IOT-BASED STANDING WATER MONITORING SYSTEM FOR SUPPORTING PREVENTIVE MAINTENANCE IN AIRPORTS

Rehan Zikri Avian, Yayuk Suprihartini — Tue, 23 Jun 2026 00:00:00 +0000

Standing water on airport runways may reduce aircraft braking performance and increase the risk of hydroplaning during takeoff and landing. This study developed an IoT-based standing-water monitoring prototype to support preventive maintenance at Sultan Mahmud Badaruddin II International Airport in Palembang. An R&D method was applied. The system integrated JSN-SR04T ultrasonic sensors, GPS, Raspberry Pi, Arduino, and a camera with U-Net image segmentation, all connected to a web dashboard via HTTP. The dataset consisted of 1,200 runway water images divided into training (70%), validation (20%), and testing (10%) sets. Testing showed that the ultrasonic sensor achieved optimal accuracy at water depths above 2 cm, while the camera detected clear water up to 1.5 m and turbid water up to 2 m. User validation with five expert respondents yielded a feasibility score of 91%, categorized as excellent.

ANALYSIS OF INTERNATIONAL PASSENGERS’ SATISFACTION WITH THE AUTO GATE AT INTERNATIONAL AIRPORT

Tue, 23 Jun 2026 00:00:00 +0000

At Kualanamu International Airport, long queues at the immigration checkpoint prompted the adoption of the Auto Gate system for biometric self-service clearance. This study assessed the satisfaction level of 153 international passengers toward the Auto Gate and examined its effect on overall service quality. A descriptive quantitative approach was used, with questionnaires developed from the five SERVQUAL dimensions — tangibles, reliability, responsiveness, assurance, and empathy. Data were analyzed through descriptive statistics and simple linear regression. Results showed that passengers were generally satisfied across all five dimensions, with empathy receiving the highest rating. Simple linear regression confirmed a significant positive effect of Auto Gate usage on passenger satisfaction (R² = 0.616, p < 0.05), indicating that 61.6% of the variation in satisfaction is explained by Auto Gate usage.

SPEED TOOL INNOVATION FOR ROUTINE MAINTENANCE OF PERSONAL PROTECTIVE EQUIPMENT

M. Fadli Fadli, Thursina Handayani — Tue, 23 Jun 2026 00:00:00 +0000

Personal Protective Equipment (PPE) is critical for Airport Rescue and Fire Fighting (ARFF) personnel, yet its maintenance—particularly drying—remains manual and weather-dependent, creating risks of microbial growth and reduced protective effectiveness. This study developed the SPEED device (Effective, Efficient, and Powerful PPE Drying System) using a Research and Development (R&D) approach with the ADDIE model. Data were collected through observation, interviews, and expert validation at the ARFF Unit of Yogyakarta International Airport. SPEED integrates a heating element, exhaust fan, and UV-C lamp (344 W total) with automatic temperature and timer control. Expert validation by three ARFF practitioners and one academic validator yielded a score of 100% ("Very Feasible"). Performance testing confirmed that SPEED dries PPE within 15–60 minutes, up to 16 times faster than conventional sun-drying (180–240 minutes). This innovation improves PPE maintenance efficiency, ensures hygiene, and supports ARFF operational readiness.

FLIGHT LEVEL DETERMINATION: CRUISE ALTITUDE ON FUEL CONSUMPTION FOR AIRBUS A320CEO

Audry Farisqi Mosyam, Hafiz Ardian — Tue, 23 Jun 2026 00:00:00 +0000

Fuel efficiency is a critical issue in low-cost carrier operations, particularly on the medium-range Jakarta-Ambon route with high strategic value and load factors. This study evaluates the alignment between flight levels (FL) selected by dispatchers and the optimum FL based on aircraft weight, compares actual fuel consumption with Quick Determination (QDT) simulation results, and analyses how aircraft weight influences fuel efficiency. A descriptive qualitative approach was employed using document analysis, direct observation at the Operation Control Center (OCC), and in-depth interviews with three licensed flight dispatchers. Thirty actual Airbus A320 CEO flight plans for PT. Citilink Indonesia on the Jakarta-Ambon route in November 2024 were analyzed. Results indicate that 76.6% of actual FLs did not match the calculated optimum FL, yielding a fuel penalty of 500-1,558 kg per flight, with an average of approximately 900 kg per deviating flight. Implementing the QDT method enables more precise FL planning based on aircraft weight, contributing to measurable gains in operational fuel efficiency.

DESIGN & VALIDATION of SOLAR-POWERED STREET LIGHTING PROTOTYPE for AIRPORT DROP-OFF AREA

Muhammad Daru Balvero, Asep Muhamad Soleh — Tue, 23 Jun 2026 00:00:00 +0000

The drop-off area of Husein Sastranegara International Airport Bandung lacks street lighting, posing safety risks to passengers and vehicles. This study designed and validated a solar-powered lighting prototype for that area using a quantitative Research and Development (R&D) approach following the Borg & Gall model. Six stages were implemented: problem identification, data collection, product design, design validation, design revision, and product testing. Based on SNI 7391:2008 and PM 27/2018 requirements, a 1:10 scale prototype was constructed comprising a 10 Wp solar cell, 3 W LED lamp, 12 V/5 Ah battery, and Solar Charge Controller. Testing confirmed a solar cell output voltage of 19.30 V at peak irradiance (13:00 WIB, 32°C). Expert validation by three validators yielded an overall score of 86.5% (Very Good for device function; Good for device quality), confirming prototype feasibility for full-scale airport implementation.

DESIGN AND IMPLEMENTATION OF A MONITORING SYSTEM FOR DVOR EQUIPMENT STATUS USING LABVIEW

Kevin Raflyfasya, Muhammad Arif Sulaiman , Havan Hakim — Tue, 23 Jun 2026 00:00:00 +0000

The Doppler VHF Omnidirectional Range (DVOR) is a critical air navigation system that provides aircraft with azimuth information based on the Doppler effect. Monitoring of DVOR transmitter status at many facilities still relies on manual inspection or direct on-site intervention. This study designed and implemented a real-time DVOR status monitoring system in LabVIEW, integrated with RS-232 serial communication, and tested it on a THALES 432 DVOR at the CNS Laboratory of Politeknik Penerbangan Indonesia Curug. The system acquires serial data, parses the 5th byte of each data frame to classify the equipment status as Normal, Warning, or Alarm, and displays the results via color-coded LED indicators and a Waveform Chart, while logging timestamped records to an Excel file. Five functional tests across all three status conditions produced results fully consistent with the DVOR RCMS reference display, confirming the system's accuracy and reliability for real-time DVOR status monitoring.

DESIGN OF AN AUTOMATIC BRACKISH WATER FILLING SYSTEM IN A COLLECTING TANK FOR AIRPORT WATER MANAGEMENT

Rio Rizko — Tue, 23 Jun 2026 00:00:00 +0000

This study develops an automated brackish-water filling prototype for airport clean-water management at Jenderal Ahmad Yani Airport in Semarang. The existing manual filling process required technicians to continuously monitor water levels and operate the pump switch, resulting in inefficiency and an overflow risk. A Research and Development (R&D) approach using the Waterfall model (Analysis, Design, Implementation, and System Testing) was applied. The prototype integrates two water level sensors connected to an Outseal PLC V5 microcontroller and a relay to automatically control a submersible pump. When the lower sensor detects minimum water level, the pump activates; when the upper sensor confirms the tank is full, the pump stops automatically. Expert validation by three validators yielded an overall feasibility score of 86%, categorized as "Suitable for Use." The system successfully eliminates manual standby monitoring and reduces the risks of overflow and human error in airport water management operations.
