Kajian Hubungan Antara Curah Hujan dan Produktivitas Tanaman Nanas (Ananas comosus L.) Di Kabupaten Blitar.

Pineapple is a horticultural commodity whose demand is still relatively high because of its need as fresh fruit and processed raw materials. The East Java region contributed 8.92% with Blitar Regency being the second largest pineapple production center after Kediri Regency. Pineapple plants are plants that are sensitive to climate change due to the effects of excessive heat and irregular rain. This can threaten pineapple productivity by reducing yield potential and quality which will derail the harvest. This study aims to study the relationship between elements of rainfall (rainfall intensity and rainy days) and productivity of pineapple plants in Blitar Regency. The research was conducted from June to September 2020 in the pineapple production centers of Blitar Regency, namely Gandusari District, Ponggok District and Nglegok District. The research method used is a survey method with the data used in this research in the form of primary data and secondary data. Primary data obtained from interviews with farmers. The secondary data needed is pineapple productivity in Blitar Regency from the Central Statistics Agency and rainfall data (rainfall intensity and rainy days) from the Central Statistics Agency and Meteorology, Climatology and Geophysics Agency. Correlation analysis was used to determine the close relationship between rainfall and productivity and regression to determine which rainfall element had the most influence on productivity. Based on the results of the analysis, it is explained that the rainfall element has a significant effect on pineapple productivity and can reduce productivity in the three sub-districts in Blitar Regency.
