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.

Abstract

ISO issued the ISO/IEC 27001:2022 standard in October 2022 to update ISO/IEC 27001:2013 with the main objective of improving the relevance of the standard to the current state of information security, ensuring simpler and more effective controls, and facilitating better risk handling. The transition period given is for 3 years since the latest standard was published in October 2022, ISO provides a transition period until October 31, 2025 so that organizations can adjust their information security management systems to the latest version. After that date, ISO/IEC 27001:2013 certification is declared invalid, and all organizations that want to maintain their certification must comply with the latest ISO/IEC 27001:2022 standard.The proposed solution from this research is thirteen action plans to be implemented by PT PKT to close the identified gaps and to meet all the requirements in ISO/IEC 27001:2022. The action plans are grouped according to Plan-Do-Check-Action (PDCA) cycle adopted by ISO as the basis for consideration in preparing the implementation time frame. The results of the research showed that PT PKT could make a transition in eight months. The implementation of proposed action plan starts in July 2024 and will completed in February 2025, which means that PT PKT can successfully transition ISO/IEC 27001:2022 before the due date.

Abstract

PT Bukit Asam Tbk (PTBA) is a leading coal mining enterprise with a vital role in supplying energy for both domestic consumption and export markets. One of the company’s major challenges lies in managing laycan schedules, which can trigger operational risks, intensify port congestion, and hinder the coal loading process. This study aims to identify operational risks associated with laycan that lead to demurrage and to propose strategies to mitigate these risks at Tarahan Port. The research applies a gap analysis framework supported by Failure Mode and Effect Analysis (FMEA). Data were collected through both primary and secondary sources. Primary data involved focus group discussions designed with FMEA to assess severity, frequency, and detection levels, with insights from thirteen informants: eight from the distribution division, one port supervisor, and four operational support staff. Secondary data were drawn from historical records spanning 2023–2024. The analysis incorporated FMEA and Root Cause Analysis (RCA). Findings revealed 25 root causes using the 5 Why method. The top risks included loading delays at jetty 3, simultaneous vessel arrivals, domestic jetty queues, export documentation delays due to surveyor systems. Recommendations emphasize addressing urgent loading bottlenecks, implementing phased solutions, enhancing cross-team coordination, and ensuring continuous monitoring.

Abstract

The issue of global warming and the increasing concentration of carbon dioxide (CO₂) represents a significant environmental challenge, with the transportation sector contributing approximately 23% of global greenhouse gas emissions. One of the crucial problems is the operation of Over-Dimension Over-Load (ODOL) trucks, which generate serious negative environmental and social impacts. This study conducts a socio-environmental evaluation of ODOL trucks from the perspectives of carbon emissions and carbon tax, and further analyzes the acceptance of the Zero ODOL and Carbon Tax policies in Indonesia. The technical evaluation involves simulates fuel consumption, CO₂ emissions, and carbon tax burdens based on ODOL truck travel data. Meanwhile, the social evaluation is conducted through a survey of two respondent groups, namely truck drivers (97 respondents) and the general public (214 respondents), using a questionnaire that integrates constructs from the Health Belief Model (HBM), risk perception, user cost, law enforcement knowledge (LEK), and the Policy Acceptance Model (PAM). The technical findings indicate that ODOL trucks have higher fuel consumption, CO₂ emissions, and carbon tax burdens compared to non-ODOL trucks. From the social perspective, acceptance of the Zero ODOL policy is influenced by different determinants across the two groups. For drivers, policy acceptance is highly sensitive to economic-based instruments such as carbon tax and knowledge of sanctions. In contrast, the general public is more driven by safety perception, traffic order, and the social impacts of road disturbances. These findings emphasize the importance of tailored policy implementation strategies, where economic incentive–based approaches are more effective for drivers, while safety- and public order–based approaches are more resonant for the public.
