ABSTRAK
Pergerakkan harga domestik dipengaruhi oleh beberapa faktor, seperti harga internasional barang tersebut, harga minyak dunia, nilai tukar, hingga kebijakan pemerintah. Intervensi pemerintah melalui kebijakan dapat dilakukan melalui mengontrol harga, pengaturan ketersediaan stok barang tersebut di masyarakat, dll. Pengujian ekonometrik melalui error correction model digunakan untuk mengetahui seberapa besar penyesuaian harga domestik ketika terjadi kenaikan maupun penurunan harga internasional pada komoditas barang kebutuhan pokok. Hasilnya menunjukkan bahwa terjadi penyesuaian harga domestik ketika terjadi kenaikan maupun penurunan harga internasional pada komoditas tepung terigu, gula pasir, kedelai, daging sapi, dan daging ayam broiler. Penyesuaian harga domestik tidak terjadi pada komoditas beras dan telur ayam ras berdasarkan koefisien dan level signifikansinya.

ABSTRACT
Domestic price movements are affected by several factors, such as the international price of the goods, world oil prices, exchange rates, and government intervention. Government can do several actions in order to make domestic price of the goods reachable to domestic consumers, such as controlling prices, regulating the procurement of the goods, etc. Econometric testing through error correction model is used to find out how much the adjustment of domestic price when the increase and decrease happened to international price on commodities of staple foods. The results indicate that the adjusments happened in domestic price on the commodities of flour, sugar, soybean, beef, and broiler chicken. Domestic price adjustments do not occur in the commodities of rice and chicken egg based on its coefficient and level of significance.
