Abstract

Regulatory and Operational Impacts on Indonesia’s Shipbuilding Costs: This study aims to quantify the impact of regulatory and operational delays on shipbuilding costs in Indonesia, a maritime nation undergoing rapid infrastructure modernization. Grounded in the theoretical frameworks of institutional economics and project risk management, the research investigates how permit duration and project delays affect the financial performance of nationally significant vessel construction projects. Employing a quantitative approach, data from 14 real-world shipbuilding projects including patrol boats, offshore patrol vessels (OPVs), tankers, and submarines were analyzed. Key variables comprised total project cost (in billion IDR), permit time (months), and project delay duration (weeks). Descriptive statistics, Pearson correlations, and multiple linear regression were performed, followed by robust regression and outlier diagnostics (Cook’s Distance and VIF analysis) to ensure model reliability. The results reveal that project delays significantly increase total costs (p < 0.001), whereas permit duration exhibits a negative but context-dependent relationship. The model explains 68% of cost variation (R² = 0.68), with multicollinearity between permit time and delays (r = 0.94) indicating the need for cautious interpretation. Robust regression and diagnostic tests confirm the influence of high-cost defense projects as outliers. These findings provide actionable insights for maritime infrastructure policy, highlighting the need to streamline permit procedures, enhance inter-agency coordination, and mitigate project execution delays. This research contributes novel empirical evidence from real project data and applies advanced diagnostic techniques, addressing a critical gap in Southeast Asian maritime economics literature.

Abstract

Occupational safety on board ships is a crucial aspect that must be fully considered, especially in high-risk Anchor Handling Tug Supply (AHTS) vessel activities. This study aims to conduct a safety risk assessment on AHTS vessel activities using the Hazard and Operability Study (HAZOP) method. The research method used is descriptive qualitative, which involves direct observation, interviews, and documentation analysis to obtain comprehensive data on potential hazards and operability in AHTS vessel activities. Some key findings include the identification of often overlooked potential hazards, such as adverse weather conditions, poorly maintained equipment, and non-compliance with safety procedures. Based on the HAZOP analysis used in this study, these risks will be categorized into three levels: low risk, moderate risk, and high risk. The analysis shows that most risks are at the moderate risk level, which requires a planned control approach and temporary measures to reduce the risks. Implementation of recommended mitigation measures, such as regular training on occupational safety, better equipment maintenance, and strict supervision of procedural compliance, can shift the risks from the moderate to low risk level. Effectively implementing the HAZOP method can improve occupational safety on AHTS vessels.
