ANALISIS PENAWARAN BERAS DI KABUPATEN KLATEN

Abstract

Abstract: This research aims to identify and to analyze the variables which influenced the rice supply in Klaten District and to know its elasticity. This research used descriptive analysis. The research location was chosen purposively in Klaten District, by using 16 years time series data and the data analysis used is multiple linear regression on supply function Nerlove models. The result of analysis shows that R² 0,926 which means that 92,6 % of rice supply in Klaten District can be explained by rice production amount at the past time, wide areal planting in the year of cultivation, rice price variable at the past time, corn price at the past time, urea fertilizer price in the year of cultivation, rainfall average in the year of cultivation, while the rest of it, about 7,4 % is explained by other variable outside the variable which is investigated. Based on F examination in the level of validity 95% is bigger than F table, which is 18,687>3,37. The short term and the long term elasticity value of wide areal planting in the year of cultivation are 1,740 and 2,413 is elastic. The short term elasticity value of rice price at the past time to 0,818 is elastic and for long term elasticity to 1,134 is elastic. The short term  and the long term elasticity value of corn price at the past time to -1,352 and -1,875 is elastic. The short term elasticity value of rainfall average in the year of cultivation to -0,890 is inelastic and for long term elasticity to -1,234 is elastic.
