Climatic and weather conditions, especially rainfall, play a role in affecting rice production. The rainfall that occurred in Serdang Bedagai Regency shows that the rainfall continued to increase, especially in the middle of 2015 which caused several agricultural areas to be disturbed and even damaged / fuso.
