Forecasting of paddy harvest area should be done in order to produce information of harvest area before the harvest occurred. The potentials of harvest area paddy each district can be known quickly based on that prediction. Prediction of paddy harvest area can be obtained by using Landsat TM data based on estimation model of paddy’s age plant. The model use vegetation index (VI) parameter, which have high correlation with plant during its growth. The Sigmoid equation model can be used for estimating paddy’s ages from 1 until 12 week with form : IVt=l60/(l+l.549*exp(-0.l 1028*U). The Quadratic equation model can be used for estimating paddy’s ages from 1 until 12 week with form : IV = 1.1604 + 0,07827*U - 0,00134*U2. That models are model development from model before which was produced by I M. Parsa,et al, 1977. Based on analysis result onto Landsat TM data on December 1997 and January 1998 indicate that most harvest area at Java island in period I will be occured at Pebruary. The harvest area paddy at West Java (including Jakarta) is 577,692 Ha, at Middle Java is 657,540 Ha, at Yogyakarta is 49,343 Ha, and 636,536 Ha at east Java. The information is useful as input material for Agricultural Department, BULOG, and BPS for planning strategic of main food stock (rice).
