PENGARUH RANTAI PASOK DAN WAKTU TEMPUH & BIAYA TERHADAP SALURAN DISTRIBUSI PT PUPUK INDONESIA DI PROVINSI SUMATERA UTARA(Studi Kasus Pada Kelompok Tani di Kecamatan Tigalingga)

This study aims to analyze the effect of Supply Chain and Travel Time and Cost on the Distribution Channels of Subsidized Fertilizers in Tigalingga District. This research employed a quantitative method with an associative approach. The population consisted of farmers receiving subsidized fertilizers in Tigalingga District, while the sample comprised 100 respondents selected using a purposive sampling technique. Data were collected through questionnaires using a Likert scale. The data analysis included validity testing, reliability testing, classical assumption testing, multiple linear regression analysis, partial hypothesis testing (t-test), simultaneous hypothesis testing (F-test), and coefficient of determination (R²) analysis using IBM SPSS Statistics Version 26. The results showed that the Supply Chain variable had a positive and significant effect on Distribution Channels, with a t-value of 2.141 and a significance value of 0.035 < 0.05. The Travel Time and Cost variable also had a positive and significant effect on Distribution Channels, with a t-value of 4.733 and a significance value of 0.000 < 0.05. Simultaneously, the Supply Chain and Travel Time and Cost variables had a positive and significant effect on Distribution Channels, with an F-value of 13.029, which was greater than the F-table value of 3.09, and a significance value of 0.000 < 0.05. The coefficient of determination (R Square) was 0.212, indicating that 21.2% of the variation in Distribution Channels could be explained by the Supply Chain and Travel Time and Cost variables, while the remaining 78.8% was influenced by other factors outside the scope of this study. Furthermore, the Adjusted R Square value of 0.195 indicates that, after adjustment for the number of samples and independent variables, the model explains 19.5% of the variation in Distribution Channels.
