Abstract

Abstract: Environmental degradation require business to rethink their way of doing business. Industrial Ecology (IE) is a paradigm change that allows a cyclical resource-use in which Circular Economy (CE) rethink and recycle the waste generated into a industrial input, thereby reducing environmental burden. Industrial Ecology (IE) is one of the most referenced grand theories for Circular Economy (CE). This research aims to map IE to CE bibliographically to identify research trends, prominent researchers, and countries with the most publication. This research's methodology is bibliographic mapping of 112 articles using VOSviewer in three steps: data acquisition, data processing, and visual output. This research has identified three research findings. The first finding is the identification of five clusters that correspond with the current research trend. The second finding is identifying Geng Y., Lai K.H., and Zhu Q. as the leading researchers for CE and IE. The third finding is China is the leading country for CE and IE research. The implication is China aiming to transform its industry into environmentally more sustainable. Future research topic venue can incorporate other grand theories to expand the theoretical and practical focus of CE.

Abstract

Engineering, procurement and construction (EPC) projects place a single contractor in charge of design, materials and construction under tight time and cost targets. In Indonesia many projects also rely on subcontractor labor and owner supplied materials, which increases coordination risk. PT GTU experienced a failure on a piping project for a paper mill in Riau, known as BM4. This thesis examines why the project moved away from its plan and what kind of project management system could have reduced the likelihood of failure. BM4 is analysed as a single case. The study assumes that complex projects usually fail because of an accumulation of management choices rather than one event. It aims to identify the key factors behind the failure using the six project constraints as a frame, to explain how they affected schedule, site readiness, subcontractors and cash flow, and to develop a project management system tailored to GTU. A qualitative design is used. Data comes from semi structured interviews with seven internal stakeholders and from supporting project documents. The material is coded by project constraints, analyzed using Current Reality Trees to link visible symptoms to root causes, and compared with selected PMBOK Guide Sixth Edition processes as a benchmark for expected practice. The results indicate three main root causes: lack of project leadership and discipline, absence of formal change control and unrealistic schedule and resource baselines. Together they explain the difficulties in BM4, including unstable subcontractor manpower, coordination problems and repeated quality issues. The thesis concludes by proposing a practical project management system for GTU that clarifies governance routines, introduces an integrated change control procedure and strengthens rules for setting and updating baselines to support future EPC projects.
