Tropical forest fires pose a serious threat to ecosystem sustainability, particularly in Kalimantan, which is prone to seasonal fires. Early detection is key to prevention efforts, but conventional and satellite-based monitoring methods often face limitations, particularly in identifying small-scale hotspots obscured by forest canopies. This study aims to test the effectiveness of integrating drone technology with thermal sensors in tropical forest monitoring as an early fire detection system. The research method uses a field study design with an experimental approach. Drone flights were conducted over tropical forest areas in Kalimantan, systematically capturing thermal imagery according to a predetermined flight path. Thermal image data were analyzed to identify hotspots, then compared with satellite hotspot data (MODIS and VIIRS). Field validation was also conducted through direct temperature measurements using a portable infrared thermometer. Data analysis involved comparing detection results, accuracy testing, and measuring system sensitivity with a confusion matrix. The results showed that drones with thermal sensors were able to detect more hotspots than satellites, with a higher level of accuracy compared to field validation results. For example, in several study areas, drones successfully identified small hotspots that were not detected by satellites. This confirms that drones with thermal sensors have high sensitivity and can be used as early detection tools for tropical forest fires. In conclusion, the integration of drone technology and thermal sensors has proven effective as a monitoring system that complements satellite-based methods. Further development using big data and machine learning, as well as cross-institutional collaboration, is needed for optimal implementation on a large scale.

The aviation industry is one of the service sectors. Due to its large number of users, safety is the primary concern in this industry. To ensure this safety, routine maintenance of operating aircraft is crucial, leading to the emergence of the aircraft maintenance industry. Due to the safety factors of the workpiece, installing ladders requires a significant workforce to supervise the workpiece, namely the aircraft itself, to prevent the ladder from hitting the aircraft body, which can result in COPQ (Cost Of Poor Quality). However, the use of many workers for ladder installation is considered inefficient because the maintenance process could be expedited if these workers could be utilized to install ladders on other parts of the aircraft. Therefore, if maintenance can be completed more quickly, the aircraft can return to flight sooner, meeting the airline's flight demands. Addressing this issue, this study aims to facilitate the ladder installation and removal process, thereby reducing the potential for collisions and ensuring the ladder is positioned at the required distance. This is achieved through ultrasonic sensors mounted on the work ladder, connected to a motor via Arduino Uno. The motor will stop when the input from the ultrasonic sensor reaches the predetermined distance. Additionally, if the aircraft tail moves while the ladder is installed, the system will automatically adjust the ladder's position to maintain the necessary distance, thus minimizing losses during aircraft maintenance.
