Evaluation of Paddy Production Mesurement in Indonesia

Abstract

For many years, paddy production data was obtained from 2 different sources namely harvested area (form monthly report of agricultural statistics; Statistik Pertanian (SP)) and productivity from Ubinan Survey. Both sources need a standard operational procedure (SOP) and an officer to do it. Based on the data, the government states that the paddy production is self-sufficient. However, in fact, the government is still importing the rice. The fact the government still importing the rice is become concerns from researcher. We would like to investigate this issue by doing an in-depth interview involving respective parties. With this method, researcher tries to retrieve an information related to potential sources of bias and measures bias in every step of SP and Ubinan Survey. This bias are allegedly influenced by the implementation of data collection is not in accordance with the SOPs that has been determined. As a result of indepth interview, potential sources of bias in SP are influenced by 50% officers when they are doing the data collection with compilation. The other influence is that 22%-50% officers are not doing verification into the field after acquiring the harvested area data. Meanwhile, the potential sources of bias in Ubinan Survey indicating that the occurance of officers whose 5% - 10% doing listing and enumeration not timely and 5% doing replacement of selected paddy farmer/respondent. Both source of potential bias (SP and Ubinan Survey) makes a bias for harvested area of paddy between 12.61% - 20.72% and bias for paddy productivity between 0.23% - 0.25%.
