Abstract

The main battery on the CRJ-1000 aircraft is an important component in the aircraft's electrical system. The main battery functions as the main source of electric power when the aircraft is turned off or when the aircraft engine is not operating. If there is a failure in the aircraft's battery it can cause disruption to other systems so that the aircraft cannot fly or Aircraft on Ground (AOG). In Garuda Indonesia's CRJ-1000 aircraft battery, there were several findings where the battery failed before reaching the scheduled removal time. This study aims to analyze the reliability of the CRJ-1000 main battery on the Garuda Indonesia airline. The analytical method is carried out by collecting historical data on main battery failures and calculating the Mean Time Between Failure (MTBF) and Availability values for a certain period. In addition, an analysis was also carried out on maintenance procedures and replacement of the main battery carried out by Garuda Indonesia airline technicians. The results of the analysis show that the MTBF of the CRJ-1000 main battery on Garuda Indonesia airlines has a fairly good value, but there is a need for improvement in maintenance procedures and replacement of the main battery to increase availability. The recommendations proposed are evaluating the main battery maintenance and replacement procedures, as well as increasing the availability of main battery spare parts which can speed up repair times in failure situations.

Abstract

Air Force Bases (Lanud) in Indonesia have a crucial role in maintaining national security and defense, especially in supporting the operations of the Indonesian Air Force. This study aims to find the Minimum Spanning Tree network between Air Force Bases (Lanud) in Indonesia using the Minimum Spanning Tree (MST) method. Minimum Spanning Tree (MST) is used to connect all Lanud. By using the Minimal Spanning Tree Method analysis, it can provide an optimal solution by producing a minimum total travel distance with a direct connection procedure at the points (nodes) on a network. Contributing positively to operational activity planning, more effective use of resources, and rapid response in emergency situations. The data used in this study are secondary data, namely data on the distance between 44 Lanud in Indonesia obtained from Google Earth. This data uses nautical miles units. The data obtained is represented in the form of a matrix and graph, then the parameters used are determined. After that, the data is analyzed using a minimum spanning tree. The results of the Minimum Spanning Tree analysis show that the optimum network connecting 44 Air Force Bases has a total distance of 6664 NM, which increases the efficiency, readiness, and flexibility of the TNI AU's operational planning in responding to emergency situations by each air force base optimally. Most TNI AU aircraft are able to travel the minimum spanning tree network with the longest distance from Halu Oleo Air Force Base to El Tari Air Force Base of 371 NM, except for the SA-330 Puma aircraft which can only travel 300 NM.

Abstract

The Landing gear is a critical component of an aircraft that supports its weight and absorbs shocks during takeoff and landing, as well as reduces air resistance during flight. The Ground Lock is a crucial part that locks the Landing gear in place when the aircraft is parked to ensure stability. For educational purposes, a practical and portable model has been created that resembles the actual Landing gear, with dimensions adjusted for classroom use (31.5 cm x 21.2 cm x 18.4 cm). This model uses flexible hydraulic hoses and medical syringes as hydraulic pumps, with a frame made of strong, lightweight, and transparent aluminum and acrylic. Testing of the model shows that this hydraulic system is effective in simulating the locking and releasing of the Landing gear, with a time of 8.49 seconds, although it can vary depending on the operator. The advantages of this model include ease of operation, availability of easily obtainable materials, economical cost, and portability. Its drawbacks include inaccurate scale, material limitations, limited complexity, untested durability under extreme conditions, dependence on the operator, and the need for regular maintenance. Nonetheless, this model remains significant in aviation engineering education, helping students understand the Ground Lock main Landing gear mechanism through realistic simulations.

Abstract

An Indonesian airline, PT. XYZ, performs maintenance on its Boeing 777 aircraft equipped with General Electric GE90 engines at PT. GMF AeroAsia. The aircraft’s Engine Air Supply System utilizes a High Pressure Shutoff Valve (HPSOV) and a Pressure Regulating Shutoff Valve (PRSOV). Between 2019 and 2022, PT. XYZ's Boeing 777 fleet experienced 10 delays and 52 instances of HPSOV/PRSOV replacements due to valve sticking or seizing. This study aims to analyze the reliability of the HPSOV/PRSOV by calculating the Mean Time Between Failures (MTBF) and to optimize spare parts inventory management using the Economic Order Quantity (EOQ) method. The MTBF calculation yielded a value of 8,134.08 Flight Hours (FH). Additionally, the spare parts inventory analysis indicated that the most economical order quantity for each repair is 2 units, with a remaining inventory of 2 units. The total cost of the spare parts inventory is $3,033.66 USD. The findings of this study are expected to provide recommendations for PT. XYZ to improve spare parts inventory management and minimize the risk of delays in aircraft maintenance.

Abstract

Dalam tingkatan perindustrian, industri terbesar yang mungkin dibangun adalah industri berbasis riset. Sementara di lain pihak, sebagian riset yang dilakukan di perguruan tinggi tidak dapat terealisasi dalam skala industri yang diharapkan. Titik temu antara keduanya adalah jika komunikasi dan kerjasama perguruan tinggi dengan industri diperbaiki dan ditingkatkan. Sebagai upaya meningkatkan komunikasi dan kerja sama ini, sejak tahun 2014, Fakultas Teknologi Kedirgantaraan, Universitas Suryadarma (dalam proses perubahan nama menjadi Universitas Dirgantara Marsekal Suryadarma) melakukan beberapa pendekatan baik ke pihak industri maupun profesi. Untuk menggerakkan triple helix teknologi kedirgantaraan, dalam upaya tersebut dilibatkan juga pihak pemerintah sebagai regulator mendampingi proses ini. Kerja sama yang sudah dan sedang dilakukan adalah (i) dengan Learning Services, Garuda Maintenance Facility (GMF) AeroAsia untuk menyesuaikan kurikulum program studi di Fakultas Teknologi Kedirgantaraan dengan kebutuhan industri penerbangan, didahului dengan riset studi kurikulum dengan regulator Kementerian Perhubungan dan acuan KKNI dan SNPT; (ii) dengan industri pembuatan pesawat tanpa awak, didahului dengan riset rancang bangun; (iii) dengan industri hovercraft, didahului dengan riset rancang bangun; (iv) dengan lembaga sertifikasi profesi aviasi untuk mendukung riset dan industri dalam hal kompetensi pelaksananya dengan regulator BNSP.

Abstract

Aircraft performance can be reviewing by some scientific method. Analytic, numeric and experiment method are three methods that are commonly used. In fact, the research had been done by aircraft manufacturing when they done the design. However, analysis of the resulting data was never published to the mass and communication media as they relate to the interests of the manufacturing company itself. Thus the need for the work done in assessing the performance of aircraft designed and manufactured by several manufacturers. In this study conducted several analyzes of the performance of the NACA airfoil used on the wings of aircraft CN-235 (PT.DI), AIDC-xC2 (AIDC) and 212-Aviocar CASA (EADS-CASA) which has the same NACA airfoil that is 653- 218 but has the geometry and extent of the wing (mean aerodynamic chord / MAC) which is different to using simulation modeling software fluent. Modeling geometry Configuration varied into three configurations with variations in the angle of attack of -4º to 18º. The study concluded that the simulation with the same NACA airfoil with a variation in the length of the MAC will generate value CLmax differently to variations in angle of attack, the value of CL & CD differently to variations in angle of attack, and the value of the lift and drag differ also on the angle of attack.
