Summary: | As the project implementer, consultant and technical supervisor, the
contractor�s knowledge upon the road pavement construction method is one of the
factors related to the road pavement condition of the project. The objective of this
study was to analyze the correlation of contractor�s knowledge level and
perception to the road pavement condition in District of Sumba Barat.
The research instruments used in this study was questionaires distributed
to 102 respondents to obtain the comprehension level and perception of the
respondent. To obtain the data of road pavement surface condition, this study
applied the Pavement Condition Index (PCI) method, which included visual
inspection to 26 road sections. The Chi Quadrate testing was used to identify the
difference of respondent's perception to the road pavement work implementation
method. The Rank Spearman correlation coefficient analysis method and Partial
Correlation were used to analyze the relation, significance and hypothesis of this
study.
Based on this study, it can be concluded that the calculating results of the
correlation coefficient test indicated strong correlation between the contractor�s
comprehension level to the condition of road pavement surface. Based on the
Rank Spearman calculation, it was indicated that when hot mix pavement = 0,74,
the significance degree was Zhitung (1,28) � Ztabel (-0,063), and when lapen
pavement = 0,89, the significance degree was Zhitung (0,89) � Ztabel (-4,08). The
Partial correlation testing showed that when controlled by the road age, the hot
mix pavement indicated very strong correlation (0,90 approaching zero), but it
was insignificant when the calculation analysis showed Zhitung (0,90) � Ztabel
(0,950) . A lapen pavement was categorized as strong (0,7804) when the
calculation analysis was Zhitung (0,7804) � Ztabel (0,423). When controlled by the
contractor�s knowledge level, road with hot mix pavement indicated very low
correlation (-0,323 approaching zero) and it was insignificant when based on the
hypothesis testing of Zhitung (-0,323) � Ztabel (0,950). The same was applied for
lapen pavement, the correlation was very low (0,0153 approaching zero) and no
significant value obtained based on the hypothesis testing due to Zhitung (0,0153)
� Ztabel (0,432). |
