An Application of Moderate Resolution Imaging
Spektroradiometer to Optimize Water Allocation in
1Agriculture Technology, Papua University, Indonesia.
Restrictiveness of climate data have been most problems in crop water requirement
analysis as basic of water allocation in irrigation area that caused by limited number of
weather stations. Remote sensing is an advance technology that able to estimate crop
water requirement. The remote sensing data must have visible electromagnetic spectrum (0.4 μm – 0.7 m), near-infrared (0.7 μm – 1.3 m), short wave infrared (1.3 μm – 3.0 m), and thermal infrared (8.0 μm – 14.0 m). Moderate Resolution Imaging Spektroradiometer (MODIS) is one of satellite remote sensing data that equipped with those electromagnetic spectrum. These research was conduct in Situbondo Irrigation System – Situbondo – East Java with 3 phase, that is data inventory, data processing, and evaluation. The materials that used in this research are Moderate Resolution Imaging Spektroradiometer (MODIS), Digital Elevation Model (DEM), evaporations data, and wind speed. The accuracy of Moderate Resolution Imaging Spektroradiometer to analyze crop water requirement in Situbondo Irrigation System is 83% compared with Pan Evaporation method.
Keywords: Crop Water Requirement, MODIS, Remote Sensing, Water Allocation.
