Dengan potensi ekonomi yang besar dari ubi kayu dalam perdagangan dunia dan meningkatnya kebutuhan dunia akan ubi kayu serta dengan keterbatasan-keterbatasan Indonesia dalam meningkatkan produksi ubi kayu, perlu dikaji faktor-faktor yang dapat mempengaruhi produksi, konsumsi maupun harga ubi kayu di Indonesia. Produksi ubi kayu dipengaruhi secara signifikan oleh variabel harga ubi kayu, luas areal panen ubi kayu dan harga pupuk urea. Konsumsi ubi kayu di Indonesia dipengaruhi secara signifikan oleh variabel jumlah penduduk Indonesia. Harga ubi kayu di Indonesia dipengaruhi secara signifikan oleh variabel luas panen ubi kayu, konsumsi ubi kayu dan panjang jalan beraspal. Berdasarkan proyeksi, produksi ubi kayu akan mengalami peningkatan jika harga ubi kayu, produktivitas lahan ubi kayu maupun luas panennya ditingkatkan. Konsumsi ubi kayu Indonesia diproyeksikan akan mengalami penurunan jika secara bersamaan ada peningkatan harga ubi kayu, peningkatan pendapatan perkapita dan adanya peningkatan jumlah penduduk Indonesia. Harga ubi kayu diproyeksikan akan mengalami peningkatan jika konsumsi ubi kayu mengalami penurunan dibarengi dengan penurunan luas areal panen ubi kayu.

With great economic potential of cassava in the world trade and the increasing world demand for cassava as well as the limitations of Indonesia to increase cassava production it needs to be investigated factors that can affect the production, consumption and prices of cassava in Indonesia. Cassava production is significantly influenced by the variable price of cassava, cassava harvested area and price of urea fertilizer. Consumption of cassava in Indonesia is significantly influenced by population of Indonesia. The price of cassava in Indonesia is significantly influenced by cassava harvested area, consumption of cassava and the length of tarred road.

Based on projections, cassava production would increase if cassava price, cassava land productivity and harvested area are improved. Indonesian cassava consumption is projected to decline if there are increasing in cassava price, per capita income and population of Indonesia simultaneously. The price of cassava is projected to increase if the consumption of cassava decreased accompanied by a decrease in the total area harvested cassava.
