Abstract

Noise is a sound that causes sound violence and disturbs humans. In the aviation industry, noise affects flight safety and success because it can interfere with the concentration and performance of flight cadets. In addition, high intensity can also cause stress and fatigue in flight cadets, reducing their ability to maintain focus and respond to critical situations. This study aimed to analyze the impact of noise produced by engine sounds and radio signals on pilots. The results of this study on the aircraft dashbord sound noise value is greater because the aircraft dashbord clan is located adjacent to the engine while the smallest noise value is found in data retrieval in the back seat because it is farther from the engine. The data collection carried out produces output in the form of data resulting from the effect of engine noise on cadets. Keywords: noise,cadets,engine sound

Abstract

Avgas fuel consumption on Cessna trainer aircraft is very high. However, there has been little research regarding spray impacts in Cessna aircraft engines. The phenomenon of avgas spray colliding with the cylinder wall may occur during fuel injection, resulting in a changed spray radius and height, which will affect the mixing of fuel and air. In several aspects, this affects engine performance and exhaust emissions on Cessna aircraft. This research aims to determine and study the phenomenon of spray impact on avgas-fueled aircraft engines. The fuel spray in the study occurred in the combustion chamber using pressure from a fuel hand pump whose pressure was supplied from a compressor with a pressure adjusted to the original pressure on the aircraft, namely 2 Bar (30 Psi). The experiments in this research used a high-speed camera system to study the phenomenon of avgas spray on walls to get better spray distribution. The results of this research were processed using the CFD application. The result of this research is that the greater the pressure, the more concentrated the resulting jet will be on the jet wall so that the atomization of the fuel jet will be dispersed. When the burst occurs, a change of 3.80e+00 occurs compared to other burst pressures.

Abstract

The exponential growth of e-commerce has intensified challenges in last-mile delivery logistics, making sustainability a critical priority for researchers, policymakers, and industry practitioners. This study synthesizes existing literature on sustainable practices in last-mile logistics, focusing on economic, environmental, social, and technological dimensions. A narrative review approach was employed, drawing from academic databases such as Scopus, Web of Science, and Google Scholar. Literature was selected using targeted keywords and inclusion criteria to ensure comprehensive coverage of practices ranging from cost efficiency strategies to technological innovations. The results reveal that sustainable logistics practices, such as electric vehicle adoption, route optimization, and crowd logistics, can reduce operational costs, improve customer satisfaction, and decrease carbon emissions. However, disparities between developed and developing countries highlight systemic challenges, including inadequate infrastructure, limited regulatory support, and varying consumer preferences. Social outcomes, including the welfare of couriers and improvements in urban air quality, emphasize the broader societal benefits of sustainability, though labor protections remain underexplored in the literature. Technological advances, particularly GIS-based systems and autonomous vehicles, offer transformative potential but require supportive policy frameworks for effective implementation. The discussion highlights the importance of systemic factors—policy, regulation, and infrastructure—in shaping adoption. This review concludes that sustainable last-mile logistics is essential for aligning economic growth with ecological responsibility and social equity, recommending targeted policies, cross-sector collaboration, and longitudinal research to address current limitations.

Abstract

The rapid emergence of Industry 4.0 has reshaped supply chain management by introducing advanced digital technologies such as artificial intelligence, blockchain, Internet of Things, and big data analytics. This study aims to explore how the integration of these technologies influences efficiency, resilience, and sustainability in global supply chains. A systematic literature review was conducted using major academic databases, including Scopus, Web of Science, and Google Scholar, applying carefully selected keywords to identify relevant studies published between 2010 and 2025. Inclusion criteria focused on empirical, conceptual, and review studies addressing digital transformation in supply chain management, while irrelevant and non-peer-reviewed sources were excluded. Results indicate that IoT improves real-time visibility, AI enhances demand forecasting and risk management, blockchain strengthens transparency and trust, and big data analytics provides actionable insights for strategic decision-making. Collectively, these technologies reduce costs, mitigate risks, and support environmental sustainability by reducing waste, emissions, and inefficiencies. However, the findings also reveal systemic barriers, including inadequate infrastructure, limited resources in developing economies, regulatory inconsistencies, and organizational resistance to change. The discussion emphasizes the importance of supportive policies, public–private collaboration, and organizational cultural shifts to enable effective adoption. While theoretical models of digital supply chains are validated, empirical gaps remain, particularly concerning interoperability and long-term impacts. Future research should pursue longitudinal and sector-specific studies to address these limitations. Overall, digital transformation emerges as both a strategic necessity and a pathway toward inclusive, resilient, and sustainable supply chain management.

Abstract

Salah satu  modifikasi  yang  dilakukan pada pesawat untuk digunakan pada perairan yang sering kali melibatkan pemasangan Float sebagai pengganti landing  gear konvensional adalah seaplane. Namun, pemasangan Float pada seaplane juga dapat mempengaruhi karakteristik aerodinamik pesawat, khususnya hambatan (drag) yang dialami selama penerbangan sehingga menjadi masalah terhadap performa kinerja seaplane. Dengan adanya permasalahan tersebut, penelitian ini akan menganalisis hambatan air pada Cessna 172SP dengan Float tambahan menggunakan aplikasi Computational Fluid Dynamics (CFD). Metode yang digunakan dalam penelitian ini menggunakan Computational Fluid Dynamics (CFD) pada pesawat laut atau pesawat amfibi yang difokuskan untuk melihat bagaimana fluida (air dan udara) berinteraksi dengan permukaan pesawat yang mencakup analisis struktur hidrodinamika dan aerodinamika. Hasil analisis hambatan air pada Float pesawat Cessna 172 SP menunjukkan bahwa hambatan aerodinamik dan hambatan air berdampak pada kinerja pesawat terutama pada konsumsi bahan bakar, kecepatan terbang, dan kemampuan manuver.

Abstract

In urban and industrial regions, noise pollution is becoming a bigger environmental issue, particularly around airports. Excessive noise can have a number of detrimental effects on people's physical and mental well-being. The World Health Organization (WHO) states that extended exposure to noise can raise blood pressure, cause sleep disruptions, cause hearing loss, and increase the risk of cardiovascular disease. The fast expansion of air travel and heightened airport operations in Indonesia have made the noise issue worse. A lot of study has been done on how to lessen airport noise. More environmentally friendly natural solutions, such as the use of plants as noise barriers, have attracted attention as effective and sustainable alternatives. It is hoped that this research can provide practical and effective solutions that not only reduce noise but also support environmental sustainability. Thus, the results of this research will provide long-term benefits for the community around the airport and educational institutions such as the Indonesian Aviation Academy Banyuwangi. With an average noise reduction percentage of 46.79%, the study's results demonstrate the most notable decrease in noise levels. With a noise reduction of 29.54%, Tunas Merah comes in second. With a noise reduction of 23.94%, the TFan spruce comes in third. Noise is only decreased by 17.77% in the absence of barrier plants.

Abstract

This study investigated the effectiveness of three types of urban plants Pucuk Merah, Cemara Kifan, and Furing as noise barriers around airports. Using a 2-inch diameter sound tunnel along 6 meters with 3 mm PVC material, noise measurements were made at several points along the tunnel. The results showed that Furing plants had the most significant decrease in noise levels with an average noise reduction percentage of 46.79%. Pucuk Merah and Cemara TFan showed noise reductions of 29.54% and 23.94% respectively. Without the plant barrier, noise was only reduced by 17.77%. The characteristics of thick and dense leaves, as well as the complex structure of the plant, make Furing the most effective noise barrier. These results suggest that the use of plants, particularly furing, as a natural barrier around airports can significantly reduce the negative impact of noise and create a more comfortable environment.
