This study aimed to 1) analyze the elasticity of rice consumption demand
in
Purbalingga Regency, 2) analyze the trend of rice consumption in Purbalingga
Regency, and 3) examine the factors affecting rice consumption in Purbalingga
Regency.
Data collection was conducted from March 2023 to January 2024 using a
quantitative descriptive research method with a secondary data analysis
approach. Secondary data analysis was obtained from the Central Statistics
Agency (BPS) of Purbalingga Regency website and archival documentation from
relevant institutions. The analysis employed multiple linear regression analysis
through natural logarithms with the equation Y = 0.838 + 0.035X1 + 0.049X2 +
1.195X3.
The results of the elasticity analysis of the static model indicated that
the
price of rice was perfectly inelastic (0=0), rice production was perfectly inelastic
(0=0), and the population was perfectly elastic (1=1). The trend of
rice
consumption in Purbalingga Regency increased from 2000 to 2022 by 22.09%,
reaching an average rice consumption of 102,502,123 kg/capita/year. However,
the forecast for 2023 revealed a decrease to 114,470,869 kg. The multiple linear
regression analysis resulted in an F value of 21.317, exceeding the F table value
of 3.10. Therefore, the null hypothesis (Ho) was rejected, and the alternative
hypothesis (H1) was accepted, indicating that the variables of rice price,
rice
production, and population simultaneously contribute a significant effect on
rice
consumption in Purbalingga Regency
