Abstract
Increasing climate and extreme weather events such as ENSO and La Nina can affect water availability which has an impact on life, health, and food stability, one of which is the aquaculture sector where pond fishery is a source of animal food. This study aims to examine the sea level elevation that occurs during El Nino and La Nina conditions and its impact on the aquaculture sector in the Java Sea (Case Study: Central Java and the Sunda Strait). The observed effect of ENSO is the average sea level anomaly and average sea surface temperature during El Nino and La Nina conditions from 2007 to 2010.
The results of the analysis show that the El Nino and La Nina phenomena in certain waters affect the average value of sea level anomaly (SLA). When La Nina occurs, there is an increase in SLA, although not too significant, and when El Nino occurs, the average value of the sea level anomaly decreases. These two phenomena also show an influence on El Nino and La Nina. had an effect on increasing pond yields while La Nina had an effect on decreasing pond yields.
