PENGARUH PENGUJI TERHADAP ESTIMASI KADAR IODIUM DALAM GARAM MENGGUNAKAN TEST KIT

Elimination of Iodine Deficiency Disorders (IDD) is expected to be achieved through Universal Salt lodization (USI) where at least 90 percent of households consume iodised salt that contained sufficient iodine i.e. 30 ppm of potassium iodate. At national level, simple semi quantitative test kit is used to estimate and monitor of iodine content in salt at household level. However, result of estimation of iodine content in salt maybe influenced by the obsener. This paper present the influenced of observers in the estimation of iodine content in salt using semi quantitative tes kit. Methods. Forty five house wives and forty five cadres in Bantul District, Yogyakarta were selected purposively as observer. Every test observer was asked to bring salt sample (3 tables spoon). The observation was conducted twice where the second observation was done 2 weeks after the first observation. The semi quantitative test kit used in this study was test kit that developed by BP2GAKI, Magelang. The analysis chi square and F-test was done to examine the influenced of test observer on the result of iodine content compared to the iodometric titration as a reference method. Results. The results showed that observation test from 60,46% of house wives and 71,10% cadres at the first obsenation was similar to with the reference method. However, at the second observation test, only 52,38%, of house wives and 56,82% of cadres was similar to with the reference method (p>0.05). Result from group of34-44 years of age had the highest coincidence with reference method. Moreover, result from housewives and cadres with high school educational had the highest similar to reference method. Conclusions. There was no significant difference (p>0.05) in the estimation of iodine content between ordinary housewives and cadres. Age and educational level of the observer was not statistically influence the result of iodine content estimation using semi quantitative iodine test kit.
