systems unite by eliminating the independence of one
or both, but without losing their identities (Poltronieri
et al., 2017). The integration consists of three main
management systems: Quality Management System
(QMS), Environmental Management System (EMS),
and Safety Management System (SMS). The goal of
implementing a management system by integrating
several standards and documents is to achieve
synergistic action in the organization (Zgodavova and
Bober, 2012).
IMS can be done by using 3 approaches,
namely process integration, risk integration, and audit
integration (Paraschivescu, 2016). Process integration
is a method of combining part or all of the process to
reduce resource consumption and harmful emissions
to the environment (Klemes, Varbanov, & Kravanja,
2013). Bugdol et al (2015) explained that only 0-70%
of all processes are integrated with the integration
matrix (Bugdol & Jedynak, 2015). Bugdol (2015)
said that not all processes need to be integrated.
This research uses a process integration approach
that consists of 8 components, namely the scope
(1), leadership (2), integration of management policy
(3), planning (4), support (5), operational (6),
performance evaluation (7), and improvement (8)
(Rofi’udin, Masuin, & Latief, 2018).
The three standards of QMS, EMS, and
SMS are generally based on the principle of
continuous improvement by the Deming cycle
(Plan-Do-Check-ACT) (Zeng et al., 2010). The
PDCA cycle is a concept of sustainable business
enhancement and additional troubleshooting (Singh,
2013). The process integration of the third process
management system is also based on the PDCA
approach described in Figure 1.
Blue lines demonstrate leadership, integration of
management policy, scope, planning, supporter,
operational, performance evaluation, and
improvisation supporting the system to perform
process integration.
The red lines demonstrate PDCA cycle in process
integration and its correlation with management
system components. PDCA is an ongoing approach
of management system in the flow of planning,
implementation, checking and corrective action
(Ribeiro et al., 2017). The planning stages consist
of scope, leadership, and integration of management
policies. Leadership is needed to create the unity
of goals and direction and involvement of people
activating an organization to align strategies, policies,
processes and resources to achieve its objectives.
The Input of planning in the integration process
management system is the needs and expectations of
stakeholders as well as internal and external issues of
the organization that are reflected in the scope of the
system regarding organizational objectives and goals
(Mourougan, 2015).
The implementation stage requires operational
and supporting components. The operation of the
system must be done in accordance with the planned.
In operation, it takes resources that build, implement,
and maintain an integrated management system. The
required resources are on supporting components.
Performance evaluation should be done to the
results and services produced in the operational
phase. The result of performance evaluation was
made the foundation for a system improvement.
Organizations must find and filter opportunities for
improvement and take important actions to respond
to system sustainability objectives.
3 RESEARCH METHOD
This study uses two methods, respondents survey
and case studies. Respondents survey is suitable
to answer what and how large the correlation of
each survey variable. Analysis of surveys is useful
for identifying a thing (Yin, 2013). Therefore, this
strategy is used to identify risks in the integration
of process management systems that impact the
objectives of IMS components on construction
company organizations. The samples taken in this
research survey strategy are purposive samples. In
accordance with the research restrictions that have
been included in the research constraints in the first
chapter, selected respondents are the stakeholders of
the construction management (government or private
owned) implementing QMS, EMS, and SMS.
Case studies are used to investigate a small
number of cases in depth, such as the study of why a
project failed (Tan, 2011). The case study strategy is
suitable for answering the question ”How and why”
(Yin, 2013). Yin (2013) argues that this strategy
is conducted without controlling the characteristic
errors of the events studied and the research focuses
on contemporary events. The case studies research
strategy is due to questions relating to operational
relationships that need to be tracked over time, rather
than sheer frequency or incidence. This strategy is
suitable for use in this research as it can answer
strategies for managing the dominant risk, so that
the objectives of the integrated management system
components can be achieved.
