Abstract

Runways are crucial components of airport air transportation systems, serving as the primary surfaces for aircraft takeoffs and landings. To withstand the repetitive loading from various aircraft types, runway pavements must be designed with precise thickness in accordance with applicable technical standards. Despite the availability of various design guidelines, a notable research gap exists in the comparative evaluation of these methods for high-traffic runways to balance structural safety with modern economic and environmental sustainability goals. This study addresses this gap by analyzing the pavement thickness of Runway 3 at Soekarno-Hatta International Airport using two widely applied calculation methods: the Federal Aviation Administration (FAA) method and the Load Classification Number (LCN) method. The analysis utilized secondary data obtained directly from PT Angkasa Pura II, encompassing the dominant aircraft type (Boeing 737-800), annual aircraft movement volume, subgrade California Bearing Ratio (CBR) value (6%), and the specifications of the applied pavement materials. Calculations indicate that the FAA method requires a total pavement thickness of 990 mm, whereas the LCN method yields a lower thickness requirement of 889 mm. These findings demonstrate that the LCN method is more efficient than the FAA method within the context of Runway 3. The practical implications of this 101 mm difference in thickness are highly significant; the application of the LCN method directly contributes to reduced construction costs, minimizes material consumption, and supports sustainability objectives by lowering carbon emissions during the production and construction phases. In conclusion, this study strongly recommends the adoption of the LCN method in the development of modern airport infrastructure, as it has proven capable of meeting stringent safety standards while comprehensively optimizing economic efficiency and infrastructure sustainability.

Abstract

This study aims to identify and evaluate the risks affecting toll road revenue reduction and to develop mitigation strategies to enhance the resilience of the toll road sector. Case studies were conducted on the Semarang–Batang and Bali–Mandara toll roads. Using a combination of literature review, expert validation, and stakeholder surveys, 22 risk variables were identified and analyzed through a probability-impact matrix and descriptive methods. Results show that the most critical risk on the Semarang–Batang toll road is the delay in toll rate adjustments due to failure to meet Minimum Service Standards (SPM), which scored the highest severity value (15.000) and is classified as an extreme risk. In contrast, the Bali–Mandara toll road’s top risk is inflation rate fluctuations, with a severity score of 16.174. These differences are attributed to regional characteristics, surrounding infrastructure, and local economic conditions. Proposed mitigation strategies include government-backed revenue guarantees, concession extensions, flexible tariff policies, and improved operational and maintenance practices. Risk handling also incorporates traffic projection reviews and feasibility-based scenario planning. The findings of this study provide valuable insights for toll road operators (BUJT) and policymakers to develop risk management strategies that support the sustainability of toll road operations, particularly under uncertain conditions such as pandemics or global economic pressures.

Abstract

Banyuwangi Regency, located in East Java, Indonesia, has rapidly emerged as a leading tourism destination due to its exceptional natural beauty and cultural richness. The increasing number of domestic and international tourist visits requires adequate transport infrastructure to ensure accessibility and connectivity across major destinations. Without a well-functioning transport system, the tourism sector may face barriers to sustainable growth and equitable regional development. Accessibility is defined as the ease with which tourists can reach specific destinations, whereas connectivity reflects the degree of linkage and travel efficiency between those destinations. This study seeks to analyze the performance of the tourism transport system in Banyuwangi by applying the Hansen accessibility model, using both to assess spatial accessibility and inter-destination connectivity. Primary data were collected by measuring the distances between selected tourist destinations (ODTWs) along existing transport routes through Google Maps. Secondary data were obtained from the Banyuwangi Regency Tourism Office, including records of tourist arrival volumes. The results show that accessibility values range from 0.0067 to 0.07, while connectivity values vary between 0.87 and 1.09. These findings reveal significant disparities in transport service distribution and functional integration between routes. The study emphasizes the urgent need for strategic planning and investment in transport systems tailored to the dynamics of tourism flows. Enhancing transport accessibility and connectivity is essential not only to support tourist mobility but also to promote inclusive and sustainable tourism development across the region.

Abstract

Mahar Martanegara Road in Cimahi City serves as a strategic urban corridor connecting Cimahi and Bandung, characterized by high traffic volume influenced by surrounding industrial, residential, and commercial land use. The volume-to-capacity ratio approaching saturation conditions has increased traffic conflicts and accident risks in recent years. This study identify and analyze accident prone locations (blackspots) along Mahar Martanegara Road using the Equivalent Accident Number (AEK), Upper Control Limit (UCL), and Upper Control Boundary (BKA) methods. Accident data from 2022–2024 obtained from PT Jasa Raharja were analyzed and segmented per 300 meters. The AEK was calculated using weighted severity values for fatalities and injuries, and the results were statistically evaluated using BKA and UCL thresholds. The analysis indicates that two road segments categorized as blackspots is STA 0+600–0+900 and STA 2+400–2+700. The AEK values for these segments are 27 and 33, respectively, exceeding the BKA value (25.69) and their corresponding UCL values STA 0+600–0+900 (23.99) and STA 2+400–2+700 (24.94). These findings suggest systematic accident patterns beyond normal statistical variation. Contributing factors include high traffic density, the presence of heavy vehicles, roadside activities, inadequate safety facilities, and geometric and operational constraints. The results provide a data driven basis for local government intervention through traffic engineering improvements, enhancement of road safety facilities, regulation of heavy vehicle movement, and integrated road safety management strategies.
