Sampling of Square Segments by Points for Rice Production Estimate and Forecast

Abstract

Rice is the staple food of most Indonesian peoples. This commodity plays an important role in the economy of Indonesia. Because of this the government of Indonesia should be careful in drawing a certain policy, especially the policy which is related to the context of rice crop development planning. To support this rice crop development planning, an accurate data i.e. a rice production estimate is needed. Statistical services on agriculture are based on different approaches, resulting from both historical reason and available techniques, to provide reliable figures. Most often, the applied systems are based on: village statistics, census, sampling survey based on list frame or area frame, and administrative by products. The Area Frame Sampling is one of the methodologies to obtain the rice crop area estimation as agricultural statistic data. In this method/system, crop area estimates are generated through area frame sampling data. All the components are integrated into the system to support timely generation of reliable information on the crop area of the major commodity in the study area. In the present paper, we mainly try to review the approach of area frame sampling for rice estimate that has been developed in Indonesia for several years. The discussion would be focused on area frame construction, field survey, data communication and some results.
