Abstract

The purpose of this research are to analyze the influence of container crane productivity (X1)
and ship call frequency (X2) on the number of containers handled (Y) at Terminal Petikemas
Semarang branch PT. Pelabuhan Indonesia III. The tool of analysis which was used was
Multiple Regression with Classic Assumption Test. This research used secondary data obtained
from TPKS such as monthly report the achievement of performance, monthly report of ship call
and monthly report of stevedoring production within period of 6.5 years (January 2009 ”“ June
2015).The Result of the Multiple Regression Analysis was Log Y = 4.923991 + 0.525387 log XI
+ 0.423276 log X2 + e. This equation showed that all regression coefficients were positive. It
means that if container crane productivity and ship call frequency was increased, the number of
the containers handled would increase too.β
1
= 0.525, it means that if there is increase in
container crane productivity by 10%, it will increase the cargo handling performance by 5.25%.
Next, β
= 0.423, it explains that if there is an increase in ship call frequency by 10%, it will
increase the cargo handling performance by 4.23%. The result of Coefficient of Determination of
Test shows that container crane productivity and ship call frequency give the proportion or
percentage of the total variation in the number of containers handled for about 94,8%. While, FTest

shows that container crane productivity and ship call frequency influenced simultaneously
on the number of containers handled. Furthermore, container crane productivity influenced
positively on the number of containers handled. Then the other X variable, ship call frequency
influenced positively on the number of containers handled.

Key words: Container Crane, Ship Call, Cargo Handling and Port.
