THE SIGLI-BANDA ACEH TOLL ROAD PROJECT

ABSTRACT
Effective management of risk is critical to the success of any construction project. The importance of
risk management has grown as projects have become more complex. This study examines the influence
of risk factors on project cost in the Sigli-Banda Aceh toll road project. It identifies 47 common risk
indicators and categorises them into six risk factors, emphasize the need for improved risk management
strategies in complex construction projects. The research question of this study is to know the influence
and relationship of risk factors on project cost in the Sigli-Banda Aceh toll road project. The purpose of
this study is to determine the risk factors that influence and relate to project cost in the Sigli-Banda Aceh
toll road project. The data was analysed with statistical tools to determine the rank of factors affecting
project costs. The research method used quantitative, using hard data on Likert scale, and qualitative,
using the opinions of the respondents, with primary sources and secondary data. This research involved
the project director, site supervisors, engineers, safety environment officer, and finance manager from
PT Hutama Karya. Data collection techniques include the distribution of questionnaires. The data
analysis technique uses correlation and multiple linear regression analysis methods with the help of SPSS
software. According to the result analysis, all the factors have a moderate relationship with the project
cost, and there are four factors that have a significant relationship with the project cost, namely material
risk, equipment risk, construction method risk, contractor managerial risk, and construction safety risk.

INTRODUCTION
Construction is a big industry in Indonesia, as it is in other nations, and it plays a vital role
in the expansion of socioeconomic development (Khan et al., 2014). The primary criterion for
project success is meeting the project's deadlines and budget while maintaining the required level
of quality (Serrador & Turner, 2015). Although there has been significant investment in the
construction sector in Indonesia, there are still several problems with the sector, including costs
that exceed budgets, delays in finishing projects on time, construction faults, and an overreliance
on foreign labour (Menolascina et al., 2008).
The construction sector is facing a significant cost-cutting challenge as a result of the
expanding demand for building of all kinds and the limited availability of funding (Sami Ur
Rehman et al., 2022). Corporations, institutions, and the government would be in a survival race
for the remainder of the twentieth century, according to Mendelson and Greenfield (1996). The
participant in these sectors (the customer, in particular) is prepared to take on the challenge of
assuring efficient use of their resources to achieve value for money in terms of performance due
to the accompanying diminishing economic fortune of nations' economies throughout the world
(Eshofonie, 2008).
Under typical conditions, it is anticipated that the following costs will add up to the overall
cost of construction: Materials, labour, site overheads, equipment/plant, head office expense, and
profit, however in many countries, particularly in Indonesia, there are other costs that need to be
taken into account (Eshofonie, 2008).
These costs clearly have a negative impact on both the industry as a whole and the major
stakeholders in particular. High cost means additional costs to the client beyond those previously
discussed at the outset, resulting in worse returns on investment. The additional expenses are
passed on to the consumer as higher rental or leasing fees or prices. The consultants interpret this
as a failure to provide value for the money spent, which could damage their reputation and cause
clients to lose faith in them. If the contractor is at fault, it means a loss of earnings due to penalties
