Abstract

This study aims to evaluate the impact of Performance-Based Navigation (PBN) implementation on airspace safety across ASEAN countries. Amid growing aviation traffic and the International Civil Aviation Organization (ICAO) push for harmonized air navigation strategies, ASEAN's PBN readiness varies significantly, warranting a regional assessment. Guided by the International Civil Aviation Organization (ICAO) Global Aviation Safety Plan (GASP) and Doc 9613 PBN Manual, this research investigates how integrating advanced navigation procedures and aligning policies contribute to improved safety outcomes. A comparative quantitative analysis was conducted using secondary data from 11 ASEAN countries between 2009 and 2023. Key variables include the PBN Coverage Index, Fleet RNAV Capability, Policy Alignment, and Safety Risk Index. Statistical methods included descriptive statistics, Pearson correlation, OLS regression, ANOVA, and hierarchical clustering. Regression results reveal that policy alignment with ICAO standards significantly reduces safety risk (p < 0.05), while higher PBN coverage shows a strong negative correlation with risk levels (r = –0.80). ANOVA indicates statistically significant differences in safety performance across readiness levels. Clustering analysis distinguishes three country groups, with Indonesia, Singapore, and Thailand leading in PBN readiness. The findings highlight the need for harmonized regional aviation strategies, particularly in countries with limited infrastructure, such as Timor-Leste. Strengthening regulatory compliance and technological adoption is essential for safety enhancement. This study offers integrated multi-method analysis of PBN implementation and safety outcomes in ASEAN, contributing empirical insights for aviation policymakers and ICAO stakeholders.

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.
