Abstract

Batas umur pemakaian setiap komponen life limited part (LLP) engine pesawat terbang bervariasi. Maka dari itu perlu adanya suatu monitoring untuk mengetahui sisa umur komponen agar tidak terlewat atau melebihi batas umur pemakaian yang telah ditentukan oleh pabrik. Jika suatu komponen sudah mendekati batas umur yang telah ditentukan, maka komponen tersebut wajib untuk diganti dengan yang baru, walaupun secara visual kondisi komponen tersebut terlihat masih bagus atau layak. Untuk mempermudah monitoring maka perlu dibuatkan ilustrasi engine dan tiga warna dengan menggunakan rumusan microsoft excel serta ditambahkan minimum remaining agar jarak pada shop visit tidak terlalu dekat, sehingga bisa meminimalisir waktu dari sebuah perencanaan shop visit. Kelebihan dari program ini adalah dapat monitoring remaining (cycles) category pada tanggal yang ingin ditentukan, Program ini perlu diuji pada kondisi operasional maintenance. berdasarkan hasil analisis, rumusan microsoft excel dengan ditambahkan ilustrasi engine dan tiga warna serta minimum remainning dapat diuji dalam mempermudah suatu monitoring.   Life limit in every aircraft engine life limited part (LLP) component is varyated. Therefore, a monitoring is needed to determine life status of component in order to monitor life limit of component so they not exceed limit specified by manufacturer. If a component almost reach specified life limit, so that component must be replaced with new component, although visually that component still in good condition. In order to make monitoring easier engine illustration with 3 color created using Microsoft excel formula and minimum remaining added to make time between shop visit not too close, so time for shop visit planning can be minimalize. Advantage of this program is monitoring on remaining (cycle) category on specified date, and disadvantage of this program is needed to be tested in maintenance operational. According to analysis, microsoft excel formula with engine illustration with 3 color and minimum remaining can be examined in order to make monitoring easier.

Abstract

Pelaksanaan pemeliharaan (maintenance) untuk berbagai sistem pada pesawat terbang mutlak diperlukan untuk menjaga kondisi pesawat agar selalu siap dan  aman pada saat dioperasikan. Program pemeliharaan dapat dibagi menjadi pemeliharaan terjadwal (schedule maintenance) yang bersifat preventif untuk mencegah terjadinya kegagalan dan pemeliharaan tidak terjadwal (unscheduled maintenance) yang berisfat korektif untuk memperbaiki komponen yang gagal agar kembali pada kondisi awal. Pemeliharaan preventif dapat mempengaruhi kehandalan komponen. Reliability mapping adalah salah satu metode untuk memonitor pengaruh pemeliharaan preventif terhadap kehandalan melalui cara grafis. Penelitian ini akan menggunakan reliability mapping dalam bentuk Microsoft Excel untuk evaluasi pelaksanaan schedule dan unschedule maintenance. Pada Studi kasus update navigation data base metode reliability mapping dapat menunjukan maintenance tepat waktu atau tidak. Studi kasus main wheel dapat menunjukan posisi main wheel yang memiliki kecenderungan interval penggantian paling pendek. Pada studi kasus ignition menunjukan bahwa maintenance A-check mempengaruhi kehandalan komponen dan dapat mencegah terjadinya unschedule maintenance.   Implementation of maintenance for various systems on the aircraft must be performed to maintain aircraft condition always ready and safe during operation. Maintenance program can be divided into schedule maintenance as preventive maintenance that prevents the component failure and unscheduled maintenance as corrective maintenance to repair the failed components to the initial conditions.

Abstract

Kontribusi industri transportasi udara sebesar 2% dari emisi CO2 dunia memerlukan usaha penurunan emisi dari pengembangan desain pesawat udara. Penurunan emisi dapat dilakukan dengan menurunkan konsumsi bahan bakar pada desain yang lebih baru dari pengembangan desain pesawat terbang. Perbandingan data spesifikasi dari B737 familly dan A320 dilakukan pada penelitian ini untuk menentukan kontribusi teknologi material ringan dan teknologi engine pada penurunan emisi. Perkembangan generasi desain yang lebih baru dari pesawat pada kelas yang sama menghasilkan peningkatan berat kosong (Operating Empty Weight, OEW), MTOW (Maximum Take Off Weight), dan persentase OEW/MTOW dibandingkan pesawat generasi sebelumnya. Perhitungan perkiraan konsumsi bahan bakar dari pesawat B737-300 dan B737-700 menunjukkan penurunan emisi dipengaruhi oleh perkembangan teknologi engine yang lebih hemat bahan bakar daripada perkembangan teknologi material ringan pada struktur pesawat terbang. Efektifitas penurunan emisi dipengaruhi oleh jarak terbang pesawat.         Air transport industry has 2% contribution in CO2 emission need emission reduction effort from aircraft design improvement. Emission reduction could be done by decrease fuel consumption for next aircraft design. Aircraft specification data among B737 and A320 family was compared to determine contribution of light aircraft material technology and engine technology for emission reduction. Aircraft with newer design have higher Operating Empty Weight, Maximum Take Off Weight, and percentage of OEW/MTOW than older design. Fuel consumption estimation between B737-300 and B737-700 shown emission reduction more affected by Engine technology improvement that reduce fuel consumption rather than light material technology for airframe. Reduction of emission also affected by flight distance.

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

Selain sebagai penghasil gaya angkat, sayap berfungsi menahan beban yangterjadi pada struktur pesawat, seperti beban geser, puntir dan lentur (bending). Dari semuabeban tersebut beban lentur (bending) merupakan beban terbesar yang diterima oleh sayap.Pengaturan beban bending merupakan salah satu faktor utama dalam mengurangi bebanyang dialami oleh sayap. Namun, nilai optimal yang ditunjukkan berlawanan antara di daratdan di udara, untuk memanfaatkan keadaan tersebut digunakan sistem fuel transfer loadalleviation. Fuel transfer load alleviation merupakan suatu sistem yang otomatismemindahkan fuel lebih banyak di tangki bagian dalam pada saat di darat dan berada di tangkibagian luar pada saat di udara sehingga efek dari beban bending dapat dikurangi. Bebanbending yang dihasilkan merupakan hasil penjumlahan antara distribusi berat dan distribusilift yang terjadi pada sayap sehingga untuk menghitung bending diperlukan data distribusiberat pada sayap. Penelitian ini bertujuan untuk mengetahui distribusi berat dan distribusi liftyang terjadi pada sayap pesawat Boeing 737-500. Nilai distribusi berat dan distribusi liftmenghasilkan optimasi moment pada dua keadaan yaitu, di darat dan di udara dengan tigavariasi fuel transfer yaitu, constant dengan nilai 40134,53 N, linier dengan nilai 48059,53 N,dan maximum dengan nilai 172386,50 N

Abstract

The lifting of the Restriction of Community Activities (PPKM) in January 2023 was the beginning of the aviation industry in Indonesia starting to rise marked by the emergence of new Maintenance Repair and Operations (MRO). Limited hangar space at MRO is a challenge in scheduling aircraft maintenance, setting the order of task cards that have been submitted by the airline and must be done in the maintenance project will be an illustration of how long this project will be done. MP item number 7122410504 contains Detailed Inspection of Aft Engine Mount Fail-Safe link is a maintenance job that can be done after the removal of Engine. The engine removal and installation process often takes more time and effort, potentially causing delays in the overall maintenance time. The purpose of this research is to make efficiency in the removal and installation process of the RR Trent 700 engine using the critical path method. The critical path method in analysing the stages of work in the maintenance process aims to identify and optimise resource allocation, so that maintenance time can be minimised and overall efficiency can be improved. The results showed that the application of the critical path method in the stages of engine removal and installation work resulted in a time efficiency of about 1,655 Hours so that the delay in work on the critical path became the main factor affecting the total duration of the engine removal and installation process.
