The aircraft that used in this research is Grob G 120TP-A. Purpose of this research is support planning costs for scheduled maintenance in the period of 2020 and forecast the maintenance costs on the PI-600 flight hours for the period 2021, so that the aircraft is always in a state of airworthiness in order to support the implementation of operational activities as a training aircraft for the Indonesian Air Force. Maintenance costs on Periodic Inspection 600 flight hours of Grob G 120 TP-A aircraft in 2020 include employee salaries, spare parts, consumable materials, and fuel costs. Forecasting maintenance costs using the trend exponential method which uses maintenance cost data from 2016 to 2020. The results of the 600 flight hours of periodic inspection maintenance costs are Rp.476.527.879,92.and the results of forecasting maintenance costs for the Periodic Inspection 600 Flying Hours of the Grob G 120 TP-A aircraft using the trend least square method for the 2021 fiscal year is Rp. 408.667.919,9.

The development of the number of vehicles exceeding the capacity of highways in urban areas causes frequent traffic jams and increases the risk of accidents. This often happens during year-end holidays and Eid holidays. So it is very necessary to monitor traffic density during the annual holiday period to reduce the number of fatalities due to traffic accidents. Monitoring traffic density using helicopters is expensive because of the high fuel consumption and maintenance. So we need a new alternative, namely using Unmanned Aircraft (PUNA) because it is easy to operate and cheap to maintain. So it is very necessary to design PUNA for traffic density monitoring missions. Aircraft for this purpose are classified as small because the payload, namely the camera, only weighs 2 kg. Study obtained the following results: fuselas/body length 1.94 m, wingspan 1.46 m, airfoil NACA 2412. engine OS MAX-40FX, engine located in the nose, take-off Gross Weight 6.11 kg, material weight 321.09 grams, use an Oblique Camera type camera, the camera weight is 2 kg, and the camera position is 3 ft from the nose.

The use of helicopters is very useful for Indonesia's natural conditions which is in the form of islands. In order to support the helicopter's capabilities, an AFCS actuator or automatic flight control system actuator is needed to make the flight automatically. Therefore, the author tries to conduct a reliability analysis to determine the level of reliability of the AFCS Actuator component in S-76 helicopter. The method used to conduct the analysis is the Weibull distribution method, which is one of several methods that are often used. The main objective is to determine the level of reliability and characteristics of the failure modes that often occur in these components. By analyzing at the results of calculations and types of failures, it can be seen the types of effective treatments to be applied to the AFCS Actuator component.

Maintenance is all activities undertaken to maintain the aircraft, its aircraft components and equipment in an air condition including inspection, repair, servicing, overhaul and part change. To be able to perform maintenance properly, every aircraft is required to have a maintenance program. . Batam Aero Technic (BAT) handles MRO work on Airbus A320-214 aircraft with registration number PK-LUM. By analyzing the results of the aircraft maintenance planning to find out the comparison of the results of the planning with the implementation of maintenance. This can maximize the implementation of future maintenance so as not to interfere with aircraft flight operations at Batam Aero Technic (BAT). Before carrying out the treatment process, you should do the planning in advance to ensure that the treatment process runs in accordance with the planning made. To find out the treatment process is running in accordance with its planning or not, it will be analyzed using a fiishbone diagram. Fishbone diagrams are generally used in the stage of identifying problems and determining the cause of the problem. This treatment planning analsis process includes analysis of C01 check care implementation, evaluation of the implementation of C01 check treatment program, treatment delay solution, and C01 check care planning. Then from the results of the analysis the author obtained the cause of delays that occur in the field that is difficult to control such as the problem of delays in the availability of materials / spare parts where ordering and delivery time is needed. Therefore the authors propose to multiply the estimated manhours by 2.5 as an alternative to the anticipation of delayed completion of treatment. This is done to minimize the occurrence of delays in manhours on the ground.

The engine test bed is a tool used for testing in the development of new aircraft when it is installed into the aircraft to determine the capabilities of each engine. This engine test bed research aims to meet the needs of the learning process in supporting the practicum. By determining the geometry, modeling, material selection, manufacture, and testing of the engine test bed it will be known that the engine performance is good before use. The method used is a practical and analytical method to analyze the data that has been obtained from the test. The object of research used in this study is a dle-55cc engine. based on the results of testing the results of the thrust that compares with the static value of the thrust calculator, the average difference is obtained. From the results of the comparison of errors on the test equipment, the 22×8 propeller (4.5cm chord) obtained an average error of 4.178%. While the propeller 22×8 (chord 5cm) the error generated is 3.719% and from the value of fuel consumption obtained it produces 588,600-20,708 (N/kW.hr) this shows a good level of decline, so the engine used is more efficient in its use. From the test results, it can be said that the engine test bed has accuracy and can produce good engine performance to be used as a testing and other learning tool.

Bandar Udara Tanjung Api Ampana merupakan bandara yang cukup tingkat pelayanan terhadap arus penumpang dan barang yang digunakan untuk penerbangan ke berbagai wilayah di kota Ampana – Palu – Makasar. Dengan kebutuhan operasional penerbangan yang padat, kemampuan kapasitas muat pesawat yang diijinkan dan kekuatan runway dalam menerima pembebanan pesawat pada saat takeoff maupun landing. Maka penelitian ini dititik beratkan pada analisa berat operasional pesawat terbang terhadap kemampuan kekuatan runway di Bandar Udara Tanjung Api Ampana dengan menggunakan perhitungan ACN – PCN. Metode yang digunakan adalah metode ACN-PCN serta metode ARFL. Hasil menunjukkan hubungan antara berat take-off pesawat, PCN, serta panjang landasan. Pada analisa maksimum berat operasional yang dibatasi PCN didapatkan nilai maksimum yang diijinkan di Bandara tersebut dengan batasan kekuatan runway sesuai dengan jenis dan tipe pesawatnya. Hasil analisa runway strength didapatkan pada semua jenis dan tipe pesawat sesuai dengan operasional penerbangan di Bandar Udara Tanjung Api Ampana dapat menggunakan nilai maximum takeoff mass yang telah ditetapkan pada Tabel ACN Jeppesen. Dan berdasarkan analisis, panjang runway untuk pesawat ATR 500, CESSNA 208, dan HERCULES C-130 dapat dilayani oleh Bandara Tanjung Api Ampana dengan panjang runway nya. Agar pesawat jenis tersebut dapat take-off dan landing dengan aman.
