Abstract

Considering the increasing use of security and surveillance systems, moving object tracking systems are an interesting research topic in the field of computer vision. In general, a moving object tracking system consists of two integrated parts, namely the video tracking part that predicts the position of the target in the image plane, and the visual servo part that controls the movement of the camera following the movement of objects in the image plane. For tracking purposes, the camera is used as a visual sensor and applied to a 2-DOF (yaw-pitch) manipulator platform with an eye-in-hand camera configuration. Although its operation is relatively simple, the yaw-pitch camera platform still needs a good control method to improve its performance. In this study, we propose a moving object tracking system on a prototype yaw-pitch platform. A m-synthesis controller was used to control the movement of the visual servo part and keep the target in the center of the image plane. The experimental results showed relatively good results from the proposed system to work in real-time conditions with high tracking accuracy in both indoor and outdoor environments.

Abstract

Penelitian ini menganalisis perencanaan bahan bakar ETOPS untuk pesawat Airbus A330-343 pada rute Jakarta (CGK) ke Jeddah (JED) dengan membandingkan waktu pengalihan 90 menit dan 120 menit dalam empat kasus penerbangan yaitu standar, kehilangan tekanan, kegagalan mesin, dan kombinasi kehilangan tekanan dengan kegagalan mesin. Metodologi standar industri digunakan untuk menghitung kebutuhan bahan bakar, kapasitas muatan, dan durasi penerbangan untuk setiap skenario. Hasil menunjukkan bahwa waktu pengalihan 120 menit umumnya menawarkan keuntungan dalam efisiensi bahan bakar dan kapasitas muatan. Rencana bahan bakar standar untuk pengalihan 120 menit membutuhkan 63.790 kg bahan bakar, dibandingkan dengan 64.689 kg untuk skenario 90 menit. Kasus kehilangan tekanan memerlukan konsumsi bahan bakar tertinggi di kedua skenario. Waktu pengalihan 120 menit juga memungkinkan jalur penerbangan langsung, mengurangi durasi penerbangan keseluruhan dalam sebagian besar kasus. Penelitian ini memberikan wawasan tentang optimalisasi perencanaan bahan bakar ETOPS untuk operasi pesawat bermesin ganda jarak jauh, berpotensi meningkatkan efisiensi operasional dan kinerja ekonomi dengan tetap mempertahankan standar keselamatan dalam penerbangan komersial.

Abstract

Airplane characteristics are interesting to analyze. The characteristics are shown as aerodynamic, structural and propulsion performance which further shows how economical the aircraft is compared to other aircraft. With the development of automatic dependent surveillance - broadcast (ADS-B), open source commercial aircraft flight data can be obtained easily. This study is performed to develop algorithm that can be used to predict aircraft aerodynamic coefficients. The algorithm is a collection of equations developed and simplified in previous studies. It is then used to estimate mass, lift, drag, and thrust forces, lift and drag coefficients, as well as fuel flow of an aircraft throughout the flight based on open source flight data, such as Flightradar24. The resulting lift and drag coefficients from the application of this algorithm are reasonably close within 9 – 14% compared to available references. Flightradar24 data is actually quite accurate for further flight performance analysis.

Abstract

Nowadays, many airlines in modern aviation utilize an Electronic Flight Bag (EFB) during flight to replace traditional paper-based systems. Considering the importance of aircraft weight and balance calculation to flight operations, the flight mission of X-123 (a small turboprop aircraft) and the current EFB market, research on weight and balance application development of X-123 on EFB in Indonesia is conducted. The research aimed to develop the application according to Indonesian regulations and to examine the weight and balance characteristics of X-123 through several simulations in a programming language, Python. Furthermore, Staff Instruction 8900 - 3.3 is analyzed to identify the factors that should be considered in EFB development. The global architecture design and substantial features are, then, proposed as an initial EFB development. In the global architecture design, the utilization of a gateway becomes important as a connection between the EFB developer and the client, providing aircraft data changes flexibility to the client. Moreover, the calculation formula is completely discussed in the calculation modules as a substantial feature and implemented in the simulation. According to simulation results, the payload weight and payload distribution changes can affect significantly the CG location. It is recommended to weigh and assign the payload before flight to ensure flight operation safety. In addition, the proposal of the architecture design and substantial features can be used as a reference and further developed by the Indonesian aviation companies.

Abstract

The technology of Unmanned Aerial Vehicles (UAVs), or drones, has rapidly evolved over the years, taking on various missions such as delivery, agriculture, mapping, surveillance, firefighting, and more. With the expanding functions of drones, the operational areas of UAVs also increase. However, there are restricted locations for UAV operations, one of which is an airport. Operating UAVs in controlled airspace requires permission from the government and local regulators. Moreover, a reliable communication system is crucial to support operations and prevent failures. This paper discussed the development of a communication system between UAV Ground Control pilots and Air Traffic Control (ATC) operators. The system utilizes strategic and tactical messages, developing the UAV communication system architecture based on the Controller Pilot Data Link Communication (CPDLC) standard operating procedures. This involved the design of the UAV Ground Control Station (GCS) communication system and the analysis of transmission power. The CPDLC system is a text-based communication system using the internet to send messages to ATC at an airport. The research methods included literature studies, collecting CPDLC messages based on documents (GOLD), developing the UAV communication system architecture, creating strategic communication standard operating procedures, designing the communication system interface on the GCS, and performing power calculations using link budget analysis. The research results indicate that the transmission power, calculated using the link budget at a distance of 100 km, is 17 dBm for payload communication and 15 dBm for telemetry communication, both meeting the minimum link margin standard of 15 dBm.

Abstract

In order for a satellite to achieve a sun-synchronous orbit (SSO), it must have a nodal precession rate equal to the revolution rate of the Earth around the Sun. However, sun-synchronous satellites generally encounter significant perturbations, which lead the local time of the satellite to drift gradually. In this research, the author analyzed potential maneuvers to maintain the local time of an SSO satellite for 5 years of operation of LAPAN-A4 satellite. The analysis was conducted by simulation using GMAT (General Mission & Analysis Tools) software with the LAPAN-A4 satellite as a case study. Furthermore, this research also attempted to find the optimum maneuvering period for each potential maneuver. The results showed that the RAAN correction maneuver is ineffective. It was also found that the most optimum maneuvering plan obtained from this research was a semi-major axis correction maneuver with 4 month maneuvering period with a particular correction targeting strategy.

Abstract

This study evaluates the efficiency of approach procedures at Sam Ratulangi International Airport-Manado by comparing Required Navigation Performance (RNP) under Performance-Based Navigation (PBN) with the Instrument Landing System (ILS) as a conventional procedure. A simulation using the BlueSky ATM Simulator was conducted with 30 aircraft instances for each approach, utilizing real-time FlightRadar24 speed data to ensure operational realism. The analysis focused on three key metrics: distance flown, time spent, and fuel consumption. Results show that implementing of PBN procedures reduces distance flown by 15%, flight time by 15% and fuel consumption by 14% compared to ILS, demonstrating improved operational efficiency. This research provides a quantitative assessment of PBN systems’ effectiveness in optimizing approach procedures, supporting aviation sustainability, and reducing operational costs.

Abstract

This study examines the operational efficiency of the Jakarta–Makassar (CGK UPG) route, one of Indonesia’s busiest domestic corridors, by integrating historical ADS B data analysis with stochastic simulation. Flight trajectories obtained from FlightAware were processed through data cleaning, standardization, Principal Component Analysis (PCA), and K-Means Clustering to extract a representative data-driven trajectory. This trajectory was evaluated alongside the RNAV T-5 and conventional VOR/NDB routes documented in AIRAC AIP AMDT 162. All routes were assessed using 300 Monte-Carlo simulations in the BlueSky ATM Simulator, incorporating randomized variations in cruise speed and altitude to reflect operational uncertainty. Performance indicators included flight distance, travel time, fuel consumption, and CO₂ emissions. Results show that the data-driven trajectory offers shorter distance and flight duration, requiring less fuel and producing lower emissions compared to the two procedural routes. These findings demonstrate that trajectory extraction based on historical data can produce more efficient flight paths and support the implementation of Trajectory-Based Operations (TBO) within Indonesia’s domestic airspace. The approach also contributes to national sustainability efforts by enabling potential reductions in carbon emissions from the aviation sector.

Abstract

This study investigates how aircraft speed and altitude at threshold crossing influence Runway Occupancy Time Landing (ROTL) on Runway 06 at Soekarno–Hatta International Airport. A dataset of 2,000 ADS-B landing trajectories from Flightradar24 was analyzed to quantify empirical relationships between threshold parameters and ROTL. The 5% lowest ROTL flights showed substantially higher threshold speeds than the 5% highest ROTL flights, while threshold altitude remained nearly constant, indicating that speed is the dominant operational driver of runway occupancy. A regression-based scoring method was used to identify a representative efficient reference flight, which then served as the baseline for stochastic simulation in the BlueSky ATM Simulator. Threshold speed and altitude were sampled from normal distributions calibrated to the efficient group, and 300 simulated landings were generated. The simulation reproduced efficient operations with a mean ROTL of 51.77 s and a narrow 95% confidence interval of 51.69–51.85 s. The results support a practical recommendation to standardize threshold speed and deceleration profiles as a low-cost strategy to reduce ROTL without infrastructure modification.
