Abstract

Potato is one of the subtropical horticultural crops that are widely cultivated in the highlands in Indonesia. Pengalengan and South Minahasa are two regions in Indonesia that are famous for their potato production. This study aimed to compare the effect of climate condition on potato productivity in Indonesia. This study used inferential statistical methods with two variables, they were the dependent variable and independent variable. The dependent variable used was potato productivity data in Pengalengan and South Minahasa, while the independent variable used were temperatures and rainfalls. The data in this study was analyzed using correlation analysis. Based on the results of the correlation analysis, it was known that temperatures had had a negative correlation on potato productivity in Pengalengan and South Minahasa. Later, it was discovered that rainfalls had negative correlation on potato productivity in Pengalengan and South Minahasa. However, neither temperatures nor rainfalls, had a significant effect on national potato productivity in Indonesia. This could be caused by the use of varieties that have high productivity and have low sensitivity to temperature and rainfall fluctuation.
