Rany Adiliawijaya Putriekapuja — 2024-06-30

Mental workload is a workload that is subjective and is owned by individuals in the work sector with a high-risk level of work. Air traffic control (ATC) personnel at the Jakarta Air Traffic Service Center (JATSC) are one of them. This problem needs to be highlighted because the level of air traffic density has been increasing compared to pandemic conditions. It now becomes a “new” habit that needs to be readjusted for JATSC Air Traffic Controllers (ATC) since 2021 (post-pandemic). Thus, this can create a separate mental workload for ATC personnel. The objective of the research to evaluate the mental workload of air traffic services during the post-covid-19 pandemic at JATSC using the Subjective Workload Assessment Technique (SWAT) method. The final result of the research is that ATC personnel are very concerned with the time load factor (Time) in carrying out air traffic service duties. A total of 16.67% of personnel emphasized the stress workload factor, and 8.33% emphasized the mental effort workload factor in carrying out their duties. The final score of the SWAT test was 46.2 in the afternoon shift and 48.6 in the procedural control task which indicated that the ATC personnel felt burdened with the afternoon shift and procedural control tasks.

Rossi Peter Simanjuntak — 2024-06-30

Fire is a disaster that often occurs in society, resulting in material loss and can cause loss of life. In order to reduce the impact caused by fire incidents, early detection is needed to prevent fires from occurring. In this research, a fire detection system was built by detecting the temperature and smoke contained in a room. The detection system uses a DS18B20 temperature sensor and an MQ135 smoke sensor connected to an ESP32 microcontroller connected to an LED layer. The fire detection system is monitored via a smartphone connected using the blynk application. The fire detection system is conditioned to detect temperatures > 450C and/or detect smoke > 600 ppm. When the temperature sensor detects that the temperature is > 450C and/or the smoke sensor detects that the smoke is > 600 ppm, the buzzer will sound and a fire warning notification will be displayed on the smartphone in real time. From the experimental results, it was found that when the temperature sensor detected a temperature of 48.90C, the buzzer immediately sounded and a temperature of 48.90C appeared on the smartphone and a fire warning notification on the smartphone in real time. An experiment was also carried out to detect the presence of smoke, when the smoke sensor detected 669 ppm, a buzzer immediately sounded and appeared on the smartphone, 669 ppm smoke, and a fire warning notification on the smartphone in real time

Noise in the workplace is a health issue in several countries. Similarly, in the aerospace industry, advanced aircraft, whether for civilian transportation or military purposes, pose risks due to exposure to aircraft noise, which passengers are continuously subjected to at relatively higher intensities and for prolonged periods. The problem of this research is to identify, reduce, and prevent the impact of aircraft noise and compliance with the use of personal protective equipment (PPE) on hearing impairment among cadet pilots at the Indonesian Aviation Academy in Banyuwangi. The research objective includes collecting medical records of 57 cadets, measuring aircraft noise levels, and conducting a questionnaire survey. The method used in this study is descriptive quantitative, with 57 respondents. Data analysis was performed to determine the compliance of cadets with PPE usage at the Indonesian Aviation Academy in Banyuwangi. The results show that the noise produced by the aircraft operated by the academy exceeds the permissible noise level (PNL), and the questionnaire results indicate low compliance with PPE usage. However, medical record data reveal that the majority of cadets still have normal hearing, with only 12.3% or 7 respondents categorized as having mild hearing impairment. These findings imply a positive and significant influence of aircraft noise level and PPE compliance on hearing impairment among trainees.
