Abstract

The rain water harvesting system consists of a land area cultivated with rice and soybean cropping pattern annually, and a rainwater collection pond. Surpluswater (runoff) in raining season is captured and collected in the pond, and used for irrigation in the following cultivation. The objective of this researchwas to determine the optimumratio of the landto pond area. This researchwas carriedout in the IntegratedField Laboratory, Faculty of Agriculture, University of Lampung by using data of soil physical properties (water content, field capacity, permanentwilting point, percolation); rice crop coefficient, soybean crop coefficient and climatological data for 13 years from1999 to 2011. Datawas processed using asimulation program(Visual Simulation)presented inthe graphical form. The results showed that the rainwater potential that can be utilized as an alternative irrigation is abundant, about 1500 mm/year - 3000 mm/year with a total of rainwater reaching 314.509,78 m3 over 13 years. Based on the simulation, the most effective period of planting, for rice is in January and for soybean is in May. In addition, the optimum pond dimension to serve 1 ha cropping land is about 2450 m2 in with 3m depth, or the ratio of land to pond is 4:1.
