<![CDATA[The aims of this research is to know the difference of sugarcane productivity, yield and crystalproductivity between sugar cane crops and ratoon unloading system and ratooncane system.The research was conducted on July 17, 2017 to July 31, 2017 at PT. Perkebunan Nusantara XISemboro Sugar Factory in Rejoagung Semboro, Jember, East Java. The research method usedin this research is descriptive analysis method. Data types use primary data and secondary data. Variable in this research consist of two independent variable that is sugar cane discharge system of ratoon and sugarcane crop of ratoon cane system. The parameters observed were:productivity of sugarcane (ton / ha) during last 4 years (2013 - 2016), Rendement (%) during last 4 years (2013-2016), crystal productivity (ton / ha) during last 4 years (2013 -2016). The data were analyzed by using T test two independent variables were T independent sample test. The results showed that the productivity of sugarcane with ratoon unloading system is highercompared with keprasan system. Or in other words, unloading ratoon can increase theproductivity of sugar cane significantly. The yield of sugar cane with ratoon unloading system ishigher compared with ratoon cane system. Or in other words, unloading ratoon can increase the rendement of sugar cane significantly. The productivity of sugar cane with ratoon unloadingsystem is higher than the keprasan system. Or in other words, unloading ratoon can increase the productivity of sugar cane significantly.]]>
