This study discusses the implementation of multimodal transportation policies in Papua, as an effort to address the high cost of goods in the region with the aim of reducing logistics costs and accelerating economic growth. Shipping rates in Indonesia remain an unresolved issue, especially in the Papua region, classified as a 3T area (lagging, frontier, and outer), leading to high commodity prices. The research employs bibliometric analysis using the Scopus database as its data source. Out of a total of 5,930 articles found, a filtering process considering location, keywords, and a time range from 2009 to 2023 was conducted. As a result, 200 relevant articles were identified for analysis, and from this pool, 15 articles most aligned with relevant keywords were selected as the primary references for this study. The research findings indicate that the implementation of multimodal transportation policies in Papua has successfully reduced price disparities and improved accessibility to mountainous regions. However, challenges persist in the development of multimodal transportation in 3T areas, prompting recommendations for policies such as collaboration and logistics integration across modes, seaplane transportation, and mountain flying training to optimize logistics delivery in mountainous areas. Additionally, the use of unmanned aerial vehicles (drones) for more efficient logistics delivery is suggested. Furthermore, future research should focus on various aspects of multimodal transportation, including ride-sharing, mobility as a service, railway transportation, traffic congestion, land use, climate change, greenhouse gas emissions, traffic control, transportation costs, safety, travel time, social welfare, and expenses. This study provides insights into the positive impact of multimodal transportation policies in Papua and offers guidance for future development to address the issue of high commodity prices in 3T regions.

effectiveness of Apron Movement Control (AMC) supervision in developing a safety culture at the apron of a major airport in North Sumatra. It was motivated by a collision between a Lavatory Service Truck (LST) and a Boeing 737-800 aircraft on October 16, 2024, caused by personnel negligence, unserviceable equipment, and weak supervision. Methodology: A qualitative case study approach was applied. Data were collected through observation, interviews, and documentation, and analyzed thematically using NVivo 15. The ORLIO model was employed to evaluate human error. Result: The study identified repeated violations—normalization of deviance among Ground Support Equipment (GSE) personnel, limited AMC supervision, and non-compliant equipment. ORLIO-based evaluation enhanced personnel reflection and safety awareness, while AMC supervision acted as external enforcement. The synergy between reflection and supervision contributed to a shift in apron safety culture from permissive toward a more mature and sustainable one. Conclusions: The apron accident shows that safety failures stem not only from individual errors but also from the interaction of human, equipment, and supervisory factors. Integrating ORLIO and AMC supervision effectively enhances safety awareness and procedural discipline. Limitations: The study is limited to one airport, with qualitative data that may involve subjectivity. It focuses on operational staff, excluding higher management, and does not assess long-term impacts quantitatively. Contribution: The study was limited to one airport, so findings may not represent all contexts. It contributes to aviation safety management by demonstrating how combining human error evaluation and AMC supervision strengthens apron safety culture, offering practical insights for airport authorities and regulators.

The oxygen mask system on an aircraft is one of the important elements in maintaining the safety of passengers and crew in emergency situations, especially when there is a loss of cabin pressure. This study aims to examine the effectiveness and working mechanism of the oxygen mask system on classic Boeing aircraft, namely the Boeing 737-300, 737-400, and 737-500, during an emergency. The method used in this study is descriptive qualitative, with data collection techniques through interviews, observations, and literature studies. The results of this oxygen mask system study involved various units on the aircraft, including the Passenger Service Unit (PSU), Restroom Service Unit (LSU), and Attendant Service Unit (ASU). Oxygen in the aircraft is supplied from a cylinder through a pressure regulator, and the oxygen mask is automatically released when the cabin pressure drops below a certain threshold. In addition, the oxygen system can also be activated manually by the flight crew. One of the challenges is passenger confusion regarding the correct use of oxygen masks. This study also examines applicable safety regulations as set by the FAA and ICAO, to ensure that the oxygen system functions optimally in an emergency. The study also provides recommendations to improve routine training for cabin crew in handling oxygen mask systems and other safety procedures.

This article discusses the performance analysis of the CFM56-3-B1 turbofan engine used on the Boeing 737-300 aircraft under various operational conditions. This study was conducted to understand the engine performance under different flight conditions, such as minimum idle, approach idle, maximum continuous, and take off. This study was conducted using a qualitative method using a descriptive approach and literature study. The results of the analysis prove that the performance of the fan, booster, and high-pressure compressor (HPC) is higher than its ideal value due to compressor imbalance and leakage that causes an increase in compression temperature. Furthermore, it was found that during the take-off process the thermal efficiency became high with an actual efficiency of 37%, but still lower than the ideal efficiency of 47%, which was caused by material friction and environmental factors. While the maximum thrust was achieved thanks to the combination of hot and cold nozzle designs. The conclusion shows that engine efficiency is affected by material friction and environmental conditions, which have an impact on reducing thermal efficiency by 9.59%. Suggestions are given to improve thermal efficiency and thrust by optimizing airflow and engine cooling.

Hydroplaning is one of the causes of aircraft accidents during takeoff or landing. This study aims to examine the phenomenon of hydroplaning on the performance of the Boeing 737 aircraft, especially during takeoff and landing. Hydroplaning occurs when the air layer on the runway reduces friction between the aircraft wheels and the runway surface, which can disrupt stability and increase the aircraft's stopping distance. The research approach in this study uses a qualitative approach and the analysis used is a literature study from indexed scientific journals, textbooks, research reports, and other reliable sources. The results of this study, this study states that hydroplaning has a high effect on the performance of the Boeing 737 aircraft, especially when landing on a wet runway. Hydroplaning can reduce the effectiveness of aircraft braking and increase stopping distance substantially. Therefore, it is important to consider the air thickness factor and ensure speed control procedure to reduce the risk of hydroplaning. As well as the shape of the tire threads which can also reduce the height when landing or taking off

This study compares fixed-wing and rotary-wing aircraft in terms of flight efficiency, maneuverability, and operational function by addressing the lack of an integrated framework for mission-based aircraft comparison. A systematic literature-based comparative analysis was conducted using aerodynamics textbooks, aviation handbooks, technical references, regulatory documents, and recent scholarly articles. The analysis was structured around three parameters: flight efficiency, including energy consumption, cruising speed, and range; maneuverability, including takeoff and landing capability, hovering, and movement flexibility; and operational function, including mission suitability and operating environment. The findings show that fixed-wing aircraft provide higher cruise efficiency, greater range, and better payload effectiveness because lift is generated through forward motion over fixed airfoils. In contrast, rotary-wing aircraft offer superior maneuverability, vertical takeoff and landing, and hovering capability, making them more suitable for confined-area, emergency, and point-access missions. The novelty of this study lies in its structured analytical matrix, which clarifies the trade-off between cruise efficiency and spatial flexibility. The study concludes that neither aircraft type is universally superior; effectiveness depends on the alignment between aerodynamic characteristics, operational constraints, and mission requirements.
