Abstract

This research discusses the factors that affect inflation in Solok Regency. The purpose of this study is to reduce the dimensions of inflation factors by using the Principal Component Analysis method so that the main components are formed. This study consists of 11 variables, namely the amount of onion production 〖(x〗_1), the amount of chili production 〖(x〗_2), the amount of banana production 〖(x〗_3), the amount of coffee production 〖(x〗_4), the amount of chicken egg production 〖(x〗_5), the amount of duck egg production 〖(x〗_6), the amount of beef production 〖(x〗_7), the amount of goat meat production 〖(x〗_8), the amount of chicken meat production 〖(x〗_9), the amount of duck meat production 〖(x〗_10) and the amount of pond fish production 〖(x〗_11). The results of this study show that of the 11 variables studied, it was reduced to 9 variables consisting of 2 main components. Principal component 1 has forming variables namely x_5,x_6,x_9,x_10,x_11 with a variance diversity of 44.221%. Principal component 2 has forming variables namely x_1,x_2,x_7,x_8 with a variance diversity of 34.892%. The two main components provide a cumulative diversity proportion of 79.113%.
