Abstract
Sugarcane plantations in Indonesia are mainly grown on dry land with wide ranges of climatic conditions. This study aimed to present information about the average rainy season period and climate classification in each sugarcane development area in Indonesia. The rainy season period was determined based on early of the dry season and rainy season for 10 years from 2009-2018 in 67 Zone of Season (ZOM) of 342 ZOM issued by The Agency for Meteorology, Climatology and Geophysics of Indonesia. The rainy season period in sugarcane regions ranges from 20-25 ten day period in 59% of the zones in Sumatra, 15-20 ten day period in 73% of the zones in Java and Madura, 20-25 ten day period and 10-15 ten day period in 33% and 34% zones in Sulawesi, 12 ten day period in West Nusa Tenggara and 16-25 ten day period in Papua. Climate classification was also identified in each zone of sugarcane regions based on Oldeman classification map. Information about rainy season period and climate classification enables in the planning and production of crops for certain regions. Further studies on the prediction of water availability during sugarcane growth are needed.
