Abstract

Food is one of the basic human needs. A priority food commodity is rice. The Special Region of Yogyakarta Province is one of the areas that has agricultural land that is able to supply the food needs in the area. However, the population in the Special Region of Yogyakarta is growing annually, having an impact on the food needs that have to be met. The study aimed to determine the food reserves, especially rice reserves, in the Special Region of Yogyakarta. This study used a descriptive analytical method and ARIMA forecasting model. The study used time series data from 2011 to 2021 obtained from the dataku application managed by BAPPEDA of the Special Region of Yogyakarta. The data consisted of rice production data, per capita consumption data, and population data. The results showed that the rice reserves in the Special Region of Yogyakarta from 2011 to 2021 decreased over years. Based on the forecasting results, the best model was ARIMA c(9,1,6). In addition, the result of the rice reserve forecast from 2022 to 2025 also showed a decreasing trend from year to year. Therefore, it is crucial for the government to make efforts to maintain food availability to achieve local food security.Keywords: ARIMA, Food Reserves Rice, Forecasting, Special Region of Yogyakarta

Cassava is a commodity that has the potential to be developed into a regional superior product. Cassava can be processed into other forms of food that are consumed by the community and one of the centers is in Magelang Regency. This study aims to analyze what factors influence the supply of cassava in Magelang Regency. The data used comes from secondary data. The data used from 2008 to 2022 comes from the Central Bureau of Statistics. The results of the study stated that the supply of cassava in Magelang Regency was jointly influenced by the previous year's cassava price, the previous year's sweet potato price, the previous year's cassava production, the harvested area of ​​the previous year's cassava, the previous year's corn price. Meanwhile, partially the supply of cassava in Magelang Regency was influenced by the price of sweet potatoes in the previous year and the cassava harvested area in the previous year. Based on the results of the analysis, the price elasticity of cassava in the previous year on cassava supply in Magelang Regency was inelastic for both short-term elasticity (0.701) and long-term elasticity (0.02).
