Abstract
Indonesia as a humid country has two climate seasons:  dry and wet seasons. Decreased dry land agriculture productivity is due to a limited availability of water especially in dry season; while during the wet season, water from rainfall as a runoff couldn’t conserve on the soil maximally. The potential runoff can, certainly, be utilized as an alternative water source in dry season. The main purpose of the present research is to manage runoff using technological means during the wet season for the dry seasons agriculture production. The research was conducted on dry land agriculture at Jatinangor Research Station, West Java, Indonesia. The research methods are survey, descriptive analysis and observations on potential runoff and prediction by using Rational Method, location mapping, rainfall analysis and crop water requirement analysis. The prediction analysis indicated that peak of runoff occurred in January was about 200.46 m3. This result is in line with the peak of rainfall occurred in the research station field (297.94 mm). The annual total potential cumulative runoff was 1160.05 m3; which indicates that runoff potential is an alternative source for irrigation water in the dry land. Analysis of the ratio of the catchment area to the area of cultivation shows that C: CA is 14.8. This means that in order to produce a monoculture of corn of 1000 m2 for 3 seasons in one year, it requires a 14.800 m2 of catchment area.
