Abstract
The alteration rain fall in Indonesia as an impact of climate variability and climate change has given huge impact to agriculture sector, not only on food crops, but also on horticulture crops. El Nino-southern Oscillation (ENSO) is an inter annual factor that influenced rainfall variability in Indonesia. The ENSO occurrences increase in its intensity and frequency. This paper aimed to identify the influenced of ENSO on rambutan (Nephelium Lappaceum L.) production in Indonesia. Rambutan is one of the most important tropical fruits in Indonesia. The data analyzed are time series production data all provinces and ENSO phase data. The data was analyzed by main island base (sumatera, Java, Bali and Nusa Tenggara, Kalimantan, Sulawesi, Papua and Maluku). The analysis reveal that annual production rambutan decreased on El-Nina years. Analysis by island also showed that productions decreased in all islands. The influenced El-Nina on production in Sumatera islands is less significant than other islands. Several research have reported that there is another factor that influenced Sumatera rainfall significantly, namely Indian Oscillation Dipole (IOD). ENSO have influenced the production of rambutan in Indonesia. Therefore efforts to understand the relation of ENSO and production should be assessed continuously.
