From the problems, there were made research hypotheses, namely: (1) It supposed that RISA soybean milk business in each year experienced profit increase.

This case showed that the first research hypothesis proven, that the home industry business of RISA Soybean Milk of Malang experienced profit in each year. The time series forecasting analysis was used to know the RISA soybean milk selling in 2011. From the calculation results, obtained the sale forecasting result for 2011 as much as 25,172 liters/year. The amount increased from the sale results in 2009 which as much as 17,727 liters/day.
