Abstract

Maritime transportation activities contribute to Greenhouse Gas (GHG) emissions. IMO adopted MARPOL Annex VI to prevent air pollution from ships. Several countries in the world have initiated the use of electric ships as a form of campaign. The Indonesian government also shows its commitment to reducing GHG emissions and encourages the use of electric transportation in the transportation sector. The government issued various policies supporting the use of electric transportation. However, electric transportation in Indonesia is still dominated by the land sector. The adoption of electric ships for some shipowners is still only a discourse that has not been realized, one of which is PT Pertamina Trans Kontinental (PTK). This study aims to analyze the influence of green shipping campaigns and GHG emission reduction policies on the procurement of electric ships mediated by shipowner perceptions. The method used is mixed methods with PLS-SEM analysis to 97 respondents followed by interviews with 5 informants determined by purposive sampling. The results show that green shipping campaigns have a significant effect on shipowner perceptions, and GHG emission policies have a significant effect on the procurement of electric ships. However, the relationship between green shipping campaigns and ship procurement and GHG reduction policies on perceptions is equally insignificant. Shipowner perceptions significantly mediated the effect of campaigns on electric ship procurement, but not the effect of GHG emission reduction policies. The implementation of electric ships in PTK is hampered by technical, operational, economic, regulatory, and sustainability awareness factors.

Abstract

Purpose: This study explores the strategic role of Human Resource Management (HRM) practices training and development, performance management, and organizational innovation in improving transportation performance and safety in Indonesia, while examining the moderating effect of employee welfare amid growing digital transformation and rising safety standard demands. Methodology: A quantitative approach was employed using Partial Least Squares Structural Equation Modeling (PLS-SEM). Data were collected from 360 respondents working in the land transportation sector across Indonesia through structured questionnaires. Results: The findings confirm that training and development, as well as performance management, significantly influence both organizational innovation and transportation safety. Organizational innovation also positively affects transportation performance, which in turn enhances safety. However, the moderating effect of employee welfare on the innovation–performance relationship was found to be statistically insignifican. Conclusions: High-quality HRM practices in training and performance management enhance operational performance and safety in Indonesia’s transportation sector. However, innovation’s full benefits require stronger welfare systems and integrated safety training, performance tracking, and inclusive innovation within HR strategies for workforce resilience. Limitations: This study finds employee welfare has not significantly moderated transportation performance through innovation. Most welfare initiatives remain basic and unaligned with strategic agendas, revealing a gap between employee well-being and organizational goals that may hinder long-term innovation sustainability. Contribution: This study validates the impact of training and performance management on transportation innovation and safety in developing countries, offering a framework for aligning HR strategies with digitalization and safety goals while emphasizing welfare policies that actively support innovation and performance excellence.

Abstract

This study examines the effects of the transportation and warehousing sector, tourism, and agriculture, forestry, and fisheries on economic growth, with Local Own-Source Revenue (PAD) serving as an intervening variable in regencies traversed by the Trans-Sumatra Toll Road (JTTS) in Lampung Province. The research covers six regencies—South Lampung, Central Lampung, Mesuji, Pesawaran, Tulang Bawang, and West Tulang Bawang—over the period 2020–2024, producing a balanced panel dataset of 30 observations. Panel data regression is applied using the Random Effects Model (REM), selected through Chow, Hausman, and Lagrange Multiplier tests. The mediating role of PAD is analyzed using the Sobel test. The results indicate that transportation and warehousing have a positive and statistically significant effect on economic growth. Similarly, agriculture, forestry, and fisheries also show a positive and significant direct effect on economic growth. In contrast, tourism exhibits a negative and significant direct effect, suggesting limited multiplier effects during the observation period. PAD does not have a statistically significant direct effect on economic growth. In the PAD model, only agriculture, forestry, and fisheries demonstrate a positive and significant influence, while transportation and warehousing and tourism do not significantly affect regional revenue. Mediation analysis reveals that PAD significantly mediates the relationship between transportation and warehousing and economic growth, as well as between agriculture and economic growth. However, PAD does not mediate the effect of tourism on economic growth. Overall, the findings suggest that the economic impact of the Trans-Sumatra Toll Road in Lampung Province operates primarily through improvements in logistics efficiency and enhanced agricultural distribution networks, with selective fiscal transmission effects. These results highlight the importance of integrating infrastructure development with sectoral upgrading and effective fiscal management to ensure sustainable and inclusive regional economic growth.
