Besaran yang dapat digunakan untuk mendeteksi adanya multikolinearitas adalah faktor inflasi ragam (Variance Inflation Factor / VIF). Tujuan dari penelitian ini yakni untuk mengetahui cara mengatasi multikolinearitas, menentukan model persamaan regresi komponen utama, dan mengetahui variabel-variabel yang mempengaruhi impor beras di SULUT. Penelitian menggunakan data impor beras di Sulawesi Utara pada tahun 2006-2015. Data akan di analisis menggunakan analisis regresi komponen utama. Analisis regresi komponen utama dapat mengatasi masalah multikolinearitas pada data impor beras di Sulawesi Utara dimana terlihat nilai VIF pada regresi komponen utama bernilai satu untuk semua variabel komponen utama. Berdasarkan hasil analisis regresi komponen utama diperoleh model  = 48258,1804 + 0,006739247 X1 - 0,92939626 X2 - 0,06475365 X3 - 0,38551398 X4 + 0,0001233267 X5 + 5,365936 X6 + 0,0006384361 X7 + 0.0005029473 X8 - 3,25379897 X9 + 0,01069348 X10 dan koefisien determinasi (R2) = 90,36% dan nilai (Radj) = 85,53%.

The quantity that can be used to detect the presence of multicollinearity is Variance Inflation Factor (VIF). The purpose of this research is to determine the equation model of regression principal component, and to know the variables that influence on rice import in SULUT. The study used data of rice imports in North Sulawesi in 2006-2015. The data will be analyzed using regression analysis of principal components. Regression analysis of principal component can overcome the problem of multicollinearity in rice import data in North Sulawesi  where seen VIF value at regression of principal component is one for all principal component variable. Based on the analysis results of regression principal component, has obtained the model Y = 48258,1804 + 0,006739247 X1 - 0,92939626 X2 - 0,06475365 X3 - 0,3855139","PeriodicalId":17715,"journal":{"name":"JURNAL ILMIAH SAINS","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88915156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
