Supply Response Analysis of East Java. Team Supervisor.
East Java Province is one of the
centers of soybean in Indonesia. Soybean is an important commodity, therefore,
efforts toward self-sufficiency is a program that should disukseskan. Efforts
to increase production and productivity levels of soy needs to be addressed
through trending policies, including policies of intensification,
extensification, rehabilitation and improvement of production.
The purpose of this
study was to estimate the supply response of soybean in East Java. Specifically
this study uses data over the period 1970-2010, the estimated elasticity of
suspect soybean harvested area, productivity and supply of soybean by using
Model Nerlovian. The research was supported by the data available from the
agency the Central Bureau and the Department of Agriculture Stastistik East
Java Province, as well as related institutions and agencies, thus providing an
opportunity to measure the supply response of soybean farmers in East Java as a
reaction to changes in soybean prices.
The analysis showed that the
soybean crop acreage elasticity to price is equal to 0.112 in the short run and
by 0.163 in the long run, in this case the input is obtained to conduct
extensive in supporting efforts to increase soybean production through the
area. The results of productivity analysis indicate that soybean productivity
on the price elasticity is equal to 0.015 in the short run and by 0.039 in the
long shelf, in this case the obtained input for intensification in supporting
efforts to increase soybean productivity through improved technology. The results
showed that soybean
supply elasticity of East Java 0.127 in the short term and long-term elasticity
of 0.202, indicating that the soybean farmers' response to price changes. The
value of this elasticity in the range of inelastic, meaning that the percentage
changes in supply less than the price which decreased by 0.127% in the short
term and 0.202% in the long run due to a decrease of 1% soybean prices.
