Iodized salt is universal effort to eliminate iodine deficiency disorders (IDD). Iodine consentration in iodized salt needs to be evaluated due to many cases of hypothyroid and hyperthyroidism. Objective. The purpose of this study was to describe whether iodized salt consumed by peoples contributes to hypothyroidism and hyperthyroidism cases. Method. This was a descriptive study in area with the highest cases of hypothyroidism and hyperthyroidism based on data from Klinik Litbang GAKI Magelang 2005-2012. Samples were taken using purposive sampling with a sample size of 90 households per area. Area with the highest case of hyperthyroidism is Mertoyudan Sub District while area with the highest case of hypothyroidism is Salaman Sub Districts, both in Magelang District. Iodine content in salt was by taking sample of salt from households which used for daily consumption. Statistic analysed used were independent sample t test and Chi Square. Result. The results showed that salt consumed in both areas already contains iodine. Salt iodine content level in area with the highest hyperthyroidism (55.1±23.84 ppm) was higher than in the area with the highest hypothyroidism (49.79±39.28 ppm). According to the category of iodine content in salt, iodine content below standards (<30 ppm) is higher in area with the highest hypohyroidism (25.6 percent). Iodine content above standars (>80 ppm) is higher in area with the highest hyperthyroidism (13.2 percent). However iodine content in both areas showed no significant difference (p=0.27). Conclusion. Iodized salt consumption does not contribute to the high case of hypothyroidism or hyperthyroidism. Salt consumed in area with the highest cases of hypothyroidism and hyperthyroidism already contains iodine as standard. It is possible that there are other factors that cause high incidence of hypothyroidism and hyperthyroidism in those areas that needs further research. Keywords: hyperthyroidism, hypothyroidism, iodine, salt ABSTRAK Latar Belakang. Iodisasi garam merupakan upaya universal untuk menanggulangi Gangguan Akibat Kekurangan Iodium (GAKI). Perlu dilakukan evaluasi kandungan iodium dalam garam beriodium karena masih ditemukannya kasus hipotiroid dan hipertiroid. Tujuan. Tujuan penelitian ini adalah untuk menunjukkan apakah garam beriodium yang dikonsumsi masyarakat berkontribusi terhadap kejadian hipotiroid dan hipertiroid. Metode. Desain penelitian adalah deskriptif kuantitatif. Penelitian dilakukan di daerah dengan kejadian hipotiroid dan hipertiroid tertinggi berdasarkan data Klinik Litbang GAKI Magelang tahun 2005-2012. Sampel diambil dengan teknik purposive dengan perhitungan besar sampel didapatkan sebanyak 90 rumah tangga per daerah. Daerah dengan kasus terbanyak hipertiroid adalah Kecamatan Mertoyudan, Kabupaten Magelang sedangkan kecamatan dengan kasus terbanyak 35
