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.

Students may experience digital fatigue as a result of substantial increases in academic workload and heavy reliance on digital technologies for learning. This study aims to analyze the effects of academic workload and digital fatigue on students’ academic achievement. A quantitative approach using survey techniques was used for this study, involving 200 students from the secondary school level. A questionnaire was used to collect data, which was then analyzed using multiple linear regression. The results showed a negative relationship between students’ academic achievement and workload, indicating that students’ academic achievement decreased in relation to the number of tasks they were asked to complete; this means that the more academic tasks students had to complete, the lower their academic achievement. The main factor that plays a role in this relationship is digital fatigue, which arises from the excessive use of digital devices in the learning process. Digital fatigue results in mental and physical fatigue, thus exacerbating the impact of academic pressure on students’ achievement. Digital fatigue occurs when students are exposed to digital device screens for too long without sufficient breaks. Common symptoms include eye fatigue, difficulty concentrating, sleep disturbances, and increased levels of stress and anxiety. In the long term, this condition can lead to decreased motivation to learn and negatively impact students’ emotional and psychological well-being. Effective strategies to reduce digital fatigue, such as better time management, variety in learning methods, and adequate breaks in academic activities, are needed, and it is important to provide students with balanced academic tasks so that they are not overburdened. Implementing these steps will help students focus on their studies without negatively impacting their emotional or psychological well-being.
