Abstract

One way to reduce the level of exhaust emissions is catalytic converter addition in the exhaust gas. The alternative material for catalytic converters is zeolite stone which is local material that is widely available in Gunungkidul Regency. This study aims to determine the effect of Gunungkidul zeolite catalytic converters on the absorption of motorbike engine exhaust emission. The side effects of motorbike performance is also evaluated. The results showed that the use of zeolite Gunungkidul stone as a catalytic converter can absorb CO (9,5% - 21,6%) and HC gases (15,5% - 63,9%) quite well and can meet the quality standards of motorcycle exhaust emissions but has side effects to reduce engine performance even though the decrease is relatively small (5%).

Abstract

Traffic Alert and Collision Avoidance Systems (TCAS) pada pesawat Boeing 737-800 NG memiliki fungsi utama untuk menghindari dan memberi peringatan dari suatu potensi tabrakan antar pesawat di udara. Dengan menganalisis berbagai input dari sinyal balasan pesawat lain dan kemudian memberikan peringatan visual dan/atau aural kepada crew berdasarkan perintah TA maupun TA/RA yang dipilih. Dengan demikian crew bisa mengambil suatu tindakan sehingga potensi kecelakaan bisa dihindari. Pada penelitian ini metode yang digunakan untuk penelitian adalah dengan melakukan observasi langsung dan melakukan penanganan kegagalan kerusakan pesawat Boeing 737-800 NG Garuda Indonesia di Hanggar 2 PT. GMF AeroAsia. Selain itu dilakukan analisis kegagalan pesawat dengan menggunakan metode fault tree analysis. Hasil  troubleshooting dan  fault  tree analysis  ditemukan kegagalan pada TCAS antenna, coaxial cable dan REU yang berpengaruh pada navigasi pesawat. Proses troubleshooting TCAS mengacu pada FIM Boeing 737-800 NG chapter 34-45 task 803 dan 804 dan juga FIM B737-800 NG chapter 23-51 task 803.

Abstract

Pesawat Grob G 120TP-A merupakan jenis pesawat latih dengan engine single turbo propeller. Dalam kinerja engine pesawat Grob G 120TP-A tersebut memiliki komponen yang dinamakan sistem beta untuk mengubah sudut riverse pada propeller dan menghasilkan gaya drag. Rata-rata kegagalan sistem beta banyak terjadi sebelum mecapai usia 3000 jam terbang. Berdasarkan hal tersebut dilakukan observasi kegagalan sistem beta pesawat Grob G 120TP-A dalam kurun waktu tahun 2016-2023, kemudian dilakukan analisis dengan Mean Time Between Failure (MTBF) dan dibandingkan dengan nilai probabilitas yang didapatkan dari pengalokasian Fault Tree Analysis (FTA). Hasil dari nilai mean time between failure paling tinggi pada sistem beta adalah terjadinya kegagalan N2 Fluctuate yang bernilai 961 cycle dan pesawat dengan nilai paling tinggi adalah pada pesawat LD 1201 dengan nilai 157 cycle, selanjutnya dibandingkan dengan probabilitas faul tree, maka kegagalan pada sistem beta dari total keseluruhan yang tidak bisa diterima hanya pada kegagalan vibration dan N2 fluctuate.

Abstract

Propeller yang diputar oleh engine dapat menghasilkan gaya dorong, karena bentuk blade propeller sendiri yang menyerupai airfoil pada wing pesawat jika dilihat dari penampangnya. Pada pesawat KT-1B Woong Bee, propeller yang digunakan adalah HC-E4N-2/E9512CB-1, jenis adjustable pitch dengan 4 blade. Agar propeller berfungsi optimal, putaran harus stabil untuk memastikan gaya dorong dan kenyamanan penerbangan. Vibration pada propeller sering disebabkan oleh ketidakseimbangan blade, yang bisa terjadi akibat perbedaan berat blade atau perbedaan angle of attack. Analisis kegagalan vibration propeller dilakukan dengan observasi dan data kegagalan dari pesawat KT-1B Woong Bee dalam tiga tahun terakhir (2021-2023). Data tersebut dianalisis menggunakan metode Fault Tree Analysis (FTA) untuk menemukan basic event vibration yang kemudian dianalisa kembali untuk menentukan modus kegagalan yang berupa different weight pada blade yang kemudian dilakukan penanganan berupa balancing propeller, yang mencakup penambahan beban pada blade untuk menyeimbangkan berat blade propeller.

Abstract

Usia jam terbang dan kalender menentukan batasan waktu pesawat C-130 Hercules melakukan pemeliharaan tingkat berat seperti pemeliharaan SIP, WFDI, dan CWBR. Dari kondisi pemeliharaan tingkat berat tersebut menyebabkan terjadinya penumpukkan perawatan yang dimana terjadinya penumpukkan perawatan dengan puncaknya yaitu pada tahun 2023 sebanyak 11 pesawat masih dalam melakukan perawatan berat. Sehingga perlu adanya metode untuk mengurangi penumpukkan pemeliharaan berat tersebut. Pada tugas akhir ini yaitu menganalisis untuk mengetahui nilai total kebutuhan manhours dalam pemeliharaan SIP menggunakan metode Critical Path Method (CPM) dan mengetahui nilai persentase efisiensi perbandingan. Dari hasil analisis dengan menggunakan metode Critical Path Method (CPM) didapati total manhours yaitu sebesar 12180 manhours dengan nilai persentase efisiensi perbandingan sebesar 32,63%.

Abstract

An Anti-icing system is a system that aims to prevent the formation of ice when the plane is in the air. The formation of ice in aircraft is of great concern because an airplane flight will pass through the atmosphere, which will experience the formation of the ice at a certain altitude. The formation of such ice will cause a hazard to the aircraft. So that the ice protection system, namely the anti-icing system, is very concerned so that it is always in a serviceable condition. In this study, direct observation and fault tree analysis were used to determine the cause of failure of the Boeing 737-800 NG anti-ice system engine and anti-icing cowl inlet. The results of the analysis using the fault tree analysis method obtained essential events, namely: actuator fails, electrical connector disconnected, Control Selenoid Trouble, Regulator Trouble, Sense Line Connector Trouble, Engine Fault, Engine Control Trouble, Engine Duct Trouble, Panel Buttom Problem, EICAS Module Problem, No Source Electricity, Negative Electrical Source, Wiring Problem.

Abstract

This study aims to analyze the increase in the payload capacity of the Airbus A320 at Radin Inten II International Airport Lampung using the Improve Climb approach. The Improve Climb approach focuses on optimizing the aircraft's climb path to enhance efficiency and payload capacity, particularly in airport conditions with high elevation and unfavorable weather. This study includes an analysis of the performance data of the Airbus A320. In addition, flight simulations were conducted taking into account factors such as wind speed, air temperature, and engine power. The results of this analysis are expected to provide recommendations regarding the optimization of flight schedules, passenger capacity, and improvements in operational efficiency at the airport. The results of the study indicate that by applying the Improve Climb approach, the aircraft's payload capacity can be increased by up to 3% without compromising safety. This opens up opportunities to increase the number of passengers.

Abstract

An airport is a facility where all stakeholders in the aviation industry converge, and its core product is “service,” which includes services for passengers, cargo, and aircraft. Customer satisfaction at airports is an essential outcome that must be delivered to all aviation industry stakeholders. This study aims to analyze the influence of service quality and marketing mix on customer trust, with customer satisfaction serving as an intervening variable at the airport. In reality, many airport service users still feel dissatisfied with both the services provided and the existing facilities. This is evident from various complaints submitted by users, indicating that they have not yet experienced satisfactory airport services. This research employs a quantitative method by distributing questionnaires to 100 respondents, consisting of domestic passengers at Minangkabau International Airport. The findings reveal that service quality and marketing mix have a significant partial and simultaneous effect on customer satisfaction. Furthermore, service quality, marketing mix, and customer satisfaction—both partially and simultaneously—have a significant influence on customer trust. However, the customer satisfaction variable is unable to mediate the relationship between service quality and the marketing mix toward customer trust.
