Penelitian ini bertujuan (1) mengetahui perkembangan produksi ubi kayu (2) mengetahui respons produksi ubi kayu melalui pendekatan respons luas panen dan respon produktivitas (3) mengetahui elastisitas produksi ubi kayu dalam jangka pendek maupun jangka panjang. Penelitian ini menggunakan data sekunder dengan time series mulai tahun 1982-2011, yang diperoleh dari Badan Pusat Statistik. Analisis respons penawaran ubi kayu dilakukan dengan menggunakan model penyesuaian parsial Nerlove dengan metode estimasi Ordinary Least Square pada E-views 4. Hasil penelitian menunjukan bahwa (1) perkembangan produksi ubi kayu meningkat (2) respons luas panen dipengaruhi harga riil ubi kayu, harga riil ubi kayu tahun lalu, harga riil ubi jalar, luas panen tahun lalu dan respons produktivitas dipengaruhi oleh harga riil ubi kayu, harga riil pupuk urea, harga riil pupuk TSP, curah hujan dan produktivitas tahun lalu (3) Penawaran responsif terhadap harga, dengan elastisitas yang bersifat inelastis dalam jangka pendek maupun jangka panjang.

This research aims at (1) knowing the development of the production of cassava (2) knowing the production response of cassava through extensive response approach productivity response (3) knowing the elasticity of cassava production in the short and long term. This study uses secondary data with time series starts in 1982-2011, which was obtained from the Central Bureau of Statistics. Analysis of cassava supply response has been done by using a partial adjustment Nerlove’s model with estimation methods of Ordinary Least Square on E-views 4. The research results showed that (1) the cassava production increased (2) harvested area response was affected by cassava real price, cassava real price last year, sweet potatoes real price, harvested area last year, and the response of productivity has been affected by cassava real price, fertilizers- urea and TSP- real price, precipitation and the productivity last year (3) the offer was responsive to the bidding price, with an elasticity in short term and long term.
