The results of this study indicated that simultaneously the land transportation variable and manufacturing industry have a positive and significant effect on the economic improvement variable. The results obtained a tcount value of 3.599. Thus tcount is greater than t table (3.241> 1.894); then H0 is rejected HA is accepted, meaning that partially there is a positive and significant influence between land transportation and economic improvement. The results obtained a tcount of 0.112. Thus tcount is greater than t table (0.112 <1.894) then H0 is accepted HA is rejected, meaning that partially there is no positive and significant influence between the manufacturing industry on economic improvement.
