Abstract

Public transport accessibility is essential for promoting equitable urban mobility and social inclusion, particularly in medium-sized cities experiencing rapid suburban expansion. In many Indonesian cities, the growth of peripheral settlements has outpaced the development of public transport networks, resulting in unequal accessibility between urban centers and peripheral areas. This study investigates the social consequences of these accessibility gaps for vulnerable population groups in three Indonesian medium-sized cities: Malang, Mataram, and Palu. A qualitative multiple-case study design was employed. Data were collected during January 2025 through field observations, document analysis, and semi-structured interviews with ten purposively selected participants representing public transport users, peripheral commuters, students, older adults, transport operators, drivers, government officials, and an academic. Interview transcripts were analyzed using thematic analysis through iterative open, axial, and selective coding to identify recurring patterns across the three case cities. The findings reveal consistent disparities in public transport accessibility between urban centers and peripheral areas. Urban centers were characterized by denser route networks, higher service frequency, shorter waiting times, and better first-mile and last-mile connectivity. In contrast, peripheral areas experienced limited route availability, infrequent and unreliable services, longer walking distances to stops, and inadequate pedestrian infrastructure. These accessibility gaps generated significant social consequences, including increased travel costs, delayed access to employment and education, restricted access to healthcare, reduced daily mobility, and greater dependence on private motorcycles, ride-hailing services, and family support. Older adults, persons with disabilities, students, low-income households, and peripheral residents were identified as the groups most adversely affected. The findings further indicate that accessibility inequality is reinforced by rapid suburban expansion, limited public funding, low commercial viability of peripheral routes, and insufficient integration between transport planning and land-use planning. The study concludes that improving public transport accessibility requires more than expanding route coverage. Equitable mobility depends on reliable service frequency, effective first-mile and last-mile connections, accessible pedestrian infrastructure, and integrated transport–land-use planning. Policy interventions should prioritize peripheral route expansion, feeder services, operational subsidies for socially necessary routes, and coordinated governance to reduce transport-related social exclusion and promote inclusive urban development in Indonesian medium-sized cities.

Abstract

Composite engineering is an important component in aviation vocational education, requiring both strong conceptual knowledge and precise practical skills. However, practical training in this field often faces challenges, including limited access to materials, expensive equipment, and high safety requirements. This study aims to design and evaluate the effectiveness of an Interactive Video-Supported Worksheet (IVSW) as a low-fidelity simulation-based learning medium to enhance cadets' conceptual understanding and practical competence in composite engineering, using the ADDIE model and a quasi-experimental one-group pretest–posttest design. Participants consisted of cadets enrolled in the Aircraft Composite Engineering course at Makassar Aviation Polytechnic. IVSW provides structured guidance through worksheets accompanied by instructional videos that demonstrate the procedures for fabrication and repair. Data were collected through pretest–posttest conceptual tests, observation rubrics for practical performance, and student perception questionnaires. Quantitative data were analyzed using paired sample t-tests and descriptive statistics. The results of this study indicate that combining structured worksheets with embedded instructional videos can serve as a low-impact yet highly effective simulation-based learning approach. This approach provides cognitive support and procedural modeling, enabling cadets to better integrate theory with practice. The findings show that cadets who used IVSW demonstrated improvements in theoretical knowledge (sig (2-tailed) = 0.012), as well as procedural accuracy, time efficiency, and the quality of composite fabrication and repair. However, alternative learning models are needed to enhance conceptual understanding, such as quizzes within videos, structured discussions, and clear learning instructions to improve a more significant understanding of concepts.

Abstract

This study investigates the geometric characteristics of airfoil sections in three fixed-pitch propellers used in general aviation training aircraft. The analysis focuses on the distribution of chord length, maximum thickness, and thickness ratio along the blade span. Measurements were conducted at ten radial stations, from 10% of the blade length to the blade tip, using precision measuring tools. Statistical analysis, including normality, homogeneity, and comparative tests, revealed no significant differences among the three propeller types in terms of these geometric parameters, allowing the use of averaged values for further interpretation. The results show consistent geometric trends across all propellers, with chord length and maximum thickness decreasing from root to tip, while the thickness ratio follows a similar pattern. The region around 70% of the blade span was identified as the most aerodynamically efficient, with an average thickness ratio of approximately 0.11. Additionally, differences between aluminum and wooden propellers were observed, with wooden propellers generally exhibiting higher thickness ratios due to material constraints, although these differences were not statistically significant. The study also highlights the aerodynamic implications of thickness ratio variation. Higher thickness ratios tend to increase lift and drag while reducing lift-to-drag ratio and stall performance, whereas thinner airfoils provide better aerodynamic efficiency and contribute more effectively to thrust generation. Overall, the findings emphasize the importance of balancing structural and aerodynamic considerations in propeller blade design and provide a useful reference for future research on airfoil geometry, including the role of maximum thickness location.
