DAMPAK SUBSIDI HARGA PUPUK TSP DAN UREA TERHADAP KONTRIBUSI PRODUKSI JAGUNG JAWA TIMUR PADA PRODUKSI JAGUNG NASIONAL
Abstract: Corn is one of the
strategic commodities, which has an economic value and a wide opportunity to
develop. Because of its role as primary carbohydrate and protein sources after
rice, and as a basic material for industry. Recent years, the need toward corn products
continually increases, which is in a line with the more increasing population
growth and corn consumption. East Java is one of the biggest corn belts in
Indonesia. For corn yields, there is a yield discrepancy between corn yield
rates produced by farmers and research Institute. One of the causes is the high
price of fertilizer. The government policy that is to subsidize the fertilizer
price will help corn products produced by the farmers. The goals of this study
are to know the development of corn product contribution in East Java toward
national corn products, to explore the influence of subsidized prices of TSP
and Urea fertilizers to corn products in East Java and to find out the impacts
of government policy, to subsidize the fertilizer prices, toward corn product
contribution in East Java. This research uses secondary data taken from the
year 1985-2006 by using two-stage least square method (2SLS) and trend method.
The results of this study indicate that: (1) the development of corn product
contribution in East Java toward national corn products tends to decrease; (2)
the subsidized price of TSP fertilizer gives a negative influence to corn
products while the subsidized price of Urea fertilizer gives a positive
influence to corn products; (3) the impact of subsidized price of TSP
fertilizer can decline the corn product contribution in East Java while the
impact of subsidizes price of Urea fertilizer can increase corn product
contribution in East Java.
