【 摘 要 】

Sugarcane is one of the important plantation crops commodities in plantation sub-sector development in East Java. However, domestic sugar needs are increasing every year, even making the government decide on the policy to import sugar. This situation shows that sugar is a basic requirement in Indonesia. The profitability of sugar agro-industry is influenced by climate and price. Low price and production risks affect the company's sustainable resilience. Rainfall is an important climate element and determines the plant water balance. While the incidence of climate anomalies in Indonesia has been shown to predominantly affect agricultural production and food security, besides that the fertilization process is also a major factor influencing the production of sugar cane produced. Fertilizer can provide nutrients in the soil, so that sugar cane can grow well. Sugar production in Asembagus factory every year has fluctuations, some of the dominant factors are the influence of rainfall and fertilization. The results showed that rainfall(X 1) and fertilization(X 2) significantly affected sugarcane productivity(Y). The regression model is Y = 33633 + 9,43X 1 - 2,10X 2. The modeling results are expected to be used as a company recommendation to determine policies in increasing Asembagus sugar factory production and more productive sugarcane cultivation techniques.
