Abstract

El Nino events cause a reduction in rainfall in most parts of Indonesia. The precipitation reduction varies depending on the intensity of El Nino and geographic location areas concerned. Reduction of rainfall in Indonesia could potentially disrupt the operational of irrigation in some areas in Indonesia. As a result of El Nino events, there has been a decrease in the average food production in Indonesia during the years 1968 to 2000. This study aims to analyze the influence of El Nino on rainfall characteristics in Sekampung Irrigation Area and Rawa Sragi Irrigation Area in Lampung Province. Sekampung Irrigation Area and Rawa Sragi Irrigation Area are inland irrigation area and swamp irrigation area, respectively. Rainfall data from Pringsewu Rainfall Station (for Sekampung Irrigation Area) and Palas Rainfall Station (for Rawa Sragi Irrigation Area) have been used to investigate the impact of El Nino on the potential reduction in the irrigation water availability in both irrigation areas. The results show that due to the influence of El Nino, there has been decline on rainfall in the dry season in the area observed. The month of August, September, and October are the most sensitive months to the effects of El Nino. The results also showed that there is no fact indicates whether inland irrigation areas are more sensitive to El Nino impact rather than swamp irrigation areas and vice versain Lampung Province. Based on the classification of climate patterns in Indonesia, the whole area in Lampung province is included in areas where rainfall is strongly influenced by the monsoon circulation. Based on this fact, we can conclude that there is no different impact of El Nino on Way Sekampung and Rawa Sragi irrigation area.
