by the government to determine policies in increasing the productivity of sugarcane in Jember Regency.
