Abstract

The evaluation of water availability is crucial in planning and managing irrigation system. Rainfall is a climatic element having a very important role to provide crop water requirement. However, the amount of rainfall also depends on other climatic factors such as air temperature, humidity, wind speed, and solar radiation. Based on this problem, this study aimed at analysing the temporal pattern of climate factors at the research location and evaluating water availability for irrigation through calculating the reference evapotranspiration (ETo). The descriptive quantitative analysis approach was used. The research carried out by collecting the data through field survey taking primary and secondary data. Data tabulation from Cropwat version 8.0 software was used to analyse water availability from climatic data. The results showed that the reference evapotranspiration (ETo) ranged from 4.28 mm/day to 5.73 mm/day. The peak of ETo is in January to May. The maximum ETo value is in April, while the minimum ETo value is in September. The highest average maximum temperature occurs in November, which is 27.8 ℃. The highest average minimum temperature occurred in April at 26.1 ℃. The highest solar radiation duration is in November of 12.5 h. The highest wind speed is in November, which is 71 km/day. The highest relative humidity of 88% occurs in January and February. The high monthly rainfall in January is 287.0 mm/month with an effective rainfall of 197.9 mm/month.
