Abstract

This study investigates the impact of third-party logistics (3PL) outsourcing on the efficiency of Indonesia’s manufacturing sector, a key industry burdened by high logistics costs, infrastructural deficiencies, and regulatory fragmentation. The objective is to determine whether 3PL adoption enhances logistics performance by reducing costs, improving scalability, and mitigating operational inefficiencies. Employing a mixed-method approach, the research draws on secondary data from industry reports and academic literature. Key performance indicators such as logistics cost structures, response time to demand changes, and integration risk severity were analyzed to compare in-house logistics operations with outsourced 3PL models. Results demonstrate significant cost reductions through 3PL - 41.7% in warehousing, 40% in transportation, and 20% in labor alongside enhanced scalability and responsiveness. 3PL providers achieved higher adaptability in managing demand fluctuations, requiring only 3 weeks to scale up operations versus 8 for in-house logistics. However, risks including IT system mismatches (72% frequency), SLA misalignments, and data security concerns were also prevalent. The findings confirm that 3PL offers a viable solution for improving logistics efficiency, provided that integration risks are carefully managed. Long-term 3PL partnerships yield financial as well as strategic benefits, including access to advanced technologies and greater operational agility. For Indonesia to fully realize the advantages of 3PL, coordinated efforts are needed from both the government and private sector to address regulatory bottlenecks, improve infrastructure, and support digital transformation.

Abstract

Global supply chains have become highly vulnerable to disruptions caused by pandemics, geopolitical conflicts, trade wars, and sustainability pressures. This narrative review synthesizes existing research on risk management strategies with a focus on resilience, collaboration, sustainability, and strategic intelligence. Literature searches were conducted in Scopus, Web of Science, and Google Scholar, covering studies published between 2010 and 2024. The findings highlight resilience strategies—such as redundancy, agility, and digitalization—as essential mechanisms for mitigating disruptions. Redundancy reduces operational vulnerabilities through buffer inventories and multiple sourcing, while agility enables rapid adjustments to volatile conditions. Digitalization further enhances resilience by improving real-time monitoring and decision-making. Collaborative governance and risk-sharing contracts strengthen supply chain networks by fostering trust and distributing risks equitably. Geopolitical events and the COVID-19 pandemic illustrate the fragility of global networks, emphasizing the importance of supplier diversification, localization, and technological preparedness. Sustainability-related risks, including environmental, social, and governance (ESG) issues, require integrated frameworks that align resilience strategies with ethical and regulatory imperatives. Strategic intelligence emerges as a dynamic capability that supports proactive adaptation and recovery. This review concludes that effective supply chain risk management requires integrated and adaptive frameworks combining resilience, collaboration, and intelligence. Policy support, investment in logistics infrastructure, and targeted strategies for small and medium-sized enterprises (SMEs) are critical for building sustainable and competitive global supply chains in an increasingly uncertain environment,

Abstract

Ports play a strategic role in maritime logistics but also contribute substantially to carbon emissions through cargo-handling equipment, terminal electricity consumption, vessel berthing activities, and landside transport operations. This study aims to examine the effects of equipment electrification, shore-power availability, renewable-electricity utilization, digitalization, and operational efficiency on carbon-emission intensity in Indonesian port operations while evaluating the potential of integrated green-port strategies for emission reduction. The study employs a quantitative panel-data approach using a balanced dataset of 32 port-year observations from eight major Indonesian ports covering the 2021–2024 period. Total operational emissions are estimated from diesel consumption, electricity use, and vessel-hotelling activities, while carbon-emission intensity is measured as tonnes of carbon dioxide per 1,000 throughput units. Panel-regression analysis is specified to evaluate the relationships between technological and operational variables and emission intensity, complemented by policy-scenario simulations assessing the effects of equipment electrification, shore power, renewable electricity, digital operational optimization, and an integrated green-port package. The results indicate that average operational emissions declined from 12,612.66 tCO₂ in 2021 to 6,790.22 tCO₂ in 2024, representing a 46.16% reduction. Carbon-emission intensity decreased from 17.09 to 8.53 tCO₂ per 1,000 throughput units, equivalent to a 50.09% improvement in environmental efficiency. During the same period, equipment electrification increased from 9.18% to 48.80%, while average vessel berth time declined from 42.13 to 29.68 hours. The average Green Port Index reached 55.93 in 2024, indicating a medium-to-high level of sustainability transformation. Scenario analysis suggests that additional equipment electrification could reduce operational emissions by approximately 18%, universal shore power by 9%, renewable electricity by 7%, and digital operational optimization by 8%. When implemented simultaneously, the integrated green-port package is estimated to reduce operational emissions by approximately 36.1%, demonstrating that coordinated technological and operational interventions generate greater environmental benefits than isolated measures. The study concludes that successful port decarbonization requires the integration of clean technologies, low-carbon electricity, operational digitalization, and efficiency improvements rather than reliance on a single mitigation strategy. The proposed panel-data framework and Green Port Index provide practical tools for evaluating port sustainability and supporting evidence-based policy development. These findings contribute to the growing literature on sustainable maritime logistics and offer policy guidance for accelerating the transition toward low-carbon port operations in Indonesia and comparable emerging maritime economies.

Abstract

Public transport accessibility is essential for sustainable urban mobility, yet disparities between urban centers and peripheral areas persist in many Indonesian medium-sized cities. This study examines how residents, operators, and local governments in Malang, Mataram, and Palu perceive these disparities and identifies factors shaping accessibility inequality and its implications for equitable transport planning. A qualitative comparative multiple-case study design was used, involving thirteen purposively selected informants—urban and peripheral residents, vulnerable groups, operators, and planners—through semi-structured interviews, field observations, and policy document analysis. Data were analyzed using the Miles, Huberman, and Saldaña thematic analysis framework via open, axial, and selective coding. Findings show significant disparities: central residents enjoy shorter access distances, higher frequency, better connectivity, and reliability, while peripheral communities face longer distances, weak first/last-mile connections, limited hours, higher costs, and reliance on informal transport. Barriers are especially severe for persons with disabilities, older adults, women, students, and low-income residents, linking transport disadvantage to social exclusion. Institutional constraints—limited budgets, uneven investment, declining ridership, and urban-centered planning—sustain these inequalities. Residents adopt adaptive strategies (motorcycle taxis, ride-sharing, schedule adjustments) that shift the burden onto individuals rather than resolving structural issues. The study concludes that accessibility disparities are multidimensional, requiring integrated feeder services, inclusive infrastructure, equitable investment, and stronger transport–land-use coordination, informed by Accessibility Theory, Transport Equity, and Center–Periphery perspectives.

Abstract

Public transport accessibility is fundamental to sustainable urban mobility, yet conventional GIS-based spatial indicators often fail to capture commuters' lived experiences. This study integrates GIS-based and perception-based accessibility measures to provide a more comprehensive understanding of conditions in Indonesian medium-sized cities. A qualitative multiple-case study design was conducted across four cities—Malang, Mataram, Pontianak, and Kendari—involving fourteen informants including commuters, operators, planners, elderly passengers, and a person with disability. Data were gathered through semi-structured interviews, field observations, document review, and spatial analysis, then analyzed using open, axial, and selective coding alongside cross-case comparison, integrating spatial and qualitative findings. Results reveal that objective spatial accessibility and perceived accessibility are often inconsistent, producing four typologies combining high/low spatial and perceived accessibility. Key factors shaping perceived accessibility include walkability, sidewalk continuity, pedestrian safety, service reliability, waiting time, route suitability, information availability, intermodal integration, and inclusive infrastructure. Some residents near transit stops reported poor accessibility due to discontinuous pedestrian infrastructure and unreliable services, while others accepted longer walking distances when services were predictable and affordable—showing accessibility depends on the entire travel experience, not just spatial proximity. The study concludes that GIS indicators should be complemented by perception-based measures, offering an integrated framework to identify mismatches between infrastructure and commuter experience and support inclusive, user-centered transport planning in Indonesian medium-sized cities.

Abstract

The presence of large-scale educational institutions in rural areas can trigger significant economic and social change for surrounding communities, as seen in Blimbingsari Village, Rogojampi District, Banyuwangi Regency, since the Indonesian Pilot School Banyuwangi (APIB) began operating. This study examines how APIB's economic local economic linkages influences residents' income and the social transformation that follows. Unlike previous studies focused on airports or commercial plantations, this research fills a gap in the rarely studied context of agrarian-fishing villages directly adjacent to aviation academies, combining qualitative and quantitative analysis in one case study. Data were collected through in-depth interviews with 24 informants and questionnaires from 64 respondents in Blimbingsari Village. Results show APIB's impact is differential: business actors gained the most direct economic benefits, farmers and fishermen experienced greater social change, and housewives recorded the highest expectation scores despite moderate perceived benefits. The study enriches growth center theory, showing that benefit distribution from an anchor institution depends on each group's interaction with it, underscoring the need for village economic resilience through BUMDes optimization and business diversification, reducing dependence on one institution.
