The influence of infrastructure expenditures from the Ministry of Public Works and Public Housing on the condition of national roads by province 2020-2021

Abstract

This research was conducted to determine the influence of the existing infrastructure budget at the Ministry of Public Works and Public Housing on the condition of national roads according to province during the 2020-2021 period. Model one uses a simple linear regression test to see the correlation and significance between stable road conditions and the infrastructure budget. Model two uses multiple linear regression tests with the Ordinary Least Square (OLS) method to see the correlation and significance between stable road conditions and infrastructure budgets, Activity Performance Indicators (IKK), real GRDP/constant prices (pdrbhk), and roads in Java and Bali (djabal). The linear regression results of Model 1 show a constant (α) = 1.040, meaning that even though the infrastructure budget variable with Good Road Conditions is zero, the constant remains at 1.040. Model 2 shows a constant (α) = 0.798, meaning that even though the infrastructure budget variable with Road Steady Condition is zero, the constant remains at 0.798. Model 1 coefficient β (X) = 0.443, meaning that if the infrastructure budget increases by 1%, the length of national roads in steady condition (good and fair) will increase by 0.443%. The deterministic coefficient r2 a is 0.425, meaning that 42.5% of the variation in the variable value of the length of national roads in steady condition (good and fair). Model 2 coefficient β (X) = 0.391, meaning that if the infrastructure budget increases by 1%, the length of national roads in steady condition (good and fair) will increase by 0.391%.
